〈 PRECAUTIONS 〉
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.
• Select central drain piping of proper size according to the
capacity of the connected unit.
(2) After piping work is finished, check drainage flows
smoothly.
• Gradually insert approximately 1 L of water into the drain
pan to check drainage in the manner described below.
