Air ventilation
Check that the indoor unit is level with the ceiling by using the leveler.
Air ventilation
Ceiling
Install air ventilation to drain condensate water smoothly.
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.
Under gradient
Ceiling
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.

If it is necessary to increase the height of the drainpipe,
install the drainpipe straightly within 300 mm from the
drain hose port. If it is raised higher than 550 mm, there
can be water leaks.
