Tighten the provided metal clamp to
make sure that fifteen holes are able to
be seen at least.
Drainpipe and drain hose installation
Check that the indoor unit is level with the ceiling by using the leveler.
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.
Air ventilation
Ceiling
Install air ventilation to drain condensate water smoothly.
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.
Under gradient
Ceiling
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.
