3.2 General functional description The primary purpose of Chillers is to supply a cooled fluid (such as a water/glycol mixture) in order to absorb heat at source and transport it away. The fluid required for this purpose is supplied via a pipe-line system. In principle, the Chiller is comprised of four main parts (cf. Figure 9 and 10): - Evaporator coil (15), - Refrigerant compressor (1), - Condenser (5) with fans (10), - Expansion valve (20), which are connected to one another via pipelines. The high-pressure switch (70) limits the maximum pressure in the refrigerant cycle. The low-pressure switch (71) switches off the refrigerant cycle in the event of low pressure. Refrigerant R134a is free from chlorine. Its ozone destruction potential (ODP) is 0. A filter dryer (25) which is integrated into the hermetically sealed cooling circuit provides effective protection against moisture, acid, dirt particles, and foreign bodies within the cooling circuit. The tempe-rature control (80) ensures that the cooling medium is kept at the preset temperature. In the evaporator coil (15), the liquid refrigerant is transformed to a gaseous state. The heat required for this purpose is taken from the cooling medium in the plate heat exchanger, thereby cooling it. The refrigerant is compressed in the compressor (1), causing the refrigerant to achieve a higher temperature level than the ambient air. This heat is emitted to the ambient air via the surface of the condenser (5), causing the refrigerant to liquefy again. It is injected into the evaporator coil (15) via a thermostatic ex-

pansion valve (20), causing it to relax and subse-quently absorb the heat from the cooling medium (water-glycol mixture) in the evaporator coil. The cooling medium is conveyed in a closed circuit to the equipment via the pump (55) and cooling medium tank (10). Temperature monitoring of the evaporator coil (15) ensures protection against free-zing if the flowrate is insufficient. The inlet tempera-ture of the cooling medium (water-glycol mixture) is regulated via the controller (80). Flow diagrams for the individual unit types may be found in chapter 13

3.5 Safety equipment - The Chiller has a component-tested pressure

switch to EN 12263 in the refrigerant circuit, which is set to a cut-off pressure Pset ≤ PS.

- If there is a risk of icing, the evaporator coil is switched off and automatically switched on again at higher temperatures.

- The refrigerant compressor motor, fan motors and pump are equipped with thermal winding protection switches (RC elements) to protect them from excess current and excess tempera-tures.

- The Chiller also has a door contact switch to prevent activation while the door is open.

3.6 Filter mats (optionally available) In case of coarse dust, lint and/or oily ambient air, we recommend the use of an additional filter mat (see chapter 11). Depending on the ambient condi-tions, the filters will need to be replaced at regular intervals. By contrast, aluminium filter mats can be cleaned using suitable detergents and then reused.

3.7 Proper use The Chiller was developed and designed in ac-cordance with the latest state-of-the-art and the recognised rules governing technical safety. Never-theless, if used improperly, they may pose a threat to life and limb or cause damage to property. The Chillers described in this documentation are intended solely for cooling water-glycol mixtures. When using other fluids (such as deionised water), please observe the technical specifications in the Annex or contact the manufacturers. Under no cir-cumstances should the tolerances specified in the technical specifications be exceeded.

3.8 Scope of supply The unit is supplied in a packaging unit in a fully assembled state. Check the supply contents for completeness (see Table 3). Also, please check the packaging carefully for signs of damage. For exa-mple, traces of oil on damaged packaging could indicate a refrigerant leak.

Note: Any damage to the packaging may be the cause of subsequent malfunctions.

5.2 Installation site requirements - The Chiller must be adequately protected from

the influences of weather. - If the ambient air contains a high concentration

of dust or oily substances, the Chiller should be fitted with a metal filter (see chapter 11).

- The supporting surface should be flat and suffi-ciently robust to hold the weight (see rating pla-te) during operation.

- The ambient temperature must not be higher than +43°C or lower than +10°C (or -20°C with a winter controller, optionally available).

- In order to prevent performance losses caused by pressure drops in the pipework, the Chiller

(1) (1)

Fig. 20: Dimensions (supply connection) of rear excluding base/plinth (shown 3335.790)

EN should be sited as close as possible to the equipment.

- In order to make maintenance and repair work easier, the minimum distances shown under Fi-gure 21 should be adhered to.

- In order to avoid an "air short-circuit" (mixing of air intake and waste air) and ensure full cooling output, the minimum distances shown under Fi-gure 21 should be adhered to.

Side Minimum distance Reason

A (air outlet, top) 1000 mm Required distance from air outlet

B (air intake, rear) 800 mm Required distance from air outlet

C (front) 800 mm Minimum distance for maintenance

Fig. 21: Minimum distances - Ensure adequate ventilation of the room where

the Chiller is sited, so that the hot waste air do-es not heat up the room excessively.

Note: With a water-cooled condenser (optio-nally available), the distances shown under Figure 21 need not be observed

Caution! The connection of an air intake / waste air duct is inadmissible. These devices are equipped with axial fans and are incapable of developing the requisite pressure resistance.

5.3 Minimum volume of installation site The minimum volume of the installation site is calcu-lated from the ratio of refrigerant fill volume [kg] to the practical limit [kg/m³] of the refrigerant.

Note: The practical limit (PL) is a refrigerant-specific value. It indicates the maxi-mum permissible volume of refrigerant per m³ of space which could be relea-sed suddenly without injury to persons.

Example: The practical limit of refrigerant R410a is 0.44 kg/m³. The refrigerant fill volume of Chiller 3335.790 is 2.3 kg. The minimum volume of the installation site [m³] is therefore:

5.4 Siting the Chiller - Position the Chiller on a flat, stable surface. - Any deviations from the vertical must not

exceed a maximum of 2°. - A pressureless water tank is installed in the

Chiller. It must therefore be installed higher than the equipment. For installation at a lower height we recommend installing a non-return valve in the inlet and a magnetic valve in the return of the cooling medium circuit (optionally available) so as to avoid a potential tank overflow (see Fi-gure 22)

Fig. 22: Installation example with non-return and magnetic valve - Installing an overflow valve (optionally available,

see chapter 11) ensures that cooling water cir-culation is always maintained with the magnetic valves of the air/water heat exchangers closed and the Chiller pump running. This is achieved by opening the overflow valve as soon as the static pressure exceeds the value set on the va-lve (see Figure 23).

Note: To set the valve to the required pres-sure, please proceed as follows: - Remove the cap nut (1) - Loosen the lock nut (3) by twisting

in a counter-clockwise direction and set the pressure screw (2) to the required

- Screwing it lower will increase the pressure

- Screwing it higher will reduce the pressure

- Next, tighten the lock nut (3) again by twisting in a clockwise direction

Fig. 23: Installation example with overflow valve

Caution! Risk of damage to the cooling medium pump from contaminants in the cooling medium circuit! Rinse out the cooling me-

dium circuit before connecting to the Chil-ler.

The cooling medium outlet (see (10) Figure 5-8) of the Chiller must be connected to the cooling medi-um inlet of the equipment. At the same time, the cooling medium inlet (see (9) Figure 5-8) of the Chiller must be connected to the cooling medium outlet of the equipment. Please note the following: - To prevent condensation, always connect the

equipment using insulated pipelines and/or ho-ses.

- The nominal width of the pipework should be at least equivalent to the nominal width of the me-dium connections on the device.

- The pipework must be suitable for the maximum pressure (see chapter 15.4).

Note: The use of steel pipes, zinc-plated steel pipes and transparent hoses is not permitted.

Before commissioning, the cooling medium pump must be filled with cooling medium and vented (for further details, refer to chapter 6).

Note: With the water-cooled condenser (opti-onally available), make the cooling water connections with the requisite volumetric flow (as per the diagram in the R+ID fluid plan).

Caution! If the liquid to be cooled contains solid particles, we recommend installation of a mechanical filter upstream of the cooling medium inlet. In order to en-sure regular cleaning, two shut-off valves should additionally be installed.

5.5 Notes on electrical installation

Danger! It is vital to observe the following in-structions.

- When carrying out the electrical installation, it is

important to observe all valid national and regi-onal regulations as well as the provisions of the responsible power supply company. The electri-cal installation may only be performed by a qua-lified electrician who is responsible for compli-ance with the applicable standards and regulations.

A = Magnetic valve B = Non-return valve

A = Overflow valve

EN - The connection voltage and frequency must match the nominal values stated on the rating plate.

- No additional temperature control may be connected upstream of the unit at the supply end.

- Set the pre-fuse (motor circuit-breaker) as per the specifications on the rating plate.

- The mains connection must ensure low-noise potential equalisation. The device must be in-corporated into the potential equalisation sys-tem of the building.

- The cross-sections of the connection cable must be consistent with the rated current (see rating plate).

- The unit does not have its own overvoltage pro-tection. Measures must be taken by the opera-tor at the supply end to ensure effective protec-tion against lightning and overvoltage. The mains voltage must not exceed a tolerance of ±10%.

- In accordance with IEC 61 000-3-11, the unit is intended solely for use at sites with a conti-nuous current-carrying capacity (incoming mains power supply) of more than 100 A per phase and with a supply voltage of 400/230 V. If necessary, the power supply company must be consulted to ensure that the continuous current-carrying capacity at the point of connection to the public grid is sufficient for connection of such a unit.

- The connection must be made with a clockwise phase sequence rotation. The direction of rota-tion can be measured from connection clamps L1, L2 and L3. By connecting in a clockwise phase sequence, you will ensure that all rotary current motors have the correct direction of rota-tion.

Caution! Electrical connection with 460 V / 60 Hz

If your machine uses an auxiliary supply of 24 V AC and you wish to operate your Chiller at 460 V/3~/60 Hz, it is necessary to rewire the trans-former. This transformer assignment must be car-ried out by an authorised, trained member of staff prior to installation, observing all safety require-ments.

Note: The guarantee is not affected by this rewiring.

Note: In its delivered state, the transformer is defined to a supply voltage of 400 V.

Disconnect this connection and re-assign it to 460 V (see Figure 24).

Fig. 24: Transformer connection 5.5.1 Connecting the voltage supply The devices are wired ready for connection in the factory, and equipped with a connection cable (3 m long). Make the electrical connection as shown in the circuit diagram (see wiring plan in chapter 15).

5.5.2 Retrieving a system message You may additionally retrieve system messages (warnings & alarms) via a floating contact on the connection clamp of the Chiller. Suitable wires for this purpose are already provided in the connection cable (3, 4 and 5) and connected inside the device.

Note: Connect the suitably labelled wires in the connection cable to the controller as shown in the electrical circuit dia-gram (see Figure 25).

6 Commissioning

EN 5.5.3 External activation The Chiller is prepared for control via an external signal. To this end, the customer should connect contacts 1 and 2 on the signal cable.

Caution! If you are using external activation, the bridge implemented in the factory must be removed.

5.6 Room temperature sensor (optional) The Chiller supports room temperature-led control (see chapter 7.2.4). To this end, a room temperature sensor (cable length from Chiller: 4 m) is required, which is available as an optional accessory, see spare part list chapter 15.3. The cable entry is on the rear of the Chiller (see (14) Figure 5-8). The electrical connection is described in chapter 15.2. The activation parameters are described in chapter 7.

5.7 Installing the filter mats (optional) With coarse dust and oily ambient air, we recom-mend installing an additional metal filter mat (available as an accessory, see chapter 11) in the Chiller. Please proceed as follows (see Figure 26): 1. Remove the protective grille from the rear of the

Chiller by loosening the 4 screws 2. Push the filter mat (1) into the top recess 3. Press the filter mat lightly against the membra-

nes of the condenser heat exchanger 4. Allow the filter mat (1) to slide into the bottom

recess

6 Commissioning The Chiller has a red (optionally available in black) master switch (see (2), Figure 1-4). Rotate it by a quarter-turn in a clockwise direction to ready the machine for operation.

6.1 Cooling medium As standard, these units are not suitable for operati-on below the prescribed minimum temperature (see chapter 15.4), unless you have selected the option "winter control" for an extended ambient tempera-ture range. Generally speaking, a water-glycol mixture with a maximum glycol proportion of between 20 and 34 % by volume should be used as the cooling medium. We recommend our ready-mixed "Cooling medium for chillers" (see chapter 11). Other water-glycol mixtures may be possible in individual cases, but only by arrangement with the manufacturer. For further information, please refer to chapter 8.

Tab. 7: Model Numbers, cooling medium for chillers

Caution! Other additives may damage the pipelines and the seal of the cooling medium pump, and are therefore only admissible by ar-rangement with Rittal.

In order to avoid problems in the cooling medium circuit (including water-cooled units), it is essential that the VGB cooling water guidelines (VGB-R 455 P) are observed. The correct glycol concentration proportions may be read and determined using a refractometer.

6.2 Filling the cooling medium - Ensure that any shut-off valves built into the

cooling medium circuit are open. - Fill the cooling medium into the Chiller tank via

the filling nozzle (see (1), Figure 27).

6 Commissioning

EN - The correct fill volume (between minimum and maximum) may be read from the water level display (see (2), Figure 27) on the outside of the tank without having to open the door of the Chil-ler.

Note: If the compressor and the condenser fan fail to start up, the temperature of the filled cooling medium is lower than the setpoint temperature. You should therefore temporarily reduce the set-point temperature (see chapter 7).

Fig. 27: Filling the cooling medium (shwon 3335.790)

6.3 Venting the cooling medium pump Vent the cooling medium pump (with the system at a standstill) by loosening the vent screw (see (1), Figure 28) a little. As soon as cooling medium flows out, re-tighten the screw.

Fig. 28: Venting the cooling medium pump

Note: With a water-cooled condenser (opti-onally available), you must activate the external condenser circuit for the condenser (optionally by the opera-tor). Check the connection lines and pipe connections for leaks during commissioning.

6.4 Commissioning procedure Please observe the general procedure when com-missioning the Chiller:

Phase Description

1. Read the ma-nual

Ensure that the operator of the Chiller has read and understood the operating instructions. Also, please ensure that all valid provisi-ons are adhered to and the safety systems referred to in this manual have been set up.

2. Open the sys-tem valves

Open the shut-off valves (if installed) on the inlet and outlet of the Chiller. Do not open the manual bypass valve or overflow kit (if instal-led) (refer to overflow kit instructions).

3. Fill the cooling medium

Fill the Chiller with cooling medium as per the rating plate (see also chapter 6.2).

4. Establish the voltage supply

Supply the Chiller with voltage as per the rating plate.

Next, twist the red master switch to ON. Caution! If power is supplied by a generator, always en-sure that the generator is running normally before swit-ching on the Chiller.

5. Wait for the controller to reboot

After switching on the Chiller, the electronic controller will take about 30 seconds to reboot. After this, the cooling medium pump will start up. The factory setting is 18°C. If the temperature of the liquid to be cooled is below this, the compressor and fan will fail to start. Caution! If the phase positi-on is incorrect, a correspon-ding alarm will appear on the display. Implement a phase change after disconnecting the power.

6. Top up the cooling medi-um

With the pump operational, the cooling medium will start to circulate throughout the

Fig. 30: Basic functions Switch the Chiller on and off: When switching the Chiller on for the first time, please note that after pressing the master switch (see (2) Figure 1-4) and ending the reboot phase, the Chiller will be in standby mode. For this reason, in order to switch it on, it is additionally necessary to press the key combination "set" + "C". The Chiller is switched off into standby mode by pressing the key combination "set" + "F". Alternatively, the device can also be disconnected from the mains directly via the main switch (see also Figure 30).

Temperature displays During operation, as well as the inlet temperature (OUT), it is also possible to display the ambient temperature (Anb) (only with optionally available external temperature sensor) and the temperature on the plate heat exchanger (anti-freeze sensor) (TA). To do so, press the "F" or "C" keys during operation until the required sensor is displayed, and confirm your selection with "set". Pressing the "set" key again will return you to the start menu.

Apart from these basic functions (see also Figure 30), changes to the parameters may only be made in the appropriate levels (see chapter 7.2.2).

Note: The Chiller can only be switched into standby mode in its original state (dis-play of the inlet temperature during operation).

Note: The "Out" display is identical to the inlet temperature shown during operation.

EN 7.2.2 Access levels The parameters are accessed via menus, which are located at three different levels. Beispiel: The parameter dLP allows you to set the delay time of the low-pressure switch when starting up the compressor (between 0-60 sec.). This parameter is located in menu _di. This in turn is accessed via the customer level. The following diagram illustrates the system and provides an overview of the three levels and their menus. The parameters for the respective menus may be found in chapter 7.

For simplification purposes, the basic level is refer-red to below as "BS", the customer level as "CU, and the manufacturer level as "MN". Access to the basic level is achieved by holding down the "set" key (for approximately 2 seconds). The customer level can only be accessed by entering the customer password: 22. The manufacturer level is reserved for trained service staff and is only accessible by entering the manufacturer password. This pass-word, together with the parameters for the manufac-turer level, is not covered by this documentation but may be requested from our technical service (see chapter 9 for service contacts). Access to the respective levels is explained in greater detail in chapter 7.2.3.

7 Operation

EN 7.2.4 Types of operation (control mode) As a general rule, there are two different operating modes:

No.: Operating mode Application

1 Absolute (fixed value control)

To be used if the application requires a constant medium temperature

2 Relative (ambient tem-perature-led control)

To be used if the application requires a medium temperature that varies depending on the ambient temperature. Adjustment of the medium temperature to the ambient temperature may be set here (e.g. so that the medium temperature is always 2°C below the ambient temperature). However, it is limited by the limits PJr and PYr. This application requires an external temperature sensor (optionally available)

3 Combined control To be used when a combination of the relevant and absolute operating modes is required. Depending on the ambient temperature, the target value is thus either constant (absolute) or variable (relative). With due regard for the adjustable upper and lower limit values.

Tab. 10: Overview of operating modes Operating mode 1 – Absolute (fixed value control)

Operating mode to be used if the Chiller requires a constant medium temperature. PSr = Set value Pdr = Hysteresis If the medium temperature is above "PSr+Pdr", the Chiller is switched on. If it is below "PSr", the Chiller is switched off. The selectable parameters are: - PAr = ABS (standard) - PSr = Set value (standard: +18°C) - Pdr = Switching difference (standard: 2K) - PJr = Smallest value that may be set (standard: 10°C) - PYr = Highest value that may be set (standard: 25°C)

Fig. 33: Fixed value control

Note: The limits PJr and PYr are preset in the factory to 10°C (PJr) and 25°C (PYr). The set value PSr may therefore only have a value within this range. If a set value of > 25°C is required, you must first adjust the limit PYr (see chapter 7.2.5).

EN Operating mode 2 – Relative (ambient temperature-led control) To be used if the application requires a medium tempera-

ture that varies depending on the ambient temperature. AMB = Ambient temperature PSr = Set value as the difference from the ambient tempe-rature Pdr = Hysteresis Set value = AMB + PSr For the majority of applications, the set value must be below the ambient temperature. The PSr value must therefore be negative. If the medium temperature is above "PSr+Pdr", the Chiller is switched on. If it is below "PSr", the Chiller is switched off. We recommend a negative value of -2 for PSr. The selectable parameters are: - PAr = REL - PSr = Set value as the difference from the ambient

temperature. We recommend the use of values <0, such as PSr=-2

- Pdr = Hysteresis - PJr = Minimum set value - PYr = Maximum set value

Example: PSr = -2 K Pdr = +5 K AMB = 15°C Kon = AMB + PSr + Pdr = 15 + (-2) + 5 = 18°C With these parameters, the Chiller will start to cool at a medium temperature of 18°C Koff = AMB + PSr = 15 + (-2) = 13°C Upon reaching the set value of 13°C, the Chiller will swtich off. Kon = Chiller ON Koff = Chiller OFF

Fig. 34: Ambient temperature led control

Note: Negative values for parameter PSr will mean a set value below the ambient temperature (and vice versa). Please note that the entry for PSr is limited by the parameters PJr and PYr. As such, you will need to modify these limits first (see chapter 7.2.5).

7.2.6 Hot gas bypass control (optional) A hot gas bypass control (hereinafter abbreviated to HGBP) refers to a circuit with a controllable bypass circuit from the high-pressure to the low-pressure side (see P+ID cooling circuit) with an infeed between the expansion valve and the evaporator coil (see Figure 40). Key to Figure 40: 1 Compressor 2 Condenser 3 Expansion valve 4 Evaporator coil 5 HGBP control valve

Fig. 40: Cooling circuit with HGBP valve The control valve (5) in the bypass circuit remains closed when the cooling demand is high. The Chiller will then supply its full output. If the required output is reduced, the HGBP valve is continuously opened via the controller. Hot gas will then flow via the by-pass circuit to the evaporator coil input (4). There, it is mixed with the refrigerant flowing out of the ex-pansion valve and cooled down. As a result, the mixture partially evaporates in the supply line to the evaporator coil, causing the evaporation tempera-ture to rise, and the cooling output to decrease. Overheating of the extracted gas upstream of the compressor is monitored and regulated by the ex-pansion valve. The HGBP control is used if an hysteresis of < 2 K is required. The maximum medium temperature hysteresis achievable with this control is 0.5 K. If

8 Inspection and maintenance

EN 8 Inspection and maintenance Regular, professional inspection and maintenance (once a year is recommended) and the sole use of original spare parts is crucial for fault-free operation and a long service life of the Chiller. With this in mind, we recommend that you sign a maintenance agreement.

Note: We offer a maintenance service! Our service contact details: Telephone: +49 2772 505-1855 Fax: +49 2772 505-1850 E-mail: service@rittal.de

Tab. 15: Inspection and maintenance activities

8.1 Servicing the cooling circuit As a hermetically sealed system, the cooling circuit has been filled in the factory with the required amount of refrigerant, and tested for leaks and sub-jected to a function trial run.

Caution! Maintenance work on the circuit may only be carried out by specialist refri-geration firms as per Directive (EC) 307/2008. We therefore advise you to sign a maintenance contract which includes annual inspection of the coo-ling circuit (European Directive EC No. 842/2006 / F Gases Directive). Directi-ve (EC) 842/2006 or Chemical Climate Protection Directive.

8.2 Cooling medium

8.2.1 General remarks When cooling the water-glycol mixture in an open circuit, always remember that solid residues, algae, deposits and corrosion can damage the Chiller. Residues will always impair the performance of the Chiller. Satisfactory conditions can rarely be achie-ved without water treatment. Ensure that deposits and corrosion are avoided, even under extreme conditions, by means of regular monitoring of the cooling medium quality and treatment of the cooling medium.

8.2.2 Cooling medium requirements The cooling medium must not cause any limescale deposits or loose debris. In other words, it should have a low level of hardness, particularly carbonate hardness. Particularly when cooling in circulation mode, it is especially important that the carbonate hardness is not too high. On the other hand, the water should not be so soft that it attacks the mate-rials. When recooling the cooling water, the evaporation of large quantities of water must not cause an in-crease in the salt content, since electrical conducti-vity increases as the concentration of dissolved substances rises, and the cooling medium thereby becomes more corrosive. For this reason, not only is it always necessary to add a corresponding quantity of fresh water, but also to remove part of the enri-ched cooling medium. Furthermore, the properties of the water used must not deviate from the following list of hydrological data:

Property Value pH value (7) 7.5 – 8.5

Electrical conductivity 200 – 1000 µS/cm

Evaporation residue < 500 mg/dm³

Depositable sub-stances

< 3 mg/dm³

Hardness 3 – 8°dH (in German-speaking regions)

Ca + Mg 0.5 – 2 mmol/l (in the international environment)

EN Property Value Hydrogen carbonate 1 – 5 mmol/dm³

(60 – 300 mg/dm³)

Free CO2 < 10 mg/dm³

Sulphide < 0.01 mg/dm³

Chloride < 50 mg/dm³

Sulphate < 250 mg/dm³

Nitrate < 25 mg/dm³

Nitrite < 0.1 mg/m³

COD < 7 mg/dm³

NH4 < 0.05 mg/dm³

Fe < 0.1 mg/dm³

Mn < 0.1 mg/dm³

Cu < 0.1 mg/dm³

Tab. 16: Hydrological data

Caution! The cooling medium may thicken as a result of evaporation. With a full exchan-ge of cooling medium, you can adjust the values to the framework conditions. Distil-led or deionised water should only be used in Chillers designed specifically for this purpose (see data sheet, chapter 15.4).

8.2.3 Preparation and care Depending on the type of installation to be cooled, certain requirements are placed on the cooling me-dium. According to the level of contamination and the size and design of the Chillers, a suitable pro-cess is used to prepare and/or maintain the cooling medium. The most common types of contamination and most frequently used techniques to eliminate them in industrial cooling are shown in the following table:

Type of impurity Removal

Mechanical contaminati-on

Filter the cooling water with a screen filter, gravel filter, cartridge filter, pre-coated filter

High level of hardness Soften the cooling medium via ion exchange

Moderate levels of me-chanical contaminants

Add stabilisers and/or dispersing agents to the

and hardeners water

Moderate levels of che-mical contaminants

Add passifiers and/or inhi-bitors to the cooling medi-um

Biological contaminants, slime bacteria and algae

Add biocides to the cooling medium

Tab. 17: Impurities and removal

8.2.4 Recommended "cooling medium for chillers"

Rittal recommends the use of "cooling medium for chillers" (water-glycol mixture). This is a ready-mixed solution and is therefore suitable for immedia-te use (without the need for mixing) (see Table 19 + 20). Glykol + Wasser

20 – 30 % max. 70 – 80 % max.

EN 8.2.5 Monitoring the cooling medium - Regularly check the fill level of the cooling medi-

um tank - Regularly check the quality of the cooling medi-

um, and if necessary, improve it as described under 8.2.3.

- Regularly measure the glycol content using a refractometer (see Figure 42). If you have any questions, please contact our service depart-ment.

- In order to prevent the formation of fungus and algae, the cooling medium should be replaced at least once a year. The use of pure water may also cause the formation of fungus or algae.

- If the Chiller is used under certain physical con-ditions (Tw < 10°C), condensation may form in the system. This can be minimised by means of suitable insulation or the optionally available ambient temperature-led control.

Refractometer

Fig. 42: Refractometer

Caution! The manufacturer's guarantee and war-ranty will be invalidated in case of impro-per use and treatment of the Chiller. In order to avoid problems in the cooling/heat transfer circuit (even on water-cooled devices), observance of the VEB cooling medium guidelines (VGB-R 455 P) is es-sential (for reference sources, please refer to chapter 12).

8.3 Cleaning the condenser In order to ensure problem-free operation of the Chiller, the membranes of the air-cooled condenser must be kept clean. Cleaning should take place at regular intervals (at least once per half year), whereby the frequency depends on the level of contamination in the installation rooms. Oily ambient air, in conjunction with dust, will result in increased levels of contamination of the conden-ser membranes. In such cases, thorough cleaning with compressed air is only possible under certain circumstances. In such cases, the additional use of a metal filter mat is required (see chapter 5.7).

When cleaning, please proceed as follows: 1. First, decommission the unit by switching off the

power supply to the master controller and securing it against reactivation.

2. The condenser membranes are located on the rear of the Chiller (see (1) Figure 43). To expo-se them, first remove the protective grille as described under chapter 5.7 and/or remove the optionally installed filter mat.

3. Next, clean the condenser with compressed air (see Figure 44) and then fit the protective grille and/or the filter mat again.

Fig. 43: Condenser membranes

Fig. 44: Clean the condenser

When cleaning, it is essential to observe the safety notices and warnings below.

9 Troubleshooting

Danger! Disconnect the Chiller from the power before carrying out any maintenance and inspection work.

Danger! Temperatures of up to 60°C may occur inside the unit. Wait around 10 minutes after switching the unit off to give the line sufficient time to cool down.

Danger of cuts! The condenser membranes have sharp edges. Always wear gloves for your per-sonal safety.

Caution! Risk of damage to the condenser memb-ranes if using excessive compressed air force. Meter the compressed air carefully to avoid damage.

8.4 Cleaning the filter mat (optional) The metal filter mat may likewise be cleaned using compressed air. To do so, remove it from its holder (see chapter 5.7).

8.5 Draining the cooling medium tank Empty the cooling medium tank directly via the tank drain nozzle (see (1) Figure 45) or using a hose into a container. When disposing of the cooling medium, always observe the locally valid water protection guidelines.

Fig. 45: Empty the tank

9 Troubleshooting Whilst operational, the Chiller operates safely by keeping the inlet temperature of the cooling medium at the set level. Possible reasons for a deviation from the setpoint may include: - Excessive cooling demands - Ambient temperature too high - Failure to observe the necessary distances - Contaminated evaporator coil - Contaminated condenser - Lack of refrigerant - Insufficient cooling medium level in the tank - Cooling medium temperature set too low - Incorrectly set parameters The malfunctions must only be rectified by trained, specialist personnel. For fault analysis, please con-sult Table 14-15 or speak to our service department: Service contacts: Rittal International Service Auf dem Stützelberg 35745 Herborn, Germany Telephone: +49(0)2772 505-1855 Fax: +49(0)2772 505-1850 E-mail: service@rittal.de

10 Decommissioning and disposal

EN 10 Decommissioning and disposal Decommissioning and disposal of the Chiller may only be carried out by authorised, specialist person-nel. The unit will need to be deactivated by dis-connecting it from the mains.

10.1 Decommissioning If the Chiller is out of service for a long period (more than six months), the cooling circuit will need to be drained. This will prevent the evaporation of water, and the water-glycol ratio of the cooling medium will not be altered (the pump seal could be destroyed due to glycol thickening). To decommission, please proceed as follows: - Disconnect the unit from the power supply and

protect against reactivation. - Dismantle the connections of the cooling medium

circuit. - Drain the cooling medium circuit as described

under chapter 8. - To recommission, proceed as described under

chapter 6.

10.2 Disposal - When disposing of the cooling medium, always

observe the locally valid water protection guide-lines. In Germany this is the Federal Water Act (Wasserhaushaltsgesetz).

- For proper disposal of the Chiller, please notify your supplier or our service department.

Caution! Intentional release of the refrigerant is prohibited. Refrigerant must be professio-nally disposed of.

Certification to BGR 500 chapter 2.35 and DIN EN 378-2

14 Maintenance register

EN 14 Maintenance register Regular inspections are prescribed by law and regulated by European Regulation 842/2006 of 17 May 2006, excerpts from which are shown below. However, this is no substitute for a detailed knowledge of the Regu-lation itself. 1. Inspections must be carried out by certified personnel and with due regard for Article 5 of the provisions.

2. All inspections should be registered on a maintenance certificate (pages to follow).

3. The volumes of refrigerant contained in the machine are shown on the rating plate.

4. The inspection periods for machines vary according to whether or not they are hermetically sealed (see

label with technical specifications)

5. If gas escapes and is followed by a machine repair, a further inspection should be carried out one month

after the repair in order to ascertain any losses.
