FEATURES AND FUNCTIONS
INVERTER
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.
COIL DRY OPERATION
The Indoor unit can be dried by pressing the COIL DRY button
on the Remote Controller so as to avoid going moldy and restrain
the breed of bacterium.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) 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 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 automatically turns off.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of air
conditioner operation.
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.
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.
NEGATIVE AIR IONS DEODORIZING FILTER
HORIZONTAL AIRFLOW: COOLING/
DOWNWARD AIRFLOW: HEATING
For cooling, use horizontal airfl ow so the cool air does not blow
directly on the occupants in the room. For heating, use downward airfl ow to send powerful, warm air to the fl oor and create
a comfortable environment.
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. : UTB-YUD) 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 remote controller]
● Weekly timer ● Temperature set back timer
[The restricted functions for wired remote controller]
● ECONOMY ● MAINTENANCE ● THERMO SENSOR
And you can't use both wired remote controller and wireless remote controller simultaneously.

NORMAL
FUNCTION
Symptom Problem
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam are emitted:
● 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 reconnected
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.
●
During Heating operation, a sizzling sound may be heard occasional.
This sound is produced by the Automatic Defrosting operation.
● 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.
● 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.

Poor Cooling performance:
The unit operates
differently from the Remote
Controller’s setting:
● 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 indoor 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 unit will temporarily stop operation (between 7 and 15 minutes) as the Automatic Defrosting mode operates.
During Automatic Defrosting operation, the OPERATION Indicator
Lamp will fl ash.
● The fan may operate at very low speed during Dry operation or when
the unit is monitoring the room’s temperature.
●
During SUPER QUIET operation, the fan will operate at very low speed.
In the monitor AUTO operation, the fan will operate at very low speed.
●
● During Heating operation, water may be produced from the outdoor
unit due to Automatic Defrosting operation.
● Is the Power Supply Plug disconnected its outlet?
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
● Is the timer operating?
● Is the Air Filter dirty?
● Air the air conditioner’s intake grille or outlet port blocked?
● Did you adjust the room temperature settings (thermostat) correctly?
● Is there a window or door open?
● In the case of Cooling operation, is a window allowing bright sunlight
to enter? (Close the curtains.)
● In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room?
● Is the unit set for SUPER QUIET operation?
● Are the Remote Controller’s batteries dead?
● Are the Remote Controller’s batteries loaded properly?

OPERATING TIPS
Operation and Performance
Heating Performance
● This air conditioner operates on the heat-pump principle,
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 insuffi cient
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 fi rst starting the air conditioner until the
room is heated.
En-15
Microcomputer-controlled Automatic Defrosting
● 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 performance.
In order to prevent this kind of reduced performance, this unit is
equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily
stop, and the defrosting circuit will operate briefl y (for about
7-15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (red) will fl ash.
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.
● Operated by setting before the power failure.
Temperature and Humidity Range
Cooling Mode Dry Mode Heating Mode
Outdoor temperature About -10 to 46 °C About -10 to 46 °C About –15 to 24 °C
Indoor temperature About 18 to 32 °C About 18 to 32 °C
● 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.
● Do not use this unit for any purposes other than the Cooling, Dehumidifying, and air-circulation of rooms in ordinary dwellings.
● 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 fl oor or other objects underneath. (About 80% or more).
● If the outdoor temperature is lower than the temperature scope in the list above, in order to keep safety operation of device, the
outdoor unit may stop operation for certain period of time.
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 fl 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 disconnect the Power Supply Plug, reconnect it, and then use the
Remote Controller to resume operation.
