Caution
Drain piping connections
Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the
sewage might enter the indoor unit through the drain pipes and corrode the heat exchanger.
Keep in mind that it will become the cause of getting drain pipe blocked if water collects on drain pipe.

(1) Install the drain piping. (Refer to Fig. 16)
The drain pipe should be short with a downward slope and should prevent air pockets from forming.
Watch out for the points in the figure 16 when performing drain work.
When extending the drain hose, use a commercially available drain extansion hose, and be sure to
insulate the extended section of the drain hose which is indoors.
(Refer to Fig. 17)
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
choride pipe joint (nominal diameter 13mm).
(Refer to Fig. 18)
Make sure the drain
hose is at a downward
slope
Make sure the tip does
not go underwater even
when water is added.

and make ing sure the water flows smoothly
out of the drain hose.
