FEATURES AND FUNCTIONS
INVERTER
REMOVABLE OPEN PANEL
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 economic and
comfortable operation.
The indoor unit’s Open Panel can be removed for easy cleaning
and maintenance.
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) is switched automatically
to maintain the set temperature, and the temperature 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 period.
SLEEP TIMER
When the SLEEP button is pressed during cooling mode, the ther-
mostat setting is gradually raised during the period of operation.
When the set time is reached, the unit automatically turns off.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of air
conditioner operation.
HORIZONTAL AIRFLOW
For cooling, use horizontal airflow so the cool air does not blow
directly on the occupants in the room.
OMNI-DIRECTIONAL AIR FLOW
(SWING OPERATION)
Three-dimensional control over air direction swing is possible
through dual use of both an UP/DOWN air direction swing and
RIGHT/LEFT air direction swing. Since UP/DOWN air direction
flaps operate automatically according to the operating mode of
the unit, it is possible to set air direction based on the operating
mode.
WIRED REMOTE CONTROLLER (OPTION)
The optional wired remote controller (model No.: UTY-RNBLU)
can be used.
When you use remote controller, there are following different
points as compared with using wireless remote controller.
[The additional functions for wired ones]
• Weekly timer
• Temperature set back timer
[The restricted functions for wired ones]
• MAINTENANCE (FILTER RESET)
• THERMO SENSOR
And you cannot use both wired and wireless remote controller
simultaneously.
(Only one kind can be selected)

FUNCTION
Doesn’t operate immedi-
ately:
● 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.
—
●
Whenever the Power Supply Plug is disconnected and then recon-
nected to a power outlet, the protection circuit will operate for about
3 minutes, preventing unit operation during that period.
Noise is heard:
● 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).
—
● 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.
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 air conditioner.
—
—
Mist or steam are
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 air emitted from the air conditioner, resulting in condensation
and misting.
Airflow is weak or stops:
● The fan may operate at very low speed during Dry operation or when
the unit is monitoring the room’s temperature.

disconnect the Power Supply, and consult authorized service personnel.
OPERATING TIPS
AUTO Restart
In Event of Power Interruption
● The air conditioner power has been interrupted by a power
failure. The air conditioner will then restart automatically in
its previous mode when the power is restored.
●
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. 4).
● Operated by setting before the power failure.
● 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 discon-
nect the Power Supply Plug, reconnect it, and then use the
Remote Controller to resume operation.
