1 Notes on documentation

1.1 CE labelling

Rittal GmbH & Co. KG confirms the conformity of the cooling unit with the European Union's Machinery Directive 2006/42/EC and EMC Directive 2014/30/EC. A corresponding declaration of conformity has been issued. This can be found at the end of this document, or on the Rittal homepage.

1.2 Storing the documents

The assembly and operating instructions as well as all other applicable documents are an integral part of the product. They must be issued to everyone who works with the unit and must always be available and on hand for operating and maintenance personnel.

1.3 Symbols used in these operating instructions

The following symbols are used in this documentation:

Danger! A dangerous situation in which failure to

comply with the instructions will result in death or severe injury.

Warning! A dangerous situation which may cause death or serious injury if the instructions are not followed.

Caution! A dangerous situation which may lead to

(minor) injuries if the instructions are not followed.

1.4 Other applicable documents

Assembly and operating instructions in paper and digital format are available for the unit types described here. We cannot accept any liability for damage associated with failure to observe these instructions. Where applicable, the instructions for any accessories used also apply.

2 Safety notes

Please observe the following general safety notes when transporting, assembling and operating the unit:

– Assembly, installation and servicing may only be per-

formed by properly trained specialists.

– Screw the enclosure to the floor to prevent it from tip-

ping over when the cooling unit is installed.

– Do not obstruct the air inlet and air outlet of the cooling

unit inside and outside the enclosure (see section4.2.2 "Layout of the electronic components in the enclosure").

– To ensure problem-free opening and closing of the en-

closure door, use a ride-up door roller (refer to the accessories in the Rittal Catalogue). This raises the door slightly and balances out the weight of the cooling unit, to prevent buckling of the door and associated seal problems.

– The heat loss of the components installed in the enclo-

sure must not exceed the useful cooling power of the cooling unit.

– The cooling units must not be transported in closed

vehicles.

– Cooling units with item numbers: 3303.xxx, 3304.xxx

and 3305.xxx must be transported in an upright position and protected from tipping over.

– Shipping braces must be used when transporting a

unit that has already been mounted (on the enclosure). A wooden structure made from square timbers or boards to support the cooling unit at the bottom (see fig. 1) is suitable for this purpose. The pallet should be big enough to prevent the enclosure and cooling unit overturning. If the cooling unit is mounted on a door, ensure the door is kept closed during transport.

Note: Important notices and indication of situations

which may result in material damage.

Danger! Extremely flammable gas. Contains gas under pressure; may explode if heated.

 This symbol indicates an "action point" and shows that

you should perform an operation or procedure.

3.1 Functional description

3.1.1 How it works

The cooling unit (compression refrigeration system) comprises four main components (see fig. 3): the evaporator (1), the refrigerant compressor (2), the condenser (3), and the control or expansion valve (4), which are connected by suitable pipework. This circuit is filled with a readily boiling substance, the refrigerant. The refrigerant R1234yf (C tion Potential (ODP) is 0, making it very eco-friendly. A filter dryer (5) which is integrated into the hermetically sealed cooling circuit provides effective protection against moisture, acid, dirt particles, and foreign bodies within the cooling circuit.

Fig. 3: Cooling circuit

In the evaporator coil (1), the liquid refrigerant is converted to a gaseous state. The energy needed for this purpose is taken from the enclosure air in the form of heat, which has the effect of cooling the enclosure air. In the compressor (2), the refrigerant is heavily compressed, so that it achieves a higher temperature inside the condenser (3) than the ambient air. This means that excess heat may be emitted to the ambient air via the surface of the condenser, as a result of which the temperature of the refrigerant drops and it is converted back into liquid. It is re-injected into the evaporator coil via a thermostatic expansion valve (4), which causes it to cool down further, and is then once again able to absorb the energy from the enclosure air in the evaporator coil. The whole cycle begins again.

3.1.2 Control

The Rittal enclosure cooling units are fitted with an e-Comfort controller for setting the functions of the cooling unit (see section6 "Operation").

3.1.3 Bus mode

The serial unit interface X2 allows you to create a bus connection with up to ten cooling units using the masterslave cable (shielded, four-wire cable, Model No.

3124.100). This allows you to implement the following functions:

– Parallel unit control (the cooling units in the network

– Parallel door status message ("door open") – Parallel collective fault message Data is exchanged via the master-slave connection. During commissioning, assign an address to each unit that also includes the identifier "master" or "slave".

3.1.4 Safety devices

– In the cooling cycle, the cooling units have a tested

– Temperature monitoring prevents the evaporator coil

18 Rittal enclosure cooling unit

can be switched on and off simultaneously)

pressure switch to EN 12 263 which is set to maximum PS (permissible pressure); this operates via an automatic reset device whenever the pressure drops again

from icing over. If there is a risk of icing, the compres-

sor switches itself off and automatically switches itself back on again at higher temperatures

– The refrigerant compressor and the fans are equipped

with thermal winding shields to protect against excess current and excess temperatures

– In order to allow a reduction of pressure inside the

compressor and hence a safe restart, once it has been switched off (e.g. upon reaching the set temperature via the door limit switch function or via de-energising), the device will switch back on with a delay of 180 seconds

– The device has floating contacts on the connection

pins (terminals 3 – 5), via which system messages from the device may be polled, e.g. using a PLC (1 x change-over contact Basic controller, 2 x normally open contacts e-Comfort controller)

3.1.5 Condensation

At high levels of humidity and low temperatures inside the enclosure, condensation may form on the evaporator coil.

The cooling units (except 3303.xxx) have automatic, electric condensate evaporation. The thermal component used for this purpose is based on self-regulating PTC technology. Condensate arising on the evaporator coil is collected in a tank in the external circuit of the cooling unit, and partially evaporated via the airflow. When the water level rises, the water enters the PTC thermal component and is evaporated (through-flow heater principle). The water vapour streams out of the cooling unit with the airflow from the external fan.

The PTC thermal component is permanently connected and has no switchpoint. It is protected against short-circuits with miniature fuses (F1.1, F1.2). If the fuse has tripped, any condensation is drained off via the safety overflow. For unit types 3303.xxx, the condensate is routed downwards out of the unit via a drain pipe on the evaporator coil divider panel. For this purpose, a hose must be connected to the condensate nozzle (see section4.4 "Connecting the condensate discharge"). External condensate evaporators are available as accessories for these unit types (refer also to the accessories in the Rittal Catalogue).

3.1.6 Filter mats

The entire cooling unit condenser is covered with a dirtrepelling, easy-to-clean RiNano coating. In many applications, therefore, the use of filter media is unnecessary, particularly with dry dusts.

For dry, coarse dust and lint in the ambient air, we recommend installing an additional PU foam filter mat (available as an accessory) in the cooling unit. Depending on the incidence of dust, you will need to replace the filter mat from time to time.

For air containing oil condensate, we recommend the use of metal filters (also available as an accessory).

4 Assembly and connection

These may be cleaned with suitable detergents and reused.

Function of the filter mat monitor:

Dirt on the filter mat is automatically determined by measuring the temperature difference in the external circuit of the cooling unit. As the level of filter mat soiling increases, the temperature difference will increase. The setpoint value of the temperature difference in the external circuit adapts automatically to the relevant operating points in the performance diagrams. Hence there is no need to readjust the setpoint value for different unit operating points.

3.1.7 Door limit switch

The cooling unit may be operated with a floating door limit switch connected. The door limit switch is not included with the supply (available as an accessory, Model No. 4127.010). The door limit switch function causes the fans and the compressor in the cooling unit to be switched off after approximately 15 seconds when the enclosure door is opened (contacts 1 and 2 closed). This prevents the formation of condensation inside the enclosure while the enclosure door is open. In order to prevent damage to the unit, it is equipped with an ON delay: The evaporator fan cuts back in with a delay of approximately 15 seconds after the door has been closed, while the condenser fan and compressor switch on after approximately 3minutes.

Note: – No external voltage may be applied to the

door contacts (terminals 1 and 2).

– For cooling units with basic control, the

evaporator fan continues to run even when the door is open.

3.1.8 Additional interface X3

Note: The electrical signals at the interface are of an extra-low voltage (not extra-low safety voltages to EN 60 335).

The cooling unit is state of the art and built according to recognised safety regulations. Nevertheless, improper use can pose a threat to the life and limb of the user or third parties, or result in possible damage to the system and other property.

Consequently, the cooling unit must only be used properly and in a technically sound condition! Any malfunctions which impair safety should be rectified immediately.

Proper use also includes the observance of the documentation provided, and compliance with the inspection and maintenance conditions.

Rittal GmbH & Co. KG is not liable for any damage which may result from failure to comply with the documentation provided. The same applies to failure to comply with the valid documentation for any accessories used. Inappropriate use may be dangerous. Examples of inappropriate include:

– Use of the cooling unit over long periods with the en-

closure open. – Improper operation. – Improper rectification of malfunctions. – Use of accessories not approved by Rittal GmbH &

Co. KG.

The cooling unit is only intended for cooling connected enclosures. Any other use is not permitted.

– The unit must not be installed and operated in loca-

tions which are accessible to the general public (see DIN EN 60335-2-40, paragraph 3.119).

– The unit is designed solely for stationary use.

Rittal enclosure cooling unit 19

When choosing the installation site for the enclosure, please observe the following: – The site for the enclosure, and hence the arrangement

of the cooling unit, must be carefully selected so as to

ensure good ventilation (clearance between units and

clearance between the unit and the wall must be at

least 200 mm in each case).

4 Assembly and connection

– The cooling unit must be installed and operated in a

vertical position (maximum deviation: 2°).

– The SK 33xx.xxx devices must not be assembled in in-

stallation rooms smaller than 4 m³.

– The installation site must be free from excessive dirt,

aggressive ambient conditions and moisture.

– The ambient temperature must be within the limits

specified on the rating plate.

– It must be possible to fit a condensate discharge (see

section4.4 "Connecting the condensate discharge").

– The mains connection data as stated on the rating

plate of the unit must be guaranteed.

– The enclosure to be cooled must not have additional

openings for ventilation. This will prevent the supply of oxygen to any potential fire.

– The device should only be kept in rooms that do not

contain continuous sources of ignition (e.g. open flames, powered gas appliance or electric heater).

4.2 Notes on assembly

4.2.1 General

Caution! The cooling circuit contains volatile,

flammable gases.

Fig. 4: Never direct the cold airflow at active components

Air diversion components are available as accessories – please refer to the Rittal Catalogue.

It is important to ensure even air circulation inside the enclosure. Under no circumstances should air inlet and outlet openings be obstructed, otherwise the cooling performance of the unit will be reduced. Ensure the distance "x" (see fig. 5) from components and other installed enclosures so that the required air circulation is not obstructed and prevented.

– Check the packaging carefully for signs of damage.

Traces of oil on damaged packaging are an indication of refrigerant loss and leakages. Any packaging damage may be the cause of a subsequent functional failure.

– The enclosure must be sealed on all sides (IP 54). In-

creased condensation will occur if the enclosure is not airtight.

– In order to avoid excessive condensation inside the

enclosure, we recommend installing a door limit switch (e.g. 4127.010) which deactivates the cooling unit when the enclosure door is opened (see section3.1.7 "Door limit switch").

4.2.2 Layout of the electronic components in the enclosure

Note: Risk of condensation!

When arranging the electronic components inside the enclosure, please ensure that the cold airflow from the cooling unit is not directed at active components. Please also ensure that the cold airflow is not directed at the warm exhaust airflow from active components such as converters. This may lead to an air short-circuit and therefore prevent adequate climate control, or may even cause the cooling unit’s internal safety devices to cease cooling operation.

 Route the condensate hose to a drain or into the ex-

ternal condensate evaporator (refer to Accessories in the Rittal Catalogue).

4.5 Notes on electrical installation

When performing the electrical installation, it is important to observe all valid national and regional regulations as well as the provisions of the responsible power supply company. The electrical installation may only be carried out by a qualified electrician who is responsible for compliance with the applicable standards and regulations.

4.5.1 Connection data

– The connected voltage and frequency must corre-

spond to the values stated on the rating plate

– The cooling unit must be connected to the mains via

an all-pin isolating device, which ensures at least 3 mm contact opening when switched off

– No additional temperature control may be connected

upstream of the unit at the supply end

– Install the protective device specified on the rating

plate to protect the line and equipment from short-circuits.

– The mains connection must ensure low-noise poten-

tial equalisation

4.5.2 Overvoltage protection and supply line load

– The unit does not have its own overvoltage protection.

Measures must be taken by the operator at the supply end to ensure effective lightning and overvoltage protection. The mains voltage must not exceed a tolerance of ±10%.

– In accordance with IEC 61 000-3-11, the unit is in-

tended solely for use at sites with a continuous 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 electricity 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 fans and compressors in single- and three-phase

units are intrinsically safe (thermal winding protection).

– Install the protective device specified on the rating

plate to protect the line and equipment from short-circuits (miniature circuit-breaker with appropriate characteristic – e.g. "K" characteristic – or gG standard type slow fuse, circuit-breaker for plant or transformer protection). Select a suitable circuit-breaker in accordance with the information specified on the rating plate: Set it to the minimum specified value. This will achieve the best short-circuit protection for cables and equipment. Example: Specified setting range 6.3 – 10 A; set to 6.3 A.

4.5.3 Three-phase devices

– The electrical connection for devices in the three-

phase version MUST be made with a clockwise rotating field

– The three-phase version of models 3304.xxx and

3305.xxx must be connected to a TN network with star earthing via a circuit-breaker for plant protection (current setting as per the rating plate). Three-phase units with special voltages must be protected with a circuit-breaker for transformer protection (category AC-3) as per the rating plate.

– Units designed for three phase 400/460 V feature ad-

ditional monitoring of the rotary field or the absence of a phase. If the rotary field is incorrect or a phase is absent, the unit will not run.

4.5.4 Door limit switch

– Each door limit switch must only be assigned to one

cooling unit.

– Several door limit switches may be connected in par-

allel to one cooling unit.

– The minimum cross-section for the connection cable

is 0.3 mm

– The line resistance to the door limit switch must not

exceed a maximum of 50 Ω.

– The door limit switch only supports a floating connec-

tion; no external voltages.

– The contact of the door limit switch must be closed

when the door is open. The safety extra-low voltage for the door limit switch is provided by the internal power pack: Current approx. 30 mA DC.

 Connect the door limit switch to terminals 1 and 2 of

the connector.

4.5.5 Notes on the flicker standard

The flicker limits specified in standard EN 61 000-3-3 or

-3-11 are adhered to, provided the supply impedance is less than approx. 1.5 Ω.

Where necessary, the unit operator should measure the connected impedance or consult the responsible electricity supply company. If there is no way of influencing the supply impedance and sensitive installed components (e.g. BUS) are subjected to interference, a line reactor or starting-current limiting device should be con-

for a cable length of 2 m.

24 Rittal enclosure cooling unit

nected upstream of the cooling unit to restrict the startup current of the cooling unit.

4.5.6 Potential equalisation

If, for EMC reasons, the unit is to be integrated into the customer’s existing potential equalisation system, a conductor with a larger nominal cross-section can be connected to the potential equalisation connection point (attachment points) on the wall-mounted cooling units.

According to the standard, the PE conductor in the mains connection cable is not classified as an equipotential bonding conductor.

4.6 Making the electrical connection

4.6.1 Bus connection (only when interconnecting several units with a Comfort controller)

When using several cooling units, the serial device interface X2 can be used to connect up to ten cooling units with the bus cable (Model No. 3124.100).

Note: The electrical signals at the X2 interface are of an extra-low voltage (not extra-low safety voltages in accordance with EN 60 335-1).

4 Assembly and connection

When interconnecting, please note the following: – De-energise the cooling units to be connected – Ensure proper electrical insulation – Make sure the cables are not laid in parallel to power

lines

– Make sure that the lines are short

Note: With the last slave unit in the group, do not, under any circumstances, connect the remaining socket of the Y cable 3124.100 into interface X3 of the cooling unit!

4.6.2 Connection X3 for serial interface

The interface card (Model No. 3124.200) may be connected to X3. This is used to evaluate system messages in a PLC, for remotely setting parameters and monitoring, or for integration into the facility management system.

4.7 Finalising assembly

4.7.1 Installing the filter media

The entire cooling unit condenser is covered with a dirtrepelling, easy-to-clean RiNano coating. In many applications, therefore, the use of filter media is unnecessary, particularly with dry dusts. For dry, coarse dust and lint in the ambient air, we recommend installing an additional PU foam filter mat (available as an accessory) in the cooling unit. For air containing oil condensate, we recommend the use of metal filters (also available as an accessory). When used in textile plants with heavy lint contamination, lint screens should be used (available as an optional extra).

 Pull the louvred air inlet grille off the enclosure.  Insert the filter mat into the louvred grille as shown in

fig. 22 and push it back onto the enclosure.

Fig. 23: Connect the display and attach the louvred grille

4.7.3 Setting the filter mat monitor with the e-Comfort controller

Function of the filter mat monitor: Dirt on the filter mat is automatically detected by meas-

uring the temperature difference in the external circuit of the cooling unit (see section6.1.6 "Programming overview"). As the level of filter mat soiling increases, the temperature difference will increase. The setpoint value of the temperature difference in the external circuit adapts automatically to the relevant operating points in the performance diagrams. Hence there is no need to readjust the setpoint value for different unit operating points.

Fig. 22: Installing the filter mat

4.7.2 Fitting the cooling unit

For partial and full internal mounting only.

 Connect the connector to the rear of the display.  Place the louvred grille onto the unit at the front, and

press it down until you hear it snap into place.

5 Start-up

Note: The oil must be collected in the compressor in order to ensure effective lubrication and cooling. Do not operate the cooling unit for at least 30 minutes after assembling the equipment.

 Once all the assembly and installation work is com-

plete, switch on the power supply to the cooling unit. The cooling unit starts running. The software version of the controller first appears for approx. 2 seconds, then "ECO" to show Eco mode is enabled. The internal enclosure temperature will then appear in the 7-segment display.

set option (e.g. t10) or the temperature. In regular operation, the display shows both the temperature (in degrees Celsius or Fahrenheit – users may switch between the two) and any error messages. The current internal enclosure temperature is usually displayed permanently. In the event of an error message, this alternates with the temperature display.

The unit is programmed using buttons 1 – 3 (fig. 24). The relevant parameters also appear in the display.

6.1.2 Eco mode

All Rittal TopTherm cooling units with e-Comfort controller from firmware 3.2 have the energy-saving eco mode, which is enabled in the delivered state.

The eco mode is used to save energy in the heat exchanger if there is no thermal load, or there is a low thermal load in the enclosure (e. g. standby operation, no production or weekend). During this process the evaporator fan in the internal circuit is switched off as appropriate if the actual internal enclosure temperature drops to 10 K below the specified setpoint temperature. To ensure the internal temperature is reliably measured during this process, the fan starts cyclically for 30 sec. every 10

minutes (see fig. 25). If the internal temperature drops to a range 5 K below the setpoint set again, the fan switches back to continuous operation.

If required, eco mode can be disabled on the control display. For this purpose switch the parameter from 1 to 0 in the programming level (see tab.3). The fan then runs continuously.

independently of the set temperature or door limit switch function.

 Simultaneously press buttons 1 and 2 (fig. 24) for at

least 5 sec.

The cooling unit will commence operation. Test mode is completed after approximately 5 minutes. The unit switches off and changes to normal operation.

6.1.4 General information about programming

Using buttons 1, 2 and 3 (fig. 24) you can change 24 parameters within the preset ranges (min. value, max. value). Tables 3 and 4 show the parameters which can be altered. fig. 26 on page 32 shows which buttons must be pressed.

Note on switching hysteresis:

With a low hysteresis and short switching cycles, there is a risk that cooling may not be adequate or that only partial sections of the enclosure are cooled. If the cooling unit and compressor run times are too long < 1 minute, the switching hysteresis to protect the cooling unit is automatically increased (see message "LH" in section 6.1.9 "Evaluating system messages").

"Cod" will appear in the display. In order to be able to change a value, you must enter the authorisation code "22".

 Keep the  programming button (°C) held down until

"22" appears.

 Press button 2 ("Set") to confirm the code.

You can now alter the parameter within the preset limits.

 Press one of the programming buttons  (°C) or

 (°F) until the required value appears.

 Press button 2 ("Set") to confirm the change.

You can now alter other parameters in the same way. There is no need to re-enter the authorisation code "22".

 To exit programming mode, press button 2 ("Set")

again for approximately 5 seconds.

"Acc" will appear in the display to indicate that the changes have been saved. The display then switches back to regular operation (internal enclosure temperature).

You can also program the e-Comfort controller using a diagnosis software package (Model No. 3159.100), which is supplied with a connection cable to the PC. The cable connector on the rear of the e-Comfort controller display serves as an interface.

Note on temperature settings:

With the e-Comfort controller, the temperature is preset at the factory to +35°C. In order to save energy, and due to the risk of increased condensation, do not set the temperature lower than that actually necessary.

Note on useful cooling power:

Interactive performance diagrams for calculating the useful cooling power may be found at www.rittal.com.

In principle, the programming is identical for all editable parameters. To enter programming mode:

 Press button 2 ("Set") for approx. 5 seconds.

The controller is now in programming mode. While in programming mode, if you do not press any buttons for approx. 30 seconds, the display will first flash, then the controller will switch back to normal display mode. "Esc" in the display indicates that any changes made have not been saved.

 Press the programming buttons  (°C) or  (°F) to

switch between the editable parameters (see tables 3 and 4).

Tab. 4: System messages that can be evaluated via relays

The system messages A1 – A19 may also be evaluated via two floating system message relays. In this way, one of the two system message relays may be allocated to each system message.

System message relays with normally open contact, see wiring diagrams in section 4.6.3 "Installing the power supply":

– Terminal 3: NO (normally open, relay 2) – Terminal 4: C (connection of the supply voltage to the

system message relay)

The RiDiag II software (available as an accessory, Model No. 3159.100) allows you to invert the system message relay circuit. In the normal operating state the two relays will then drop out. If a system message occurs, the relevant relay will energise and the contact will close.

Note: This setting can only be made using the

RiDiag II software.

– Terminal 5: NO (normally open, relay 1)

Program system messages with the value

The definition NO refers to the de-energised state. As soon as power is applied to the cooling unit, both system message relays (relay 1 and 2) energise. This is the normal operating state of the cooling unit. As

6.1.8 Setting the master/slave identifier

When several cooling units are connected together (maximum ten), one of the cooling units must be defined as the "master" and the others as "slaves". For this purpose, assign a corresponding identifier (address) to each cooling unit which will enable the cooling unit to be identified in the network.

If one of the slave units reaches the set temperature or if the door limit switch function is activated, the affected slave unit will report to the master unit, which then deactivates all the other cooling units.

Notes: – Only one unit may be configured as mas-

ter, and its identifier must match the number of connected slave units.

– The slave units must have different identi-

fiers.

– The identifiers must be numbered in as-

cending order without any gaps.

On the master cooling unit (00 = factory setting), set the number of slave units present in the network: – 01: Master with 1 slave cooling unit

– 02: Master with 2 slave cooling units – 03: Master with 3 slave cooling units – 04: Master with 4 slave cooling units – 05: Master with 5 slave cooling units – 06: Master with 6 slave cooling units – 07: Master with 7 slave cooling units – 08: Master with 8 slave cooling units – 09: Master with 9 slave cooling units

On the slave cooling unit (00 = factory setting), set its own address:

– 11: Slave cooling unit no. 1 – 12: Slave cooling unit no. 2 – 13: Slave cooling unit no. 3 – 14: Slave cooling unit no. 4 – 15: Slave cooling unit no. 5 – 16: Slave cooling unit no. 6 – 17: Slave cooling unit no. 7 – 18: Slave cooling unit no. 8 – 19: Slave cooling unit no. 9

Caution! Risk of fire!

Never use flammable liquids for cleaning.

7 Inspection and maintenance

Warning! The unit is live.

Switch off the power supply before opening, and take suitable precautions against it being accidentally switched back on.

Warning! Any essential repair work on the cool-

ing circuit must only be undertaken by Rittal.

The cooling circuit is a maintenance-free, hermetically sealed system. The cooling unit is filled with the required quantity of refrigerant at the factory, checked for leaks, and subjected to a functional test run.

The installed maintenance-free fans are mounted on ball bearings, protected against moisture and dust, and fitted with a temperature monitor. The life expectancy is at least 30,000 operating hours (L10, 40°C). The cooling unit is thus largely maintenance-free. All that may be required from time to time is to clean the components of the external air circuit using a vacuum cleaner or compressed air if they become visibly dirty. Any stubborn, oily stains may be removed using a non-flammable detergent, such as degreaser.

Maintenance interval: 2,000 operating hours. Depending on the level of contamination in the ambient air, the

Sequence of maintenance measures: – Check the level of dirt. – Filter soiling? Replace the filter if necessary. – Cooling membranes soiled? Clean if necessary. – Activate test mode; cooling function OK? – Check noise generation of compressor and fans.

8 Storage and disposal

Note: The cooling unit must not be subjected to

temperatures above +70°C during storage.

Store the cooling unit in the appropriate position for transport. The closed cooling cycle contains refrigerant and oil, which must be properly disposed of for the protection of the environment. Facilities for disposal are available at the Rittal plant. Please contact us for advice.
