Drainpipe and drain hose installation
Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is drained
correctly outside.
1. Fix the flexible hose to the drainpipe.

• If it is necessary to increase the height of the drainpipe,
install the drainpipe straightly within 300mm(11.81")
from the drain hose port. If it is raised higher than
550mm(21.65"), 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.
