d. Wrap the exposed refrigerant pipe and the joints by sponge and then tighten them with the plastic tape.

① .
During the connection of the indoor unit and the refrigerant pipe, never pull any joints of the indoor
unit by force; otherwise the capillary pipe or other pipe may crack, which then would result in leakage.
② .
The refrigerant pipe should be supported by brackets, that is, don’t let the unit withstand the weight of
it.
14 Insulation for the Refrigerant Pipe
a. The refrigerant pipe should be insulated by the insulating material and plastic tape in order to prevent
condensing and leaking.
b. The joints of the indoor unit should be wrapped with the insulating material and no gas is allowed on
the joint of the indoor unit, as shown in Fig.19.
No gap

After the pipe is protected well enough, never bend it to form a small angle; otherwise it would crack or
break.
c. Wrapping the pipe with tape.
1) Bundle the refrigerant pipe and electric wire together with tape, and separate them from the drain pipe
to prevent the condensate water overflowing.
2) 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.
3) Fix the wrapped pipe on the wall with clamps.

① .
Do not wrap the pipe too tightly; otherwise the insulation effect would be weakened. Additionally,
make sure the drain hose is separated from the pipe
② .
After that, fill the hole on the wall with sealing material to prevent wind and rain coming into the
room.
15 Wiring between the Wire and the Wiring Terminal
a. Wiring of the Single-Core Wire
1) Strip the insulating layer at the end of the wire about 25mm off with a wire striper.
2) Loosen the screw off on the wiring board of the air conditioning unit.
3) Shape with the pliers the end of the wire to a circle matching with the size of the screw.
4) Let the screw go through the circle of the wire and then fix it on the wiring board.
b. Wiring of the Multi-Core Wire
1) Strip the insulating layer at the end of the wire about 100mm off with a wire striper.
2 Loosen the screw off on the wiring board of the air conditioning unit.
3) Fix a wiring terminal matching with the size of the screw to the end of the multi-core wire with the
