4. Settings

Air-air heat exchangers are intended as complementary accessories to large industrial equipment which includea motor-operated fan or blower together with a heat exchanger module. These may also include an electricheater. The fan or blower is intended to recirculate air and allow heat exchange. The heat exchanger isdesigned for air heat transfer only. Cooling function may be controlled by an on-board or remote controller or thermostat. Heating function, wheninstalled is provided by an electrical heating element. The unit seals the cabinet which ensures that the clean airinside does not come into contact with the ambient air which may well be dirty or polluted. The unit is fit forpurpose 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 conductedaway to protect temperature-sensitive components. The characteristic graph shown in the section “Performancegraph” 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 ambienttemperature. There are natural limits to the cooling performance, dependent on the air supply temperature andthe requirement for a temperature difference of at least 5K. Unlike systems in which the heat generated isallowed to escape by air convection through ventilation slots, with the heat exchanger, the clean air inside thecontrol cabinet is prevented from mixing with the air outside, which may well be unclean.

7. MountingDanger from electrical voltageThe unit must be mounted by specialist personnel (qualified electricians). The personnel must ensure that thecabinet is disconnected from the electrical supply for the duration of the mounting operation. Therefore take thecabinet 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 preparationsSeveral points must be checked before the unit can be mounted. These checks must be made to ensure safetyand the trouble-free operation of the unit. These checks must be carried out with absolute thoroughness toensure that the unit works perfectly.

Transport damage checkOn delivery the carton containing the unit must be examined for signs of transport damage. Any transportdamage to the carton could indicate that the unit itself has been damaged in transit which in the worst casecould mean that the unit will not function.

Location and space requirementsThe location of the cabinet must allow for sufficient air circulation to and from the unit. The unit should bemounted roughly horizontally. It is therefore advisable to check that the cabinet is in a horizontal position. Themax. deviation from the vertical or horizontal should not excess 20 degrees.

SealingTo guarantee that the unit works perfectly ensure that, the control cabinet is completely sealed (to min. IP54 toEN 60529) and a good seal exists between the control cabinet and the unit. If necessary the cabinet mountingsurface should be reinforced.

9. Electrical ConnectionDanger from electrical voltageThe unit should only be connected by qualified electricians.The personnel must ensure that the unit is disconnected form the electricalsupply for the duration of connection work and is protected againstunauthorised reconnection.

Note: Check that the available voltage, frequency and fuse rating are the same as those stated on the unit datalabel.

Connection to the main electrical supplyThe 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 PhaseBlue N NeutralYellow / green Earth protectionBrown L1 PhaseGrey 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 interfaceTo avoid unnecessary run-time, the heat exchanger can be switched on and off through the door contact. Thereis 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 proceedas follows:

Take the control cabinet out of operation in the prescribed mannerSee the connection details on the circuit diagram.Note the connections of the 5-core cable from the following table.

Brown T1 Door contact 1Grey T2 Door contact 2Pink P1 Alarm high temperature NCRed P2 Alarm CommonViolet 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) mustbe 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-setin 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(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 thecabinet internal temperature.

Version No. 1-3 - 19.03.2022 Doc. No. 9951650033 10 / 14

Check that the new setting meets the requirements and if not repeat the above process. Inspect and ifnecessary replace the MCB access plate sealing tape.

11. Taking into Operation

As described before the unit is controlled in relation to the cabinet internal temperature. The required cabinettemperature can be set on the potentiometer on the controller.The temperature adjustment range is between0°C (left-hand stop) and 60°C (right-hand stop). The thermostat is pre-set at 35°C.

To adjust the cabinet internal temperature proceed as follows:

Remove the MCB access plate on the front of the unit.Using a screw driver turn the adjustment wheel on the potentiometer “TEMP” slightly to the right (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 thecabinet internal temperature.

Check that the new adjustment meets the necessary requirements. If necessary, repeat the procedure. Inspectand if necessary replace the MCB access plate sealing tape.

12. Trouble Shooting

In case of a fault logon to our website www.seifertsystems.com to locate your nearest servicing office or findyour nearest contact in the chapter “contacts” in this manual.

13. Maintenance & CleaningDanger from electrical voltageMaintenance and cleaning must be carried out by specialists (electricians). The personnel mustensure that for the duration of this work the unit and the cabinet are disconnected from theelectrical supply and protected against unauthorised reactivation.

Danger through incorrect work on the unit.The instructions in the cabinet manufacturer’s manual must be adhered to!

Damage to the unit through incorrect maintenance and repair! Maintenance and repair mustbe carried out by the manufacturer or another specialist.

Fan replacement

The rated life expectancy of the fan is L10 =30,000 hours under normal operating conditions.

To replace the internal or external fan, please proceed as following:

Remove the internal access panel by unscrewing the 10 fixing screws.Disconnect the blower cables from the connectors.Unscrew the four screws fixing the blower bracket to the cabinet.Unscrew the fan from the bracket.Re-assembly with the new blower is in reverse order.

Make sure that the blower cable length is the same as the one of the removed fan to ensure that the cable doesnot come in contact with the blower while in operation. Make sure that the correct polarity is maintained. (Referto circuit diagram). Inspect and if necessary replace the internal access panel sealing tape. In addition the unit should have regular functional tests (approx. every 2,000 hours depending on the grade ofambient pollution).
