5. OPERATION DETAILS

(1) The function of main control

1. Time Delay Safety Control

• 3min

...

The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle.

(Protection of compressor)

• 3sec

...

The indoor fan is ceased for 1~3 seconds to prevent relay noise. (Protection of fan relay and micro chip)

• 1min

...

The 4-way valve is ceased for 30 sec. to prevent the refrigerant-gas abnormal noise when the Heating operation is OFF or switched to the other operation mode.

2. Airflow Direction Control

• This function is to swing the louver left and right automatically and to set it at the desired position.

• The procedure is as the following. 1st : Press the ON/OFF Button to operate the product.

2nd : Press the Airflow Direction Control Button to swing the louver left and right automatically.

(Remote controller)

3rd : Repress the Airflow Direction Control Button to set the louver as the desired position.

• The indoor fan stops until the evaporator piping temperature will be reached to 28°C.

• During heating operation, if piping temperatures fall below 26°C fan stops.

• The operation diagram is as following.

7. Defrost Control

• Defrost operation is controlled by timer and sensing temperature of outdoor pipe.

• The first defrost starts only when the outdoor pipe temperature falls below -6°C after 45 minutes passed from starting of heating operation and more than.

• Defrost ends after 10 minutes pass from starting of defrost operation or when the outdoor pipe temperature rises over 12°C even if before 10 minutes.

• The second defrost starts only when the outdoor pipe temperature falls below -6°C after 45 minutes pass from ending of the first defrost and more than.
