FEATURES AND FUNCTIONSFEATURES 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.

ECONOMY OPERATION

Limits the maximum operation current, and performs operation with the power consumption suppressed. When economy operation mode is operated, the room temperature will be little higher than the set-temp under cooling mode and lower than set-temp under heating mode. Therefore, the economy mode is able to save more energy than other normal mode.

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.

MINIMUM HEAT OPERATION

The room temperature can be maintained at 50°F so as to prevent the room temperature from falling too far.

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.

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.

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 INTAKE GRILLE

The indoor unit’s INTAKE GRILLE 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 button is used to select QUIET, the unit begins super-quiet operation; the indoor unit’s airflow is reduced to produce quieter operation.

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.

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)

TROUBLESHOOTING

WARNING!

Before requesting service, perform the following checks:

NORMAL

FUNCTION

Doesn’t operate immediately:

Noise is heard:

Smells:

Mist or steam are emitted:

Airﬂ ow is weak or stops:

Water is produced from the outdoor unit:

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 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.

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.

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

●

(Max. 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 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 recir-

●

culating 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.

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.

●

Microcomputer-controlled Automatic Defrosting

When using the Heating mode under conditions of low out-

●

door 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 briefly (Max. 15 minutes).

During Automatic Defrosting operation, the OPERATION

Indicator Lamp will ﬂ ash.

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.

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 turn off the circuit breaker, turn it on and then use the Remote Controller to resume operation.
