1. SAFETY PRECAUTIONS
Let the customer keep this installation manual because it is needed•
when the air conditioner or receiver unit is serviced or moved.
WARNING
This mark indicates procedures which, if improperly
performed, might lead to the death or serious injury of
the user.
Never touch electrical components immediately after the power supply•
has been turned off. Electrical shock may occur. After turning off
the power, always wait 5 minutes or more before touching electrical
components.
For the air conditioner to operate satisfactorily, install it as outlined in•
this installation manual.
Installation work must be performed in accordance with national wiring•
standards by authorized personnel only.
Do not cut, shorten, or extend the cable in the standard parts.•
Do not turn on the power until all installation work is complete.•
CAUTION
This mark indicates procedures which, if improperly
performed, might possibly result in personal harm to
the user, or damage to property.
Do not wire the receiver unit wire together with or parallel to the•
connection cables, transmission cables, remote controller cables, bus
cable and power supply cables of the indoor and outdoor units. It may
cause erroneous operation.
Do not install the receiver unit cable near a source of electromagnetic•
waves.
Do not install where there is the danger of combustible gas leakage.•
Do not install near heat sources, steam.•

5. SELECTING THE INSTALLATION LOCATION
Consult the customer and determine the installation location according to the
following:
(1) The receiver unit cable can be extended up to 10m. (To extend the
wiring, purchase the optional receiver unit wire C.)
(2) The signal reception angle of the receiver unit is shown in the gures
below.
(3) Do not install the receiver unit near a uorescent light. (The unit must be
at least 1m away from a light source.)
(4) Do not install the receiver unit where it will be exposed to direct sunlight.
(5) Do not install the receiver unit where it will be exposed directly to the

hands.
When xing the wiring, be careful to avoid touching the edge of the •
indoor unit or the control box.
Install the remote controller wires so as not to be direct touched with•
your hand.
Make sure to use and roll an insulation tube of more than 1 mm thick•
at the connection point of the receiver unit wire A and the receiver unit
wire B.

controller is operating an air conditioner other than the one you wish to
set, change the signal code of the remote controller to operate only the air
conditioner you wish to set (4 selections possible).
When two or more air conditioners are installed in a room, please contact
your retailer to set the individual air conditioner signal codes.
Selecting the Remote Controller Signal Code
Use the following steps to select the signal code of the remote controller.
(Note that the air conditioner cannot receive a signal code if the air
conditioner has not been set for the signal code.)
1Press the START/STOP button until only the clock is displayed on the
remote controller display.
2Press the MODE button for at least 5 seconds to display the current
signal code (initially set to ).

10°C HEAT
If no buttons are pressed within 30 seconds after the signal code is
displayed, the system returns to the original clock display. In this case,
start again from step 1.
The air conditioner signal code is set to A prior to shipment. Contact your
retailer to change the signal code.
The remote controller resets to signal code A when the batteries in the
remote controller are replaced. If you use a signal code other than signal
code A, reset the signal code after replacing the batteries.
If you do not know the air conditioner signal code setting, try each of the
signal codes ( ) until you nd the code which operates the air
conditioner.
12. TEST OPERATION
The outdoor unit may not operate depending on the room temperature. In
this case, press the test run button on the remote controller while the air
conditioner is running. (Point the transmitter section of the remote controller
