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 20 mm nominal diameter and
26 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.
