Installation Procedure
Installation Procedure
Main drainpipe
Centralized horizontal drainpipe
(more than 1/100 slope)
• If it is necessary to increase the height of the
drain pipe, install the drain pipe straight within
11.81 inch(300mm) from the drain hose port. If it is
raised higher than 21.65 inch(550mm), there may be
water leaks.
• 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.
• Install horizontally.
• Max. allowable axis gap.
• Max. allowable bending angle.
NOTE
• If a concentrated drain pipe is installed, refer to the
figure below.
