Drainage pipe installation
Install the drainage pipe as shown below and take measures against condensation. Improperly installation
could lead to leakage and eventually wet furniture and belongings.
6.1
Installation principle
Ensure at least 1/100 slope of the drainage pipe
Adopt suitable pipe diameter
Adopt nearby condensate water discharge
6.2
Key points of drainage water pipe installation
6.2.1
Considering the pipeline route and elevation
Before installing condensate water pipeline, determine its route and elevation to avoid intersection with
other pipelines and ensure slope is straight.
6.2.2
Drainage pipe selection
The drainage pipe diameter shall not small than the drain hose of indoor unit
According to the water flowrate and drainage pipe slope to choose the suitable pipe, the water flowrate
is decided by the capacity of indoor unit.
