NOTICE
Do NOT install the unit tilted. Possible consequence: If
the unit is tilted against the direction of the condensate flow
(the drain piping side is raised), the float switch might
malfunction and cause water to drip.

Guidelines when installing the drain
piping
Make sure condensation water can be evacuated properly. This
involves:
▪ General guidelines
▪ Connecting the drain piping to the indoor unit
▪ Checking for water leaks
General guidelines
▪ Pipe length. Keep drain piping as short as possible.
▪ Pipe size. Keep the pipe size equal to or greater than that of the
connecting pipe (vinyl pipe of 25 mm nominal diameter and
32 mm outer diameter).
▪ Slope. Make sure the drain piping slopes down (at least 1/100) to
prevent air from being trapped in the piping. Use hanging bars as
shown.
