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.

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.

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

from the equation:

= air ﬂow m

k = k-factor of each fan

= differential pressure reading (Pa)
