• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or a fire.
• Consult your dealer regarding what to do in case of refrigerant leakage.
When the air conditioner is installed in a small room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the concentration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen deficiency.
1 English
• 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 legislation (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.

6. REFRIGERANT PIPING WORK
• For the outdoor unit refrigerant piping, refer to the installation manual attached to the outdoor unit.
• Carry out insulation of both gas and liquid refrigerant piping securely. If not insulated, it may cause water
leakage. For gas piping, use insulation material of which heat resistant temperature is not less than 120°C.
For use under high humidity, strengthen the insulation material for refrigerant piping. If not strengthened,
the surface of insulation material may sweat.
• Before installation work, make sure that the refrigerant is R410A. (Unless the refrigerant is R410A, the normal operation cannot be expected.)
CAUTION
This air conditioner is a dedicated model for new refrigerant R410A. Make sure to meet the requirements
shown right and carry out installation work.
• Use dedicated piping cutters and flaring tools for R410A.
• When making a flare connection, coat the flared inner surface only with ether oil or ester oil.
• Use only the flare nuts attached to the air conditioner. If other flare nuts are used, it may cause refrigerant
leakage.
• To prevent contamination or moisture from getting into the piping, take measures such as pinching or tap-
ing the pipings.
Do not mix substance other than the specified refrigerant such as air into the refrigeration circuit.
If the refrigerant leaks during the work, ventilate the room.
• Remove the stay for packing and delivering (reinforcing plate) before refrigerant piping work.
(Refer to Fig. 18)
• The refrigerant is pre-charged in the outdoor unit.
• When connecting the pipings to the air conditioner, make sure to use a spanner and a torque wrench as
shown in Fig.13.
For the dimension of flared part, refer to the Table 1.
