Installation Of Protective Layer On Connection Pipe - Gree GC201306 -1 Service Manual

9 Installation of Protective Layer on Connection Pipe

1) The refrigerant pipes should be insulated by the insulating 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.
3) The joints of the system should be wrapped with the insulating material and no gap is allowed on the joint
of the system.
4) Bundle the refrigerant pipe and
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.
