Installation instruction
When bending the pipes, give the roundness as
large as possible, to avoid crashing and flat the
pipes.
To connect the pipe, fit the center and use hand
to screw the nut, as shown in figure:
If do not fit the center and screw the nut hard,
the screw thread may be damaged, which will
cause refrigerant leakage.
Pay attention not to let alien matters, such as
sand, water get into the pipe.
(3)Connect the connection pipe of outdoor unit
According to the connection method to connect the connection pipe and in/out
liquid pipe and gas pipe.
2. Welding method of pipe
(1)The refrigerant pipe should use clean new pipe. When performing work,
pay attention to preventing vapor, dust from entering into the pipe.
(2)When loosening and fastening the connection screw nut, do use two hands
to handle. If use one hand, it cannot reach the necessary fastening level.
Please perform the fastening of the screw nut according to the specified torque

*15.88
3. Cut and flaring method
Use pipe cutter to cut the pipe, the burrs must be removed.
After inserting the flarer, perform flared nut.

When connect the accessory thermal insulation material with the thermal insulation
material of the onsite connection pipe, do not leave any gap. After finishing installing the
thermal insulation material as below Figure shown, then use tape to bind them properly.
When connection, the connecting part
should not leave any gap, and the thermal
insulation material should be overlapped.
