1. 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 con-
ditioner 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”.
Safety Precaution
This unit is a class A product. In a domestic environment this
product may cause radio interference in which case the user
may be required to take adequate measures.
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 dam-
age or personal injury, which may be
serious depending on the circum-
stances.
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 refrig-
erant 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 equip-
ment 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 electric parts box lid can be securely fastened.
Improper positioning of the electric parts 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 con-
tact 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.
• 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 elec-
tric 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 elec-
tric 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 connect-
ing 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.
