OPERATING TIPS
Instructions relating to heating (*) are applicable only to
Heating and Cooling model (Reverse Cycle).
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. Also, please consult with
your installation technician to ensure the unit is correctly
sized for the room space required.
• 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.
When indoor and outdoor temperatures are high*
When both indoor and outdoor temperatures are high during use
of the Heating mode, the outdoor unit’s fan may stop at times.
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, reducing the operating performance.
In order to prevent this reduced performance, this product
is equipped with a microcomputer-controlled automatic
defrosting function. During the defrost cycle, the indoor fan
will shut down, and the defrost mode will be indicated. It
will take maximum of 15 minutes before the air conditioner
starts up again.
• 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
operating for a few minutes.

Vertical air direction adjustment
Airfl ow direction setting:1, 2, 3, 4: During cooling/heating/dry mode
NOTES
• Attempting to move up/down air direction fl aps manu-
ally could result in improper operation; in this case, stop
operation and restart. The louvers should begin to operate
properly again.
• When used in a room with infants, children, elderly or sick
persons, the air direction and room temperature should be
considered carefully when making settings.

• Use for gently cooling while dehumidifying your room.
• You cannot heat the room during Dry mode.
• During Dry mode, the 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.
• The fan speed cannot be changed manually when Dry
mode has been selected.
Fan speed
Controls the fan speed.
AUTO HIGH QUIETMED LOW
When AUTO is selected, the fan speed is automatically adjusted according to the operation mode.
Heating*: The fan will operate at very low speed when the
temperature of the air issued from the indoor unit
is low.
Cooling: As the room temperature approaches that of the
set temperature, the fan speed becomes slower.
Fan: The fan runs at medium fan speed.
Auto restart
In Event of Power Interruption
• Should the power supply to the air conditioner be interrupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
• 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, reconnect it, and then use
the remote controller to resume operation.
If only the following remote controller is connected, auto
restart is not performed.
UTY-R*RY

Notices
• During use of the Heating mode, the outdoor unit will
*
occasionally commence the defrost operation for brief
periods. During the defrosting operation, if the user sets
the indoor unit for heating again, the defrosting mode
will continue, and the Heating operation will begin after
completion of defrosting, with the result that some time
may be required before warm air is emitted.
*
• During use of the Heating mode, the top of the indoor
unit may become warm, but this is due to the fact that
coolant is circulated through the indoor unit even when it
is stopped; it is not a malfunction.
TROUBLESHOOTING
Instructions relating to heating (*) are applicable only to
Heating and Cooling model (Reverse Cycle).
WARNING
In the following events, immediately stop operation of the air conditioner, and disconnect all the
power supply by turning off the electrical breaker
or disconnecting the power plug. Then consult your
dealer or authorized service personnel.
As long as the unit is connected to the power supply, it is not insulated from the power supply even if
the unit is turned off.
• Unit smells of something burning or emits smoke
• Water leaks from the unit.
Before requesting service, perform the following checks:
NORMAL FUNCTION
Does not operate immediately
• 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 electrical breaker is turned off then on
again, 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 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
occasionally. This sound is produced by the Automatic
defrosting operation.
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.
* • During Heating operation, the outdoor unit’s fan may
stop, and steam may be seen rising from the unit. This is
due to the Automatic defrosting operation.
Humidity does not drop
In the case of Dry operation.
• In some conditions of the room, the humidity does not
drop.
• In order to lower the humidity, set a lower room temperature.
Airfl ow is weak or stops
• Indoor unit fan may start later than the outdoor unit fan,
or it may stop when the outdoor unit fan is not operating.
This is due to the Indoor unit fan control for energy saving operation.
• To disable this function, refer to the operation manual of
the remote controller. (This function cannot be disabled
in Auto fan mode.)
* • When Heating operation is started, fan speed is tempo-
rarily 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 to
a higher setting.
* • During Heating operation, the unit will temporarily stop
operation (maximum of 15 minutes) as the Automatic
defrosting mode operates. During the Automatic defrosting operation, the defrost mode will be indicated.
<<See operating manual of Remote controller.>>
• The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.
• During Quiet operation, the fan will operate at very low
speed.
• In the monitor Auto operation, the fan will operate at very
low speed.
The fl ow direction does not change according to the
setting or does not change at all
• Even if the fl ow direction is set, it may operate temporar-
ily at a different position at the start of heating operation, during defrost, or when AUTO (auto changeover) is
selected.
Water is produced from the outdoor unit
* • During Heating operation, water may be produced from
the outdoor unit due to the Automatic defrosting operation.
En-5
CHECK ONCE MORE
Does not operate at all
• Has the circuit breaker been turned off?
• Has there been a power failure?
• Has a fuse blown out, or a circuit breaker been tripped?
• Is the timer operating?
Poor cooling (or heating*) performance
• Is the air fi lter dirty?
• Are 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 Quiet operation?
• Is the air conditioner in Economy mode?
If the problem persists after performing these checks, or
if you notice burning smells, stop operation immediately,
disconnect the power supply, and consult with authorized
service personnel.
