9 - 1 Drainage Instructions
Install the drain piping
•
The drain pipe should be short with a downward slope and should prevent the formation of air pockets.
•
When extending the drain hose, use a commercially available drain extension hose, and be sure to insulate the extended section of the drain hose which is indoors.
•
Make sure the diameter of the piping is the same as the piping (hard vinyl chloride, nominal diameter 13mm) or bigger.
•
When directly connecting a hard vinyl chloride pipe joint (nominal diameter 13mm) to the drain hose connected to the indoor unit (i.e. for embedded piping,
etc.), use a commercially available hard vinyl chloride pipe joint (nominal diameter 13mm).
Make sure the drain hose is at a
downward slope.
Make sure the tip does not go
underwater even when water is added.
