Cleaning
Danger due to electric current
Voltage supply for fan must be interrupted and secured against restoration!
Clean the fans`s
fl
ow area.
Attention!
•
Do not use any aggressive, paint solvent cleaning agents when cleaning.
•
Make sure that no water gets inside the motor and the electronics (e.g. by direct contact with seals
or motor openings), observe protection class (IP).
•
The drain holes (if available) corresponding to the installation position must be checked for free
passage.
•
In case of improper cleaning work, no warranty is assumed regarding corrosion formation / paint
adhesion for unpainted / painted fans.
•
To avoid accumulation of moisture in the motor, the fan must be operated for at least 1 hour at 80%
to 100 % of the maximum speed before the cleaning process!
•
After the cleaning process, the fan must be operated for at least 2 hours at 80 to 100 % of the
maximum speed for drying purposes!
