The unit has to be operated according to the type plate and the wiring diagram, and must be protected
externally from overloading and electrical faults via suitable protective devices.
Danger through incorrect work on the unit
The unit can only be installed and maintained by technical competent and qualified
personnel, using only supplied material according to the supplied instructions.
Danger from electrical voltage
Only specialised personnel are allowed to maintain and clean the unit. The personnel must
ensure that for the duration of the maintenance and cleaning, the unit is disconnected from
the electrical supply.

4. Technical functions
Air-air heat exchangers are intended as complementary accessories to large industrial equipment which include
a motor-operated fan or blower together with a heat exchanger module. These may also include an electric
heater. The fan or blower is intended to recirculate air and allow heat exchange. The heat exchanger is
designed for air heat transfer only.
Cooling function may be controlled by an on-board or remote controller or thermostat. Heating function, when
installed is provided by an electrical heating element. The unit seals the cabinet which ensures that the clean air
inside does not come into contact with the ambient air which may well be dirty or polluted. The unit is fit for
purpose within the rated/declared ambient conditions (e.g. dusty and oily air or high air temperatures between
-5°C and 55°C), also indicating the rated allowable ingress and environment.
Heat exchangers are used where the heat generated by energy losses in control cabinets must be conducted
away to protect temperature-sensitive components. The characteristic graph shown in the section “Performance
graph” applies to external (ambient) air as the coolant.
In air-to-air heat exchangers, the internal temperature of the control cabinet cannot be cooler than the ambient
temperature. There are natural limits to the cooling performance, dependent on the air supply temperature and
the requirement for a temperature difference of at least 5K. Unlike systems in which the heat generated is
allowed to escape by air convection through ventilation slots, with the heat exchanger, the clean air inside the
control cabinet is prevented from mixing with the air outside, which may well be unclean.

7. Mounting
Danger from electrical voltage
The unit must be mounted by specialist personnel (qualified electricians). The personnel must ensure that the
cabinet is disconnected from the electrical supply for the duration of the mounting operation. Therefore take the
cabinet out of operation, following the relevant instructions before mounting work commences.
Danger through incorrect work on the unit. Only specialists are allowed to put the unit into operation.
Mounting preparations
Several points must be checked before the unit can be mounted. These checks must be made to ensure safety
and the trouble-free operation of the unit. These checks must be carried out with absolute thoroughness to
ensure that the unit works perfectly.
Transport damage check
On delivery the carton containing the unit must be examined for signs of transport damage. Any transport
damage to the carton could indicate that the unit itself has been damaged in transit which in the worst case
could mean that the unit will not function.
Location and space requirements
The location of the cabinet must allow for sufficient air circulation to and from the unit. The unit should be
mounted roughly horizontally. It is therefore advisable to check that the cabinet is in a horizontal position. The
max. deviation from the vertical or horizontal should not excess 20 degrees.
Sealing
To guarantee that the unit works perfectly ensure that, the control cabinet is completely sealed (to min. IP54 to
EN 60529) and a good seal exists between the control cabinet and the unit. If necessary the cabinet mounting
surface should be reinforced.

10. Electrical connection
Danger from electrical voltage
The unit should only be connected by qualified electricians.
The personnel must ensure that the unit is disconnected form the
electrical supply for the duration of connection work and is protected
against unauthorised reconnection.
Note: Check that the available voltage, frequency and fuse rating are the same as those stated on the unit data
label.
Connection to the main electrical supply
The mains connection is made via a 5-core cable. To connect the unit to the mains proceed as follows:
Take the control cabinet out of operation in the prescribed manner.
See the connection details on the circuit diagram.
Note the connections of the 5-core cable from the following table.
Black L Phase
Blue N Neutral
Yellow / green Earth protection
Brown L1 Phase
Grey N1 Neutral
Note: Connect the unit to the mains. Take the control cabinet back into operation in the prescribed manner.
Power consumption and start-up current are stated on the data label and under technical data.
Connecting the alarm and door contact interface
To avoid unnecessary run-time, the heat exchanger can be switched on and off through the door contact. There
is also an alarm contact that notifies about high cabinet temperature and about fan-failure.
The alarm/door contact interface is made via a 5-core cable. To connect the alarm/operation interface proceed
as follows:
Take the control cabinet out of operation in the prescribed manner
See the connection details on the circuit diagram.
Note the connections of the 5-core cable from the following table.
Brown T1 Door contact 1
Grey T2 Door contact 2
Pink P1 Alarm high temperature NC
Red P2 Alarm Common
Violet P3 Alarm high temperature NO
Attention: The door contact (T1, T2) must be switched potential-free.
Attention: The current that will operate the alarm contact (P1, P2, P3)
must be less than 0,5 A / 24VAC or 0,5 A / 24VDC.
The temperature adjustment range for the alarm temperature is
between 40°C (left-hand stop) and 70°C (right-hand stop). The alarm
temperature is pre-set in our works at 60°C.
To change the setting for the alarm temperature:
Remove the MCB access plate on the front of the unit.
Using a screwdriver turn the adjustment wheel on the potentiometer “ALARM” slightly to the right
Version Nr. 1-1 - 05.03.2020 Doc. Nr. 9951650033 10 / 14
(higher) or to the left (lower).
Please note that the setting for the alarm signal should be at least 5 - 10°C higher than the setting for the
cabinet internal temperature.
Check that the new setting meets the requirements and if not repeat the above process. Inspect and if
necessary replace the MCB access plate sealing tape.
