8.11 Installation of Protective Layer of Connecting Pipe
To avoid generation of condensate on the connecting pipe and leakage, the big pipe and the small pipe of
1.
the connecting pipe must be covered by thermal insulation materials, be bundled by adhesive tape, and
be isolated from air.
The joint connecting to the indoor unit must be wrapped by thermal insulation material. There shall be no
2.
gap between the connecting pipe joint and the wall of the indoor unit. Refer to Fig. 8.14.

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.
Use adhesive tape to wrap the pipes:
3.
Use adhesive tape to bundle the connecting pipe and the cables together. To prevent condensate from
(1)
overfl owing out from the drainage pipe, separate the drainage pipe from the connecting pipe and the cables.
Use thermal insulation tape to wrap the pipes from the bottom of the outdoor unit until the upper end of
(2)
the pipe where the pipe enters the wall. When wrapping thermal insulation tape, the later circle of tape
must cover half of the front circle of tape (Refer to Fig. 8.15).
Wrapped pipe must be fi xed to wall using pipe clamps.
(3)
CAUTION
Do not wrap the protective tape too tight, otherwise the effi ciency of thermal insulation may be decreased.
(1)
Ensure that the condensate drainage fl exible tube is separated from the bundled pipes.
After the protective work is completed and the pipes are wrapped, use seal material to block the hole in
(2)
the wall, so as to prevent rain and wind from entering the room.
8.12 Position and Method of Installing Wired Controller
One end of the controlling wire of the wired controller is connected with electricbox mainboard of indoor
1.
unit inside, it should be tightened by wire clamp, the other end should be connected with the wired control-
ler (installation sketch map as shown in below). The special control wire used for the indoor unit and wired
controller is 8 meters.
The material adopted for the control wire should be metallic. The wired controller could not be disassem-
2.
bled and the control wire used for the wired controller should not be changed by user’s option, the installa-
tion and should be carried out by the professional personnel.
First select an installation position. Leave a recess or an embedded wire hole to bury the control wire
3.
according to the size of the control wire of the wired controller.
If the control wire between the wired controller and the indoor unit is surface-mounted, use 1# metallic
4.
pipe and make matching recess in the wall (refer to Fig. 8.16). If concealed installation is adopted, mount
as Fig.8.17.
No matter surface mounting or concealed mounting is selected, it is required to drill 2 holes (in the same
5.
level) distance of which shall be the same as the distance (60mm) of installation holes in the bottom plate
of the wired controller. Then insert a wood plug into the holes. Fix the bottom plate of the wired controller
to the wall according the two holes. Plug the control wire onto the wired controller. Then, install the panel
of the wired controller (Refer to Fig.8.18).
