Maintenance/repair

10.6.1

Replacing the bearings

By using ball bearings with „life-long lubrication", the fan is largely maintenance free. The bearings must be replaced
after the lubricant service life has expired (approx. 30,000 to 40,000 h in standard applications).
" Pay attention to unusual noises from the bearings.
WARNING
Danger from overheating!
When changing the bearings, only use original Systemair bearings with special lubrication.
»
10.6.2 Damage
" Please contact the manufacturer's customer service department in the event of any kind of damage, e.g. to the
windings.
WARNING
Danger from defective fans!
Replace any defective fans completely.
»
Repairs may only be done on the manufacturer's premises and by the manufacturer.
You can find the address on the back of these operating instructions.
