FEATURES AND FUNCTIONS  
Energy saving and Comfortable function  
INVERTER  
SLEEP TIMER  
At the start of operation, large amount of 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.  
When the SLEEP button is pressed during Heating mode, the  
indoor unit’s temperature setting is gradually lowered during the  
period of operation; during cooling mode, the temperature set-  
ting is gradually raised during the period of operation. When the  
set time is reached, the indoor unit automatically turns off.  
ENERGY SAVING PROGRAM  
POWERFUL OPERATION  
When the sensor detects that there is no one in the room, it  
automatically reduces the operating power. It saves you mon-  
ey by reducing the power consumed.  
The product will operate at maximum power, which is convenient  
when you want to quickly cool down or warm up the room.  
ECONOMY OPERATION  
Clean function  
When ECONOMY operation mode is operated, the room tem-  
perature 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.  
MILDEW-RESISTANT FILTER  
The Air Filter has been treated to resist mildew growth, thus al-  
lowing cleaner use and easier care.  
SWING OPERATION  
POLYPHENOL CATECHIN AIR CLEANING FILTER  
The Airflow Direction Louvers swings automatically up and  
down so that the air speeds to every nook and corner of your  
room.  
The Polyphenol Catechin Air Cleaning lter uses static electricity  
to clean ne particles and dust in the air such as tobacco smoke  
and plant pollen that are too small to see. The lter contains cat-  
echin, which is highly effective against various bacteria by sup-  
pressing the growth of the bacteria adsorbed to the lter.  
Note that when the Air Cleaning Filter is installed, the amount of  
air produced decreases, causing a slight decrease in the indoor  
unit’s performance.  
AUTO CHANGEOVER  
The operation mode (cooling, dry, heating) is switched auto-  
matically to maintain the set temperature, and the temperature  
is kept constant at all times.  
SUPER QUIET OPERATION  
NEGATIVE AIR IONS DEODORIZING FILTER  
The indoor unit’s airow is reduced to produce quieter operation.  
MIN. (Minimum) HEAT OPERATION  
It comprises pottery super micro particles which can produce  
negative air ions having the effect of deodorizing and can absorb  
and remit the peculiar smell at home.  
The room temperature can be maintained at 50 °F so as to  
prevent the room temperature from falling too far.  
Remote controller  
OUTDOOR UNIT LOW NOISE OPERATION  
WIRELESS REMOTE CONTROLLER  
OUTDOOR UNIT LOW NOISE operation mode reduces the  
noise level of the outdoor unit by suppressing the fan speed  
and the rotation number of the compressor. It is effective when  
the surrounding area is quiet, such as in the night.  
The Wireless Remote Controller allows convenient control of in-  
door unit operation.  
WIRED REMOTE CONTROLLER (OPTION)  
Convenient function  
The optional wired remote controller can be used. When you  
use remote controller, there are following different points as  
compared with using wireless remote controller.  
WEEKLY TIMER  
And you can use both wired and wireless remote controller si-  
multaneously. (But function is limited)  
When the restricted functions on the remote controller are used,  
beeping sound will be heard, OPERATION, TIMER and the 3rd  
lamp of the indoor unit will ash.  
The combination of the temperature setting and the timer func-  
tion, which you can choose any day between Monday and  
Sunday, can be set freely.  
You can set up to four ON Timers or OFF Timers in one day.

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  
NORMAL  
FUNCTION  
Doesn’t operate  
immediately:  
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.  
Whenever the electrical breaker is turned off then on again the pro-  
tection circuit will operate for about 3 minutes, preventing unit opera-  
tion during that period.  
Noise is heard:  
During operation or immediately after stopping the unit, the sound of  
water owing 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 owing).  
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 occasional.  
This sound is produced by the Automatic Defrosting operation.  
23  
Smells:  
Some smell may be emitted from the indoor unit. This smell is the re-  
sult 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 emitted  
from the indoor unit. This results from the sudden Cooling of room air  
by the cool air emitted from the indoor unit, resulting 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 Automatic Defrosting  
operation.  
23  
Airow 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  
temperature 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 temperature for a higher setting.  
During Heating operation, the indoor unit will temporarily stop opera-  
tion (Max.15 minutes) as the Automatic Defrosting mode operates.  
During Automatic Defrosting operation, the OPERATION Indicator  
Lamp will ash.

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.

OPERATING TIPS  
Operation and Performance  
Microcomputer-controlled Automatic Defrosting  
Heating Performance  
When using the Heating mode under conditions of low out-  
door temperature and high humidity, frost may form on the  
outdoor unit, resulting in reduced operating performance.  
This air conditioner operates on the heat-pump principle,  
absorbing heat from outdoor air and transferring that heat  
to indoor unit. As a result, the operating performance 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.  
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 con-  
ditioner will temporarily stop, and the defrosting circuit will  
operate briey (Max. 15 minutes).  
Heat-pump air conditioners heat your entire room by recir-  
culating air throughout the room, with the result that some  
time may be required after rst starting the air conditioner  
until the room is heated.  
During Automatic Defrosting operation, the OPERATION  
Indicator Lamp (green) will ash.  
After heating operation stops, if frost forms on the outdoor  
unit, the unit will start Automatic Defrosting operation. At  
this time, the outdoor unit will automatically stop after oper-  
ating for a few minutes.  
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 auto-  
matically in its previous mode when the power is restored.  
If a power interruption occurs during TIMER operation, the tim-  
er 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 ash (see page 4.).  
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 turn off  
the circuit breaker, turn it on and then use the Remote Con-  
troller to resume operation.
