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 breaken.
•
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.
Caution:
•
When connecting the indoor unit with the refrigerant pipe, do not pull the big and small joints of the
indoor unit forcefully, so as to prevent the capillary of the indoor unit and other pipes from breaking
and leaking.
•
The refrigerant pipe shall be supported by proper bracket. The weight of the pipe shall not be
withstand by the unit.
No gap
