Do not install air bleeding tubes, as this may
cause water to spray from the drain tube outlet.
Check that the indoor unit is level with the ceiling by using the leveler.
If it is necessary to increase the height of the drain hose
somewhat, the portion directly after 30cm/1ft. If it is raised
higher than 50cm/1 ft , there can be water leaks.

Do not give the hose and upward gradient after the
connection port. This will cause water to flow backwards
when the unit is stopped, resulting in water leaks.
Do not apply force to the piping on the unit side when
connecting the drain hose. The hose should not be
allowed to hang loose from its connection to the unit.
Fasten the hose to a wall, frame or other support as
close to the unit as possible.
