Cleaning ventilators
The ventilators must be cleaned if they are dirty. The ventilators can be easily reached
when the heat exchanger has been removed from the unit.
First push down the ventilator module
slightly. The module can then be taken out
of the unit by turning it anti-clockwise and
at the same time shifting it slightly so that
the rib on the fan housing no longer clamps
into the EPP. If the screw point on top of
the fan housing is flush with the recess
in the unit housing, the fan can be tilted.
Then disconnect both connectors from the
ventilator module. This can now be taken
out of the unit.
Then clean the fan with compressed air or a brush: do not use water. Ensure that all
dirt is removed from the impeller. Do this for both ventilators.
Caution: the small ventilator at the top of the housing and the ventilator blades must
not be damaged; this creates an imbalance and unnecessary extra noise. This also shortens
the lifespan of the fans. After cleaning, make sure that the impeller at the top of the
ventilator module is properly tightened by pressing on top of the cone shape.
Then place the fan back in the unit. First reconnect the connectors to the ventilator
module. The fan can then be replaced in the unit in the same way as it was removed.
This is made easier by aligning the screw point on top of the fan housing with the
recess in the unit.
Caution: The ventilator module is correctly in place when the rib on the fan housing
is clamped back in the slot in the EPP and the flange on top of the housing falls into
the EPP.
