Cleaning and Maintenance

All work may only be carried out by a qualified person. All relevant safety regulation, national standards and
norms are to be adhered to!
Make sure before the cleaning that the unit is isolated from the mains and is secured against restarting
with an isolator switch!
- Impeller must stand still
– Clean unit only with a damp cloth.
– Excessive deposit of dirt, dust, grease and other materials on the impeller, motor and between casing and impeller is
to be avoided and has to be prevented by periodical cleaning.
– For maintenance purposes inspection doors and access openings must be provided in the duct system in a suitable
place.
– The motors have maintenance-free, long lasting, greased ball bearings.
6.0 Indications – Disturbance origins
Triggering of motor overheat protection (TK) can indicate:
– fan does not run on highest speed
– fan runs permanetly on highest speed
– build- up of dirt, hard running impeller and/or ball bearing failure
– too high air flow temperature
Abnormal noises can mean
– wrong direction of rotation
– worn out ball bearings
– bad vibration isolation to other buildings and ducting systems
Vibration can originate from
– unbalanced or dirty impellers
– insufficient vibration isolation from buildings and ducting systems
Extreme reductions in performance can occur
– with wrong direction of rotation
– if resistance to air stream through ducting and accessories (grilles, shutters, filters etc.) is higher than designed
