grille.
Make sure condensation water can be evacuated properly. This involves:
▪ General guidelines
▪ Connecting the drain piping to the indoor unit
▪ Checking for water leaks
▪ Pipe length. Keep drain piping as short as possible.
▪ Pipe size. If drain hose extension or embedded drain piping is required, use
appropriate parts that match the hose front end.
NOTICE

Install the drain hose with a downward slope.
▪
Traps are NOT permitted.
▪
Do NOT put the end of the hose in water.

of the extension hose.
