7) and remove the quick connector of the radiator wires.
WARNING
Before removing the resistor from the unit, make sure it is not hot.

that the fans be cleaned in place, i.e. without attempting to
remove them.
10. To remove the fan for cleaning, proceed as follows.
a. If necessary, remove the arm pins. Use pliers to press the
pins straight, so that they are easier to install back later.
b. Push the fan gently upwards (figure 9).
c. Pry the plastic lock to the right of the fan with a
screwdriver, for example (figure 10).
d. The fan falls downwards.
e. Pull the fan out of the unit (figure 11).

fan has now been removed for cleaning.
11. To reassemble the ventilation unit, follow the above steps in
reverse order.
TIP
When you re-install the temperature sensor, install it with the tip
upward in such a way that it does not get squeezed between the
bypass plate, and that it does not lean against the radiator frame.
12. Close the door and plug the unit back into the mains.
13. The fan has now been checked and cleaned.
