• When piping is complete, cut the removed penetration lid into
the shape of the piping using scissors and attach. As when
before removing the top penetration lid, secure the lead lines
for the swing motor and thermistor by passing them through
the cramp part on the top penetration lid.
(Refer to Fig. 12, 15)
• When doing this, block any gaps between the piping penetra-
tion lid and the pipes using putty to prevent dust from enter-
ing the indoor unit.
• 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. 16.
• For the dimension of flared part and the tightening torque,
refer to the Table 1.
• When making a flare connection, coat the flared inner sur-
face only with ether oil or ester oil.
(Refer to Fig. 17)
Then, turn the flare nut 3 to 4 times with your hand and screw
in the nut.
CAUTION
• Do not let oil get on the screw holders on the dressing board.
Oil can weaken the screw holders.
• Overtightening may damage the flare and cause a refrigerant
leakage.
