Even if the required maintenance is carried out, dust will build up in the exchanger block. It is therefore of vital impor-
tance for the upkeep of a high efficiency that the exchanger block is removed from the unit and cleaned periodically as
described below. Clean the heat exchanger at least every 3 years or when required.
1. Stop the unit by disconnecting the mains.
2. Open the front hatch. See chapter 6.2.
3. Disconnect the heat exchanger power supply and the rotor sensor. Both cables are found beside the heat exchanger.
4.
Warning
Risk of personal injury! The heat exchanger weighs about 14 kg. There is a risk that the heat exchanger
falls out of the unit.
Pull out the heat exchanger towards you. Some force may be needed.
5. Clean the rotor.
Wash in hot soapy water. Do not use detergent containing ammonia. Rinse using, for instance, a shower handle or
carefully with compressed air.
Warning
Ensure the rotor motor is not exposed to moisture
6. Remount the heat exchanger. Don’t forget to reconnect the heat exchanger power and sensor cables.
7. Close and lock the front hatch and connect the unit to mains.
