11. Cleaning
DANGER
Danger to life. Unit is powered
up.
1 Switch the mains fuse off.
1 If the impeller blades are dirty or not
running smoothly (imbalance), clean the

CAUTION
Once the overload protection
has cooled the rotating
impeller blades still represent
a danger. The ceiling fan will
automatically start back up
once the fan motor has cooled
down.
1 Do not reach into the area
around the impeller blades.
Fault Countermeasure
– Unit doesn’t run
– Thermal overload
protection of the
motor switches unit
off and back on
again after cooling
down.
Check that the mains
fuse is switched on.
If the thermal
overload protection
has tripped, the
ceiling fan must start
back up again
automatically after
1 hour at the most.
Tab.1: Fault rectification
