Refer these for further motor guidance. Electrical connections are made

in accordance with connection diagram in the motor instructions and/or

inside motor terminal box.

Many S&P fans are supplied with a cable gland for typical electrical power

cable connection, to assist installation. However, if Installer uses a cable

requiring a differing cable gland, this is to be supplied by the Installer, no

alternative is offered by S&P. The Installer is responsible to ensure that

cable, and cable gland, are suitable and safe for application according to

country regulations.

Ensure system operation is safe in event of power cut/power outage/dis-

ruption to power supply. If ventilation is stopped due to disruption to pow-

er supply, ensure no risk due to excessive temperature (electrical heater).

Care may be needed when restarting fan after disruption to power supply.

Most motors are supplied with permanently greased or sealed for life

bearings and do not require re-lubrication. However, if motors with

re-greasing facility are supplied, then follow the instructions in the spe-

c motor Instruction manual and nameplate supplied.

Warning: Do not mix different types of grease.

Motors with speed control via Variable Speed Drive (VSD) Frequency In-
verter, should not be run in excess of nameplate speed. In general appli-
cations, we recommend not to run at less than 20% of nameplate speed
without reference to manufacturer, since this may damage the motor.
However, the fan shall not operate below 40% of its nominal rpm (20Hz).
If you are using cable longer than 20 meters between the drive and the
motor, add output sinusoidal ﬁ lter.
If you are using cable longer than 50 meters between the drive and the
motor, add output EMC ﬁ lter.

MAINTENANCE, REPAIRS

Maintenance/repairs must be carried out by competent personnel and
in accordance with applicable International, National and Local regu-
lations. Fan equipment should be electrically isolated and locked out
before any work started.

Fan equipment should be regularly cleaned, frequency depending upon

service load and application, but no less than every 6 months. Fan equip-

ment for dust applications may require more frequent cleaning to ensure

safe operation. Cleaning should include all areas where dust can accu-

mulate in the fan equipment.

Special attention should be made to any unusual sounds, vibration or

temperature. If any problems are detected the fan equipment should

be stopped immediately and cause inspected. The impeller and blades

should be regularly checked for damage that could cause imbalance in

the moving parts.

REPLACEMENT PARTS

Do not start working until all relevant safety procedures have been
read, understood and actioned correctly.

Ensure that personnel are competent for work required, spare parts are

correct for application, tools and materials to be used are available and

safe for environment.

Identify components, bolts,

xings to be removed, and identify location

to ensure replaced in same location, this can be done by marking with

number/letter/colour to bolt

xing and any associated spacing materi-

al to identify location. This is especially important for motor

xings to

supports, and impeller shaft

xings to supports, where packing/spacing/

shim material is used to adjust motor/impeller shaft center line, and

hence

nal impeller position.

REPLACEMENT BELTS (see drawings)

Fan equipment should be electrically isolated and locked out before any
work started.

The tension of belt drives should be regularly checked to avoid slippage,

miss-alignment or excessive force being placed on moving parts.

Ensure new belts comply with fan name plate data. If new belts are re-

ted ensure all belts be replaced, with a new matched set from the same

supplier. Never reuse belts.

Reduce belt tension by adjusting motor slide rails / screw adjustment,

remove all belts, re

t all new belts, adjust motor slide rails screw adjust-

ment to ensure belt tension is correct.

Pulleys must be correctly aligned, strictly observing the perpendicularity

of their respective axles.

Check gap between rotating parts and

xed parts is minimum of 2mm.

GOOD PRACTICE, GOOD/BAD INSTALLATION ARRANGEMENT

Fans are designed and performance tested in accordance with standard
duct arrangements. Thus they should be installed correctly without any
adverse installation effect. Typically fans should be installed so that air
entry is clear, unobstructed, non-turbulent and discharge does not hin-
der airﬂ ow, since air turbulence adversely affects impeller performance.

PUTTING OUT OF SERVICE AND RECYCLING

Disposal must be carried out by competent personnel and in accordance

with applicable International, National and Local regulations.

Isolate fan equipment and any associated electrical equipment and lock

off. Remove electrical connections.

Disconnect fan equipment from duct connections and cover connections

with plastic sheet to prevent exposure to any residue material in fan

equipment, and any contamination of ducts.

Dismantle and dispose in accordance with applicable National and Inter-

national laws and regulations, those parts whose service life has expired.

EEC legislation and our consideration of future generations

mean that we should always recycle materials where possible;
