OPERATION

About Mode Operation

AUTO: ● Depending on the room temperature at the time operation begins, the

operating mode will be switched automatically as shown in the accompanying table. Also, depending on the operating mode, the room temperature setting will cause the “standard” temperature to be set as shown.

Actual Room Operating Mode Thermostat Setting Temperature (standard setting) 88 °F or above → Cooling → 82 °F 82 °F to 88 °F → Cooling → 80 °F 78 °F to 82 °F → Dry → 76 °F 74 °F to 78 °F → Dry → 72 °F Below 74 °F → Dry → 68 °F

The operating mode and standard thermostat settings are selected automatically when operation begins.

● When automatic operation is initiated, the fan will run at very low speed for about one minute while the unit detects and selects the proper operating mode.

● Once the operating mode has been set, the mode will not change even if the room temperature changes.

● If the START/STOP button is pressed to recommence operation within two hours after stopping automatic operation, the unit will begin operating from the same mode as before.

Cooling: ● Use to cool your room. Dry: ● 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: ● Use to circulate the air throughout your room.

During Cooling/Dry mode:

Set the thermostat to a temperature setting that is lower than the current room temperature. The Cooling and Dry modes will not operate if the thermostat is set higher than the actual room temperature (in Cooling mode, the fan alone will operate).

During Fan mode:

ADJUSTING THE DIRECTION OF AIR CIRCULATION

Vertical (up-down) direction of airflow is adjusted by pressing the Remote Control Unit’s SET button. Horizontal (right-left) airflow direction is adjusted manually, by moving the Air Flow Direction Louvers. Whenever making horizontal airflow adjustments, start air conditioner operation and be sure that the vertical air direction louvers are stopped.

Vertical Air Direction Adjustment

Press the SET button (Fig. 6 O).

Each time the button is pressed, the air direction range will change as follows:

2 3 4 5 6 7

Types of Air flow Direction Setting:

1,2,3 : During Cooling / Dry modes 1,2,3,4,5,6,7 : During Fan mode

The remote Control Unit’s display does not change.

● Use the air direction adjustments within the ranges shown above.

● The vertical airflow direction is set automatically as shown, in accordance with

the type of operation selected.

During Cooling / Dry / Fan mode : Horizontal flow 1

● During AUTO mode operation, for the first minute after beginning operation,

airflow will be horizontal 1; the air direction cannot be adjusted during this period.

Right-Left Adjustment

Adjust the Right-Left louvers.

● Move the Right-Left louvers to adjust air flow in the direction you prefer.

DANGER!

● Never place fingers or foreign objects inside the outlet ports, since the internal fan operates at high speed and could cause personal injury.

● Always use the remote control unit’s SET button to adjust the vertical airflow louvers. Attempting to move them manually could result in improper operation; in this case, stop operation and restart. The louvers should begin to operate properly again.

● During Cooling and Dry modes, do not move the vertical air direcion louvers outside their proper operating range for the mode (1 - 3) and into the fan region (4 - 7) ; using the louvers in the fan region will cause moisture to condense near the air outlet, and water may drop onto the floor. During the Cooling / Dry modes, if the louvers are operated outside the range 1 - 3 for more than 30 minutes, they will automatically return to position 3 range.

● 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.

DANGER!

● When adjusting the Right-Left Louvers, it is necessary to stop the Air-Conditioner first and make sure that it stops completely before adjusting the direction.

TROUBLESHOOTING

WARNING!

Before requesting service, perform the following checks:

NORMAL

FUNCTION

Doesn’t operate immediately:

Noise is heard:

Smells:

Mist is emitted:

Airflow is weak or stops:

In the event of a malfunction (burning smell, etc.), immediately stop operation, 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 disconnect the Power Supply Plug or turn off your circuit breaker to ensure that power is completely off.

Symptom

● 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 Supply Plug is disconnected and then re-

●

connected 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 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.

● 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.

● 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.

OPERATING TIPS

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.

●

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 flash (see Page. 3)).

● 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 Control Unit to resume operation.
