Precautions:

1. The preparation of all pipes (connecting pipes and drainage pipes) and cables (connecting lines of
wire controller, indoor unit and outdoor unit) must be ready before the installation, so as to achieve
smooth installation.

2. Drill an opening on the ceiling. Maybe it is required to support the ceiling to ensure the evenness of it
and avoid the vibration of it. Consult with the user or a construction company for details.

3. In case the strength of ceiling is not enough, use angle iron sections to set up a beam support. Place
the unit at the beam and fix it.

Level Check of the Indoor Unit

After the indoor unit is installed, it is required to check the level of the whole unit. The unit must be placed
horizontally, but the condensate pipe shall be installed obliquely, so as to facilitate the drainage of

condensate.

Cautions:

 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.

 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.

 The design and installation of air pipes must be in conformity with the relevant state engineering

criteria.

 The edge of the air intake pipe must be at least 150mm away from the wall. The air intake must

be covered with filter.

 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.).

Installation of Condensate Pipe

(1) The condensate pipe shall be installed with an inclining angel of 5～10°, so as to facilitate the

drainage of condensate. The joints of the condensate pipe must be covered by thermal
insulation materials to avoid generation of exterior condensate. (As shown in Figure 23)

(2) A condensate outlet is located at both the left and right sides of the indoor unit. After selecting

one condensate 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 condensate outlets are blocked by rubber plugs.

Cover board

Figure 37 Thermal Insulation of Condensate Pipe

Caution: The joint of condensate pipe must not have leakage.

Design of Drainage Pipeline

(1)The pipeline must always have an inclining angle (1/50～1/100), so as to prevent the pipeline from

forming projection and water flow elbow.

(2) 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.

(3) 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

22

Unit Installation Instructions Installation of Condensate Pipe

and the flexible drainage tube.

(4) 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

（1） After the electrical installation is completed, carry out the testing of the drainage system.

(2) 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.
