FEATURES AND FUNCTIONS  
INVERTER  
MILDEW-RESISTANT FILTER  
The AIR FILTER has been treated to resist mildew growth,  
thus allowing cleaner use and easier care.  
At the start of operation, a large power is used to bring the  
room quickly to the desired temperature. Afterward, the  
air conditioner automatically switches to a low power set-  
ting for economic and comfortable operation.  
SUPER QUIET OPERATION  
When the FAN button is used to select QUIET, the indoor  
unit begins super-quiet operation; the indoor unit’s airflow  
is reduced to produce quieter operation.  
WIRELESS REMOTE CONTROLLER  
The Wireless Remote Controller allows convenient control  
of indoor unit operation.  
POLYPHENOL CATECHIN AIR CLEANING FILTER  
ECONOMY OPERATION  
The polyphenol catechin air cleaning filter uses static  
electricity to clean fine particles and dust in the air such  
as tobacco smoke and plant pollen that are too small to  
see. The filter contains catechin, which is highly effective  
against various bacteria by suppressing the growth of the  
bacteria adsorbed to the filter.  
When ECONOMY operation mode is operated, the room  
temperature will be little higher than the set-temp under  
cooling mode and lower than set-temp under heating  
mode. Therefore, the ECONOMY mode is able to save  
more energy than other normal mode.  
Note that when the air cleaning filter is installed, the  
amount of air produced decreases, causing a slight de-  
crease in the indoor unit’s performance.  
AUTO CHANGEOVER  
The operation mode (cooling, dry, heating) is switched au-  
tomatically to maintain the set temperature, and the tem-  
perature is kept constant at all times.  
NEGATIVE AIR IONS DEODORIZING FILTER  
It comprises pottery super micro particles which can pro-  
duce negative air ions having the effect of deodorizing and  
can absorb and remit the peculiar smell at home.  
MINIMUM HEAT OPERATION  
The room temperature can be maintained at 50 °F so as to  
prevent the room temperature from falling too far.  
PROGRAMTIMER  
The program timer allows you to integrate OFF timer and  
ON timer operations in a single sequence. The sequence  
can involve one transition from OFF timer to ON timer, or  
from ON timer to OFF timer, within a twenty-four hour pe-  
riod.  
SLEEPTIMER  
When the SLEEP button is pressed during Heating mode,  
the indoor unit’s thermostat setting is gradually lowered  
during the period of operation; during cooling mode, the  
thermostat setting is gradually raised during the period of  
operation. When the set time is reached, the indoor unit  
automatically turns off.  
SWING OPERATION  
The Air Flow Direction Louvers swings automatically up  
and down so that the air speeds to every nook and corner  
of your room.  
REMOVABLE INTAKE GRILLE  
The indoor unit’s Intake Grille can be removed for easy  
cleaning and maintenance.

About AUTO CHANGEOVER Operation  
AUTO:  
When AUTO CHANGEOVER operation first selected, the fan will op-  
erate at very low speed for about a few minutes, during which time  
the indoor unit detects the room conditions and selects the proper  
operation mode.  
If the difference between thermostat setting and actual room tem-  
perature is more than +4 °F Cooling or dry operation  
If the difference between thermostat setting and actual room tem-  
perature is within 4 °F Determined by outdoor temperature  
If the difference between thermostat setting and actual room tem-  
perature is more than –4 °F Heating operation  
When the indoor unit has adjusted your room’s temperature to near  
the thermostat setting, it will begin monitor operation. In the monitor  
operation mode, the fan will operate at low speed. If the room tem-  
perature subsequently changes, the indoor unit will once again select  
the appropriate operation (Heating, Cooling) to adjust the tempera-  
ture to the value set in the thermostat.

in a single sequence. The sequence can involve one transition from OFF timer  
to ON timer, or from ON timer to OFF timer, within a twenty-four hour period.  
The first timer function to operate will be the one set nearest to the current  
time. The order of operation is indicated by the arrow in the Remote Control-  
ler's Display (OFF ON, or OFF ON).  
One example of Program timer use might be to have the air conditioner auto-  
matically stop (OFF timer) the operation after you go to sleep, then start (ON  
timer) the operation automatically in the morning before you arise.

About the SLEEPTimer  
To prevent excessive warming or cooling during sleep, the SLEEP timer function automatically modifies the thermostat set-  
ting in accordance with the set time setting. When the set time has elapsed, the air conditioner completely stops.  
During Heating operation:  
During Cooling/Dry operation:  
When the SLEEP timer is set, the thermostat setting is  
automatically lowered 2 °F every thirty minutes. When the  
thermostat setting is lowered a total of 8 °F, the thermostat  
setting at that time is maintained until the set time elapses,  
at which time the air conditioner automatically turns off.  
When the SLEEP timer is set, the thermostat setting is auto-  
matically raised 2 °F every sixty minutes. When the thermo-  
stat setting is raised a total of 4 °F, the thermostat setting at  
that time is maintained until the set time elapses, at which  
time the air conditioner automatically turns off.

At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation for cooling and  
heating.  
If the room is not cooled (or heated) well during ECONOMY operation, select normal operation.  
During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation  
even if ECONOMY operation is selected by pressing the ECONOMY operation button.  
When ECONOMY operation mode is operated, the room temperature will be little higher than the set-temp under cool-  
ing mode and lower than set-temp under heating mode. Therefore, the ECONOMY mode is able to save more energy  
than other normal mode.  
In case of multi-type air conditioner, the ECONOMY operation mode is only available for the set indoor unit.

TROUBLESHOOTING  
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the  
electrical breaker and consult authorized service personnel.  
WARNING!  
Merely turning off the unit’s power switch will not completely disconnect the unit from the power  
source. Always be sure to turn off the electrical breaker to ensure that power is completely off.  
Before requesting service, perform the following checks:  
Symptom  
Problem  
See Page  
Doesn’t operate immedi-  
ately:  
If the indoor unit is stopped and then immediately started  
again, the compressor will not operate for about 3 minutes, in  
order to prevent fuse blowouts.  
NORMAL  
FUNCTION  
Whenever the electrical breaker is turned off then on again the  
protection circuit will operate for about 3 minutes, preventing  
unit operation during that period.  
During operation or immediately after stopping the unit, the  
sound of water flowing in the air conditioner’s piping may be  
heard. Also, noise may be particularly noticeable for about 2 to  
3 minutes after starting operation (sound of refrigerant flowing).  
Noise is heard:  
During operation, a slight squeaking sound may be heard. This  
is the result of minute expansion and contraction of the front  
panel due to temperature changes.  
During Heating operation, a sizzling sound may be heard occasion-  
al. This sound is produced by the Automatic Defrosting operation.  
16  
Smells:  
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 indoor unit.  
Mist or steam is  
emitted:  
During Cooling or Dry operation, a thin mist may be seen emit-  
ted from the indoor unit. This results from the sudden Cooling  
of room air by the cool air emitted from the indoor unit, result-  
ing in condensation and misting.  
During Heating operation, the outdoor unit’s fan may stop, and  
steam may be seen rising from the unit. This is due to Automat-  
ic Defrosting operation.  
16  
Airflow is weak or stops:  
When Heating operation is started, fan speed is temporarily  
very low, to allow internal parts to warm up.  
During Heating operation, if the room temperature rises above  
the thermostat setting, the outdoor unit will stop, and the in-  
door unit will operate at very low fan speed. If you wish to  
warm the room further, set the thermostat for a higher setting.  
During Heating operation, the indoor unit will temporarily stop  
operation (between 7 and 15 minutes) as the Automatic Defrost-  
ing mode operates. During Automatic Defrosting operation, the  
OPERATION Indicator Lamp will flash.  
16  
7
During Dry mode, the indoor unit will operate at low speed; in  
order to adjust room humidity, the indoor unit’s fan may stop  
from time to time. Also, the fan may operate at very low speed  
when adjusting room humidity.

During SUPER QUIET operation, the fan will operate at very low speed.  
In the monitor of AUTO operation, the fan will operate at very  
low speed.  
In case of Multi-type unit, if multiple units are operated in different  
operation modes as shown below, the units operated afterward  
will stop and the OPERATION indicator lamp (green) will flash.

OPERATINGTIPS  
Operation and Performance  
Microcomputer-controlled Automatic Defrosting  
Heating Performance  
When using the Heating mode under conditions of low  
outdoor temperature and high humidity, frost may form  
on the outdoor unit, resulting in reduced operating per-  
formance.  
In order to prevent this kind of reduced performance,  
this air conditioner is equipped with a Microcomputer-  
controlled Automatic Defrosting function. If frost forms,  
the air conditioner will temporarily stop, and the de-  
frosting circuit will operate briefly (for about 7-15 min-  
utes).  
This air conditioner operates on the heat-pump princi-  
ple, absorbing heat from outdoor air and transferring  
that heat to indoor unit. As a result, the operating per-  
formance is reduced as outdoor air temperature drops.  
If you feel that insufficient heating performance is being  
produced, we recommend you use this air conditioner  
in conjunction with another kind of heating appliance.  
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 conditioner until the room is heated.  
During Automatic Defrosting operation, the OPERATION  
Indicator Lamp (green) will flash.  
After heating operation stops, if frost forms on the out-  
door unit, the unit will start Automatic Defrosting op-  
eration. At this time, the outdoor unit will automatically  
stop after operating for a few minutes.

OPERATINGTIPS  
AUTO Restart  
In Event of Power Interruption  
The power supply to the air conditioner is stopped by a  
power interruption. The air conditioner will then restart  
automatically in its previous mode when the power is  
restored.  
If a power interruption occurs during TIMER operation, the  
timer will be reset and the indoor unit will begin (or stop)  
operation at the new time setting. In the event that this  
kind of timer fault occurs, the TIMER Indicator Lamp will  
flash (see Page. 3).  
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, tempo-  
rarily turn off the circuit breaker, turn it on and then use  
the Remote Controller to resume operation.  
Multi-type Air conditioner  
This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units  
to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective  
output.  
Simultaneous Use of Multiple Units  
When using a multi-type air conditioner, the multi-  
ple indoor units can be operated simultaneously, but  
when two or more indoor units of the same group are  
operated simultaneously, the heating and cooling ef-  
ficiency will be less than when a single indoor unit is  
used alone. Accordingly, when you wish to use more  
than one indoor unit for cooling at the same time, the  
use should be concentrated at night and other times  
when less output is required. In the same way, when  
multiple units are used simultaneously for heating, it  
is recommended that they be used in conjunction with  
other auxiliary space heaters, as required.  
Operation can be done in the following different oper-  
ating modes.  
Cooling mode and dry mode  
Cooling mode and fan mode  
Dry mode and fan mode  
The operating mode (heating mode or cooling (dry)  
mode) of the outdoor unit will be determined by the  
operating mode of the indoor unit that was operated  
first. If the indoor unit was started in fan mode, the  
operating mode of the outdoor unit will not be deter-  
mined.  
Seasonal and outdoor temperature conditions, the  
structure of the rooms and the number of persons  
present may also result in differences of operating ef-  
ficiency. We recommend that you try various operat-  
ing patterns in order to confirm the level of heating  
and cooling output provided by your units, and use  
the units in the way that best matches your family’s  
lifestyle.  
For example, if indoor unit (A) was started in fan mode  
and then indoor unit (B) was then operated in heating  
mode, indoor unit (A) would temporarily start opera-  
tion in fan mode but when indoor unit (B) started  
operating in heating mode, the OPERATION indicator  
lamp (green) for indoor unit (A) would begin to flash (1  
second on, 1 second off) and it would go into standby  
mode. Indoor unit (B) would continue to operate in  
heating mode.  
If you discover that one or more units delivers a low  
level of cooling or heating during simultaneous opera-  
tion, we recommend that you stop simultaneous op-  
eration of the multiple units.  
Operation cannot be done in the following different  
operating modes.  
If the indoor unit is instructed to do an operating mode  
that it cannot perform, the OPERATION indicator lamp  
(green) on the indoor unit will flash (1 second on, 1  
second off) and the unit will go into the standby mode.  
Heating mode and cooling mode (or dry mode)  
Heating mode and fan mode  
Notice  
During use of the heating mode, the outdoor unit will  
occasionally commence the defrost operation for brief  
periods. During the defrosting operation, if the user  
sets the indoor unit for heating again, the defrosting  
mode will continue, and the heating operation will be-  
gin after completion of defrosting, with the result that  
some time may be required before warm air is emitted.  
During use of the heating mode, the top of the indoor  
unit may become warm, but this is due to the fact  
that coolant is circulated through the indoor unit even  
when it is stopped; it is not a malfunction.
