• 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.
(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
chloride pipe joint (nominal diameter 13mm).
(Refer to Fig. 18)
(2) Make sure the drain works properly.
• After drain work is complete, perform a
drain check by opening the front panel,
removing the air filter , pouring water
into the drain pan, and making sure
water flows smoothly out of the drain
hose. (Refer to Fig. 19)
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.
