2.2.11 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 Fig.46.
Fig.15
Cautions:
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.
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 Fig.46).
3) Wrapped pipe must be fixed to wall using pipe clamps.
Cautions:
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.
2.2.12 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.
