CLEANING AND MAINTENANCE
Always turn the fan off and take plug out of socket before cleaning or carrying out
maintenance work!
 Inspect the electrical cord, plug and the wiring for damage or discoloration. If they are
not all right, they have to be replaces/repaired by a qualified electrician.
 Check the device and any accessories regularly to ensure that they are in perfect
condition. Also check all screws and tighten them if necessary.
 Pay attention to any abnormal sounds, which may indicate damage. The potential
cause may also be imbalance. If in doubt, consult an expert.
 Keep the unit clean. Use a compressor (do not use overly high pressure, in order to
avoid damage) or vacuum to remove lint, dust etc., from motor, screens or blower
wheel. Do not use a pressure washer to clean the unit. Never open the device, not
even to remove jammed objects or stubborn dirt.
 Clean the grille and house with a (slightly humid) soft cloth. Do not use a corrosive or
abrasive cleaning agent! Dry everything properly.
 Always consult a qualified electrician or your dealer for repairs or maintenance. Ask
for original spareparts.
 Store the fan in a safe, dry place that is not subject to extremes of temperature.
Protect it against moisture and dirt, preferably in its original packaging.

damaged beyond repair. Take it to your local authority's collection point for
electrical appliances where any reusable materials will be collected and
redistributed.
