1.2.6 Drain Piping Work
1 Installation of Drainage Pipeline
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.
When shipped out from factory, both the Drainage outlets are blocked by rubber plugs.
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 1-2-9)
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.
