CLEANING THE FANS (INSTALLER)

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 resistance support (figure 4).

7.   Remove the additional and post-heating radiator support, which 

is attached by two wing nuts (Vallox 110 MV and Vallox 145 MV) or 

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

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.
