3 INSTALLATION LOCATION OF SIGNAL
RECEIVING UNIT
• Do not install in a location where the air contains oil mist, such as in a kitchen or factory.
• Do not install next to a window, or in any other location directly exposed to sunlight and
outside air.
• Do not install nearby devices which can be expected to produce electrical noise, such as
elevators, automatic doors, and industrial sewing machines.
• If the Signal receiving unit is installed near a rapid-start type or inverter-type fluorescent
lamp (a lamp which does not include a glow lamp), it may not be possible to receive the
wireless remote controller signal in some cases. In order to prevent interference from
fluorescent lamps, leave a minimum of 6’7” (2 m) between the Signal receiving unit and
the fluorescent lamps, and install the Signal receiving unit in a location where it can receive
the wireless remote controller signal when the fluorescent lamps are lit.

4 HOW TO INSTALL THE SIGNAL RECEIVING
UNIT
NOTE
• To avoid malfunction of the remote controller, do not assemble or run remote control
wiring together with the power cables, and do not enclose them in the same metal
conduit.
• When the power unit induces electrical noise, it is recommended that a noise filter or the
like be installed.
For flush mounting into a wall, install the Signal receiving unit in a metal
switch box (field supply) that has been recessed into the wall in advance.
1. Insert a flathead screwdriver or similar
tool into the notch, and remove the
face plate.

2. Fix the Signal receiving unit with 2
∅0.16” (4 mm) screws provided. Do
not overly tighten, and use the
provided spacers. If the Signal
receiving unit does not fit in the wall,
cut spacers to adjust the clearance.
3. Connect the Signal receiving unit

extended from the indoor unit.
(Refer to the section on Signal receiving unit wiring.)
Be sure to determine the correct terminal numbers on the indoor unit when wiring the Signal
receiving unit. The remote controller will be damaged if high voltage (such as 208/230 VAC) is
applied.
4. Reattach the face plate.
When using exposed mounting for the Signal receiving unit, install onto
a wall where the Signal receiving unit can be attached.
1. Insert a straight blade screwdriver or similar
tool into the groove on the bottom of the
Signal receiving unit. Pry open with the
screwdriver and remove the lower case.

If the separate Signal receiving unit is installed on the ceiling, use the
provided ceiling mounting bracket for installation.
1. Insert a screwdriver or similar tool into the notch at the
bottom to remove the Signal receiving unit face plate.
2. Cut a section out of the ceiling along the provided paper
pattern (3.7” x 2” (95 x 51 mm)).
3. Pass the wire through the provided mounting bracket and
insert the bracket into the installation hole. (Fig. D)

4. Use bracket parts (A) and (B) to securely grip the ceiling
material. (Fig. E)
5. Connect the Signal receiving unit wire (2-core) to the wire
from the indoor unit. (Refer to “Wiring the Signal receiving
unit.”) Check the terminal number on the indoor unit
before wiring the Signal receiving unit and be sure not to
wire incorrectly. (The unit will be damaged if high voltage,
such as 208/230 VAC, is applied.)
6. Adjust the provided spacers so that they are several
millimeters larger than the thickness of the ceiling
material. Pass the 2 supplied screws (0.16” x 1.6” (M4 x
40 mm)) through the spacers and tighten them enough to
hold the Signal receiving unit in place.
7. Return parts (A) and (B) through the gap between the
ceiling and Signal receiving unit so that they are
contained in the openings. Then tighten the screws.
Do not tighten the screws excessively. This may result in
damage or deformation of the case.
Tighten to the point where the Signal receiving unit can be
moved slightly by hand. (Fig. F)

6 REQUIREMENT
The control by two remote controllers is enabled by installing the wireless remote controller
with the wired remote controller for an indoor unit.
(Max. 2 remote controllers of wireless or wired are insatiable.)
“2-remote controllers” controlling means that one or multiple units are operated by the
multiple remote controllers.
NOTE
1. Upon confirmation of the terminal numbers of the indoor unit, connect the remote
controller cables without miscabling. (If applied AC 208/230 Volt, damage the unit.)
2. The multiple wireless remote controller kits cannot concurrently be used for an indoor
unit.
3. When installing simultaneously the wireless remote controller with the wired remote
controller, set one of them as the sub remote controller.
• When setting the wired remote controller as the sub, exchange the address connector
at the rear of P.C. board of wired remote controller from master to sub remote
controller.
• When setting the wireless remote controller as the sub, turn the switch of wireless
remote controller Signal receiving unit from RCU: MAIN to RCU:SUB.
To operate an indoor unit by 2 remote controllers
The indoor unit is operated if either wireless or wired remote controller is set as MAIN or SUB
remote controller.

• The room temperature sensor is set to the indoor unit side as factory default.
To select the sensor in the remote controller, push the SENSOR button (figure below)
inside of the remote controller cover and check “ ” disappears from LCD.
NOTE
If the room temperature data from the remote controller
is not transmitted to the unit for 10 minutes or more, the
sensor at indoor unit side is automatically selected
even if the sensor at the remote controller side is
selected.
Fix the remote controller toward the unit as possible.

8 HOW TO SET THE ADDRESS SWITCH
• When the multiple Signal receiving units are installed in the same room, an address can
be set to prevent cross communication.
• When replacing the battery and pushing ACL button, the address of the remote controller
becomes [ALL] and the Signal receiving unit is enabled to receive signal regardless of
setting of address switch of the operation section.
• For selecting of the remote controller address, refer to Owner’s Manual.
• Change the address of the Signal receiving unit by removing screws of P.C. board cover
of the Signal receiving unit. After then, fix the cover with screws using a clamp.

14 TEST RUN
Before test run
• Before turning on the power supply switch, carry out the following procedure.
1 Using 500V-megger, check 1MΩ or more exists between the terminal block 1 to 3 and the earth.
If 1MΩ or less is detected, do not run the unit. Do not apply to the remote controller circuit.
2 Check the valve of the outdoor unit being opened fully.
• To protect the compressor at activation time, leave power-ON for 12 hours or more be for
operating.
How to conduct a TEST RUN
1. Remove the face plate from the Signal receiving unit.
Set the “TEST RUN” switch to the “TEST RUN” position.
2. Push the button on the wireless remote controller to start the
operation of the air conditioner.
The , , and lamps each light under test running.
The temperature cannot be set by the wireless remote
controller with the “TEST RUN” switch is set to the “TEST RUN”
position.
3. Operate the air conditioner in the “heating”, “cooling”, or “fan
only” mode during test running.
The outdoor unit will not operate for approximately 3 minutes
after the air conditioner has been turned on or off.
CAUTION
Do not set the switch to the “TEST RUN” position other than for test running.
The air conditioner may be damaged if this switch is set to the “TEST RUN” position for
normal operation.
(The Signal receiving unit automatically turns off the air conditioner 60 minutes after the
switch has been set to the “TEST RUN” position to prevent continuous test running.)
