switch is on the main unit of the appliance to operate the appliance in the standard conditions.
• Press the forced operation button, the forced operation is carried out.
• Press the forced operation button once again to stop operation.
• 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
■ 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.
• After supplying power to the main body, keep pressing the forced operation button for about 3 seconds.
• 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.
■ Protection of the evaporator pipe from frosting
• In the temperrature of the indoor pipe is below 0°C after 7 minutes from starting the compressor, the compres-
sor and outdoor fan are stopped, and 3 minutes delay of operating of the compressor, when the temperature of
the indoor pipe is over 7°C, the compressor and the outdoor fan are reoperated.
• Outdoor fan motor stops when indoor pipe temperature is blow 3°C and restarts at the pipe temperature above
6°C or after 90 seconds, if the pipe temperature does not rise to 6°C, outdoor fan motor runs continuously at
even below 3°C.
