Bind the connecting pipe and the cables together tightly with
binding tapes. Pass the bound connecting pipe through the
wall conduct from outside. Be careful of the pipe allocation to
do on damage to the tubing.
Connect the pipes. Refer to“How to Connect the pipes”for details.
Expel the air with a vacuum pump. Refer to“How to expel the air
with a vacuum pump” for details.
Open the stop values of the outdoor unit to make the refrigerant
pipe connecting the indoor unit with the outdoor unit in uent
ow.
Check the leakage. Check all the joints with the leak detector
or soap water.
Cover the joints of the connecting pipe with the soundproof /
insulating sheath (ttings), and bind it well with the tapes to
prevent leakage.
Be sure to with insulating materials cover all the exposed parts of
the are pipe joints and refrigerant pipe on the liquid-side and the
gas-side. Ensure that there is no gap between them.
Incomplete insulation may cause water condensation.
How to Connect the pipes

Connect the indoor unit at rst, then the outdoor unit.
Bend the tubing in proper way. Do not harm to them.
The bending angle should not exceed 90º.
Bending position is preferably in the middle of the bendable
pipe. The larger the bending radius the better it is .
Do not bend the pipe more than three times.
When connecting the are nut, coat the are both inside and
outside with either oil or ester oil and initially tighten by hand 3
or 4 turns before lighting rmly.
Be sure to use both a spanner and torque wrench together
when connecting or disconnecting pipes to /from the unit.
Too large torque will harm the bellmouthing and too small will cause
leakage. Please determine the torque according to Table 7-2.
After the connecting work is nished, be sure to check that there is no
gas leak.
