8.2.2 FAN 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 electric motor
bearings. If you need to replace the entire unit or fan, open the door by opening the locks by turning 90°. The fan is located on rubber silent
blocks. Loosen the 4 nuts, lift and remove the fan as shown in the following figure. Keep in mind that the fan must be dynamically and statically
balanced again after removing the electric motor.
8.2.3 RECUPERATION EXCHANGER MAINTENANCE
The heat recuperation exchanger is protected by filters and can therefore only be contaminated very lightly. Nevertheless, it is recommended to
perform a visual inspection every 5 years. If necessary, open the front door by opening the locks by turning it. Remove dust from the boards with
a dry brush (
not wire!
) Or by blowing with compressed air.
