3-3. Installing the Drain Pipe
Prepare standard hard PVC pipe (I.D. 20 mm) for the drain.
The PVC pipe must be purchased separately.
Indoor unit
Drain insulator(supplied)
Drain hole
Make sure the drain pipe has a downward gradient (1/100 or
more) and that there are no water traps.
● Do not install an air bleeder as this may cause water to
spray from the drain pipe outlet. (Fig. 3-9)

Prohibited
● 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 500 mm. Do not raise it any higher than
500 mm, as this could result in water leaks. (Fig. 3-10)
Good
● 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. 3-11)
Prohibited
● 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. 3-12)

3-4. Checking the Drainage
After wiring and drain piping are completed, use the following
procedure to check that the water will drain smoothly. For this,
prepare a bucket and wiping cloth to catch and wipe up spilled
water.
● Pour a glass of water into the drain plate.
● Ensure that water flows out from drain hose of the indoor unit.
