Drain piping connections
Do not connect the drain pipes directly to sewage pipes
to avoid ammonia odor. The ammonia in the sewage
might enter the indoor unit through the drain pipes
and corrode the heat exchanger.
Do not twist or bend the drain hose, doing so applies
excessive force applied on it and may also cause
leakage.
After piping work is finished, check if drainage flows
smoothly.
Gradually pour approximately 1000 cc of water from
the outlet hole into the drain pan to check drainage flow.
