7-7-3. In Case of Power Failure during the
Timer Operation
(2) If OFF-TIMER operation is reserved without
setting of Auto Restart operation, the reservation
is cancelled with power failure. (The OPERATION
lamp on the main unit goes on and off to inform of
power failure.) In that case, try to reserve OFF-
TIMER operation. When Auto Restart operation
is set, OFF-TIMER reservation is also cancelled
with power failure.
(1) If ON-TIMER operation is reserved with setting of
Auto Restart operation, it is cancelled with power
failure. (The OPERATION lamp on the main unit
goes on and off to inform of power failure.) In that

8-1. Safety Cautions
For general public use
Power supply cord of parts of appliance for Outdoor use shall be more than polychloroprene sheathed flexible
cord (design H05 RN-F), or cord designation 245 IEC 57.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAINS SUPPLY.
This appliance must be connected to the mains by means of a circuit breaker or a switch with a contact
separation of at least 3 mm.
If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible after
installation. The plug must be disconnected from the power supply socket in order to disconnect the appliance
completely from the mains.
DANGER
` FOR USE BY QUALIFIED PERSONS ONLY.
` TURN OFF MAIN POWER SUPPLY AND BREAKER BEFORE ATTEMPTING ANY ELECTRICAL WORK.
MAKE SURE ALL POWER SWITCHES AND BREAKER TURN OFF. FAILURE TO DO SO MAY CAUSE
ELECTRICAL SHOCK.
` CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED BY
WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.
` CHECK THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
` DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OF GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
` TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT
WELL AWAY (MORE THAN 2M.) FROM HEAT SOURCES SUCH AS RADIATORS, HEAT RESISTORS,
FURNACE, STOVES, ETC..
` WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY
CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R-22) WITH ANY OTHER GASEOUS BODY
INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE REFRIGERANT,

TROUBLESHOOTING PROCEDURES :
• Following details of “What to be pre-checked first”, make sure of the basic items.
• When there is no trouble corresponding to above, check in detail the faulty parts following “How to judge
faulty parts by symptoms” later.
9-1-2. Incorrect Cable Connection between
Indoor and Outdoor Units
9-1. What to be Prechecked First
9-1-1. Power Supply Voltage
The indoor unit is connected to the outdoor unit with 3
cables. Make certain that the indoor and outdoor units
have been connected properly, with terminals assigned
the same numbers wired to each other. If the connec-
tors are not connected as specified, the outdoor unit
will not operate normally.
The line voltage must be AC 220/230/240V. If the line
voltage is not within this range, this air conditioner
may not work normally.

9-1-3. Misleading but Good Operations
(Program Controlled Operation)
The microcomputer performs the operations listed in
Table 9-1-1 to control the air conditioner. If a claim is
made on the operation, check whether it corresponds
to the contents in the Table 9-1-1. If it does, it is an
indispensable operation for the control and mainte-
nance of the air conditioner: it is not a failure of the
unit.
