HEAT & COOL MODEL (Reverse cycle)  
G When AUTO CHANGEOVER operation is selected, the air conditioner selects the  
appropriate operation mode (Cooling or Heating) in response to your rooms  
temperature.  
G When AUTO CHANGEOVER operation first selected, the fan will operate at very  
low speed for about one minute, during which time the unit detects the room  
conditions and selects the proper operating mode.  
G When the air conditioner has adjusted your rooms temperature to near the ther-  
mostat setting, it will begin monitor operation. In the monitor operation mode,  
the fan will operate at low speed. If the room temperature subsequently changes,  
the air conditioner will once again select the appropriate operation (Heating, Cool-  
ing) to adjust the temperature to the value set in the thermostat. (The monitor  
operation range is 4 °F relative to the thermostat setting.)  
G If the mode automatically selected by the unit is not what you wish, see page 6  
and select one of the mode operation (HEAT, COOL, DRY, FAN).  
*Heating:  
G Use to warm your room.  
G When Heating mode is selected, the air conditioner will operate at very low fan  
speed for about 3 to 5 minutes, after which it will switch to the selected fan set-  
ting. This period of time is provided to allow the indoor unit to warm up before  
beginning full operation.  
* During Heating mode:  
Set the thermostat to a temperature set-  
ting that is higher than the current room  
temperature. The Heating mode will not  
operate if the thermostat is set lower than  
the actual room temperature.  
G When the room temperature is very low, frost may form on the outside unit, and  
its performance may be reduced. In order to remove such frost, the unit will  
automatically enter the defrost cycle from time to time. During Automatic De-  
frosting operation, the OPERATION indicator lamp (red) will flash, and the heat  
operation will be interrupted.  
During Cooling/Dry mode:  
Set the thermostat to a temperature set-  
ting that is lower than the current room  
temperature. The Cooling and Dry modes  
will not operate if the thermostat is set  
higher than the actual room temperature  
(in Cooling mode, the fan alone will oper-  
ate).  
Cooling:  
G Use to cool your room.  
During Fan mode:  
You can not use the unit to heat and cool  
your room.  
Dry:  
G Use for gently cooling while dehumidifying your room.  
G You cannot heat the room during Dry mode.  
G During Dry mode, the unit will operate at low speed; in order to adjust room  
humidity, the indoor units fan may stop from time to time. Also, the fan may  
operate at very low speed when detecting room humidity.

vacuum cleaner, or by washing the filters in a solution of  
mild detergent and warm water. If you wash the filters,  
be sure to allow them to dry thoroughly in a shady place  
before reinstalling.  
G If dirt is allowed to accumulate on the intake filters, air  
flow will be reduced, lowering operating efficiency and  
increasing noise.  
G During periods of normal use, the intake filters should be  
cleaned every five weeks.  
When using the optional Air Cleaning Filter  
G Install the optional air cleaning filter set as instructed (installation instructions are furnished with the air cleaning filter set).  
G When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the

TROUBLESHOOTING  
Instructions relating to heating (*) are applicable only to HEAT & COOL MODEL(Reverse Cycle).  
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the elec-  
WARNING!  
trical breaker or disconnect the power supply plug, and consult authorized service personnel.  
Merely turning off the units power switch will not completely disconnect the unit from the power  
source. Always be sure to turn off the electrical breaker or disconnect the power supply plug to  
ensure that power is completely off.  
Before requesting service, perform the following checks:  
Symptom  
Problem  
See Page  
NORMAL  
FUNCTION  
Doesnt operate immedi-  
ately:  
G If the unit is stopped and then immediately started again, the com-  
pressor will not operate for about 3 minutes, in order to prevent  
fuse blowouts.  
G Whenever the electrical breaker is turned off then on again or the  
power supply plug is disconnected and then reconnected, the pro-  
tection circuit will operate for about 3 minutes, preventing unit  
operation during that period.  
Noise is heard:  
G During operation and immediately after stopping the unit, the  
sound of water flowing in the air conditioners piping may be  
heard. Also, noise may be particularly noticeable for about 2 to 3  
minutes after starting operation (sound of coolant flowing).  
G During operation, a slight squeaking sound may be heard. This is  
the result of minute expansion and contraction of the front cover  
due to temperature changes.  
*G During Heating operation, a sizzling sound may be heard occa-  
sionally. This sound is produced by the Automatic Defrosting op-  
eration.  
15  
Smells:  
G Some smell may be emitted from the indoor unit. This smell is  
the result of room smells (furniture, tobacco, etc.) which have  
been taken into the air conditioner.  
Mist or steam are  
emitted:  
G During Cooling or Dry operation, a thin mist may be seen emitted  
from the indoor unit. This results from the sudden Cooling of  
room air by the air emitted from the air conditioner, resulting in  
condensation and misting.  
*G During Heating operation, the outdoor units fan may stop, and  
steam may be seen rising from the unit. This is due to the Auto-  
matic Defrosting operation.  
15  
Airflow is weak or stops:  
*G When Heating operation is started, fan speed is temporarily very  
low, to allow internal parts to warm up.  
*G During Heating operation, if the room temperature rises above  
the thermostat setting, the outdoor unit will stop, and the indoor  
unit will operate at very low fan speed. If you wish to warm the  
room further, set the thermostat to a higher setting.  
*G During Heating operation, the unit will temporarily stop opera-  
tion (between 7 and 15 minutes) as the Automatic Defrosting mode  
operates. During the Automatic Defrosting operation, the OPERA-  
TION indicator lamp will flash.

G The fan may operate at very low speed during Dry operation or  
when the unit is monitoring the rooms temperature.

G In the monitor AUTO operation, the fan will operate at very low  
speed.  
Water is produced from  
the outdoor unit:  
*G During Heating operation, water may be produced from the out-  
15  
door unit due to the Automatic Defrosting operation.

OPERATING TIPS  
Operation and Performance  
*Heating Performance  
*Microcomputer-controlled Automatic Defrosting  
G This air conditioner operates on the heat-pump principle,  
absorbing heat from outdoor air and transferring that heat  
indoors. As a result, the operating performance is reduced  
as outdoor air temperature drops. If you feel that insuffi-  
cient heating performance is being produced, we recom-  
mend you use this air conditioner in conjunction with  
another kind of heating appliance.  
When using the Heating mode under conditions of low out-  
door air temperature high humidity, frost may form on the  
outdoor unit, resulting in reduced operating performance.  
In order to prevent this kind of reduced performance, this  
unit is equipped with a Microcomputer-controlled Automatic  
Defrosting function. If frost forms, the air conditioner will  
temporarily stop, and the defrosting circuit will operate  
briefly (for about 7 to 15 minutes).  
G Heat-pump air conditioners heat your entire room by  
recirculating air throughout the room, with the result that  
some time may be required after first starting the air con-  
ditioner until the room is heated.  
During Automatic Defrosting operation, the OPERATION  
indicator lamp (red) will flash.  
*When Indoor and Outdoor Temperatures are High  
*Low Ambient Cooling  
When both indoor and outdoor temperatures are high dur-  
ing use of the heating mode, the outdoor units fan may stop  
at times.  
When the outdoor temperature drops, the outdoor units fans  
may switch to Low Speed.

AUTO Restart  
In Event of Power Interruption  
G Should the power supply to the air conditioner be inter-  
rupted by a power failure, the air conditioner will restart  
automatically in the previously selected mode once the  
power is restored.  
G Use of other electrical appliances (electric shaver, etc.) or  
nearby use of a wireless radio transmitter may cause the  
air conditioner to malfunction. In this event, temporarily  
disconnect the power supply, reconnect it, and then use  
the remote control unit to resume operation.  
G Should a power failure occur during TIMER operation,  
the timer will be reset and the unit will begin (or stop)  
operating under the new timer setting. In this event, the  
TIMER indicator lamp (yellow) will flash (see page 4).
