Drain tubing connections
Do not connect the drain directly to sewage tubes that
smell of ammonia. The ammonia in the sewage might
enter the indoor unit through the drain tubes and corrode
the heat exchanger.
Do not twist or bend the drain hose, so that excessive
force is not applied to it.
This type of treatment may cause leaking.
After tubing work is finished, check drainage flows
smoothly.
Gradually insert approximately 1000 cc of water into
the drain pan to check drainage in the manner described
below.
Gradually pour approximately 1000 cc of water from
the outlet hole into the drain pan to check drainage.
Check the drainage.
