Maintenance, service and repair
Before maintenance, service or repair, make
sure that:
-
Power supply is interrupted (all-pole circuit
breaker).
- Fan impeller has come to a complete
standstill!
- Observe personnel safety regulations!
The fan should be cleaned when necessary, at
least 1/year to avoid imbalance an unnecessary
damage to the bearings.
If a surplus of tar is built up during combustion it
may be necessary to clean the fan more often.
The fan bearings are maintenance free and
should only be replaced if damaged.
Do not use a high-pressure cleaner (steam jet)
when cleaning the fan. Make sure the fan
impeller's balance weights are not moved or the
fan impeller distorted.
Take note of abnormal operating noise!
Check that the impeller is not hindered or the
motor protection triggered.
If the fan does not start after it has been
checked, and/or the thermal contact is reset,
contact your local supplier.
