• Install the indoor unit leveled
If the unit is inclined and the drain piping side gets high, it may cause malfunction of a float switch and
results in water leakage.
However, for 2-way air discharge, install the unit inclined 1° downward to the drain piping.
• Attach nuts on the upper and lower side of hanger
If there is no upper nut and the lower nut is over-tightened, the hanging plate and the top plate will
deform and cause abnormal sound.
• Do not insert materials other than that specified into the clearance between the hanger and the washer
for hanger (3).
Unless the washers are properly attached, the hanging bolts may come off from the hanger.
WARNING
The indoor unit must be securely installed on a place that can withstand the mass.
If the strength is insufficient, the 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.)
CAUTION
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 either 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 piping.
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.

• The refrigerant is pre-charged in the outdoor unit.
• Use the flare nut attached to the air conditioner.
• When making a flare connection, coat the flared inner surface only with either oil or ester oil.
(Refer to Fig. 20)
Then, turn the flare nut 3 to 4 times with your hand and screw in the nut.
Coat the flare inner surface
only with ether oil or ester oil.
Fig. 20
CAUTION
Do not have oil adhere to the screw fixing part of resin parts.
If oil adheres, it may weaken the strength of screwed part.
• When connecting the piping to the air conditioner, make sure to use a spanner and a torque wrench as
shown in Fig. 21.
For the dimension of flared part and the tightening torque, refer to the Table 1.

CAUTION
Do not tighten flare nuts too tight.
If a flare nut cracks, the refrigerant may leak.
• 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).

NOTE
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/B-Cu93P-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.
CAUTION
Do not use antioxidant when brazing piping.
It may result in malfunction of components and clogging of piping due to residue.
