Maintenance
The fans are easily taken out from the unit (figure 7) by loosening 4 screws and disconnecting the fast couplings to the
electric wires. Depending on the accessories installed, remove the tubing next to the fast couplings for the extract air
fan or both the extract air fan and supply air fan.
Clean the fans with a cloth or a soft brush with a recommended interval of once per year. Do not use water. White spirit
can be used to remove obstinate settlements. Allow drying properly before remounting.

5.3.5 Checking the Hot water heating battery
After long periods of operation (usually several years) dust may have deposited on the surface of the battery. This may
reduce batteries capacity. The battery can be cleaned with a pressure washer with misting jets, or with compressed air.
Cleaning should be carried out carefully so as not to damage the batteries aluminium fins. Once a year the battery
water circuit needs to be vented to maintain the batteries capacity.
5.3.6 Checking the Electrical heating battery
After long period of time dust and pollutants can build up on the heating rods. This can cause unpleasant odors and in
the worst case fire. Clean with compressed air, vacuum or brush. The automatic safety function needs to be tested and
verified.
