Ⅰ.USES
THE VENTILATION FAN is installed in a wall opening for exchanging air from
one side of the wall to the other. It can expel indoor foul air take in fresh air to
provide a well ventilated environment, regulate in-house temperature, remove
dampness, as well as to prevent the accumulation of poisonous gas. With its
reliable insulating properties, a sufficient air volume, and an attractive outlook, it
is highly recommended for indoor air conditioning and discharging smoke and
dust in industrial and other public premises.

Ⅴ.OPERATION

1. Before installing, check if the voltage and frequency on the data plate are
applicable to local power supply, turn the blade with hand to see if the motor
shaft runs smoothly.
2. The FAN should be installed at a place over 2.3 metres above the ground and
fixed on the wall or a special frame with nuts. The motor shaft should be on a
parallel with the ground.
3. When switched on, the FAN should get started and run smoothly. But if
power is on, and the FAN refuses to run, check if the fuse is cut out, or the
cords are properly and firmly connected. If the above are not the causes for
failure, send for a professional to check.
4. The yellow-green cord is an earth wire, which must be properly connected by
a professional.
Ⅵ.MAINTENANCE AND PRESERVATION
1. When installing or removing, do not bump the blades or willfully alter their
angles.
2. Put several drops of sewing machine oil into the oil ways on the front and rear
shells at regular intervals (Once after 3 months of 24-hour use or 6 months of
regular use). It is recommended to check up the FAN once a year to achieve
the best performance.
3. Before removing the FAN body, cut off the power first. The blades can be
taken down and cleaned with cotton or soft cloth wet with soap water. (Do not
use petrol or any other corrosive liquids harmful to paints).
4. Use or keep FAN in well-ventilated places without corrosive gases.
