HOW TO USE THIS MANUALRead and save these instructions. This manual is designed to assist qualified field service, operatingand maintenance personnel with the installation, operation, and maintenance of Greenheck canopytype kitchen hoods.

Procedures described in this manual should be followed in the order they appear, with attention to allsafety and caution statements.

RECEIVING AND HANDLINGUpon receiving the equipment, check for both obvious and hidden damage. If damage is found,record all necessary information on the bill of lading and file a claim with the final carrier. Check alsoto be sure that all parts of the shipment, including accessories, are accounted for.

STORAGEIf a kitchen hood must be stored prior to installation, (or for any long period) it must be protected fromdirt and moisture. Indoor storage is recommended. For outdoor storage, cover the hood with a tarp tokeep it clean, dry, and protected from UV (Ultra Violet Radiation) damage.

Improper storage which results in damage to the unit will void the warranty.

INSTALLATION

NOTE: If you have a BackSupply Plenum (BSP), thismust be installed before thehood. Please see Page 11.

For Wall/Single Island StyleHoods, prior to installation,check with local authoritieshaving jurisdiction onclearances to combustiblesurfaces, etc.

With the hood still inside itspacking crate, position the unit

beneath its installation location. Carefully remove the packing crate. Place some protective materialon the floor next to the crate to avoid damaging the hood as it is tipped on its side. (See Fig. 1) Tip thehood carefully onto the protective material. If you have filler panels, install them now. Please see Page 13. If you have integral filler panels, no additional installation is needed.

Insert 1⁄2 in. diameter threaded rod (by others) into hanger brackets on hood top. (Fig. 2, Pg. 7) Checkthe engineering drawings for proper hood height above finished floor. Greenheck recommends thatthe hoods be hung 6 feet 6 inches above the finished floor. Raise and hang hood from adequate roofor ceiling supports. All hanger brackets must be used and hood must be properly supported whilelifting to prevent damage or distortion to the hood. The hood must be hung level to operate properly.The grease trough is pitched to drain into the grease container.

This is a guide to assist in determining if multiple hoods on one fan can be balanced to have equalstatic pressure. For multiple hoods on one fan to achieve their designed exhaust flow, all of the hoodsmust have equal static pressure at their designed exhaust flow.

The laws of physics force the static pressure for each branch of a duct system on one fan to always beequal. This will happen by the flow rate increasing in low static branches and decreasing in high staticbranches until the static pressure is equal in all branches.

Checking for Balance

Every hood with an EABB has a range for its static pressure. The low number in this range is given bythe standard calculation for hood static. (Static that is printed with the CAPS submittal). The maximumincrease above the low number can be calculated from the duct velocity at the low static, (also givenon CAPS submittal). This is then added to the low number to get the highest static pressure possiblewith an EABB.

The maximum potential increase in static is given in the graph, or can be calculated from:

Max. Increase = 0.00000036 x (Duct velocity)2

After the range for each hood is calculated, itshould be compared to the hood with the higheststatic pressure. If the highest hood falls inside ofthe range, then the hoods can be balanced withthe EABB. If it is higher than the range, the hoodscannot be balanced.

Example 1:

Hood 1: Ps = 0.58 inH2O

Duct Velocity = 1900 FPM



Hood 2 has the lower Ps, at 1800 FPM the maximum increase in Ps is 1.17. The range for hood 2 is0.44 to 1.61. Hood 1 is less than 1.61 so these hoods can be balanced.

Example 2:





Hood 4 has the lower Ps, at 1500 FPM the maximum increase in Ps is .81. The range for hood 4 is 0.44to 1.25. Hood 3 is higher than 1.25 so these hoods cannot be balanced.

Note 1: For many systems, an EABB may not be needed on the hood that has the highest static pressure. Theexception to this is if the individual ductwork has uneven static pressures.

Note 2: When sizing the fan, use the static pressure from the highest hood and sum the CFM from all the hoods.

TESTING HOOD AIR VOLUME

Baffle Filter Style Hoods

A. Exhaust:

With all the filters in place, determinethe total hood exhaust volume with arotating vane anemometer as follows:

1. All cooking equipment shouldbe on. Short circuit air supply (if any) should be off.

2. Measure the Velocities

Velocity measurements shouldbe taken at 5 locations perfilter. These must be over afilter slot as in Fig. 16.

BALANCING THE KITCHEN EXHAUST SYSTEM

A. To determine the proper dining room air balance:

1. Refer to engineering drawings to determine total exhaust CFM from dining areas. (Exhaust fans,heating and air conditioning units, restrooms, etc.)

2. Determine the total CFM of make-up air supplied to dining area.

3. Subtract #1 from #2 above. If the result is a negative number, a negative pressure is present inthe dining area. In this case, kitchen exhaust odors could be drawn from the kitchen to thedining area. Therefore, exhaust or supply air should be adjusted to provide a slight positivepressure in the dining area.

B. To determine proper kitchen air balance:

1. Refer to engineering drawings to determine total exhaust from the kitchen area. (Exhausthoods, dishwasher hoods, etc.)

2. Determine total CFM of make-up air supplied to kitchen area. (Make-up air hoods, heating andair conditioning units, etc.)

3. Subtract #1 from #2 above. The result should be a negative number. If the result is a positivenumber, a positive pressure is present in the kitchen area. Kitchen odors could be forced intothe dining area. Also, a positively balanced kitchen area can adversely affect the performanceof the exhaust hood.

Caution: According to NFPA 96, Ch. 8-3 Replacement Air : Replacement air quantity shall be adequateto prevent negative pressures in the commercial cooking areas from exceeding 4.98kPa (.02 in. watercolumn).

B. Supply (If Applicable):

Example for Perforated Face Supply

1. Hood set upIf the make-up air unit has a temperature control, it should be used to keep the supply air at the desired room discharge air temperature.

2. Measure VelocitiesDivide the perforated face panel into a grid of equal areas, each approximately 4 in. square.

Measure the velocity at the center of each grid area. A digital 2 3/4 in. rotating vaneanemometer or equivalent is suggested. The center of the anemometer should be held tight tothe face of the panel, and parallel to the filter. Both squareness and distance are important foraccuracy. Calculate the average velocity of the panel.

3. Measure the length, height, and width of the perforated face panel.

4. Calculate the perforated face panel volume in CFM by using the following formula:

Volume = Avg. Velocity * Length (in.) * Height (in.) * .005

5. Calculate the system’s volume by repeating the process for the remaining panels and addingthe individual panel volumes together.

Short Circuit HoodsA. Supply

All cooking equipment should be off. The hoodexhaust should also be off.


• Velocity measurements should be made witha digital 2-3/4 in. rotating vane anemometer or its equivalent.

• One velocity measurement should be taken for every 8 in. of short circuit opening length, starting tight against one edge of theopening, and finishing tight against the other edge. The anemometer should be placed at the bottom edge of the opening, flush with the bottom lip as shown in Fig. 31. Both squareness and placement are important for accuracy.

2. Calculate the average slot velocity.

3. Calculate the CFM per linear foot by dividing theaverage velocity by a conversion factor of 5.52.

4. Calculate the hoods exhaust volume by multiplying the CFM per linear foot by the total hood length.

Example: 4 ft. short circuit hood (36 in. short circuitopening).

1. Number of Readings = 36 in. / 8 in. => 6 readings

2. Average Slot Velocity = (Sum of Velocity Readings)(Number of Readings)

= 786 + 900 + 1126 + 1048 + 1111 + 1115 = 6086 = 1014 FPM6 6

3. CFM per Linear Foot = Average Slot Velocity in FPM = 1014 = 184 CFM / Linear Foot5.52 5.52

4. Hood Supply Volume = (CFM/Linear Foot) x (Total Hood Length in Feet)= 184 x 4 = 736 CFM

MAINTENANCE

Daily Maintenance1. Wipe grease from exposed metal surfaces on the hood interior using a clean, dry cloth.

2. Visually inspect the filters or cartridges for grease accumulation.

3. Remove grease cup, empty contents, and replace cup.

Weekly Maintenance1. Remove the grease filters or cartridges and wash in dishwasher or pot sink.

Note: Filters installed over heavy grease producing equipment may require more frequentcleaning. See filter cleaning schedule.

2. Before replacing filters, clean the interior plenum surfaces of any residual grease accumulations.

Periodic Maintenance1. Painted hood exterior surfaces should be cleaned with a mild detergent solution.

2. Stainless steel hood exterior surfaces should be cleaned with a mild detergent and then polished with a good grade stainless steel polish to preserve the original luster.

Note: Never use abrasive cleaners or chemicals on hood surfaces. Never use chlorine basedcleaners or iron wool pads to clean the hood. They may scratch or mar the material.Always rub with the grain of the stainless.

3. To maintain optimum performance of your hood and fan, duct cleaning should be performed asoften as the application and code requires.

4. Recaulk the hoods with an NSF approved silicone caulk, (GE SCS-1009 or it's equivalent) asneeded.

CONDENSATE HOOD BAFFLE INSTALLATION

1. Grasp the baffle with drain holes facingdown and lift into the hood. For shorthoods with only one baffle it may benecessary to turn the baffle slightlydiagonal to fit it past the drain channel.

2. After the baffle clears the drain channel ofthe hood, turn the baffle so it is lined upwith the upper hanger in the hood.

3. Hook the upper channel of the baffle overthe upper hanger of the hood and set thelower edge of the baffle into thecondensate gutter. Repeat until all bafflesare installed in the hood.

4. Center the baffle from side to side in thehood.

Grease Grabber™ Multi - Stage Filtration System

For use in Model GG__ Canopy Hoods Only

INSTALLATION

NOTE: Never install the Second Stage filter in the front filter channel. The Second Stagefilter must be installed behind a UL Classified Grease-X-Tractor™ primary filter Model HE orGX.

1. Slide the top edge of the Second Stage filter into the top rear filter channel. See Fig. 32.

2. Lifting the lower edge of the filter past the grease trough, continue to push the top of the filter into the channel.

3. When the filter is even with the bottom rear filter channel, set the filter into the channel. See Fig. 33.

4. Slide the filter to one end of the hood and repeat until all the filters are installed. Make sure the filters are placed tightly together with no visible gaps.

5. Latch filters together by connecting hooks to handle on next filter. See Fig. 34.

6. Install the Grease-X-Tractor™ primary filters in the same manner using the front filter channel.

Frequent Maintenance:

Required washing frequency is dependent on type of cooking and quantity of food cooked.

1. Remove filters from hood and place each filter in a whirlpool sink or dishwasher.

2. If using a whirlpool sink, cycle for 10 minutes. Use standard dish wash soap.

3. If using a dishwasher, cycle it 3 times to ensure all grease is removed.

Note: For hoods with large quantities of filters, it is acceptable to wash 3 to 4 filters each day,cycling all of the filters in 3 days

Note: The beads will discolor. Standard cooking will turn the beads yellow in color. Openflame cooking will cause the beads to blacken. Neither affects the performance of the filters.

Periodic Inspection:

1. Each filter may be soaked in hot soapy water for 2 hours once a month prior to washing if grease build-up is found.

2. Inspect the filters for grease build-up on the beads (visible through the perforated panel). If visible, repeat above. If grease build-up cannot be removed, replace filter.

3. Inspect the filters by holding it up to a light. Light shining through more than six holes in a group indicates filter damage. Replace the filter.
