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/disruption to power supply. If
ventilation is stopped due to disruption to pow-
er supply, ensure no risk due to excessive tem-
perature (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 specifi 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 Inverter, should not be
run in excess of nameplate speed. In general ap-
plications, 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 be-
tween the drive and the motor, add output sinu-
soidal fi lter.
If you are using cable longer than 50 meters be-
tween 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
regulations. Fan equipment should be electri-
cally isolated and locked out before any work
started.
Fan equipment should be regularly cleaned,
frequency depending upon service load and ap-
plication, but no less than every 6 months. Fan
equipment for dust applications may require
more frequent cleaning to ensure safe operation.
Cleaning should include all areas where dust can
accumulate in the fan equipment.
Special attention should be made to any unusual
sounds, vibration or temperature. If any prob-
lems 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 ac-
tioned 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, fi xings to be removed,
and identify location to ensure replaced in same
location, this can be done by marking with num-
ber/letter/colour to bolt fi xing and any associated
spacing material to identify location. This is es-
pecially important for motor fi xings to supports,
and impeller shaft fi xings to supports, where
packing/spacing/shim material is used to adjust
motor/impeller shaft center line, and hence fi nal
impeller position.
GOOD PRACTICE, GOOD/BAD INSTALLA-
TION ARRANGEMENT
Fans are designed and performance tested in ac-
cordance 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, unobstruct-
ed, non-turbulent and discharge does not hinder
airfl ow, since air turbulence adversely affects
impeller performance.
PUTTING OUT OF SERVICE
AND RECYCLING
Disposal must be carried out by competent per-
sonnel and in accordance with applicable Inter-
national, National and Local regulations.
Isolate fan equipment and any associated elec-
trical equipment and lock off. Remove electrical
connections.
Disconnect fan equipment from duct connec-
tions 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 appli-
cable National and International laws and regula-
tions, those parts whose service life has expired.
