3-3. Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain
and use the supplied hose band to prevent water leaks.
The PVC pipe must be purchased separately.
CAUTION
O
Do not use adhesive tape at the drain connection port on
the indoor unit
O
Insert the drain pipe until it contacts the socket, and then
secure it tightly with the hose band.
O
Do not use the supplied drain hose bent at a 90° angle.
(The maximum permissible bend is 45°.)
O
Tighten the hose clamps so their locking nuts face
upward. (Fig. 3-8)
Hose clip (Accessory)
Heat insulator (Local supply)
(The thickness must be at
least 8 mm.)
It may be required to take off this part for checking
or servicing the drain up motor. Please do not glue.
Make sure that there is no clearance here.
(2) After connecting the drain pipe securely, wrap the supplied
packing and drain pipe insulator around the pipe, then secure it
with the vinyl clamps . (Fig. 3-9)
Drain insulator (supplied)
NOTE
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. (Fig. 3-10)

O
Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to fl ow
backward and leak when the unit is not operating.
(Fig. 3-12)
Prohibited
O
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. 3-13)

3-4. Connecting Duct to indoor Unit
(1) Install the duct (local supply) for the Dimension of the
installation hole.
Use M5 self-tapp Screws for installation see the Figure 3-2.
(2) The duct connection of the air outlet needs thermal insulation.

NOTE
•
Select an air-intake grille with a filter at a local shop.
•
To get clean air and to extend the service life of the air
conditioner, an air filter must be installed in the air intake. For
installation and cleaning the air filter, consult your dealer or
service center.
