2. Locate The Pipe
1) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then
set on the fittings such as the wall conduit and its cover.
2) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air
in, which will cause water leakage by condensation.
3) Pass the bound connecting pipe through the wall conduit from outside. Be careful of the
pipe allocation to do no damage to the tubing.
3. Connect the pipes.
4. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe conne-
cting the indoor unit with the outdoor unit fluently 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.

Too large torque will harm the bellmouthing and
too small will cause leakage.
