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 piping and corrode the
heat exchanger.

Do not twist or bend the drain hose (2), so that excessive force is not applied to it.
(This type of treatment may cause leaking.)
!
If you are using central drain piping, follow the procedure outlined in the figure 10.
