0 - 45°
* Length of supplied drain hose = 140 mm
● 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.
(Fig. 3-9)
● 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. 3-10)
● Provide insulation for any pipes that are run indoors.

3-5. 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) Slowly pour about 500 cc of water into the drain pan to
check drainage. (Fig. 3-11)

(3) Short the check pin (CHK) on the indoor control board and
operate the drain pump. Check the water flow through the
transparent drain pipe and see if there is any leakage.
(4) When the check of drainage is complete, open the check
pin (CHK) and remount the tube cover.
CAUTION
Be careful since the fan will start when you short the pin on
the indoor control board.

4. ELECTRICAL WIRING

4-1. General Precautions on Wiring

(1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring closely
Fig. 3-8
following the wiring diagram.
(2) Circuit breaker must be incorporated in the fixed wiring in
accordance with the wiring regulations. The circuit breaker
must be an approved 10-16 A, having a contact separation
in all poles.
(3) To prevent possible hazards from insulation failure, the unit
must be grounded.
(4) Each wiring connection must be done in accordance with
the wiring system diagram. Wrong wiring may cause the
unit to misoperate or become damaged.
(5) Do not allow wiring to touch the refrigerant tubing,
Fig. 3-9
compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be very
dangerous. The manufacturer will accept no responsibility
for any damage or misoperation that occurs as a result of
such unauthorized changes.
(7) Regulations on wire diameters differ from locality to
locality. For field wiring rules, please refer to your LOCAL
ELECTRICAL CODES before beginning.
You must ensure that installation complies with all relevant
rules and regulations.
(8) To prevent malfunction of the air conditioner caused by
Fig. 3-10
electrical noise, care must be taken when wiring as follows:
● The remote control wiring and the inter-unit control wiring
should be wired apart from the inter-unit power wiring.
● Use shielded wires for inter-unit control wiring between units
and ground the shield on both sides.
(9) If the power supply cord of this appliance is damaged,
it must be replaced by a repair shop designated by the
manufacturer, because special-purpose tools are required.
