To remove the filters from the interior of the unit, it is possible to use a tool that is stored inside the unit at the filter frame. The device can be
manipulated with the filter insert by hooking behind the plastic frame of the filter.
8.2.2 FAN REPLACEMENT AND MAINTENANCE
The fans are protected by filters and can therefore only be slightly soiled. Nevertheless, it is recommended to perform a visual inspection every
5 years. Remove dust from the impeller with a dry (not wire!) Brush or by blowing with compressed air. Check the condition of the bearings
of electric motor (estimated bearing life is 40000 h). If the entire unit or fan needs to be replaced, open the unit door. The fan is located on rubber
silent blocks. Loosen the 4 nuts on the vertical partition and the 2 nuts on the silent blocks under the fan motor, lift and remove the fan, including
the motor and frame. To access the secondary fan, it is necessary to remove the service wall inside the unit.
Keep in mind that the fan must be
dynamically and statically balanced again after removing the electric motor.
