2 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.
3 Matters of Attention
The joint of Drainage Pipeline must not have leakage.
The Drainage Pipeline shall be installed with an inclining angel of 510°, 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 supports. The joints of the pipes must be sealed by glue so as to avoid leakage.
