SAFETY PRECAUTIONS
DANGER!
CAUTION!
●Do not attempt to install this air conditioner by yourself.
●This air conditioner contains no user-serviceable parts. Always consult authorized service personnel for repairs.
●When moving, consult authorized service personnel for disconnection and installation of the air conditioner.
●Do not become excessively chilled by staying for many hours in the direct cooling airflow.
●Do not insert fingers or objects into the outlet port or intake grille.
●Do not start and stop air conditioner operation by disconnecting the power supply cord and so on.
●Take care not to damage the power supply cord.
●In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the breaker, and consult authorized service personnel.
●If the power supply cord of this appliance is damaged, it should only be replaced by the authorized service personal, since special purpose tools and specified cord are required.
●Provide occasional ventilation during use.
●Do not direct airflow at fireplaces or heating apparatus.
●Do not climb on, or place objects on, the air conditioner.
●Do not hang objects from the indoor unit.
●Do not set flower vases or water containers on top of air conditioners.
●Do not expose the air conditioner directly to water.
●Do not operate the air conditioner with wet hands.
●Do not pull power supply cord.
●Turn off power supply when not using the indoor unit for extended periods.
●Check the condition of the installation stand for damage.
●Do not place animals or plants in the direct path of the airflow.
●Do not drink the water drained from the air conditioner.
●Do not use in applications involving the storage of foods, plants or animals, precision equipment, or art works.
●Connection valves become hot during Heating; handle with care.
●Do not apply any heavy pressure to radiator fins.
●Operate only with air filters installed.
●Do not block or cover the intake grille and outlet port.
●Ensure that any electronic equipment is at least one meter away from either the indoor or outdoor units.
●Avoid installing the air conditioner near a fireplace or other heating apparatus.
●When installing the indoor and outdoor unit, take precautions to prevent access to infants.
●Do not use inflammable gases near the air conditioner.

FEATURES AND FUNCTIONS
INVERTER
At the start of operation, a large power is used to bring the room quickly to the desired temperature. Afterward, the air conditioner 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 Control Unit 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.
MINIMUM HEAT OPERATION
The room temperature can be maintained at 50 °F so as to prevent the room temperature from falling too far.
SWING OPERATION
The Air Flow Direction Louvers swings automatically up and down so that the air speeds to every nook and corner of your room.
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 indoor unit begins super-quiet operation; the indoor unit’s airflow is reduced to produce quieter operation.
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 indoor unit’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 indoor unit automatically turns off.
WIRELESS REMOTE CONTROL UNIT
The Wireless Remote Control Unit allows convenient control of indoor unit operation.
WIRED REMOTE CONTROL UNIT (OPTION)
The optional wired remote control unit (model No.: UTY-RNBLU) can be used.
It requires the Communication Box Kit (Model Name: UTY-XCBXZ1) to connect the wired remote control.
When you use remote control unit, there are following different points as compared with using wireless remote control unit.
[The additional functions for wired ones]
•Weekly timer
•Temperature set back timer
[The restricted functions for wired ones]
•Horizontal Airflow Direction and swing
•MAINTENANCE
And you can use both wired and wireless remote control unit simultaneously. (But function is limited.)
[The restricted function for wireless ones]
•SLEEP
•TIMER
•COIL DRY
