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.
3. Use adhesive tape to wrap the pipes:
(1) 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.
(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. 8.15).
(3) Wrapped pipe must be fixed to wall using pipe clamps.
CAUTION
(1) Do not wrap the protective tape too tight, otherwise the efficiency of thermal insulation may be
decreased. Ensure that the condensate drainage flexible tube is separated 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.
