WARNING
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.)
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 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 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.

01_EN_3P249378-8N.fm Page 10 Saturday, September 29, 2012 3:02 PM
• 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.

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.
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.
