FEATURES AND FUNCTIONS

INVERTER
At the start of the operation, a large power is used to bring the room quickly to the desired temperature. Afterward, 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 the bacterium.

AUTO CHANGEOVER
The operation mode (cooling, drying, 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 the Heating mode, the air conditioner’s thermostat setting is gradually lowered during the period of operation; during the 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 the air conditioner operation.

HORIZONTAL AIRFLOW: COOLING/ DOWNWARD AIRFLOW: HEATIN G
For cooling, use horizontal airflow so the cool air does not blow directly on the occupants in the room. For heating, use downward airflow ow to send powerful, warm air to the floor and create a comfortable environment.

WIRED REMOTE CONTROLLER (OPTION)

The optional wired remote controller (model No. : UTB-YUD) can be used. When you use a remote controller, there are following different points as compared with using a wireless remote controller.
[The additional functions for wired remote controller]

• Weekly timer
• Temperature setback 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. (Only one kind can be selected)

OMNI-DIRECTIONAL AIR FLOW
(SWING OPERATION)
Three-dimensional control over air direction swing is possible through the dual use of both a UP/DOWN air direction swing and a 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.

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 airflow is reduced to produce quieter operations.

POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning filter uses static electricity to clean the air of fine particles and dust such as tobacco smoke and plant pollen that are too small to see. The filter contains catechin, which is highly effective against various bacteria by suppressing the growth of the bacteria adsorbed by the filter. Note that when the air cleaning filter is installed, the amount of air produced decreases, causing a slight decrease in the air conditioner’s performance.

NEGATIVE AIR IONS DEODORIZING FILTER
It comprises pottery super microparticles, which can produce negative air ions having the effect of deodorizing and can absorb  and remit the peculiar smell at home

TROUBLESHOOTING

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 the power is completely off. Before requesting service, perform the following checks: the problem persists after performing these checks, or if you notice burning smells, or both the OPERATION Indicator Lamp (Fig. 3 and the TIMER Indicator Lamp (Fig. 3 6) fl ashes, or only the TIMER Indicator Lamp (Fig. 3 6) fl ashes, immediately stop operation, disconnect the Power Supply, and consult authorized service personnel

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.

|

—

●  During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation.|

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 insufficient
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 first starting the air conditioner until the room is heated

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 briefly (for about 7-15 minutes). During Automatic Defrosting operation, the OPERATION Indicator Lamp (red) will fl ash

AUTO Restart
In the Event of Power Interruptio n
The air conditioner’s 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 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.

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| About 30 °C or less

• If the air conditioner is used under a 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 floor 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 the device, the outdoor unit may stop operation for a certain period of time.
