Use the market brass pipe
Be sure to use the same insulating materials when you buy the brass pipe (more than 9mm thick).
2. Locate The Pipes
Drill a hole in the wall (suitable just for the size of the wall conduit, 53, 71 series diameter is
and 120,105,140 series diameter is
conduit and its cover.
Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which
will cause water leakage by condensation.
Pass the bound connecting pipe through the wall conduit from outside. Be careful of the pipe alloc-
ation to do no damage to the tubing.
3. Connect the pipes.
4. Then, open the stem of stop values of the outdoor unit to make the refrigerant pipe connec-
ting the indoor unit with the outdoor unit in fluent flow.
5. Be sure of no leakage by checking it with leak detector or soap water.
6. Cover the joint of the connecting pipe to the indoor unit with the soundproof / insulating
sheath (fittings), and bind it well with the tapes to prevent leakage.

Fasten the nuts
Put the connecting tubing at the proper position,
wrench the nuts with hands, then fasten it with a
wrench.( Refer to Chart24)

CAUTIONS
Too large torque will harm the bellmouthing
and too small will cause leakage. Please
determine the torque according to Table 2.
