Be sure to use only the specified parts and accessories for installation work.
Failure to use the specified parts may result in the air conditioner falling down, water leakage, electric 
shocks, a fire, etc.

Install the air conditioner on a foundation that can withstand its mass.
Insufficient strength may result in the air conditioner falling down and causing injury.
In addition, it may lead to vibration of indoor units and cause unpleasant chattering noise.

Carry out the specified installation work in consideration of strong winds, typhoons, or earthquakes.
Improper installation may result in an accident such as air conditioner falling.

Make certain that all electrical work is carried out by qualified personnel according to the applicable legis-
lation (note 1) and this installation manual, using a separate circuit. 
In addition, even if the wiring is short, make sure to use a wiring that has sufficient length and never connect 
additional wiring to make the length sufficient.
Insufficient capacity of the power supply circuit or improper electrical construction may lead to electric 
shocks or a fire. 
(note 1) applicable legislation means “All international, national and local directives, laws, regulations and/

or codes which are relevant and applicable for a certain product or domain”.

Earth the air conditioner.
Do not connect the earth wiring to gas or water piping, lightning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.

Be sure to install an earth leakage breaker.
Failure to do so may cause electric shocks and a fire.

Disconnect the power supply before touching the electric components.
If you touch the live part, you may get an electric shocks.

Make sure that all wiring is secure, using the specified wirings and ensuring that external forces do not act 
on the terminal connections or wirings.
Incomplete connection or fixing may cause an overheat or a fire.

When wiring between the indoor and outdoor units, and wiring the power supply, form the wirings orderly 
so that the control box lid can be securely fastened.
If the control box lid is not in place, overheat of the terminals, electric shocks or a fire may be caused.

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

After completing the installation work, check to make sure that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room and comes into contact with a source of 
a fire, such as a fan heater, stove or cooker.

Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.

CAUTION

Install drain piping according to this installation manual to ensure good drainage, and insulate the piping to 
prevent condensation. 
Improper drain piping may cause water leakage, make the furniture get wet.

Install the air conditioner, power supply wiring, remote controller wiring and transmission wiring at least 
1 meter away from televisions or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be sufficient to eliminate the noise.)

Install the indoor unit as far as possible from fluorescent lamps.
If a wireless remote controller kit is installed, the transmission distance may be shorter in a room where an 
electronic lighting type (inverter or rapid start type) fluorescent lamp is installed.

Do not install the air conditioner in places such as the following:
1. Where there is mist of oil, oil spray or vapour for example a kitchen.

Resin parts may deteriorate, and cause them to fall out or water to leak. 

2. Where corrosive gas, such as sulfurous acid gas, is produced.

Corrosion of copper pipings or brazed parts may cause the refrigerant to leak.

3. Where there is machinery which emits electromagnetic waves.

Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.

4. Where flammable gases may leak, where carbon fibre or ignitable dust is suspended in the air or where 

volatile flammables, such as thinner or gasoline, are handled.
If the gas should leak and remained around the air conditioner, it may cause ignition.

The air conditioner is not intended for use in a potentionally explosive atomosphere.
