Instructions of Unit Installation Installation of Connecting Pipe
Installation of Protective Layer of Connecting Pipe
1.
To avoid generation of condensate on the connecting pipe and avoid leakage, the big pipe and the
small pipe of the connecting pipe must be covered by thermal insulation materials, be bundled by
adhesive tape, and be isolated from air.
2.
The joint connecting to the indoor unit must be wrapped by thermal insulation material. There shall
be no gap between the connecting pipe joint and the wall of the indoor unit. Refer to Figure
1

No Gap
Caution:
After the pipes are wrapped by protective materials, never bend the pipes to form very
small angle, and otherwise the pipes may crack or break.
3.
Use adhesive tape to wrap the pipes:
(1)
Use adhesive tape to bundle the connecting pipe and the cables together. To prevent
condensate from overflowing out from the drainage pipe, separate the drainage pipe firm the
connecting pipe and the cables.

Wrapped pipe must be fixed to wall using pipe clamps.
Caution:
（1）
Do not wrap the protective tape too tight, and otherwise the efficiency of thermal insulation
may be decreased. Ensure that the condensate drainage flexible tube is separate from the
bundled pipes.
（2）
After the protective work is completed and the pipes are wrapped, use seal material to block
the hole in the wall, so as to prevent rain and wind from entering the room.
Position and Method of Installing Wire Controller
1. One end of the control wire of the manual controller is connected with main board of electric box of
indoor unit inside, it should be tightened by wire clamp, the other end should be connected with the
manual controller (installation sketch map as shown in below). The control wire be used for the
indoor unit and manual controller, which is the special communication wire, the length is 8 meters,
the material be adopted for the control wire should be metallic substance. The manual controller
could not be disassembled and the communication wire be used for the manual controller should not
be changed by users optionally, the installation and maintenance should be carried out by the
professional personnel.
2. First select an installation position. According to the size of the communication line of the wire
controller, leave a recess or a embedded wire hole to bury the communication line.
3.
If the communication line between the wire controller and the indoor unit is
surface-mounted, use 1# metallic pipe and make matching recess in the wall (refer to Figure
1
1);
