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
• 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 impor-
tance for the upkeep of a high efficiency that the exchanger block is removed from the unit and cleaned periodically as
illustrated below. Clean the heat exchanger at least every 3 years or when required.
1. Stop the unit by disconnecting the mains.
2. Open and remove the side cover. See figure 4.2.
3. Disconnect the rotor power supply and the rotor sensor.
Both cables are found beside the rotor.
4. Pull out the rotor towards you. Some force may be
needed.
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.
