▪ Make sure the ceiling opening is within its limits:
Minimum: 860 mm to be able to fit the unit.
Maximum: 910 mm to ensure enough overlapping between the
decoration panel and the suspended ceiling. If the ceiling
opening is bigger, add extra ceiling material.

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.
6.2.3 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).
