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.
To clean the fan:

1.  Disconnect the ventilation unit from the mains electricity 

supply.

2.  Open the door of the Vallox ventilation unit by undoing the 

finger screws.

3.  Lift the door off. 

CAUTION

The door is heavy.

4.  Remove the supply air filters (A) and the extract air filter 

and turn the upper support of the cell (B) anti-clockwise 

against the ceiling. See chapters “Replacing the filters” and 

“Cleaning the heat recovery cell”.

5.  Remove the support plate (F) by undoing the screws (E).

6.  Push the wires of the fan and the rubber feedthrough (K/L) 

through the intermediate floor and to the bottom part of the 

unit.

7.  Remove the plastic screws used to fasten the fans (I) (2 per 

fan). Remove the wing screws (J) (2 pcs) of the post-heating 

resistor (only when changing the supply air fan) and remove 

the cable of the resistor (G) from the connector.

8.  Remove the fan from the unit by lowering it before turning 

the fan anti-clockwise, whilst tilting it. Remove the control 

grille by undoing the screws (4 pcs).

9.  You can now clean the fan. Put the control grille (S) back in 

place after cleaning.

10.  Reassemble in reverse order after cleaning. Once the fan 

has been installed, ensure that the rubber feedthroughs (M, 

K, L) are in place.

11.  Close the door. Ensure that the safety switch catch of the 

door is touching the safety switch.

12.  Plug the ventilation unit back into the mains. 

 

The fan has now been checked and cleaned.

If the power cord is damaged, it must be replaced by the 

manufacturer, its service agent, or a similarly qualified person in 

order to avoid a hazard.
