4. Settings
The cooling unit is intended to be used as a complementary accessory to larger industrial equipment. The unit
is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to
protect heat sensitive components. It is not intended for household use.
The unit has two completely separate air circuits which ensure that the clean cabinet air does not come into
contact with the ambient air which may well be dirty or polluted.
Enclosure cooling units can dissipate large quantities of heat from sealed enclosures such as electrical
enclosures into the ambient air and at the same time reduce the cabinet internal temperature to below that of
the ambient air.
The unit can function without problems in extreme ambient conditions (e.g. dusty and oily air) with a standard
operating temperature ranging between +10°C (50°F) and +60°C (131°F). Units can be ordered with an
additional electrical cabinet heater. For the cooling capacities and evironmental ratings please refer to the type
plate data.

Version Nr. 1-11 - 05.10.2022 Doc. No. 9985409576 5 / 24
5. Functional principle
The cooling unit for industrial enclosures works on the basis of a refrigeration circuit consisting of four main
components; a compressor, an evaporator, a condenser and an expansion device. The circuit is hermetically
sealed and R134a refrigerant circulates inside it (R134a is chlorine free and has an Ozone Destruction Potential
[ODP] of 0 and a Global Warming Potential [GWP] of 1430).
The compressor compresses the refrigerant (thus taking it to high pressure and high temperature), and pushes
it through the condenser, where it is cooled by ambient air thus passing from the gas to the liquid state. At the
liquid state it then passes through the capillary pipe being a much lower pressure the refrigerant arrives to the
evaporator where it absorbs the necessary heat to change from liquid to gas state. The gas is then drawn back
into the compressor completing the cycle.

8. Mounting
The power supply rating on unit rating plate must comply with mains rating.
Always disconnect the power supply before opening the unit.
The heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any
condition. At cooling unit selection always cater for a safety margin of at least 15% extra cooling output in the
worst conditions.
Air inlets and outlets must be completely free from obstruction. Ensure that flows of air leaving and entering the
cooling unit, internal and external, are not obstructed. It must also be ensured in accordance with UL, that the
air outlet is not blowing air directly at an equipment operator. Should this be the case a barrier or duct shall be
provided to redirect the airflow.
Cooling unit enclosure air suction hole must be installed in the highest possible point.. When installing the unit
on a door ensure it can take the weight.
Before drilling the enclosure ensure the fixing elements and couplings will not interfere with the equipment
inside the enclosure itself. Disconnect power before starting any work inside the enclosure.
If the unit is mounted in a recessed position, the controller bracket can be pulled according to the wall thickness
of the enclosure outwards as per steps below.

Applying supplied tight tape
Condensate management:
High humidity and low temperatures inside the enclosure can lead to condensation on the evaporator.
Condensate that flows back into the enclosure can damage sensitive control electronics. The integrated
condensate evaporation of the cooling unit releases the condensate to the environment. If condensate
formation is too great, additional condensate can drip into an overflow trough, which then drains off on the
ambientt side.In order to prevent the formation of excessive condensate, you should nevertheless:
- check the seals at regular intervals
- consider installing a door contact switch (order no. 3100001). This can prevent condensation forming
when enclosure door is left open.

11. Electrical connection
Caution, risk of death
Unconnected and / or faulty protective conductor systems can lead to dangerous voltages and electric shocks
which can cause serious accidents.
Work on electrical connections may only be carried out by trained electrical engineers.
Door Switch
The unit can be switched ON and OFF via a door contact switch. When delivered the door contact terminals are
bridged on the female connector. To connect the door contact switch remove the bridge and connect door
contact switch. The contact must be closed when the cabinet door is closed.
It is possible to change the logic of the door switch (controller firmware rev. 1.2 or higher). This can be set by
changing the value of parameter c68. Refer to the table below and section Controller: Setting temperature units
(°C / °F), low temperature alarm, door contact logic section for more information.
c68 = 0 (default) ON if closed - Door contact terminals bridged, or NC door switch connected
(contact must be closed when cabinet door is closed)
c68 = 1 ON if open - Remove bridge, or NO door switch connected
(contact must be open when cabinet door is closed)
Alarm Contacts
Alarm contacts rated according to:
EN60730-1 8(4)A N.O., 6(4)A N.C., 2(2)A N.O./ N.C. @ 250Vac 100000 cycles
UL 873 8A resistive 2FLA 12LRA, pilot duty C300 @ 250Vac 30000 cycles
These contacts are not suitable for fluorescent loads (neon lights, etc.) that use starters (ballasts) with phase
shifting capacitors. Fluorescent lamps with electronic controllers or without phase shifting capacitors can be
used, depending on the operating limits specified for each type of relay.
SCCR
Refer to UL508A Supplement SB and Seifert Systems’ document Short Circuit Current Rating (SCCR) on methods
how to modify the available short circuit current within a circuit in the panel.

14. Taking into operation
Attention!
The unit can be damaged by lack of lubricant. To ensure that the compressor is adequately lubricated the oil,
which has been displaced during transport, must be allowed to flow back into it. The unit must therefore be
allowed to stand for at least 30 min. before being connected to the mains and taken into operation.
The unit / system must be protected with a MCB Type D or K. Upon connection the internal fan will start
working. If the temperature inside the enclosure is higher than the set value of the controller both the
compressor and external air fan start working. The cooling cycle will either stop once the air inside the
enclosure reaches the set temperature minus hysteresis or once the minimum On-time is reached.
The hysteresis is 3K, the minimum ON-time is 4 minutes, the minimum OFF-time is 3 minutes, for units with a
cooling capacity of more than 1 kW is it usually 7 minutes.
The setpoint for the internal enclosure temperature is pre-set at 95°F.
