FEATURES AND FUNCTIONS
INVERTER
SWING OPERATION
At the start of operation, a large power is used to bring the
room quickly to the desired temperature. Afterwards, the
unit automatically switches to a low power setting for eco-
nomic and comfortable operation.
TheAir Flow Direction Louvers swings automatically up and
down so that the air speeds to every nook and corner of
your room.
REMOVABLE OPEN PANEL
COIL DRY OPERATION
The indoor unit’s Open Panel can be removed for easy clean-
ing and maintenance.
The Indoor unit can be dried by pressing the COIL DRY but-
ton on the Remote Control Unit so as to avoid going moldy
and restrain the breed of bacterium.
MILDEW-RESISTANT FILTER
AUTO CHANGEOVER
The AIR FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
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.
SUPER QUIET OPERATION
When the FAN CONTROL button is used to select QUIET, the
unit begins super-quiet operation; the indoor unit’s airflow
is reduced to produce quieter operation.
PROGRAM TIMER
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.
AIR CLEANING MODE
Relies on the air conditioner’s power to quickly purify the air
in the room.
SLEEP TIMER
When the SLEEP button is pressed during Heating mode,
the air conditioner’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 unit automati-
cally turns off.
ELECTRONIC AIR CLEAN FILTER
Install for use inside of the dust collection unit. For details
on how to install the filter, please refer to page 15.
Electrical power is used to charge the filter to remove con-
taminants from the air and to effectively collect dust and
remove odors. It also helps to reduce the bacterial activity.
WIRELESS REMOTE CONTROL UNIT
The Wireless Remote Control Unit allows convenient con-
trol of air conditioner operation.
WIRED REMOTE CONTROL UNIT (OPTION)
The optional wired remote control unit (model No.: UTB-UUB) can be used.
When you use remote control unit, there are following different points as compared with using wireless remote control unit.
[The additional functions for wired ones]
• Weekly timer
•Temperature set back timer
[The restricted functions for wired ones]
• Air-cleaning function can't be turned ON/OFF. (During operation, it is always ON)
• QUIET can't be selected in FAN MODE.
• Sleep-timer can't be used.
And you can't use both wired remote control unit and wireless simultaneously.

Doesn’t 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 Power Supply Plug is disconnected and then re-
connected to a power outlet, the protection 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 conditioner’s 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 occasional.
This sound is produced by the Automatic Defrosting operation.

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 unit’s fan may stop, and
steam may be seen rising from the unit. This is due to Automatic
Defrosting operation.

OPERATING TIPS
Operation and Performance
Microcomputer-controlled Automatic Defrosting
Heating Performance
G 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
unit is equipped with a Microcomputer-controlled Auto-
matic Defrosting function. If frost forms, the air condi-
tioner will temporarily stop, and the defrosting circuit will
operate briefly (for about 7-15 minutes).
G This air conditioner operates on the heat-pump princi-
ple, 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
insufficient heating performance is being produced, we
recommend you use this air conditioner in conjunction
with another kind of heating appliance.
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.
AUTO Restart
In Event of Power Interruption
G
If a power failure occurs during TIMER operation, the timer
will be reset and the 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).
G The air conditioner power has been interrupted by a
power failure. The air conditioner will then restart auto-
matically in its previous mode when the power is restored.
G Operated by setting before the power failure.
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 Plug, reconnect it, and then
use the Remote Control Unit to resume operation.

G If the air conditioner is used under higher temperature conditioner than those listed, the built-in protection circuit may
operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is used under conditions of
lower temperature than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
G Do not use this unit for any purposes other than the Cooling, Dehumidifying, and air-circulation of rooms in ordinary
dwellings.
G If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)
Tips for saving energy
G When the outdoor temperature is low (about 50 °F or less), the unit will consume the power of 20~40W unless the power
plug is disconnected from the outlet even if the air conditioner turns off.
G Remove the power plug to stop the power supply for energy saving when not using for a long time.
