• If it is necessary to increase the height of the drain
pipe, install the drain pipe straight within 300 mm
from the drain hose port. If it is raised higher than 550
mm, there may be water leaks.
Drain hose
Band joint
• Do not give the hose an upward gradient beyond 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.
