Operation Details
(1) The function of main control
1. Time Delay Safety Control
• 3min… The compressor is ceased for 3minutes to balance the pressure in the refrigeration cycle.
(Protection of compressor)
• 5sec… Vertical air flow direction control louvers open in 5 seconds to prevent noise between louvers and wind.
• 30sec… The 4-way valve is ceased for 30sec. to prevent the refrigerant-gas abnormal noise when the Heating
operation is OFF or switched to the other operation mode while compress is off.
While compressor is running, it takes 3~5 seconds to switch.
2. Airflow Direction Control
• This function is to swing the louver up and down 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 up and down automatically.
