Forced Operation ( C/O Model)
• To operate the appliance by force in case that the remote controller is lost, the forced operation selection switch
is on the main unit of the appliance to operate the appliance in the standard conditions.
• When the power is supplied while the slide switch is on the forced operation position, or when the slide switch
position is switched to the Auto Restarting position (or test operation) or switched from the remote control posi-
tion to the forced operation position while the power is on, the forced operation is carried out.
tion to the forced operation position while the power is on, the forced operation is carried out.
• When the slide switch position is switched from the forced operation position to the Auto Restarting position or
the remote control position, the forced operation is canceled and the appliance stops operating.
• The forced operation is carried out in cooling mode with the setting temperature 22°C and the high speed of air-
flow.
• While in forced operation, the key input by the remote controller has no effect and the buzzer sounds 10 times
to indicate the forced operation.
Forced Operation ( H/P Model)
• To operate the appliance by force in case that the remote controller is lost, the forced operation selection switch
is on the main unit of the appliance to operate the appliance in the standard conditions.
• When the power is supplied while the slide switch is on the forced operation position, or when the slide switch

tion to the forced operation position while the power is on, the forced operation is carried out.
• When the slide switch position is switched from the forced operation position to the Auto Restarting position or
the remote control position, the forced operation is canceled and the appliance stops operating.
• The forced operation is carried out in cooling mode with the setting temperature 22°C and the high speed of air-
flow.
• In the forced operation mode, the indoor fan is operated at low speed for around 15 sec and then the operation
condition is set according to the intake air temperature as follows.
24°C
Intake Air Temp
=> Cooling Mode Operation, 22°C, High Speed
21°C
Intake Air Temp < 24°C => Dehumidification Operation, 23°C, High Speed
Intake Air Temp < 21°C
=> Heating Mode Operation, 24°C, High Speed
• While in forced operation, the key input by the remote controller has no effect and the buzzer sounds 10 times
to indicate the forced operation.
Test Operation Control
• To check the condition of the installation when installing the appliance, the appliance is operated at cooling
mode, high speed of airflow, compressor-on for 18 min without controlling the room temperature.
• Only when the slide switch on the main unit is switched from the remote control position to the test operation
position, test operation is carried out.
• When the slide switch position is switched to the remote control position while in test operation, the test opera-
tion is canceled and the appliance is stopped. When switched to the forced operation position, the test opera-
tion is canceled and the forced operation is carried out.
tion is canceled and the forced operation is carried out.
• While in test operation, a key can be input by the remote controller.
When a key (operation start/stop, operation mode selection, airflow speed selection, temperature control, Jet
Cool) is input by the remote controller, the test operation is canceled and the appliance is operated according to
the setting by the remote controller.
Cool) is input by the remote controller, the test operation is canceled and the appliance is operated according to

Remote Control Operation Mode
• When the remote control is selected by the slide switch on the main unit, the appliance operates according to
the input by the remote controller.
Protection of the evaporator pipe from frosting
• If the indoor pipe temp is below 0°C in 7 min after the compressor operates without any pause while in cooling
cycle operation mode, the compressor and the outdoor fan are turned off in order to protect the indoor evapora-
tor pipe from frosting.
tor pipe from frosting.
• When the indoor pipe temp is 7°C or higher after 3 min pause of the compressor, the compressor and the out-
door fan is turned on according to the condition of the room temperature.
Buzzer Sounding Operation
• When the appliance-operation key is input by the remote controller, the short “beep-beep-” sounds.
• When the appliance-pause key is input by the remote controller, the long “beep—” sounds.
• When a key is input by the remote controller while the slide switch on the main unit of the appliance is on the
forced operation position, the error sound “beep-beep-beep-beep-beep-” is made 10 times to indicate that the
remote control signal cannot be received.
remote control signal cannot be received.
Self Diagnosis Operation
Thermistor Error Indicator
• When the indoor pipe sensor or the room temperature sensor is open or is shorted, the error is indicated.
• To indicate the error, the operation LED (or the cooling LED) flashed at 3 sec interval.
• When the error is cleared, the LED stops flashing, the operation (or cooling) LED is on.
• While in appliance pause, the error is not indicated.
• Since the airflow quantity and speed are controlled by the adjustment of the vane angle using the Wind-up
effect, you can enjoy the natural and pleasant wind uniformly at any location in the room.
• Since the indoor outflow air is sucked again by the upper/lower vanes, the indoor temperature drop is mini-
mized and the pleasant humidity is maintained.
