• When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the
wires so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric shocks, fire or the terminals overheating.

• If the refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant gas comes into contact with fire.

• After completing the installation work, check that the refrigerant gas does not leak.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source
of fire, such as a fan heater, stove or cooker.

• Before touching electrical parts, turn off the unit.

CAUTION

• Ground the air conditioner.

Do not connect the ground wire to gas or water pipes, lightning conductor or a telephone ground wire.
Incomplete grounding may result in electric shocks.

• Be sure to install an earth leakage breaker.

drainage and insulate piping in order to prevent condensate.
Improper drain piping may result in water leakage and property damage.

• Install the indoor and outdoor units, power supply wiring and connecting wiring at least 1 meter away from
televisions or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the noise.)

• Remote controller (wireless kit) transmitting distance can result shorter than expected in rooms with elec­tronic fluorescent lamps (inverter or rapid start types).
Install the indoor unit as far away from fluorescent lamps as possible.

• Do not install the air conditioner in the following locations:
(a)where a mineral oil mist or an oil spray or vapor is produced, for example in a kitchen

Plastic parts may deteriorate and fall off or result in water leakage.

(b)where corrosive gas, such as sulfurous acid gas, is produced

Corroding copper pipes or soldered parts may result in refrigerant leakage.

(c) near machinery emitting electromagnetic waves

Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the
equipment.

(d)where flammable gases may leak, where there are carbon fiber or ignitable dust suspensions in the air,

or where volatile flammables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.

2. BEFORE INSTALLATION

• Do not exert pressure on the resin parts when opening the unit or when moving it after opening.

• Be sure to check the type of refrigerant to be used before installing the unit. (Using an incorrect refrigerant
