3-22. Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 26 mm) for the drain
and use the supplied hose band to prevent water leaks.
(Fig. 3-64)
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you to check
drainage.

CAUTION
●
Attach so that the hose band fastener is on the side of the
drain port. (Fig. 3-64)
●
Attach the hose bands so that each is approximately 5 to 25
mm from the end of the supplied drain hose. (Fig. 3-64)
●
Do not use adhesive at the drain connection port on the
indoor unit.
●
Insert the drain pipe until it contacts the socket, as
shown in the figure above, then secure it tightly with the
hose band.
●
Do not use the supplied drain hose bent at a 90° angle.
(The maximum permissible bend is 45°.)
● Tighten the hose clamps so their locking nuts face in the
horizontal direction.
●
Make sure that the drain port is not a downward gradient
from the joint section (may lead to abnormal noise).
N OTE
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. 3-65-1)

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. 3-65-2)
At least 1/100

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. 3-65-3)
Upward gradient
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
Unit:mm
close to the unit as possible. (Fig. 3-65-4)

3-23. 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.
(1) Connect power to the power terminal board (R, S
terminals) inside the electrical component box.
(2) Remove the eyelet cap and through the opening, slowly
pour about 500 cc of water into the drain pan to check
drainage.
(3) Short the check pin (CHK) on the indoor control board and
operate the drain pump. Check the water flow through the
transparent drain port and see if there is any leakage.
CAUTION
Be careful since the fan will start when you short the pin on
the indoor control board.
(4) When the check of drainage is complete, open the check
pin (CHK) and remount the insulator and drain cap onto
the drain inspection port.

3-24. Increasing the Fan Speed
■ For Short Circuit Connection
● The standard (before shipment) external static pressure is
shown in the table below.
● When using with a higher static pressure, it is necessary to
change to the high static pressure mode.

Type
Standard (Pa)
High static pressure (Pa)
When using with high static pressure mode, set the indoor unit
control board as shown in Fig. 3-67.
Fig. 3-65-3
Indoor control board
Follow the below procedure while the unit is turned off.
(1) Open the cover of the electrical box and confirm that it is the
indoor unit control board.
Fig. 3-65-4
(2) Connect the short circuit connector to the short circuit pin
TP3 (2P: Yellow) of the indoor unit control board.
●
In case of wired remote control setting, do not use the short
circuit connector.
