Safety
Precaution
WARNING
Installation and maintenance work shall only be performed by qualified persons, familiar with local
code and regulation, and experienced with this type of appliance.
All field wiring must be installed in accordance with the national wiring regulation.
Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing
wiring work according to the wiring diagram.
The appliance must be permanently connected to the electricity supply through a double
pole switch having a contact separation of at least 3mm in all poles.
The unit must be GROUNDED to prevent possible hazard due to insulation failure.
The earth wire is approximately 60mm longer than safety wire. This is to ensure at the event whereby
the suspension system fails, the (L) and (N) wire will break leaving the fan remain earthed to prevent
electrocution.
Tighten the blade firmly using a screw driver.
Blades that are detached from the unit during operation will cause serious injuries and property
damages. 1

Safety
Precaution
WARNING
This appliance is not intended for use by persons (including children) with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
Confirm that the power supply has been switched OFF before installing or servicing the unit. Ensure
that the blade is fully static before doing any maintenance work.
Disconnect from the main power supply before servicing the unit.
DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks
which may result in fire hazards.
STOP using the ceiling fan when any abnormality or failure occurs.
If unusual oscillating movement is observed, immediately stop using the ceiling fan and contact the
manufacturer, its service agent or suitably qualified persons.

Safety
Precaution
CAUTION
Please take note of the following important points when installing.
The fixing means for attachment to the ceiling such as hooks or other devices shall be fixed with a
sufficient strength to withstand 4 times the weight of the ceiling fan.
The mounting of the suspension system shall be performed by the manufacturer, its service agent
or suitably qualified persons.
The fan is to be installed so that the blades are more than 2.5m above the floor.
Safety cord should not be longer than the earthing conductor.
Should failure of the suspension system occur, the supporting of the fan must not rely on the
earthing conductor. The earthing terminal in the fan assembly should be such that should any part
of the suspension system fall off, the body of the fan assembly shall effectively earthed.
Ensure that the unit’s panel is closed after service or installation.
Unsecured panels will cause the unit to operate noisily.
Sharp edges and coil surfaces are potential locations which may cause injury hazards.
Avoid from being in contact with these places. 3

CAUTION
Before turning off the power supply set the remote controller’s ON/OFF switch to the “OFF”
position.
If this is not done, the unit’s fans will start turning automatically when power resumes, posing a hazard to
service personnel or the user.
Do not operate any heating apparatus too close to the ceiling fan unit or use in room where mineral oil,
oil vapour or oil steam exist, this may cause plastic part to melt or deform as a result of excessive heat
or chemical reaction.
Ensure the colour of wires of the outdoor unit and the terminal markings are same to the indoors
respectively.
Do not use joined and twisted wires for incoming power supply.
Do not place any object in the path of the blades. Avoid raising objects or your arms near the ceiling fan.
The fan suspension system and blade screw tightening shall be examined yearly.
Replacement of parts of the safety suspension system device shall be performed by the manufacturer,
its service agent or suitably qualified persons.
Torque value for screw/bolts for securing primary suspension system for motor is 2Nm.
