SAFETY PRECAUTIONS
Please read these “SAFETY PRECAUTIONS” carefully before installing air conditioning unit 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.
WARNING
• 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.
• Consult your local dealer regarding what to do in case of refrigerant leakage. When the air conditioner is to be installed in a
small room, it is necessary to take proper measures so that the amount of any leaked refrigerant does not exceed the concen-
tration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen depletion.
• 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 per-
sonnel 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 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 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 touch the switch with wet hands.
Touching the switch with wet hands can cause electric shock.
• 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.
• Make sure to charge the specified refrigerant into the refrigerant piping. Do not mix with air or other gases; otherwise it may
cause abnormally high pressure or explosion.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
