Installation of Drainage Pipeline
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 1-3-7)
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.

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.
