UNIT INSTALLATION INSTRUCTIONS

Installation of drainage pipeline

•The Drainage Pipeline shall be installed with an inclining angle of 5~10°, so as to facilitate the drainage of condensate. The joints of the Drainage Pipeline must be covered by thermal insulation materials to avoid generation of exterior condensate.

•A Drainage outlet is located at both the left and right sides of the indoor unit. After selecting one Drainage outlet, the other outlet shall be blocked by rubber plug. Bundle the blocked outlet with string to avoid leakage, and also use thermal insulation materials to wrap the blocked outlet.

•When shipped out from factory, both the Drainage outlets are blocked by rubber plugs.

•When connecting the drainage pipe with the unit, do not apply excessive force to the pipeline at the side of the unit. The fixing position of the pipeline shall be near the unit.

•Purchase general-purpose hard PVC pipe locally to be used as the drainage pipeline. When carrying out connection, place the end of the PVC pipeline into the drainage hole. Use flexible drainage tube and tighten it with thread loop. Never use adhesive to connect the drainage hole and the flexible drainage tube.

•When the laid drainage pipe is used for multiple units, the common pipe shall be about 100mm lower than the drainage outlet of each set of unit. A pipe with thicker wall shall be used for such purpose.

UNIT INSTALLATION INSTRUCTIONS

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.

Installation of protective layer of refrigerant pipe

1To 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.

2The 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.

No gap

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.
