6. REFRIGERANT PIPING WORK
r
For the outdoor unit refrigerant piping, refer to the installa-
tion manual attached to the outdoor unit.
r
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 250°F (120°C).
For use under high humidity, strengthen the insulation ma-
terial for refrigerant piping. If not strengthened, the surface
of insulation material may sweat.
r
Before installation work, make sure that the refrigerant is
R410A. (Unless the refrigerant is R410A, the nor mal opera-

If the refrigerant leaks during the work, ventilate the
room.

When connecting the pipings to the air conditioner,
make sure to use a spanner and a torque wrench as
