Remove the 2 connection cables to the fan from the terminals -X01/0 and -X01/1 in the low-
voltage compartment in order to interrupt the voltage supply of the fan.
Reach through the front opening of the fan box.
Turn the fan blades manually.
The smooth operation of the fan blades is proven when the fan blades do not get blocked during
rotation and do not scrape the fan box.
In case of sluggishness of the fan blades, repeat the installation of the fan until smooth operation
is achieved.
After successful test of the fan blades, connect the cables to the terminals -X01/0 and -X01/1 in
the low-voltage compartment.
