outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in during
installation.
The temperature of refrigerant circuit will be high, please keep
the interconnection cable away from the copper tube.

5.1 The Procedure of Connecting Pipes
5.1.1 Measure the necessary length of the connecting pipe, and
make it by the following way.
1) Connect the indoor unit at first, then the outdoor unit.
a. Bend the tubing in proper way. Don,t harm them.
1. Daub the surfaces of the flare pipe and the joint nuts with
frozen oil, and wrench it for 3~4 rounds with hands before
fasten the flare nuts.
2. Be sure to use two wrenches simultaneously when you
connect or disconnect the pipes.
CAUTION
2) The stop valve of the outdoor unit should be closed
absolutely (as original state). Every time you connect it, first
loosen the nuts at the part of stop valve, then connect the flare
pipe immediately (in 5 minutes). If the nuts have been loosened
for a long time, dusts and other impurities may enter the pipe
system and may cause malfunction later. So please expel the
air out of the pipe with refrigerant before connection.
3) Expel the air (refer to the “Expel The Air”) after connecting
the refrigerant pipe with the indoor unit and the outdoor unit.
Then fasten the nuts at the repair-points.
Notices For Benable pipe.
The bending angle should not exceed 90°.
Bending position is preferably in the bendable pipe. The
larger the better it is .
Do not bend the pipe more than three times.
