TECHNICAL DESCRIPTION , TRANSPORT
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 ro-
tate 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 mode 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 require
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.
3.2 OPERATING CONDITIONS
The standard operating temperature range of the fan is –20° C - +40° C /
+45 °C. The maximum permissible ambient temperature of the motors
is +40° C / +45 °C, see motor data.
If the fan is operated in conditions where the ambient temperature is
higher, the rated output will have to be reduced. See the instructions of
the motor manufacturer.
The fans are designed to be used as parts of equipment.
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
Motors are IEC standard IE2 or IE3 marine classified AC motors.
The motors are equipped with a thermistor and they are designed for a
frequency converter use. Admissible environmental temperature: from
–15°C up to +40° C / +45° C, see motor data..
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.

6 COMMISSIONING
6.1 SAFETY CHECKING
• Rotate the shaft and check that the impeller can move freely.
• Make sure that there are no foreign objects in the fan or in the
ducting.
• Also check that there is no unusual noise in the fan.
• Check that the installation work has been carried out in
accordance with the relevant regulations.
• All necessary protective devices must be installed.
• The fan may only be commissioned after all proper procedures
have been followed and all necessary inspections have been car-
ried out.
6.2 TEST RUN
Briefly switch on the power supply to the motor to check whether the
fan impeller rotates in the correct direction. If the impeller is rotating in
the correct direction, the fan may be switched on.
Check that no abnormal mechanical sound and no surging occurs.
MOUNTING INSTRUCTIONS, COMMISSIONING
5 MOUNTING INSTRUCTIONS
5.1 INSTALLATION OF THE FAN
The fan is to be installed to a base frame using anti-vibration
mountings. Alternatively the base could be mounted on antivibration
mountings. The base must be level and stable. The fan must only be
mounted in a horizontal plane.
5.2 FITTING THE ACCESSORIES
The fan should normally be connected to the air handling unit by
means of flexible connection or other type of a gasket to eliminate vi-
bration transfer from fan to the AHU casing.
Providing necessary grounding for the accessories is within the con-
structor’s field of responsibility.
Inlet protective screen can be fitted directly to the front frame or out-
side AHU to the inlet opening.
5.3 SAFETY REGULATIONS AND CE-MARKING
The GMMB and GPMB fan is CE-marked as a Partly Completed
Machinery and must not be put into service until the final machi nery
into which it is to be incorporated has been declared in conformity
with provisions of the Machinery Directive 2006/42/EC. Other compli-
ant directives are shown in the Declaration of Conformity.
5.4 ELECTRICAL CONNECTIONS
All electrical connections must be wired by authorised personnel only.
The necessary electrical and safety precautions must be taken into
account. If the motor is operated across a frequency converter, the
connections must be made according to the instructions of the fre-
quency converter manufacturer. The motor must be grounded.
5.5 ADDITIONAL GROUNDING
The fan can be additionally grounded to the air handling unit or base.
The grounding wire (not included in the fan delivery) is recommended
to be securely attached to the motor outer grounding point whenever it
is possible or to the marked grounding spot on motor bracket (ground-
ing bolt, nut and washers included to delivery) and the other end of the
cable to the air handling unit or base.
Additional grounding on the motor bracket, spot marked by this sticker.
For GPMB-031-with IEC 132 motor: Additional grounding in the base frame.

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.
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 an allowed
temperature, see motor table. The motor bearings have to be lubrica-
ted in accordance with the instructions that accompany the motor.
Bearings are to be replaced in accordance with the motor manufac-
turer’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 detergent or a solvent.
The cleaning is to be done at least once a year. Badly tarnished impel-
ler will result in lower efficiency of the fan and increases energy con-
sumption.
MAINTENANCE
7.3 REPLACING THE MOTOR AND THE IMPELLER
The fan must be disconnected and taken out from the unit before the
motor can be replaced.
1. Dismantle the front plate supports (GMMB size 056 and bigger,
motor IEC 112 or smaller; GPMB all sizes) and the front plate and
inlet cone (front plate and inlet cone are permanently riveted to
each other).
or
1. Detach the triangular front plate supports (GMMB with motor IEC
132 and bigger) from the front plate (remove entirely if needed) and
remove the front plate and inlet cone (front plate and inlet cone are
permanently riveted to each other).

3. If needed, use an extraction tool to pull the impeller off the motor
shaft. There is a groove in the impeller hub for the extraction tool.
With bigger sizes it is recommended to support the impeller.
Size of the extraction tool needed depends on the impeller size.
Please follow the general instructions of the extraction tool care-
fully.
7. Mount the impeller on the motor shaft.
8. Mark the needed overlap to the inlet cone, see the below
illustration and table.

9. Mount the front plate and inlet cone (permanently riveted to each
other).
10. Mount the front plate supports (when applicable).
11. Align the impeller and check that the gap between the impeller and
the inlet cone is as equal as possible around the impeller. Also
check that the overlap is correct.
12. Tighten the motor fixing bolts, reassemble and tighten the end bolt
and washer, tighten the clamp screw.
Before installing and starting the fan, make sure that there is no me-
chanical contact between the impeller and the inlet cone.
7.4 FINAL INSPECTION
Check that:
• The impeller is mounted for the correct direction of rotation.
• All screws and nuts have been tightened.
• No foreign objects have been left in the fan or in the ducting.
OVERLAP
4. Dismantle the old motor from the motor bracket.

11. AIR FLOW MEASUREMENT DEVICE
The airflow sensor is used for measuring the airflow of the plug fans.
The method is based on differential pressure. The pressure is meas-
ured at a specific point in the inlet cone and the reference pressure is
measured upstream of the inlet cone. The air flow sensor is supplied
factory mounted in the inlet cone. The air flow is calculated as a func-
tion of the coefficient k and the differential manometer reading Dp
m
from the equation:
