1. SAFETY PRECAUTIONS

Please read these “SAFETY PRECAUTIONS” carefully before installing air conditioning equipment and be sure to install it correctly. After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual. Ask the customer to store the installation manual along with the operation manual for future reference. This air conditioner comes under the term “appliances not accessible to the general public”.

Meaning of WARNING and CAUTION notices.

WARNING .........Failure to follow these instructions properly may result in personal injury or loss of life.

CAUTION ..........Failure to observe these instructions properly may result in property damage or per-

sonal injury, which may be serious depending on the circumstances.

• Ask your dealer or qualified personnel to carry out installation work. Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire.

• Install the air conditioner in accordance with the instructions in this installation manual. Improper installation may result in water leakage, electric shocks or fire.

• 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.

English 1

• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried

CAUTION

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 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 overheating terminals.

• 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.

• 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.

• The air conditioner is not intended for use in a potentially explosive atmosphere.

2 English

2. BEFORE INSTALLATION

Do not dispose of any parts necessary for installation until the installation is completed.

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 R410A refrigerant to be used before doing any work. (Using an incorrect refrigerant will prevent normal operation of the unit.)

• When opening the unit or moving it after opening, be sure to lift it by holding on to the lifting lugs without

exerting any pressure on other parts, especially, drain piping, and other resin parts.

• Decide upon a line of transport.

• Leave the unit inside its packaging while moving, until reaching the installation site. Use a sling of soft mate-

rial, where unpacking is unavoidable or protective plates together with a rope when lifting, to avoid damage or scratches to the unit.

• Refer to the installation manual of the outdoor unit for items not described in this manual.

• Do not dispose of any parts necessary for installation until the installation is complete.

• In order to protect the indoor unit from damage, use packing materials to protect the unit after carrying until

the installation starts.

• When selecting installation site, refer to the paper pattern.

• Do not use the unit in locations with high salt content in the air such as beachfront property, locations where

the voltage fluctuates such as factories, or in automobiles or marine vessels.
