MAINTENANCE
CUT OFF POWER SUPPLY BEFORE ANY OPERATIONS ARE PERFORMED.
Technical maintenance means regular cleaning of the unit surfaces of dust. Use a soft brush or compressed air to remove dust.
Clean the impeller blades at least every 6 months.
Installation of an air filter prolongs the interval between the cleaning, to perform the cleaning first remove the screws and the fan cover.
Wipe the impeller blades with a cloth wetted in a mild detergent solution. Avoid water dripping on the electric motor!
After cleaning of the impeller install the cover and tighten the screws.
