.2.4 Installation of Rectangular Air Pipe
Fig.10
Cautions:
①
The air supply pipe, the air intake pipe and the fresh air pipe must be covered with a layer of
thermal insulation, so as to avoid thermal leakage and condensation. Firstly apply liquid nail on the
pipes, 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.
②
The air supply pipes and the air intake pipes shall be fixed to the prefabricated boards of the
ceiling by using iron supports. The joints of the pipes must be sealed by glue so as to avoid
leakage.
③
The design and installation of air pipes must be in conformity with the relevant state
engineering criteria.
④
The edge of the air intake pipe must be at least 150mm away from the wall. The air intake must
be covered with filter.
⑤
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 (offices and rest places, etc.)
2.2.5 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.39)
(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 fixing 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 flexible
