CLEANING THE FANS

Check the cleanliness of the fans when servicing the filters and 

the heat recovery cell. Clean the fans as required.
You can clean the fan blades with compressed air (wear protective 

goggles) or by brushing them gently. Do not remove or move the 

fan blade balancing weights.

Cleaning the supply air fan

To clean the supply air fan:

1.  Disconnect the ventilation unit from the mains electricity 

supply.

2.   Lift the latch to open the door of the Vallox ventilation unit.

3.   Lift the door off. 

CAUTION

The door is heavy.

4.   Remove the extract air filter (C), the cell top bracket (E) and the 

heat recovery cell (D). See chapters “Replacing the filters” and 

“Cleaning the heat recovery cell”.

5.  Pull out the temperature sensor (figure 1) located at the top 

of the extract air duct (G). Remove the stopper screw (I) at the 

bottom of the duct. The extract air duct now comes out by 

turning and pushing it downwards simultaneously (figure 2).

6.  Remove the temperature sensor from the resistor support 

(figure 4).

7.  Remove the additional and post-heating resistor support, 

which is attached by two wing nuts (Vallox 110 MV and Vallox 

145 MV) or screws (Vallox 096 MV) from below (figure 5). 

MAINTENANCE

IMPORTANT

The fans are 

extremely sensitive 

to external shocks. It 

is recommended that 

the fans be cleaned 

in place, i.e. without 

attempting to remove 

them.
Handle the fan blades 

carefully. Do not 

remove or move the 

fan blade balancing 

weights.
