Servicing and maintenance

m
DANGER!
When dismantling, live parts which may result in electric shock upon contact may be exposed.
Before dismantling, isolate the fan from the mains power supply and secure against being switched on again!
– The units are basically maintenance-free, there is no provision for user-maintenance. Nevertheless, all necessary
maintenance work must be carried out by trained electricians!
– Excessive deposits of dirt, dust, grease, etc. on the impeller, motor, protection guard and, above all, between the
housing and the 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 cases of longer periods of standstill, maintenance must be carried out when the unit is restarted.
The following must be checked:
• Secure mounting of the fan to the subsurface / system, replace in case of doubt
• Remove contaminant deposits
• Mechanical damage, decommission unit, replace damaged parts
• Tightness of screw connections, do not loosen screws in the process!
• Housing surface coating (e.g. rust, paint defects)
• Freewheeling of the impeller -> Is the impeller not running freely- see Fault causes 8.1
• Bearing noises
• Vibrations– see Fault causes 8.1
• Power consumption according to type plate - see Fault causes 8.1
