3. TECHNICAL DESCRIPTION
The fan is used to generate a desired air volume at a given
pressure rise that corresponds to the pressure losses in the duct
system to which the fan is connected, and internal losses inside
of the Air Handling Unit.
The plug fan is intended to be used inside of the Air Handling Unit.

3.2 OPERATING CONDITIONS
The standard operating temperature range of the fan is –20° C +40° C. The maximum permissible ambient temperature of the
motors is +40° C.
If they are operated in conditions where the ambient temperature
is higher, the rated output will as a rule have to be reduced. See
the instructions of the motor manufacturer.
The fans are designed to be used as parts of equip
ment. They are not ready for use as a stand-alone
product and the standard version does not have
protection against body contact, the appropriate
protective measures are to be taken according to
EN 292/294.
Only operate the fan up to the maximum permissible speed given
in the information on the fan rating plate.
-
3.3 MOTORS
Both AC- and PM-motors can be used with GMPM and GMEB plug
fans.
AC-motors are IEC-standard IE2 or IE3 motors. The motors are
equipped with a thermistor and they are designed for a frequen
cy converter use. Admissible environmental temperature: from
–15°C up to +40° C.
PM-motors are high efficiency IE4 permanent magnet motors.
They shall be used together with a frequency converter and can
not be connected directly to the mains. Admissible environmental
temperature: from –15° C up to + 40° C.

3.4. FREQUENCY CONVERTERS
All fans used in an Air Handling Unit in the European Union area
shall be equipped with a speed controller in accordance with the
Regulation 1253/2014.

4 TRANSPORT
4.1 TRANSPORT INSPECTION
Check the fan immediately after you receive it and make sure that
it has not been damaged during transport. If you discover any
damage, get in touch with the transportation company without
delay. Briefly rotate the fan impeller to see that it rotates easily.
Check the information on the fan rating plate.
Proper procedures must be followed when transporting the product!
Faulty conditions in transporting may result in serious damage on
the product
4.2 TRANSPORT SAFETY
The transport material is to be selected according to the packaging and the weight of the product. Loading must be carried out
as instructed.
4.3 INTERMEDIATE STORAGE
If the fan is to be stored before or in between uses, the following
needs to be taken in account:
– Original packaging is to be used. If the storage conditions re
quire it, additional protection may be added
– The storage environment must be dry, dust-free and not have
a high level of humidity (<70%)
– Storage temperature must be in between –25° C and +40° C
Before commissioning, the respective instructions must be
studied thoroughly.
-
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.
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).
FläktGroup DC_9853GB_20180425_R0
Beware of damaging the fan while lifting. Always adjust chains/
beams long enough not to get in touch with motor, frequency
converter or impeller.
