NOTE: A. To avoid removing concrete flooring, begin lineup leveling from the highest point of the store floor.

B. When wedges are involved in a lineup, set them first.All cases were leveled and joined prior to shipment to insure the closest possible fit when cases are joined in the field. When joining, use a carpenters level and shim legs accordingly. Case must be raised correctly, under legs where support is best, to prevent damage to case.

1. Check level of floor where cases are to be set. Determine the highest point of the floor; cases will be set off this point.

2. Set first case, and adjust legs over the highest part of the floor so that case is level. Prevent damage - case must be raised under leg or by use of 2x6 or 2x4 leg brace. Remove side and back leg braces after case is set.

3. Set second case as close as possible to the first case, and level case to the first using the instructions in step one.

4. Apply masking tape 1/8” in from end of case on inside and outside rear mullion on both cases to be joined.

Method: RGD Alignment for Line Ups1. Surface must be clean, dry, and free of debris. Apply

Devan Sealant to RGD case sides along joint faces. (See Figure 1)2. Identify Alignment/Bolting points provide as shown.

(See Figure below)3. Align and adjoin cases in line up configuration.4. Bolt cases together at Alignment/Bolting points

using provided hardware or equivalent hardware. BOLT HEX HEAD 3/8-16 X 3/4”

NUT TOP LOCK 3/8-24 ZINC Devan Sealant 255-25. Once bolting is complete. Apply silicone to wrapper

case joints. (See Figure below)

4. InstallationLocationThe refrigerated merchandisers have been designed for use only in air conditioned stores where temperature and humidity are maintained at or below 75°F and 55% relative humidity. DO NOT allow air conditioning, electric fans, ovens, open doors or windows (etc.) to create air currents around the merchandiser, as this will impair its correct operation.

DO NOT place Self Contained versionsof this case, having the electric evaporator pan,

underneath or adjacent to any flammable structureor structure housing flammable merchandise!

Uncrating the StandPlace the fixture as close to its permanent position as possible. Remove the top of the crate. Detach the walls from each other and remove from the skid. Unbolt the case from the skid. The fixture can now be lifted off the crate skid. Lift only at base of stand!

Exterior LoadingThese models have not been structurally designed to support excessive external loading. Do not walk on their tops; This could cause serious personal injury and damage to the fixture.

Setting and JoiningThe sectional construction of these models enable them to be joined in line to give the effect of one continuous display. A joint trim kit is supplied with each joint.

It is the contractor’s responsibility to installcase(s) according to local construction and

health codes.

LevelingIMPORTANT! IT IS IMPERATIVE THAT CASES BE LEVELED FROM FRONT TO BACK AND SIDE TO SIDE PRIOR TO JOINING. A LEVEL CASE IS NECESSARY TO INSURE PROPER OPERATION, WATER DRAINAGE, GLASS ALIGNMENT, AND OPERATION OF THE HINGES SUPPORTING THE GLASS. LEVELING THE CASE CORRECTLY WILL SOLVE MOST HINGE OPERATION PROBLEMS.

5. PlumbingWaste Outlet and P-TRAPThe waste outlet is located in the center, 8" from the front of the case.A 3/4” OD P-TRAP and threaded adapter are supplied with each fixture. The P-TRAP must be installed to prevent air leakage and insect entrance into the fixture.NOTE: PVC-DWV solvent cement is recommended. Follow the manufacturer’s instructions.Installing Condensate DrainPoorly or improperly installed condensate drains can seriously interfere with the operation of this refrigerator, and result in costly maintenance and product losses. Please follow the recommendations listed below when installing condensate drains to insure a proper installation:

1. Never use pipe for condensate drains smaller than the nominal diameter of the pipe or P-TRAP supplied with the case.

2. When connecting condensate drains, the P-TRAP must be used as part of the condensate drain to prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14” off the center of the case to allow use of the P-TRAP pipe section. Never use two water seals in series in any one line. Double P-TRAPS in series will cause a lock and prevent draining.

3. Always provide as much down hill slope (“fall”) as possible; 1/8” per foot is the preferred minimum. PVC pipe, when used, must be supported to maintain the 1/8” pitch and to prevent warping.

4. Avoid long runs of condensate drains. Long runs make it impossible to provide the “fall” necessary for good drainage.

5. Provide a suitable air break between the flood rim of the floor drain and outlet of condensate drain. 1” is ideal.6. Prevent condensate drains from freezing:

a. Do not install condensate drains in contact with non-insulated suction lines. Suction lines should be insulated with a non absorbent insulation material such as Armstrong’s Armaflex.

b. Where condensate drains are located in dead air spaces (between refrigerators or between a refrigerator and a wall), provide means to prevent freezing. The water seal should be insulated to prevent condensation.

RGD (Self Contained)The waste outlet and P-TRAP are the same as the remote except the case condensate drains to a pump assembly mounted to the bottom rear of the case. Condensate is pumped to the top of the water evap pan assembly. Hot air from the condenser is forced through the water evap assembly, evaporating the water. Any overflow from the water evap assembly is directed back to the pump assembly. It is critical that the case be level to keep the water evap assembly from overflowing!! The metal cover over the top of the condensing unit must be in place to force the hot condenser air through the water evap assembly.The condensate pump can be accessed through the front of the closeoff panel.

15

slave cylinder(s) are located within the electrical access panel(s).

Electronic Expansion Valve (Optional)A wide variety of electronic expansion valves and case controllers can be utilized. Please refer to EEV and controller manufacturers information sheet. Sensors for electronic expansion valves will be installed on the coil outlet, and in the discharge air. (Some supermarkets require a 3rd sensor in the return air). Case controllers will be located in the electrical raceway or under the case.

Thermostatic Expansion Valve LocationAn Alco balanced port expansion valve model is furnished as standard equipment, unless otherwise specified by customer. There is one expansion valve located on the left side of each evaporation coil under the bottom deck pans.Expansion Valve AdjustmentExpansion valves must be adjusted to fully feed the evaporator. Before attempting any adjustments, make sure the evaporator is either clear or very lightly covered with frost, and that the fixture is within 10°F of its expected operating temperature.

Measuring the Operating Superheat1. Determine the suction pressure with an accurate

pressure gauge at the evaporator outlet.2. From a refrigerant pressure temperature chart,

determine the saturation temperature at the observed suction pressure.

3. Measure the temperature of the suction gas at the thermostatic remote bulb location.

4. Subtract the saturation temperature obtained in step No. 2 from the temperature measured in step No. 3.

5. The difference is superheat.6. Set the superheat for 5°F - 7°F.

Condenser VentilationBe sure to supply adequate ventilation for the condenser in Self Contained units. Allow 212 square inches for units up to 1 h.p., and 260 for condenser units up to 1 1/2-1 3/4 h.p.

T-STAT LocationThe T-STATS are located within the electrical raceway. The raceway's location will remain under the front fascia of the case. In all cases, the T-STAT is located on the same side of the case. If you are looking at the case from the front, it is the right-hand side.

Refrigerant TypeThe standard refrigerant will be R-404A unless otherwise specified on the customer order. Check the serial plate on the case for information.

PipingThe refrigerant line outlets are located under the deck pans. Insulate suction lines to prevent condensation drippage.

Access PanelsAll electrical and drain access panels are clearly labeled on the deck of the Deli/Beverage case. The access for condensing units (in the self contained units) is located on the side of the stand, at the end. Ends of stand are fitted for removal, if condensing unit has to be taken out.

Refrigeration LinesLiquid Suction

3/8" O.D. 5/8" O.D. NOTE: The standard coil is piped at 5/8” (suction); however,

the store tie-in may vary depending on the number of coils and the draw the case has. Depending on the case setup, the connecting point in the store may be 5/8”, 7/8”, or 11/8”. Refer to the particular case you are hooking up.

Refrigerant lines should be sized as shown on the refrigeration legend furnished by the store.Install P-TRAPS (oil traps) at the base of all suction line vertical risers.Pressure drop can rob the system of capacity. To keep the pressure drop to a minimum, keep refrigerant line run as short as possible, using the minimum number of elbows. Where elbows are required, use long radius elbows only.

Control SettingsSee RGD technical data sheet for the appropriate settings for your merchandiser. Maintain these parameters to achieve near constant product temperatures. Product temperature should be measured first thing in the morning, after having been refrigerated overnight. For all multiplexing, defrost should be time terminated. Defrost times should be as follows: OFF CYCLE - Six times daily for 25 minutes. The number of defrosts per day should never change.The duration of the defrost cycle may be adjusted to meet conditions present at your location.

Access to TX Valves and Drain LinesMechanical - Remove product from end of case. Remove product racks. Remove refrigeration and drain access panels (labeled). TX valve (mechanical only) and drain are located under each access panel at end of the case.Electronic - The Electronic Expansion valve master and

Electrical Circuit IdentificationStandard lighting for all models will be full length fluorescent lamps located within the case at the top.The switch controlling the lights, the plug provided for digital scale, and the thermometer are located at the rear of the case mullion.The receptacle that is provided on the exterior back of these models is intended for computerized scales with a five amp maximum load, not for large motors or other high wattage appliances. It should be wired to a dedicated circuit.

BEFORE SERVICINGALWAYS DISCONNECT ELECTRICAL

POWER AT THE MAIN DISCONNECTWHEN SERVICING OR REPLACING ANY

ELECTRICAL COMPONENT.This includes (but not limited to) Fans, Heaters

Thermostats, and Lights.

Field Wiring and Serial Plate AmperageField Wiring must be sized for component amperes printed on the serial plate. Actual ampere draw may be less than specified. Field wiring from the refrigeration control panel to the merchandisers is required for refrigeration thermostats. Case amperes are listed on the wiring diagram, but always check the serial plate.

LED Driver LocationDrivers are located within the access panel that runs the length of the rear of the case. Refer to diagram on page 8.

8. Finishing Touches

If more than one RGD is being installed next to each other, the factory fitted continuous fascia may need to be installed. All fasciae rest on the top of their cases. The self contained fascia has a hook that needs to be slid through a gusset on the side of the case.

9. User InformationStockingImproper temperature and lighting will cause serious product loss. Discoloration, dehydration and spoilage can be controlled with proper use of the equipment and handling of product. Product temperature should always be maintained at a constant and proper temperature. This means that from the time the product is received, through storage, preparation and display, the temperature of the product must be controlled to maximize life of the product. Hussmann cases were not designed to “heat up” or “cool down” product - but rather to maintain an item’s proper temperature for maximum shelf life. To achieve the protection required always:

1. Minimize processing time to avoid damaging temperature rise to the product. Product should be at proper temperature.

2. Keep the air in and around the case area free of foreign gasses and fumes or food will rapidly deteriorate.

3. Maintain the display merchandisers temperature controls as outlined in the refrigerator section of this manual.

4. Do not place any product into these refrigerators until all controls have been adjusted and they are operating at the proper temperature. Allow merchandiser to operate a minimum of 6 hours before stocking with any product.

5. When stocking, never allow the product to extend beyond the recommended load limit. Air discharge and return air flow must be unobstructed at all times to provide proper refrigeration.

6. There are vents located at the base of the front of the glass, just above the front rail. These vents supply a continuous, gentle flow of air across the front glass which inhibits condensation. Do not place any signs or other restrictive objects on the front of the refrigerator that will block these vents.

7. Keep the service doors closed (when applicable). Refrigeration performance will be seriously affected if left open for a prolonged period of time.

8. Avoid the use of supplemental flood or spot lighting. Display light intensity has been designed for maximum visibility and product life at the factory. The use of higher output fluorescent lamps (H.O. and V.H.O.), will shorten the shelf life of the product.

9. In the Deli, Meat and Fish cases, completely cover the product each night with a clean damp cloth or butcher paper (never use plastic, as it does not allow for proper circulation). Make sure the cloth or paper is in direct contact with the product.

10. Turn and rotate the meat fairly often. The blood which gives the pink color works its way downward with time.

11. Cold coils remove heat and moisture from the case and deposit this as frost onto the coil. Thus, a defrost is required. Our humidity system induces moisture into the case and helps slow down the dehydration process. The only other moisture within the case is that in the product itself. A single level of meat will dry out faster than a fully loaded case of 3-4 levels of meat.

Important Steps1. Do not set temperature too cold, as this causes

product dehydration. Product Temperature: 33°F-35F°!

Set thermostat to cut in at 28°F discharge air. Meat holding box: 32°F. Meat prep room: 55°F. Meat bloom box: 36°F.

Process the meat to enter case at 40°F or below. Product deterioration is very rapid above 400.

2. Temperature control should be by means of a T-STAT and Suction Stop Solenoid at each case. Do not use EPR valves, Liquid Line Solenoids or electronic control devices of any kind, as these allow temperature swings causing dehydration and excessive energy consumption.

3. Product should be worked and rotated on a regular basis, not to exceed a 4-hour period.

25

4. At night, turn off case lights and cover the product with a damp (not wet) cloth similar to cheese cloth (etc.).This should be washed out in the morning and kept in a walk-in box during the day - so that it is cool and moist when covering the product.

5. Discharge air temperature should be approximately 26°F, with between 150-200 FPM air velocity. Do not display product directly within the air discharge.

6. Clean Humidity system a minimum of every 90 days for proper system operation.

Case CleaningLong life and satisfactory performance of any equipment are dependent upon the care given to it.To insure long life, proper sanitation and minimum maintenance costs, the refrigerator should be thoroughly cleaned frequently. SHUT OFF FAN DURING CLEANING PROCESS. It can be unplugged within the case, or shut off case at the source.The interior bottom may be cleaned with any domestic soap or detergent based cleaners. Sanitizing solutions will not harm the interior bottom, however, these solutions should always be used according to the manufacturer’s directions. It is essential to establish and regulate cleaning procedures. This will minimize bacteria causing discoloration which leads to degraded product appearance and significantly shortening product shelf life.Soap and hot water are not enough to kill this bacteria. A sanitizing solution must be included with each cleaning process to eliminate this bacteria.

1. Scrub thoroughly, cleaning all surfaces, with soap and hot water.

2. Rinse with hot water, but do not flood.3. Apply the sanitizing solution according to the

manufacturer’s directions.4. Rinse thoroughly.5. Dry completely before resuming operation.

Cleaning Glass and MirrorsOnly use a soft cloth and mild glass cleaner for cleaning any glass or mirrored components. Be sure to rinse and! or dry completely.Never use hot water on cold glass surfaces! It may shatter and cause serious injury! Allow glass surfaces to warm first.

Shut off fan during cleaningIF BY ANY REASON THE CUSTOMER MUST STORE THE CASE OTHER THAN ITS UPRIGHT POSITION. PLEASE ALLOW 2 HOURS MINIMUM PRIOR TO POWERING THE MERCHANDISER.

CLEANING PRECAUTIONS When cleaning: • Do not use high pressure water hoses • Do not introduce water faster then waste outlet can drain • NEVER INTRODUCE WATER ON SELF CONTAINED UNIT

WITH AN EVPORATOR PAN • NEVER USE A CLEANING OR SANITIZING SOLUTION

THAT HAS AN OIL BASE (these will dissolve the butyl sealants) or an AMMONA BASE (this will corrode the copper components of the case)

• TO PRESERVE THE ATTRACTIVE FINISH: • DO USE WATER AND A MILD DETERGENT FOR THE

EXTERIOR ONLY • DO NOT USE A CHLORANITED CLAENER ON ANY

SURFACE • DO NOT USE ABRASIVES OR STEEL WOOL SCOURING

PADS (these will mar the finish)

CAUTION

Plexiglass and Acrylic CareCleaningClean with plenty of nonabrasive soap (or detergent) and luke warm water, using the bare hand to feel and dislodge any caked-on dirt. A soft, grit-free cloth, sponge or chamois may be used, but only as a means of carrying the water to the plastic. Dry with a clean damp chamois or clean soft cloth such as cotton flannel. Hard, rough cloths or paper towels will scratch the acrylic and should not be used.NOTE: The base channel insert must slide out in order to be

cleaned. A hose can be used for cleaning purposes of this base insert channel only when no end panel is provided on the case.

WaxingIf after removing dirt and grease, the acrylic can be waxed with a good grade commercial wax. This will improve the appearance of the surface by filling in most minor scratches. Wax should be applied in a thin even coat and brought to a high polish by rubbing lightly with a dry clean soft cloth, such as a cotton flannel. Excessive rubbing may cause scratching and/or buildup an electrostatic charge which attracts dust and dirt to the surface. Blotting with a clean damp cloth is recommended to remove charge.

Antistatic CoatingsFor acrylic used indoors, antistatic coatings successfully prevent the accumulation of an electrostatic charge for periods of several months - if the surface is not washed or wiped down with a wet cloth. Between applications of the antistatic coatings, the parts need only be dusted with a soft clean cloth to maintain a good appearance. In use, liquid antistatic coatings should be applied in a very thin even coat. If beads appear as it is applied, the coat is too thick and the excess should be removed with another cloth. Allow the coating to dry, then bring to a high gloss with a soft cloth.

10. Maintenance

BEFORE SERVICINGALWAYS DISCONNECT ELECTRICAL

POWER AT THE MAIN DISCONNECTWHEN SERVICING OR REPLACING ANY

ELECTRICAL COMPONENT.This includes (but not limited to) Fans, Heaters

Thermostats, and Lights.

Evaporator FansThe evaporator fans are located at the center front of these merchandisers directly beneath the display pans. Should fans or blades need servicing, always replace fan blades with the raised embossed side of the blade TOWARD THE MOTOR.

Copper CoilsThe copper coils used in Hussmann merchandisers may be repaired in the field. Materials are available from local refrigeration wholesalers.Hussmann recommends using #15 Sil-Fos for repairs.

Tips and TroubleshootingBefore calling for service, check the following:

1. Check electrical power supply to the equipment for connection.

2. Check fixture loading. Overstocking case will affect its proper operation.

3. If frost is collecting on fixture and/or product, check that Humidity Control is working properly, and that no outside doors or windows are open - allowing moisture to enter store.

FOR PROMPT SERVICEWhen contacting the factory,

be sure to have the Case Model and SerialNumber handy. This information is on a plate

located on the case itself.

Stainless Steel Cleaning and CareThere are three basic things, which can break down your stainless steel’s passivity layer and allow corrosion.

1. Mechanical Abrasion Mechanical Abrasion means those things that

will scratch the steels surface. Steel Pads, wire Brushes, and Scrapers are prime examples.

2. Water Water comes out of our tap in varying degrees of

hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots. Also, when heated, hard water leaves deposits behind that if left to sit, will break down the passive layer and rust your stainless steel. Other deposits from food preparation and service must be properly removed.

3. Chlorides Chlorides are found nearly everywhere. They

are in water, food and table salt. One of the worst perpetrators of chlorides can come from household and industrial cleaners.

Don’t Despair! Here are a few steps that can help prevent stainless steel rust.

1. Use the Proper Tools When cleaning your stainless steel products, take

care to use non-abrasive tools. Soft Clothes and plastic scouring pads will NOT harm the steel’s passive layer. Stainless steel pads can also be used but the scrubbing motion must be in the same direction of the manufacturer’s polishing marks.

2. Clean With the Polish Lines Some stainless steels come with visible polishing

lines or “grain”. When visible lines are present, you should ALWAYS scrub in a motion that is parallel to them. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.

3. Use Alkaline, Alkaline Chlorinated or Non-chloride Containing Cleaners

While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask for an alternative. Also, avoid cleaners containing quaternary salts as they also can attack stainless steel & cause pitting and rusting.

4. Treat your Water Though this is not always practical, softening hard

water can do much to reduce deposits. There are certain filters that can be installed to remove distasteful and corrosive elements. Salts in a properly maintained water softener are your friends. If you are not sure of the proper water treatment, call a treatment specialist.

5. Keep your Food Equipment Clean Use alkaline, alkaline chlorinated or non-chlorinated

cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in your stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides has a similar effect.

6. RINSE, RINSE, RINSE If chlorinated cleaners are used you must rinse,

rinse, rinse and wipe dry immediately. The sooner you wipe off standing water, especially when sit contains cleaning agents, the better. After wiping the equipment down, allow it to air dry for the oxygen helps maintain the stainless steel’s passivity film.

7. Never Use Hydrochloric Acid (Muriatic Acid) on Stainless Steel

8. Regularly Restore/Passivate Stainless Steel

AppendicesAppendix A. - Temperature GuidelinesThe refrigerators should be operated according to the manufacturer’s published engineering specifications for entering air temperatures for specific equipment applications. Table 1 shows the typical temperature of the air entering the food zone one hour before the start of defrost and one hour after defrost for various categories of refrigerators. Refer to Appendix C for Field Evaluation Guidelines.

Table 1Type of Refrigerator Typical Entering

Appendix B. - Application Recommendations1.0 Temperature performance is critical for controlling

bacteria growth. Therefore, the following recommendations are included in the standard. They are based on confirmed field experience over many years.

1.1 The installer is responsible for following the installation instructions and recommendations provided by Hussmann for the installation

of each individual type refrigerator.1.2 Refrigeration piping should be sized according to

the equipment manufacturer’s recommendations

and installed in accordance with normal refrigeration practices. Refrigeration piping should be insulated according to Hussmann’s recommendations.

1.3 A clogged waste outlet blocks refrigeration. The installer is responsible for the proper installation of the system which dispenses condensate waste through an air gap into the building indirect waste system.

1.4 The installer should perform a complete start-up evaluation prior to the loading of food into the refrigerator, which includes such items as: a) Initial temperature performance, Coils should

be properly fed with a refrigerant according to manufacturer’s recommendations.

b) Observation of outside influences such as drafts, radiant heating from the ceiling and from lamps. Such influence should be properly corrected or compensated for.

c) At the same time, checks should be made of the store dry-bulb and wet-bulb temperatures to ascertain that they are within the limits prescribed by Hussmann.

d) Complete start-up procedures should include checking through a defrost to make certain of its adequate frequency and length without substantially exceeding the actual needs. This should include checking the electrical or refrigerant circuits to make sure that defrosts are correctly programmed for all the refrigerators connected to each refrigeration system.

e) Recording instruments should be used to check performance.

Appendix C. - Field RecommendationsRecommendations for field evaluating the performance of retail food refrigerators and hot cases1.0 The most consistent indicator of display

refrigerator performance is temperature of the air entering the product zone (see Appendix A). In practical use, the precise determination of return air temperature is extremely difficult. Readings of return air temperatures will be variable and results will be inconsistent. The product temperature alone is not an indicator of refrigerator performance.

55

Appendices (Cont'd)NOTE: Public Health will use the temperature of the product in

determining if the refrigerator will be allowed to display potentially hazardous food. For the purpose of this evaluation, product temperature above the FDA Food Code 1993 temperature for potentially hazardous food will be the first indication that an evaluation should be performed. It is expected that all refrigerators will keep food at the FDA Food Code 1993 temperature for potentially hazardous food.

1.1 The following recommendations are made for the purpose of arriving at easily taken and understood data which, coupled with other observations, may be used to determine whether a display refrigerator is working as intended:a) INSTRUMENT - A stainless steel stem-type

thermometer is recommended and it should have a dial a minimum of 1 inch internal diameter. A test thermometer scaled only in Celsius or dually scaled in Celsius and Fahrenheit shall be accurate to 1°C (1.8°F). Temperature measuring devices that are scaled only in Fahrenheit shall be accurate to 2°F. The thermometer should be checked for proper calibration. (It should read 32°F when the stem is immersed in an ice water bath).

b) LOCATION - The probe or sensing element of the thermometer should be located in the airstream where the air first enters the display or storage area, and not more than 1 inch away from the surface and in the center of the discharge opening.

c) READING - It should first be determined that the refrigerator is refrigerating and has operated at least one hour since the end of the last defrost period. The thermometer reading should be made only after it has been allowed to stabilize, i.e., maintain a constant reading.

d) OTHER OBSERVATIONS - Other observations should be made which may indicate operating problems, such as unsatisfactory product, feel/appearance.

e) CONCLUSIONS - In the absence of any apparent undesirable conditions, the refrigerator should be judged to be operating properly. If it is determined that such condition is undesirable, i.e., the product is above proper temperature, checks should be made for the following:1. Has the refrigerator been loaded with

warm product?2. Is the product loaded beyond the “Safe

Load Line” markers?

3. Are the return air ducts blocked?4. Are the entering air ducts blocked?5. Is a dumped display causing turbulent air

flow and mixing with room air?6. Are spotlights or other high intensity

lighting directed onto the product?7. Are there unusual draft conditions (from

heating/air-conditioning ducts, open doors, etc.)?

8. Is there exposure to direct sunlight?9. Are display signs blocking or diverting

airflow?10. Are the coils of the refrigerator iced up?11. Is the store ambient over 75°F, 55% RH

as set forth in ASHRAE Standard 72 and ASHRAE Standard 117?

12. Are the shelf positions, number, and size other than recommended by Hussmann?

13. Is there an improper application or control system?

14. Is the evaporator fan motor/blade inoperative?

15. Is the defrost time excessive?16. Is the defrost termination, thermostat (if

used) set too high?17. Are the refrigerant controls incorrectly

adjusted?18. Is the air entering the condenser above

design conditions? Are the condenser fins clear of dirt, dust, etc.?

19. Is there a shortage of refrigerant?20. Has the equipment been modified

to use replacements for CFC-12, CFC-502 or other refrigerant? If so, have the modifications been made in accordance with the recommendations of the equipment manufacturer? Is the refrigerator charged with the proper refrigerant and lubricant? Does the system use the recommended compressor?

Appendix D. - Recommendations to User1.0 Hussmann Corporation provides instructions

and recommendations for proper periodic cleaning. The user will be responsible for such cleaning, including the cleaning of low temperature equipment within the compartment and the cooling coil area(s). Cleaning practices, particularly with respect to proper refrigerator unloading and warm-up, must be in accordance with applicable recommendations.

56

Appendices (Cont'd)1.1 Cleaning of non frozen food equipment

should include a weekly cleaning of the food compartment as a minimum to prevent bacteria growth from accumulating. Actual use and products may dictate more frequent cleaning. Circumstances of use and equipment design must also dictate the frequency of cleaning the display areas. Weekly washing down of the storage compartment is also recommended, especially for equipment subject to drippage of milk or other liquids, or the collection of vegetable, meat, crumbs, etc. or other debris or litter. Daily cleaning of the external areas surrounding the storage or display compartments with detergent and water will keep the equipment presentable and prevent grime buildup.

1.2 Load levels as defined by the manufacturer must be observed.

1.3 The best preservation is achieved by following these rules:a) Buy quality products.b) Receive perishables from transit equipment

at the ideal temperature for the particular product.

c) Expedite perishables to the store’s storage equipment to avoid unnecessary warm-up and prolonged temperature recovery. Food store refrigerators are not food chillers nor can they reclaim quality lost through previous mishandling.

d) Care must be taken when cross merchandising products to ensure that potentially hazardous vegetable products are not placed in non refrigerated areas.

e) Display and storage equipment doors should be kept closed during periods of inactivity.

f) Minimize the transfer time of perishables from storage to display.

g) Keep meat under refrigeration in meat cutting and processing area except for the few moments it is being handled in processing. When a cut or tray of meat is not to be worked on immediately, the procedure should call for returning it to refrigeration.

h) Keep tools clean and sanitized. Since mechanical equipment is used for fresh meat processing, all such equipment should be cleaned at least daily and each time a different kind of meat product comes in contact with the tool or equipment.

i) Make sure that all refrigeration equipment is installed and adjusted in strict accordance with the manufacturer’s recommendations.

j) See that all storage and refrigeration equipment is kept in proper working order by routine maintenance.

Operation

SensorsUp to two thermostat sensors can be connected to the controller. The relevant application determines how.

A sensor in the air before the evaporator:This connection is primarily used when control is based on area.

A sensor in the air after the evaporator:This connection is primarily used when refrigeration is controlled and there is a risk of a too low temperature near the products.

A sensor before and after the evaporator:This connection offers you the possibility of adapting the thermostat, the alarm thermostat and the display to the relevant application. The signal to the thermostat, the alarm thermostat and the display is set as a weighted value between the two temperatures, and 50% will for example give the same value from both sensors.The signal to the thermostat, the alarm thermostat and the display can be set independently of one another.

Defrost sensorThe best signal concerning the evaporator’s temperature is obtained from a defrost sensor mounted directly on the evaporator. Here the signal may be used by the defrost function, so that the shortest and most energy-saving defrost can take place.

If a defrost sensor is not required, defrost can be stopped based on time, or S4 can be selected.

Control of two compressorsThis control is used for controlling two compressors of the same size. The principle for control is that one of the compressors connects at ½ the differential of the thermostat, and the other at the full differential. When the thermostat cuts in the compressor with the fewest operating hours is started. The other compressor will only start after a set time delay, so that the load will be divided between them. The time delay has a higher priority than the temperature.When the air temperature has dropped by half the differential the one compressor will stop, the other will continue working and not stop until the required temperature is achieved.The compressors used must be of a type that is capable of starting up against a high pressure.

Change of temperature referenceIn an impulse appliance, for example, used for various product groups. Here the temperature reference is changed easily with a contact signal on a digital input. The signal raises the normal thermostat value by a predefined amount. At the same time the alarm limits with the same value are displaced accordingly.

Operation

SensorsUp to two thermostat sensors can be connected to the controller. The relevant application determines how.

A sensor in the air before the evaporator:This connection is primarily used when control is based on area.

A sensor in the air after the evaporator:This connection is primarily used when refrigeration is controlled and there is a risk of a too low temperature near the products.

A sensor before and after the evaporator:This connection offers you the possibility of adapting the thermostat, the alarm thermostat and the display to the relevant application. The signal to the thermostat, the alarm thermostat and the display is set as a weighted value between the two temperatures, and 50% will for example give the same value from both sensors.The signal to the thermostat, the alarm thermostat and the display can be set independently of one another.

Defrost sensorThe best signal concerning the evaporator’s temperature is obtained from a defrost sensor mounted directly on the evaporator. Here the signal may be used by the defrost function, so that the shortest and most energy-saving defrost can take place.

If a defrost sensor is not required, defrost can be stopped based on time, or S4 can be selected.

Control of two compressorsThis control is used for controlling two compressors of the same size. The principle for control is that one of the compressors connects at ½ the differential of the thermostat, and the other at the full differential. When the thermostat cuts in the compressor with the fewest operating hours is started. The other compressor will only start after a set time delay, so that the load will be divided between them. The time delay has a higher priority than the temperature.When the air temperature has dropped by half the differential the one compressor will stop, the other will continue working and not stop until the required temperature is achieved.The compressors used must be of a type that is capable of starting up against a high pressure.

Change of temperature referenceIn an impulse appliance, for example, used for various product groups. Here the temperature reference is changed easily with a contact signal on a digital input. The signal raises the normal thermostat value by a predefined amount. At the same time the alarm limits with the same value are displaced accordingly.


Digital inputsThere are two digital inputs both of which can be used for the following functions:- Case cleaning- Door contact function with alarm- Starting a defrost- Coordinated defrost- Change-over between two temperature reference- Retransmission of a contact’s position via data communication

Case cleaning functionThis function makes it easy to steer the refrigeration appliance through a cleaning phase. Via three pushes on a switch you change from one phase to the next phase.The first push stops the refrigeration – the fans keep working”Later”: The next push stops the fans”Still later”: The next push restarts refrigerationThe different situations can be followed on the display.

On the network a cleaning alarm is transmitted to the system unit. This alarm can be ”logged” so that proof of the sequence of events is provided.

Door contact functionIn cold rooms and frost rooms the door switch can switch the light on and off, start and stop the refrigeration and give alarm if the door has remained open for too long.

DefrostDepending on the application you may choose between the fol-lowing defrost methods:Natural: Here the fans are kept operating during the defrostElectric: The heating element is activatedBrine: The valve is kept open so that the brine can flow through the evaporatorHotgas: Here the solenoid valves are controlled so that the hotgas can flow through the evaporator

Start of defrostA defrost can be started in different waysInterval: Defrost is started at fixed time intervals, say, every eighth hourRefrigeration time: Defrost is started at fixed refrigeration time intervals, in other words, a low need for refrigeration will ”postpone” the coming defrostSchedule: Here defrost can be started at fixed times of the day and night. However, max. 6 timesContact: Defrost is started with a contact signal on a digital inputNetwork: The signal for defrost is received from a system unit via the data communicationS5 temp In 1:1 systems the efficiency of the evaporator can

be followed. Icing-up will start a defrost.Manual: An extra defrost can be activated from the control-

ler’s lower-most button. (Though not for application 4).

All the mentioned methods can be used at random – if just one them is activated a defrost will be started.

Hot gas application


Extra module

• The controller can afterwards be fitted with an insertion module if the application requires it.The controller has been prepared with plug, so the module simply has to be pushed in

- Battery moduleThe module guarantees voltage to the controller if the supply voltage should drop out for more than four hours. The clock function can thus be protected during a power failure.

- Data communicationIf you require operation from a PC, a data communication mod-ule has to be placed in the controller.

• External displayIf it is necessary to indicate the temperature on the front of re-frigeration appliance, a display type EKA 163A can be mounted. The extra display will show the same information as the control-ler's display, but does not incorporate buttons for operation. If operation from the external display is needed a display type EKA 164A must be mounted.

Coordinated defrost

There are two ways in which coordinated defrost can be arranged. Either with wire connections between the controllers or via data communication

Wire connectionsOne of the controllers is defined to be the controlling unit and a battery module may be fitted in it so that the clock is ensured backup. When a defrost is started all the other controllers will follow suit and likewise start a defrost. After the defrost the indi-vidual controllers will move into waiting position. When all are in waiting position there will be a change-over to refrigeration.(If just one in the group demands defrost, the others will follow suit).

Defrost via data communicationAll controllers are fitted with a data communication module, and via the override function from a gateway the defrost can be coordinated.

Defrost on demand1 Based on refrigeration time

When the aggregate refrigeration time has passed a fixed time, a defrost will be started.

2 Based on temperatureThe controller will constantly follow the temperature at S5. Between two defrosts the S5 temperature will become lower the more the evaporator ices up (the compressor operates for a longer time and pulls the S5 temperature further down). When the temperature passes a set allowed variation the defrost will be started.This function can only work in 1:1 systems

ApplicationsHere is a survey of the controller’s field of application.

A setting will define the relay outputs so that the controller’s interface will be targeted to the chosen application.

On page 20 you can see the relevant settings for the respective wiring diagrams.

Refrigeration control with one compressorThe functions are adapted to small refrigeration systems which either may be refrigeration appliances or cold rooms.The three relays can control the refrigeration, the defrost and the fans, and the fourth relay can be used for either alarm function, light control or rail heat control• The alarm function can be linked up with a contact function

from a door switch. If the door remains open longer than al-lowed there will be an alarm.

• The light control can also be linked up with a contact function from a door switch. An open door will switch on the light and it will remain lit for two minutes after the door has been closed again.

• The rail heat function can be used in refrigeration or freezing appliances or on the door’s heating element for frost rooms.

The fans can be stopped during defrost and they may also follow a door switch’s open/close situation.

There are several other functions for the alarm function as well as the light control, rail heat control and fans. Please refer to the respective settings.

Hot gas defrostThis type of connection can be used on systems with hotgas defrost, but only in small systems in, say, supermarkets – the functional content has not been adapted to systems with large charges. Relay 1’s change-over function can be used by the bypass valve and/or the hotgas valve.Relay 2 is used for refrigeration.

S3 and S4 are temperature sensors. The application will deter-mine whether either one or the other or both sensors are to be used. S3 is placed in the air flow before the evaporator. S4 after the evaporator.A percentage setting will determine according to what the control is to be based. S5 is a defrost sensor and is placed on the evaporator.DI1 and DI2 are contact functions that can be used for one of the following functions: door function, alarm function, defrost start, external main switch, night operation, change of thermostat ref-erence, appliance cleaning, forced refrigeration or coordinated defrost. See the functions in settings o02 and o37.


Refrigeration control with two compressors This group of applications can be used if the controller is to cut two compressors in and out.The functions can be compared with wiring diagrams 1 to 3, but instead of controlling fans the relay is here used for compressor 2.

The two compressors must be of the same size. When the controller demands refrigeration it will first cut in the compres-sor with the shortest operating time. After the time delay the second compressor will be cut in.

When the temperature has dropped to ”the middle of the dif-ferential”, the compressor with the longest operation time will be cut out.If the running compressor does not manage to reduce the tem-perature to the cutout point, the other compressor will be cut in again. This happens when the temperature reaches the top part of the differential. If the temperature is instead ”stuck” in the dif-ferential for two hours, there will be a change-over between the two compressors so that the operating time can be equalised.The two compressors must be of a type that can start up against a high pressure.

The compressors’s settings for ”Min On time” and ”Min Off time” will always have top priority during normal regulation. But if one of the override functions is activated, the ”Min On time” will be disregarded.

If the controller is to cut 2 compressor and 1 fan in and out, relay 4 must cut the fan in and out.This function is activated in application 10.

Simple refrigeration with defrost This application can be used where there is only regulation of refrigeration and defrost.

Heating functionThis application is the same as under 1, but a heating function has been added which protects the unit against too low tem-perature. The defrost function’s heating element is here used for heating.

This application is used where the temperature can go below the set cutout temperature for the refrigeration. To ensure that the temperature will not become too low the heating element is activated x degrees below the reference value.The S3 sensor must be mounted. It supplies the signal when there is heating.

Heating functionThe function uses the defrost function’s heating element for raising the temperature. The function enters into force a number of degrees (r36) below the actual reference and cuts out again with a differential of 2 degrees. Regulation is carried out with 100% signal from the S3 sensor. The fans will be operating when there is heating. The fans and the heating function will stop if door function has been selected and the door is opened. Where this function is used an external safety cutout should also be installed, so that superheating of the heating element cannot take place.Remember to set D01 to electrical defrosting.

Alarm Alarm settings

The controller can give alarm in different situations. When there is an alarm all the light-emitting diodes (LED) will flash on the controller front panel, and the alarm relay will cut in.

With data communication the impor-tance of the individual alarms can be defined. Setting is carried out in the “Alarm destinations” menu.

Alarm delay (short alarm delay)If one of the two limit values is exceeded, a timer function will commence. The alarm will not become active until the set time delay has been passed. The time delay is set in minutes.

A03 Alarm delay

Time delay for door alarmThe time delay is set in minutes.The function is defined in o02 or in o37.

Upper alarm limitHere you set when the alarm for high temperature is to start. The limit value is set in °C (absolute value). The limit value will be raised during night operation. The value is the same as the one set for night setback, but will only be raised if the value is posi-tive.The limit value will also be raised in connection with reference displacement r39.

Compressor Compressor controlThe compressor relay works in conjunction with the thermostat. When the thermo-stat calls for refrigeration will the compressor relay be operated.

Running timesTo prevent irregular operation, values can be set for the time the compressor is to run once it has been started. And for how long it at least has to be stopped.The running times are not observed when defrosts start.

The LED on the controller’s front will show whether refrigeration is in progress. Comp RelayHere you can read the status of the compressor relay, or you can force-control the relay in the ”Manual control” mode

Defrost Defrost controlThe controller contains a timer function that is zeroset after each defrost start.The timer function will start a defrost if/when the interval time is passed.The timer function starts when voltage is connected to the controller, but it is dis-placed the first time by the setting in d05.If there is power failure the timer value will be saved and continue from here when the power returns.This timer function can be used as a simple way of starting defrosts, but it will always act as safety defrost if one of the subsequent defrost starts is not received.The controller also contains a real-time clock. By means of settings of this clock and times for the required defrost times, defrost can be started at fixed times of the day. If there is a risk of power failure for periods longer than four hours, a battery module should be mounted in the controller.Defrost start can also be accomplished via data communication, via contact signals or manual start-up.All starting methods will function in the controller. The different functions have to be set, so that defrosts do not ”come tumbling” one after the other.Defrost can be accomplished with electricity, hotgas or brine.The actual defrost will be stopped based on time or temperature with a signal from a temperature sensor.Defrost methodHere you set whether defrost is to be accomplished with electricity, gas, brine or "non". During defrost the defrost relay will be cut in.(With brine the ”refrigeration control valve” will be kept open during defrost)

Interval between defrost startsThe function is zero set and will start the timer function at each defrost start. When the time has expired the function will start a defrost.The function is used as a simple defrost start, or it may be used as a safeguard if the normal signal fails to appear.If master/slave defrost without clock function or without data communication is used, the interval time will be used as max. time between defrosts.If a defrost start via data communication does not take place, the interval time will be used as max. time between defrosts.When there is defrost with clock function or data communication, the interval time must be set for a somewhat longer period of time than the planned one, as the interval time will otherwise start a defrost which a little later will be followed by the planned one.In connection with power failure the interval time will be maintained, and when the power returns the interval time will continue from the maintained value.The interval time is not active when set to 0.

This view will con-tinue up till 15 min. after the cooling has resumed.However the view of –d- will be discontinued if:- The temperature is suitable within the 15 minutes- The regulation is stopped with “Main Switch”- A high temperature alarm appears

The buttonsWhen you want to change a setting, the upper and the lower buttons will give you a higher or lower value depending on the button you are pushing. But before you change the value, you must have access to the menu. You obtain this by pushing the upper button for a couple of seconds - you will then enter the col-umn with parameter codes. Find the parameter code you want to change and push the middle buttons until value for the parameter is shown. When you have changed the value, save the new value by once more pushing the middle button.

Examples

Set menu1. Push the upper button until a parameter r01 is shown2. Push the upper or the lower button and find that parameter you

want to change3. Push the middle button until the parameter value is shown4. Push the upper or the lower button and select the new value5. Push the middle button again to freeze the value.

Cutout alarm relay / receipt alarm/see alarm code • Push short the upper button

If there are several alarm codes they are found in a rolling stack. Push the uppermost or lowermost button to scan the rolling stack.

DisplayThe values will be shown with three digits, and with a setting you can determine whether the temperature are to be shown in °C or in °F.

Operation

Get a good start

With the following procedure you can start regulation very quick-ly:

1 Open parameter r12 and stop the regulation (in a new and not previously set unit, r12 will already be set to 0 which means stopped regulation.)

2 Select electric connection based on the drawings on page 6

3 Open parameter o61 and set the electric connection number in it

4 Now select one of the preset settings from the table on page 22.

5 Open parameter o62 and set the number for the array of preset-tings. The few selected settings will now be transferred to the menu.

6 Open parameter r12 and start the regulation

7 Go through the survey of factory settings. The values in the grey cells are changed according to your choice of settings. Make any necessary changes in the respective parameters.

8 For network. Set the address in o03 and then transmit it to the gateway/system unit with setting o04.

Set temperature1. Push the middle button until the temperature value is shown2. Push the upper or the lower button and select the new value3. Push the middle button again to conclude the setting.

(Though not for application 4).

See HACCP registration1. Give the middle button a long push until h01 appears2. Select required h01-h103. See value by giving the middle button a short push


HACCPThis function will follow the appliance temperature and sound an alarm if the set temperature limit is exceeded. The alarm will come when the time delay has elapsed.When the temperature exceeds the limit value it will continuously be registered and the peak value will be saved until the later rea-dout. Saved together with the value will be the time and duration of the temperature exceeding.

Examples of temperature exceeding:

Exceeding during normal regulation

Exceeding in connection with power failure where the controller can keep on registering the time performance.

Exceeding in connection with power failure when the controller has lost its clock function and hence also its time performance.

The readout of the various values in the HACCP function can take place with a long push on the middle button.The readouts are, as follows:h01: The temperatureh02: Readout of the controller’s status when temperature was exceeded: H1 = normal regulation. H2 = power failure. Times are saved. H3 = power failure. Times not saved.h03: Time. Yearh04: Time. Monthh05: Time: Dayh06: Time. Hourh07: Time.
