9 Installation of Protective Layer on Connection Pipe
1) The refrigerant pipes should be insulated by the heat insulation material and plastic tape in order to
prevent water condensation and leakage.
2) Do not use the foam on the branch pipe as the material for heat insulation.
The heat insulation material: Heat resistance to 100 or more; ℃ Thickness of 9mm or more.
3) The joints of the system should be wrapped with the heat insulation material and no gap is allowed on the
joint of the system, as shown in the following figure.
4) Bundle the refrigerant pipe and transmission line together with tape, and separate them from the drain pipe
to prevent the condensate water overflowing.
5) Wrap the pipe from the bottom of the outdoor unit to the top of the pipe where it enters the wall. During
the wrapping, the later circle should cover half of the former one.
6) At intervals of about 1 meter, fix the refrigerant pipes to the wall with brackets, that is, don’t let the unit
withstand the weight of it or float it in the air.
Caution！
After the pipe is protected well enough, never bend it to form a small angle(＜90°), otherwise it would
crack or break.
Do not wrap the refrigerant pipes very tight, otherwise the insulation effect would be weakened.
Additionally, make sure the drain hose is separated from the refrigerant pipes.
After that, cover the hole on the wall with sealing materials to prevent wind and noise going into the
room.
