1. Safety precautions

2) Remote controller

Warning:

The remote controller should be installed in such a way that children cannot
play with it.

3) 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 dam-
age to furniture.

4) Power line, fuse or circuit breaker

Warning:

Make sure that the unit is powered by a dedicated line. Other appliances
connected to the same line 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
specified.

5) Grounding

Caution:

The unit must be properly grounded. Never connect the grounding wire
to a gas pipe, 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 unit is properly connected
to both the unit’s ground terminal and the grounding electrode.

1.2. During operation

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.

Do not place a gas heater or any other open-flame appliance where it will
be exposed to the air discharged from the unit. Incomplete combustion
may result.

Do not remove the front panel or the fan guard from the unit when it is
running. You could be injured if you touch rotating, hot or high-voltage
parts.

Never insert fingers, sticks etc. into the intakes or outlets, otherwise in-
jury may result, since the fan inside the unit rotates at high speed. Exer-
cise particular care when children are present.

If you detect odd smells, stop using the unit, turn off the power switch
and consult your dealer. Otherwise, a breakdown, electric shock or fire
may result.

When you notice exceptionally abnormal noise or vibration, stop opera-
tion, turn off the power switch, and contact your dealer.

Do not over-cool. The most suitable inside temperature is one that is
within 5

°

C of the outside temperature.

Do not leave handicapped people or infants sitting or standing in the
path of the airflow from the air-conditioner. This could cause health prob-
lems.

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.
