Instructions of Unit Installation
（2） Use thermal insulation tape to wrap the pipes from the bottom of the outdoor unit until the
upper end of 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 Figure 42).
（3） 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 wire 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
wire controller (installation sketch map as shown in below). The control wire be used for the
indoor unit and wire controller, which is special, the length is 8 meters,
the material be adopted for the control wire should be metallic substance. The wire controller
could not be disassembled and the control wire be used for the wire 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 control wire of the wire
controller, leave a recess or a embedded wire hole to bury the control wire.
3. If the control wire 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 43; If
concealed installation is adopted, 1# metallic pipe can be used (Refer to Figure 44).
4. No matter if surface mounting or concealed mounting is selected, it is required to drill 2 holes (in the
same level) which distance shall be the same as the distance (60mm) of installation holes in the
bottom plate of the wire controller. Then insert a wood plug into each hole. Fix the bottom plate of the
wire controller to the wall by using the two holes. Plug the control wire onto the control panel.
Lastly install the panel of the wire controller.
Caution:
During the installation of the bottom plate of the wire controller, pay attention to the direction of the
bottom plate. The plate's side with two notches must be at the lower position, and otherwise the panel of
the wire controller cannot be correctly installed.
