CAUTION
Check that the indoor unit is level with the ceiling by using the leveler.
Do not install air bleeding tubes, as this may cause water to spray from the drain tube outlet.
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 85 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.
Upward gradient
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.
