Be sure to use only the specified accessories and parts for installation work. 
Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.

Install the air conditioner on a foundation strong enough to withstand the weight of the unit. 
A foundation of insufficient strength may result in the equipment falling and causing injury.

Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes. 
Failure to do so during installation work may result in the unit falling and causing accidents.

Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried 
out by qualified personnel according to local laws and regulations and this installation manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.

Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal 
connections or wires.
Improper connections or securing of wires may result in abnormal heat build-up or fire.

When wiring the power supply and connecting the remote controller wiring and transmission wiring, position 
the wires so that the terminal box lid can be securely fastened.
Improper positioning of the terminal box lid may result in electric shocks, fire or the terminals overheating.

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

After completing installation, check for refrigerant gas leakage.
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.

Be sure to switch off the unit before touching any electrical parts.

Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there is a danger
of frostbite.

Be sure to earth the air conditioner. 
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead.
Imperfect earthing may result in electric shocks or fire.
A high surge current from lightning or other sources may cause damage to the air conditioner.

Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.

CAUTION

While following the instructions in this installation manual, install drain piping to ensure proper drainage and 
insulate piping to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.

Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions 
or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)

Remote controller (wireless kit) transmitting distance can be 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:
1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).

Plastic parts will deteriorate, parts may fall off and water leakage could result.

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

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

3. Near machinery emitting electromagnetic radiation.

Electromagnetic radiation may disturb the operation of the control system and result in a malfunction of 
the unit. 

4. Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in the air, or 

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