Fans
Check the cleanliness of the fans when carrying out maintenance for fi lters and the heat recovery
cell. Clean the fans if needed. The fans are very sensitive to external mechanical damage, and
it is recommended to clean them in place.
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.
Cleaning supply air fan (T)
Remove the extract air fi lter (C), upper support for the HR cell (E) and the HR cell (D) from the
unit as instructed earlier. Pull the temperature sensor off from the upper part of the extract air duct
(G) (fi gure 1) and then remove the stopper screw from the lower edge of the duct. After that the
extract air duct comes out by turning and simultaneously pushing downwards (fi gures 2 and
3).Detach the temperature sensor from the resistor support (fi gure 4).Then detach the support of
the additional and post-heating resistors (H), fastened with two butterfl y nuts from downward
(fi gure 5). Then pull the resistors and the support from the unit and disconnect the quick coupling
of the resistor conductors. The fan can now be cleaned in place. If you wish to detach the fan,
lift it upwards and crank the plastic lock to the right using for instance a chisel (fi gure 6).The
fan then falls down and can be pulled out of the unit. Disconnect the quick coupling of the fan
conductors. When needed, detach the intermediate shaft of the bypass damper from the end of
the partition wall (fi gure 7).

Cleaning extract air fan (P)
Remove the extract air fi lter (C), upper support for the HR cell (E) and the HR cell (D) from
the unit as instructed earlier. Remove the supply air fi lters G4 and F7.Open the four screws
(F, fi gure 8) on the protective cover of the extract air fan and remove the cover downwards.
The extract air fan can now be cleaned in place (fi gure 9). If you wish to detach the fan, lift
it upwards and crank the plastic lock to the right using for instance a chisel (fi gure 6).The fan
falls down and can be pulled out of the unit (fi gure 10). Disconnect the quick coupling of the
fan conductors.

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 fl ow out from the ventilation
unit without hindrance. When carrying out maintenance, for instance in autumn before the
beginning of the heating season, make sure that the condensing water outlet in the bottom tank
is not clogged. You can check it by pouring a little water in the tank. Clean if needed. Do not
let water fl ow into electrical devices.
