OPERATION Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). To Select Mode Operation 1 Press the START/STOP button (Fig. 5 J). 2 Press the MASTER CONTROL button (Fig. 5 E) to select the desired mode. The indoor unit’s OPERATION indicator lamp (red) (Fig. 3 5) will light. The air conditioner will start operating.
OPERATION Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). When set to AUTO: * Heating : Fan operates so as to optimally circulate warmed air. However, the fan will operate at very low speed when the temperature of the air issued from the indoor unit is low. Cooling : As the room temperature approaches that of the thermostat setting, the fan speed becomes slower.
AUTO: COOLING MODEL ● 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.
TIMER OPERATION Before using the timer function, be sure that the Remote Control Unit is set to the correct current time (see page 5). To Use the ON timer or OFF timer 1 2 Press the START/STOP button (Fig. 5 J) (if the unit is already operating, proceed to step 2). The indoor unit’s OPERATION indicator lamp (red) (Fig. 3 5) will light. Press the TIMER button (Fig. 5 H) to select the OFF timer or ON timer operation. Perform steps 2 and 3.
SLEEP TIMER OPERATION Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). Unlike other timer functions, the SLEEP timer is used to set the length of time until air conditioner operate is stopped. To Use the SLEEP timer While the air conditioner is operating or stopped, press the SLEEP button (Fig. 5 D). Both the indoor unit’s OPERATION indicator lamp (red) (Fig. 3 5) and the TIMER indicator lamp (green) (Fig. 3 6) will light.
ADJUSTING THE DIRECTION OF AIR CIRCULATION Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). Vertical (up-down) direction of airflow is adjusted by pressing the Remote Control Unit’s AIR FLOW DIRECTION 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.
SWING OPERATION Begin air conditioner operation before performing this procedure. To select SWING Operation Press the SWING LOUVER button (Fig. 5 L). The SWING indicator lamp (orange) (Fig. 3 7) will light. In this mode, the Air Flow Direction Louvers will swing automatically to direct the airflow both up and down. To Stop SWING Operation Press the SWING LOUVER button (Fig. 5 L) once again. The SWING indicator lamp (orange) (Fig. 3 7) will go out.
CLEANING AND CARE ● Before cleaning the air conditioner, be sure to turn it off and disconnect the power supply cord.

TROUBLESHOOTING Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). WARNING! In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power Supply Plug or turn off the circuit breaker, 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 your circuit breaker to ensure that power is completely off.
