Sanyo RCS-KS2432AWD User Manual

■ Parts supplied with remote controller

See Table 1.

■ Remote controller installation guidelines

• Mount the remote controller 1 to 1.5 meters off the
floor where it can sense the average temperature of
the room.

• Do not mount the remote controller in a place
exposed to direct sunlight or where it is exposed to
outside air such as near a window.

• Do not mount the remote controller behind a curtain
or other object so that it is separated from the air cir­culation of the room.

• Mount the remote controller inside the room being air
conditioned.

• The remote controller should be mounted on a wall or
other surface vertically.

Room temperature sensors are separately incorporated
in both the indoor unit and the remote controller. Either
sensor can be used to sense the room temperature. The
indoor unit sensor is usually used.

If you wish the remote controller to sense the room tem­perature, press the SENSOR button with a ballpoint pen
or tool with a small tip.

■ How to install the remote controller

<NOTE 1> Do not twist the remote controller wire

with the power cord, or run them in the
same metal conduit, because this may
cause a malfunction.

<NOTE 2> Install the remote controller away from all

sources of electrical noise.

<NOTE 3> Install a noise filter or take other appro-

priate action if electrical noise affects the
power supply circuit of the unit.

• Use an electric junction box (supplied locally) for
embedded mounting of the remote controller.

• For surface mounting on the wall, see Fig. 2.

1. Insert a screwdriver or the like in the groove on the

lower side of the remote controller to pry off the
back case. (See Fig. 3)

2. Use the 2 supplied M4 × 25 machine screws for

embeded mounting or M4 × 25 tapping screws for
surface mounting to secure the remote controller
back case. Prior to mounting, clear the cutouts in
the back case corresponding to the holes in the
wall box using a screwdriver or the like. Use the
spacers and take care not to tighten the screws
excessively. If the back case will not seat properly,
cut the spacers to a suitable thickness.

3. Connect locally supplied 3-core lead wires to the

lead wires from the remote controller. (See “How to
wire the remote controller.”)

(The remote controller will be damaged if
220/240V AC is applied.)

4. Hook the remote controller to the tabs of the back

case and mount it.

How to connect the harness (supplied parts)

1. Turn off the power, and remove the grille.

2. Remove the screws of the electrical box and

remove its cover.

3. Pull out the indoor unit controller (PCB ass’y).

(Fig. 6 on next page)

4. Pull out the lead wire that connects the remote con-

trol receiver to CN11 of the controller (PCB ass’y).
(Fig. 5 on next page)

5. Plug the socket of the supplied wire harness onto

CN11.

6. Bind the wire harness and the inter-unit lead wires

together, and route them. Fasten them under the
electrical box with the clamp. Then, pull them out
from the back of the indoor unit.
If required, connect the lead wire (field supply, max.
10 m). (Fig.4)
Use the supplied wire joints (6 pcs.) to connect the
lead wire. (See the connection diagram as shown at
right.)

■ How to test run the air conditioner

1. Switch on the power source.

2. Press the ON/OFF button on the remote control unit
once.

3. Set the operation selector switch of the indoor unit
to the TEST position. This starts the fan, producing
uncooled forced air. (Fig. 7)

4. After 3 minutes, the system shifts into cooling oper­ation, and cool air will start to be felt. Cooling oper­ation with the switch at the TEST position is unaf­fected by the room temperature.

5. After stopping the test run, turn the operation selec­tor switch of the indoor unit to the OFF position
once, then move to ON position. (Fig. 7)

6. Press the ON/OFF button on the remote control unit
to stop the air conditioner.

If the unit does not operate and the OPERATION lamp
on the unit is blinking after going through the proce­dure, check the wiring between the units.
