1. Disconnect the ventilation unit from the mains electricity supply.
2. Open the doors of the unit.
3. Pull the temperature sensor out of the rubber feed through (A).
4. Disconnect the quick connector (B) of the fan cables.
5. Remove the rubber feed through (C).
6. Undo the fan’s mounting screws.
7. Pull the fan out of its housing.
8. Clean the fan.
9. To reassemble the ventilation unit, follow the above steps in
reverse order.
10. Close the doors. Ensure that the safety switch catch of the door
is touching the safety switch.
11. Plug the ventilation unit back into the mains.
The fan has now been checked and cleaned.
Clean the extract air fan in the same way. The extract air fan is
located symmetrically on the opposite side of the unit.
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.
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.
NOTE
Remember to replace the
temperature sensor by feeding
it through the rubber feed.
