This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the appliance.
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.
AUTO CHANGEOVER
The operation mode (cooling, dry) is switched automatically
to maintain the set temperature, and the temperature is kept
constant at all times.
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
thermostat setting is gradually raised during the period of
operation. When the set time is reached, the unit automatically turns off.
REMOVABLE OPEN PANEL
The indoor unit’s Open Panel can be removed for easy cleaning and maintenance.
MILDEW-RESISTANT FILTER
The AIR FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
SUPER QUIET OPERATION
When the FAN CONTROL button is used to select QUIET, the
unit begins super-quiet operation; the indoor unit’s airfl ow
is reduced to produce quieter operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning fi lter uses static electricity to clean the air of fi ne particles and dust such as tobacco
smoke and plant pollen that are too small to see.
The fi lter contains catechin, which is highly effective against
various bacteria by suppressing the growth of the bacteria
adsorbed by the fi lter.
Note that when the air cleaning fi lter is installed, the amount
of air produced decreases, causing a slight decrease in the
air conditioner’s performance.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control
of air conditioner operation.
HORIZONTAL AIRFLOW
For cooling, use horizontal airfl ow 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 fl aps operate automatically according to the
operating mode of the unit, it is possible to set air direction
based on the operating mode.
NEGATIVE AIR IONS DEODORIZING FILTER
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.
WIRED REMOTE CONTROLLER (OPTION)
The optional wired remote controller (model No.: UTY-RNBYU)
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]
• MAIN TENANCE (FILTER RESET)
• THERMO SENSOR
And you can’t use both wired remote controller and wireless
simultaneously.

Before requesting service, perform the following checks:
NORMAL
FUNCTION
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker or disconnect the power supply plug, and consult authorized service personnel.
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 or disconnect the power supply plug to
ensure that power is completely off.
Symptom
● If the 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 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.
● During operation and immediately after stopping the unit, the
sound of water fl 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 coolant fl owing).
● 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.
● 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.
● 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.
