shocks or a fire.
• 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.
• 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.
1 English
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 potentially
explosive atmosphere.
2. BEFORE INSTALLATION
When unpacking and moving the indoor unit after
unpacked, do not apply force to the piping (refrigerant and
drain) and resin parts.
• Make sure to check in advance that the refrigerant to be used

English 6
The indoor unit must be securely installed on a place that
can withstand the mass.
If the strength is insufficient, the indoor unit may fall down and
cause injuries.
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.)
This air conditioner is a dedicated model for new refrigerant R410A. Make sure to meet the requirements shown
below 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
taping the pipings.
Do not mix substance other than the specified refriger-

ant 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.
• When making a flare connection, coat the flared inner surface only with ether oil or ester oil. (Refer to Fig. 14)
Then, turn the flare nut 3 to 4 times with your hand and screw
in the nut.
• If there is no torque wrench, use Table 2 as a rule of thumb.
When tightening a flare nut with a spanner harder and
harder, there is a point where the tightening torque suddenly
increases. From that position, tighten the nut additionally the
angle shown in Table 2. After the work is finished, check
securely that there is no gas leak. If the nut is not tightened
as instructed, it may cause slow refrigerant leak and result in
malfunction (such as does not cool or heat).

1. The proper pressure for having nitrogen flow through the
piping is approximately 0.02MPa, a pressure that makes
one feel like breeze and can be obtained through a pressure
reducing valve.
2. Do not use flux when brazing refrigerant piping. Use phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/BCu93P-710/795: ISO 3677) that does not require flux. (If
chlorinated flux is used, the piping will be corroded and, in
addition if fluorine is contained, the refrigerant oil will be
deteriorated and the refrigerant circuit will be affected
badly.)
3. When carrying out leakage test of refrigerant piping and the
indoor unit after the installation of indoor unit is finished,
confirm the connecting outdoor unit installation manual for
test pressure.
Refer to also the outdoor unit installation manual or technical document for refrigerant piping.
4. In case of refrigerant shortage due to forgetting additional
refrigerant charge etc., it will result in malfunction such as
does not cool or does not heat. Refer to the outdoor unit
installation manual or technical document for refrigerant
piping.
Do not use antioxidant when brazing piping.
It may result in malfunction of components and clogging of
piping due to residue.
