Reverse voltage /
M1/... F
room lighting / glow
lamp
Due to the electronics,
there is a "low-energy"
reverse voltage at
terminal 1. In order
to avoid a permanent
glow when using
a glow lamp in the
switch, a capacitor (X2
capacitor with 0.33
µF/250 V AC with wire)
can be used in parallel
with the glow lamp.
In order not to nega-
tively affect the elec-
tronics, room lighting
is to be connected via
a two-pole switch in
general.

Servicing and maintenance
Danger to life from electric shock .
An electric shock can result in death or severe injury.
u Isolate the unit from the mains power supply before working on the unit!
m The safety instructions in section 1 .2 must be observed!
− Before any work, isolate the fan from the mains power supply and protect against being switching on again!
− In principle, the units are maintenance-free, there are no user maintenance provisions. All necessary main-
tenance work must be carried out by a qualified electrician!
− Excessive deposits of dirt, dust, grease, etc. on the impeller, motor, protection guard and, above all, between
the casing 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 such cases, the unit must be cleaned.
− In cases of longer periods of standstill, maintenance must be carried out when the unit is restarted.
The following must be checked:
• Secure attachment of the fan to the subsurface / system, replace in case of doubt
• Remove contaminant deposits
• Mechanical damage, disconnect unit, replace damaged parts
• Tight fit of screw connections, do not loosen screws in the process!
• Casing quality (cracks, brittleness of the plastic)
• Free movement of the impeller, impeller does not move 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
