CAUTION
● If it is necessary to increase the height of the drain pipe,
the section directly after the connection port can be
raised a maximum of 64 cm. Do not raise it any higher
than 64 cm, as this could result in water leaks. (Fig. 3-9)
● Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating. (Fig.
3-10)

● Do not apply force to the piping on the unit side when
connecting the drain pipe. The pipe should not be
allowed to hang unsupported from its connection to the
unit. Fasten the pipe to a wall, frame, or other support as
close to the unit as possible. (Fig. 3-11)
● Provide insulation for any pipes that are run indoors.

(3) Prepare a standard hard PVC pipe (O.D. 26 mm) for the
drain and use the supplied drain hose and hose band to
prevent water leaks.
The PVC pipe must be purchased separately. The unit's
transparent drain port allows you to check drainage.
CAUTION
● Insert the drain pipe until it contacts the socket as shown
in the diagram, then secure it tightly with the hose band.
● Do not use adhesive when connecting the supplied hose.
(4) Installing the drain hose
● To install the drain hose, first place 1 of the 2 hose
bands over the unit drain port and the other hose band
over the hard PVC pipe (not supplied). Then connect
both ends of the supplied drain hose.
● On the unit drain side, grasp the hose band with pliers
and insert the drain hose all the way to the base.
● If other commercially available hose bands are used, the
drain hose may become pinched or wrinkled and there
is danger of water leakage. Therefore be sure to use the
supplied hose bands. When sliding the hose bands, be
careful to avoid scratching the drain hose.
● Do not use adhesive when connecting the supplied
drain hose to the drain port (either on the main unit or
the PVC pipe).
Reasons: 1. It may cause water to leak from the connection.
Since the connection is slippery just after the
adhesive has been applied, the pipe easily slips
off.
2. The pipe cannot be removed when maintenance
is needed.
● Wrap the hose with the supplied drain hose insulation and
use the 4 twist ties so that the hose is insulated with no gaps.
● Do not bend the supplied drain hose 90° or more. The
hose may slip off.
Upward gradient prohibited
Support pieces
CAUTION
● Attach so that the hose band fastener is on the side of
the drain port.
● Attach the hose bands so that each is approximately 5
to 25 mm from the end of the supplied drain hose.

Make sure the drain pipe has a downward gradient (1/100 or
more) and that there are no water traps.
CAUTION

● Do not install an air bleeder as this may cause water to
spray from the drain pipe outlet.
● In cases where it is necessary to raise the height of
the drain piping, the drain piping can be raised to a
maximum height of 850 mm above the bottom surface
of the ceiling. Under no conditions attempt to raise it
higher than 850 mm above the bottom surface of the
ceiling. Doing so will result in water leakage.
● Do not use natural drainage.
● Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating.
● Do not apply force to the piping on the unit side when
connecting the drain pipe. The pipe should not be
allowed to hang unsupported from its connection to the
unit. Fasten the pipe to a wall, frame, or other support as
close to the unit as possible.
