indoor unit to ensure that any condensate water is correctly
drained outside.

Attach the drain hose to the drain hose port with an adhesive for
PVC and tape to prevent water leaks, then secure the hose with
a band etc..(The band is not supplied with the air conditioner.)
2) Install the drain hose so that its length can be as short as
possible. Internal diameter of the drain hose should be the
same or slightly bigger than the external diameter of the
drain hose port.

Check that the indoor unit is level with the ceiling by using the leveler.
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.

If it is necessary to increase the height of the drain hose
somewhat, the portion directly after 30cm. If it is raised
higher than 55cm, there can be 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.
