1) Outdoor unit
Warning:
• The outdoor unit must be installed on a stable, level surface, in a place
where there is no accumulation of snow, leaves or rubbish.
• Do not stand on, or place any items on the unit. You may fall down or the
item may fall, causing injury.
Caution:
The outdoor unit should be installed in a location where air and noise emitted
by the unit will not disturb the neighbours.
2) Indoor unit
Warning:
The indoor unit should be securely installed. If the unit is loosely mounted, it
may fall, causing injury.
3) Remote controller
Warning:
The remote controller should be installed in such a way that children cannot
play with it.
4) Drain hose
Caution:
Make sure that the drain hose is installed so that drainage can go ahead
smoothly. Incorrect installation may result in water leakage, causing damage
to furniture.
5) Power line, fuse or circuit breaker
Warning:
• Make sure that the unit is powered by a dedicated supply. Other appliances
connected to the same supply could cause an overload.
• Make sure that there is a main power switch.
• Be sure to adhere to the unit's voltage and fuse or circuit breaker ratings.
Never use a piece of wire or a fuse with a higher rating than the one speci-
fied.
6) Grounding
Caution:
• The unit must be properly grounded. Never connect the grounding wire to a
water pipe, lightning conductor or telephone grounding wire. If the unit is
not grounded properly, electric shock may result.
• Check frequently that the ground wire from the outdoor unit is properly con-
nected to both the unit's ground terminal and the grounding electrode.

1.2. During operation

Caution:
• Do not use any sharp object to push the buttons, as this may damage the
remote controller.
• Do not twist or tug on the remote controller cord as this may damage the
remote controller and cause malfunction.
• Never remove the upper case of the remote controller. It is dangerous to
remove the upper case of the remote controller and touch the printed circuit
boards inside. Doing so can result in fire and failure.
• Never wipe the remote controller with benzene, thinner, chemical rags, etc.
Doing so can result in discoloration and failure. To remove heavy stains,
soak a cloth in neutral detergent mixed with water, wring it out thoroughly,
wipe the stains off, and wipe again with a dry cloth.
• Never block or cover the indoor or outdoor unit's intakes or outlets. Tall
items of furniture underneath the indoor unit, or bulky items such as large
boxes placed close to the outdoor unit will reduce the unit's efficiency.
Warning:
• Do not splash water over the unit and do not touch the unit with wet hands.
An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
