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

Safety Precaution
1

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.
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.
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.
Avoid the ceiling fan unit from exposing to direct sunlight, this may cause degradation of plastic
material as a result of excessive heat and UV radiation.
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 manufactur-
er, its service agent or suitably qualified persons.
Torque value for screw/bolts for securing primary suspension system for motor is 2Nm.

Due to the fan’s natural movement, connections may get loose after period of usage. To
ensure a proper and safety usage, it is highly recommended to inspect and tighten all
connections every 6 months.
Cleaning
Cleaning your fan periodically will prolong its new appearance. Basic cleaning procedures
are as follows :
1. Use only water and mild soap. Do not use solvents, corrosive or acidic solution.
2. Damp the cloth lightly. Use only soft or lint-free cloth to clean the fan. Rough fabric will
