CLEANING AND CARE  
÷ Dust can be cleaned from the Air Filter either with a  
vacuum cleaner, or by washing the filter in a solution of  
mild detergent and warm water. If you wash the filter,  
be sure to allow it to dry thoroughly in a shady place  
before reinstalling.  
÷ If dirt is allowed to accumulate on the Air Filter, air flow  
will be reduced, lowering operating efficiency and  
increasing noise.  
Cleaning the Air Filter  
1. Open the Intake Grille, and remove the Air  
Filter.  
Lift up the air filter's handle, disconnect the two lower  
tabs and pull out.  
Air filter handle  
÷ During periods of normal use, the Air Filters should be  
cleaned every two weeks.  
Hooks (two places)  
2. Remove dust with a vacuum cleaner or  
by washing.  
After washing, allow to dry thoroughly in a shaded  
place.  
3. Replace the Air Filter and close the Intake  
Grille.  
1 Align the sides of the Air Filter with the panel, and  
push in fully, making sure the two lower tabs are  
returned properly to their holes in the panel.  
Hooks (two places)  
2 Close the Intake Grille.  
(For purposes of example, the illustration shows the  
unit without Intake Grille installed.)  
When using the optional Air Cleaning Filter  
÷ Install the optional Air Cleaning Filter set (UTR-FA03) as instructed (Instruction Manual are furnished with the Air Cleaning  
Filter set).  
÷ When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that  
the unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized  
service personnel.  
÷ When cleaning the unit's body, do not use water hotter than 40°C, harsh abrasive cleansers, or volatile agents like  
benzene or thinner.  
÷ Do not expose the unit body to liquid insecticides or hairsprays.  
÷ When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about  
onehalf day to allow internal parts to dry thoroughly.

TROUBLE SHOOTING  
In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect  
the Power and consult authorized service personnel.  
WARNING!  
Merely turning off the unit’s power switch will not completely disconnect the unit from the  
power source. Always be sure to disconnect the Power or turn off your circuit breaker to  
ensure that power is completely off.  
Before requesting service, perform the following checks:  
Symptom  
Problem  
See Page  
NORMAL  
FUNCTIONS  
Doesn’t 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 Power is disconnected and then reconnected to  
a power outlet, 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 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.  
––––  
––––  
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.  
––––  
Airflow is weak or stops:  
÷ The fan may operate at very low speed during Dry operation  
or when the unit is monitoring the room’s temperature.

Poor Cooling performance:  
÷ Is the air filter 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?  
÷ Is a window allowing bright sunlight to enter? (Close the curtains.)  
÷ 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?

The unit operates  
differently from the  
remote control unit's  
setting:  
÷ Are the Remote Control Unit's batteries dead?  
÷ Are the Remote Control Unit's batteries loaded properly?  
If the problem persists after performing these checks, or if you notice burning smells, or the  
TIMER Indicator Lamp (Fig. 3, 6) flashes, immediately stop operation, disconnect the Power  
and consult authorized service personnel.  
WARNING!  
OPERATING TIPS  
Operation and Performance  
In Event of Power Interruption  
÷ 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  
(green) will flash (see page 5).  
÷ 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, reconnect it, and then  
use the Remote Control Unit to resume operation.  
Auto Restart  
÷ 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 settings before the power failure. Then, the  
Air Flow Direction Louvers will automatically change to  
their standard direction.
