Installation of protective layer of refrigerant pipe
. To avoid generation of condensate on the refrigerant pipe and avoid leakage, the refrigerant
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 to be no gap between the refrigerant
pipe joint and the wall of the indoor unit.
3. Use adhesive tape to wrap the pipes:
• Use adhesive tape to bundle the refrigerant pipe and the cables
together. To prevent condensate from overflowing out from the
drainage pipe, separate the drainage pipe from the refrigerant
pipe and the cables.
• 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.
• Wrapped pipe must be fixed to wall using pipe clamps.
Caution:
• After the pipes are wrapped by protective materials, never bend the pipes to form very small
angle, and otherwise the pipes may be cracked or broken.
• Do not wrap the protective tape too tight, and otherwise the efficiency of thermal insulation
may be decreased. Make sure that the drainage pipe is separate from the bundled pipes.
• After the protective work is completed and the pipes are wrapped, use seal material to seal the
hole in the wall, so as to prevent rain and wind from entering the room.
Position and method of installing wire controller
1. 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.
2. If the control wire between the wire controller and the indoor unit is surface-mounted, use #
metallic pipe and make matching recess in the wall (Refer to Figure ); If concealed installation
is adopted, # metallic pipe can be used (Refer to Figure 2).
3. 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.
• The communication distance between the main board
and the wire controller is 8 m.
• The wire controller shall not be installed in a place
where there is water drop or large amount of water
vapor.
