he edge of the air intake pipe must be at least 150mm away from the wall. The air intake must be covered
with lter.
Silencing and shock absorption shall be considered in the design and installation of the air pipes.
Additionally, the noise source must be far away from where people stay. The air intake shall not be located
above the place where users stay (ofces and rest places, etc.).
8.2.5 Installation of Drainage Pipeline
1.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 Fig.43)
2. 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.
3. When shipped out from factory, both the Drainage outlets are blocked by rubber plugs.
4. When connecting the drainage pipe with the unit, do not apply excessive force to the pipeline at the side
of the unit. The xing position of the pipeline shall be near the unit.
5. 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 exible drainage tube and tighten it
with thread loop. Never use adhesive to connect the drainage hole and the exible drainage tube.
6. 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.

Cautions: The joint of Drainage Pipeline must not have leakage.
8.2.7 Testing of Drainage System
1.After the electrical installation is completed, carry out the testing of the drainage system.
2.During the test, check if the water correctly ows 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.
