4.4 LIFTING OF THE FAN
4.4.1 SIZES ≤071
The fan is to be lifted with three lifting chains/beams (one
attached to the front plate and two to the rear end of the fan).
There are three alternative places to attach the rear lifting hooks,
which are to be used depending on the fan combination.
Wherever possible, use holes on the motor bracket as shown in
the picture below.
In case of a built-on frequency converter, if there is no access to
the hole on the motor bracket behind the frequency converter
assembly bracket, one of the rear chains/beams could be
attached to the hole on the frequency converter assembly bracket
(up to fan size 045).
With bigger fans (or if there are no holes on the motor bracket)
holes on the base frame are to be used. In this case it must be
taken into account not to damage the frequency converter.
Transverse beam must be used if needed.
Beware of damaging the fan while lifting. Always adjust chains/
beams long enough not to get in touch with motor, frequency
converter or impeller.

7. MAINTENANCE
7.1 WARRANTY
A precondition of the warranty is that regular maintenance has
been carried out. Defects under warranty must immediately be
notified to the manufacturer or the importer. The warranty does
not cover service work or indirect damages.
7.2 MAINTENANCE
7.2.1 BEFORE MAINTENANCE
Switch off the power supply to the fan at the safety switch and
wait until the impeller is fully stopped.
THERE IS A RISK OF ELECTRIC SHOCK ON PM-
MOTORS IF THE IMPELLER IS ROTATING.
ENSURE THAT THE IMPELLER IS SURELY STILL
BEFORE AND DURING THE MAINTENANCE WORK.
7.2.2 INSPECTION
The fan is to be inspected at least once a year.
7.2.3 CHECKING THE MOTOR BEARINGS
The motors are meant to be operated in dry or humid air at a
normal ambient temperature. The motor bearings have to be lu-
bricated in accordance with the instructions that accompany the
motor. Bearings are to be replaced in accordance with the motor
manufacturer’s instructions.
7.2.4 IMPELLER
The maximum permissible vibration level measured from the
motor bearing is 4.5mm/s RMS. The impeller can be cleaned by
using a vacuum cleaner, compressed air or by brushing. If the
impeller is coated with greasy dirt it can be washed with a deter-
gent or a solvent.
The cleaning is to be done at least once a year. Badly tarnished
impeller will result in lower efficiency of the fan and increases en-
ergy consumption.
