MAINTENANCE INSTRUCTIONS
3.3. Fans
Check the cleanliness of the fans in connection with the maintenance of
the filter and the heat recovery cell. Clean the fans if necessary. You can
remove the fans from the unit before cleaning them.
The fan blades can be cleaned with compressed air or with a brush. Do
not remove or move the balancing pieces on the fan blade.
Removing supply and extract air fan
Before removing the supply and extract air fan, the filters of the unit and
the HR cell have to be detached as explained earlier. After that the
electrical quick connectors (1) of the fan assembly have to be unfastened.
The fan assembly can then be tilted sidewards (2) and pulled out through
the maintenance door (3).
3.4. Condensing water
During the heating season, humidity of extract air condenses into
condensing water. Water formation may be abundant in new buildings
or if ventilation is low compared to the humidity build-up caused by the
residents. Condensing water needs to flow out from the ventilation unit
without hindrance. When carrying out maintenance operations, for
instance in autumn before the beginning of the heating season, make
sure that the condensing water outlet (L) behind the bottom tank on the
exhaust air side is not clogged. You may check it by pouring a little water
in the tank. Clean if necessary. Do not let water flow into electrical
devices.
