4.4 To clean the heat exchanger
Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
Warning
• Risk of personal injury! The heat exchanger weighs about 10 kg. There is a risk that the heat exchanger
falls out of the unit.
• If the unit is ceiling mounted with side cover facing downwards, the heat exchanger may fall out if not
secured.
• Make sure that small children are not beneath the unit when the heat exchanger is removed!
Caution
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
Even if the required maintenance is carried out, dust will
build up in the exchanger block. It is therefore of vital im-
portance for the upkeep of a high efficiency that the ex-
changer 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 side cover. See chapter 4.2.
3. Disconnect the rotor power supply and the rotor sensor.
The cables are found beside the rotor at the back.
4. Take out the heat exchanger package.
5. Gently vacuum the heat exchanger.
Warning
Ensure the rotor motor is not exposed to
moisture
6. Remount the rotor. Don’t forget to reconnect the rotor
power and sensor cables.
7. Close and fasten the side cover and connect the unit to
mains.
