1.1.6 Drain Piping Work

)
Installation of Drainage Pipeline
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. (As shown in
Figure 1-1-9)
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.

Testing of Drainage System
After the electrical installation is completed, carry out the testing of the drainage system.
During the test, check if the water correctly flows through the pipelines. Carefully observe the joints to ensure
that there is no leakage. If the unit is to be installed in a new house, carry out testing before decorating the
ceiling.

Matters of Attention
The joint of Drainage Pipeline must not have leakage.
The Drainage Pipeline shall be installed with an inclining angel 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. (As shown in Figure 1-1-10)

1.1.7 Installation of air duct and round duct for duct-type unit
Caution:
The supply air duct, the return air duct and the fresh air duct must be covered with a layer of thermal insulation,
so as to avoid thermal leakage and condensation. Firstly apply liquid nail on the duct, and then attach the
thermal insulation cotton with a layer of tinfoil. Use the liquid nail cover to fix it. Lastly use tinfoil adhesive tape
to carefully seal the joints; other good thermal insulation materials can also be used.
The supply air duct and the return air duct shall be fixed to the prefabricated boards of the ceiling by using iron
