Servicing and maintenance

WARNING!

Touching live electrical parts will lead to electric shock.

Before any servicing and maintenance work, isolate the unit from the mains power supply and protect

against being switching on again!

WARNING!

The rotating impellers can be a hazard to fingers. Ensure all rotating parts have stopped.

– Excessive deposits of dirt, dust, grease, etc. on the impeller, motor, protection grille and, above all, between the

housing and impeller, are not permitted, as these can lead to an unbalance in the impeller, overheating of the motor

or the blocking of the impeller. In such cases, the unit must be cleaned.

– If the unit has not been used for long periods of time, maintenance must be carried out before the unit is restarted.

– If the unit has not been used in more than 2 years, the fan must be replaced.

Note the following:

• Remove deposits of dirt, e.g. on protection grille

• Conduct a visual inspection, replace damaged parts

• Freewheeling of the impeller, is impeller blocked, see Fault causes 6.3

• Vibrations – see Fault causes 6.3

• Fan unit must be inserted up to the "external grille" stop in the wall sleeve
