Installation Manual
4.0 INSTALLATION
Installation must be completed by competent persons, in accordance
with good industry practice and should conform to all governing and
statutory bodies regulations i.e. IEE, CIBSE, etc. and EN standards etc.
Before commencing installation check that all material, including
mounting feet and optional ancillaries are available to complete the
work. Every unit is tested and serialised at works and a test certificate
produced, the details are also recorded on the fan side rating plate
which should also be referred to before handling and installation. Any
damage or deviations should be immediately reported to the seller/
supplier/agent quoting the order and rating plate details.
Ensure that there is adequate clearance for the removal of the
motor/fan assembly for maintenance purposes.
The list below states the main characteristics of the SQUIF fan range
certified for operation at 400°c for 2 hours. The unit:
•Is thermally uninsulated.
•Only suitable for non-smoke reservoir applications.
•Is dual purpose i.e. suitable for day-to-day operation and one-off
emergency use.
•Suitable for mounting in horizontal and vertical orientation only.
4.1 Mechanical Installation
Fans are suitable for both internal and external installation and whilst
they can be installed in either the recommended vertical (installation
type A) or alternative horizontal (installation type B) attitude, the
standard brackets provided are suitable only for the more conventional
vertical (A) mounting position.
Where silencers are to be fitted to the unit (for all sizes except
SQF41), installation type A should be used to ensure silencer
splitters are vertically orientated (Figure 2). SQF41 silencers are
square and can be rotated to ensure vertical orientation in either
installation type.
For horizontal (B) mounting (Figure 3), observe the centre of gravity
(approximately 100 - 150mm left of flange) and fit an angle bracket
or unistrut steel bar (not supplied) to brace the unit. Fit AV mounts
equidistant of CG line and at a safe distance so as to level unit.
Rotate the fan impeller by hand to ensure free and smooth rotation and
that no handling or transit damage has occurred, observe the direction
of flow/direction of rotation arrow and ensure that:
•All optional accessories such as support brackets, attenuators,
guards, flexible connectors etc. are assembled to the fan.
•Support brackets are fitted appropriate for the installed attitude -
vertical or horizontal.
•When offering the fan to the ducted system that both inlet and
outlet connections are perfectly aligned.
It is advisable to fit flexible connectors on either side of the fan
unless there is an open-ended inlet or discharge and the fan should
be supported on Anti-Vibration mounts (A.V.'s). The A.V.'s should be
levelled off to maximise isolation and the flexible connectors correctly
aligned with the fan at the correct tension.
A.V. mounts isolate the fan only. Silencers / backdraught dampers
and other "significant mass" accessories should form part of the
fixed ductwork after the flexible connection.

4.2 Electrical Installation
Units are not supplied with electrical isolators, their selection and
provision is the responsibility of the installer.
When the unit is operated in emergency mode smoke extract
operation - all controls must be bypassed.
Ensure the electrical supply is suitable for the fan and that all the wiring,
fuses and overload protection etc. is appropriately sized by comparing
with the rating plate.
Electrical connection is made direct to the motor on all three phase
fans and to a termination box on single phase fans. Where a starter,
speed control, frequency inverter or Ecosmart control is used also refer
to the control installation manual.
It is essential to note that for all three phase motors of 4kW and above
the final connection must be DELTA and:
•If a star/delta starter is to be used connect the six motor
terminals directly to the starter.
•If a frequency inverter or Ecosmart speed control is to be used
connect in DELTA.
•If the fan is to be started direct on line (D.O.L) connect the
motor in DELTA.
4.3 Electrical installation - Motors
Motors are totally enclosed and protected to IP55 (Dust and low
pressure water jets).
Please note the requirements for maintenance of the motor. Failure to
comply with regulations will invalidate any warranty claim.

5.0 SPECIFIC COMMISSIONING AND SERVICING
REQUIREMENTS
400°C for 2 hours Units for Smoke Extract
Exposure temperature/time: 400°C for 2 hours
These units are used to provide a SAFETY FUNCTION for people
in the event of fire in public premises or in the home: they are
therefore subject to strict constraints concerning their operating and
maintenance.
Operating Constraints
i. Check on the nameplate that the selected unit corresponds to the
maximum exposure temperature and duration.
ii. Non ventilated motors MUST be placed in the airflow from the driven
fan. Ventilated motors can be placed outside the flow.
iii. AFTER THE UNIT HAS BEEN SUBJECTED TO ONE EMERGENCY
DUTY OPERATION, IT MUST BE REPLACED.
iv. With variable speed control. Ensure that the maximum speed never
exceeds the speed of the motor supplied by the mains and that the
delivered power corresponds to the previous definitions. The unit
should be equipped with PTC thermistors connected to the protection
system during S1 duty and switched off during S2 duty (operation
during an emergency).
These qualifications ensure the qualification of the driven fan by the
manufacturer.
Maintenance Constraints
Regular service visits must be performed on the installation AT
LEAST EVERY 6 MONTHS, incorporating the following checks:
i. Checking the insulation resistance (R>100 MOhms, 500V DC)
•If the drain holes are blocked, open them to eliminate any
accumulated condensation.
•If R<100 MOhms, dry the stator in an oven and check the
insulation resistance. If the fault persists, replace the stator.
•The stator must be replaced 5 years after installation or after
20,000 hours of operation.
ii. Cooling check
•Ensure there is no dust or grease in the entire ventilation circuit
(housing fins, motor cover/fan if fitted driven fan).
•Ensure the motor runs normally when switched on for a few
minutes.
iii. Bearing check (C3 or C4 play)
Run the motor during each maintenance visit. When the motor is cold,
a high level of noise may be caused by the texture of the grease. This
does not indicate a bearing fault.
S2 duty only:
The bearings must be replaced by an identical type every 5 years.
Ensure the motor runs normally when switched on for a few minutes.
S1 duty and Emergency in S2 duty:
a) Permanently greased bearings.
400°C range; replace on 2 pole motors after 10,000 hours of operation
and on motors with 4 poles or more after 20,000 hours.
b) Re-greaseable bearings
The information on the motor nameplates must be strictly respected
(grease quantity, grease quality and re-greasing frequency).
The bearings must be replaced after 20,000 hours of operation.

4.3 Flanges and connection spigots are provided for the purpose of joining to duct work systems.They must not
be used to support the ductwork.
4.4 Local Environment - Humidity. Ambient humidity (the humidity at the unit’s installed location) shall be
within the range: 10 to 95% (for controls, non-condensing).
Air humidity (the humidity of the air passing through the unit) shall be within the range: 10 to 95% (for
controls, non-condensing).
5.0 INSTALLATION REQUIREMENTS
In addition to the particular requirements given for the individual product, the following general requirements
should be noted.
5.1 Where access to any part of equipment which moves, or can become electrically live are not prevented by
the equipment panels or by fixed installation detail (e.g. ducting), then guarding to the appropriate standard
must be fitted.
5.2 The electrical installation of the equipment must comply with the requirements of the relevant local
electrical safety regulations.
5.3 For good EMC engineering practice all control and sensor cables should not be placed within
50mm of 230V cables.
5.4 For fans with electronic speed control, protection against surges L/N-E is recommended on the supply.
5.5 Fans with electronic speed/inverter control should be connected to an Industrial not Public Low Voltage
supply.
6.0 COMMISSIONING REQUIREMENTS
6.1 General pre-commissioning checks relevant to safe operation consist of the following:
Ensure that no foreign bodies are present within the fan or casing.
Check electrical safety e.g. Insulation and earthing.
Check guarding of system.
Check operation of Isolators/Controls.
Check fastenings for security.
6.2 Other commissioning requirements are given in the relevant product documentation.
7.0 OPERATIONAL REQUIREMENTS
7.1 Equipment access panels must be in place at all times during operation of the unit, and must be secured with
the original fastenings.
7.2 If failure of the equipment occurs or is suspected then it should be taken out of service until a competent
person can effect repair or examination (Note that certain ranges of equipment are designed
to detect and compensate for fan failure).
8.0 MAINTENANCE REQUIREMENTS
8.1 Specific maintenance requirements are given in the relevant product documentation.
8.2 It is important that the correct tools are used for the various tasks required.
8.3 If the access panels are to be removed for any reason the electrical supply to the unit must be isolated.
8.4 A minimum period of two minutes should be allowed after electrical disconnection before access panels are
removed. This will allow the impeller to come to rest.
NB: Care should still be taken however since airflow generated at some other point in the system can
cause the impeller to “windmill” even when power is not present.
8.5 Care should be taken when removing and storing access panels in windy conditions.
