OPERATION PROCEDURE[CHARACTERISTICS OF THE COOLINGOPERATION (COOLING OPERATION ANDAUTOMATIC COOLING OPERATION)]• If the COOLING OPERATION is used when theindoor temperature is low, frost forms on the heatexchanger of the indoor unit. This can decreasethe cooling capacity. In this case, the systemautomatically switches to DEFROST OPERA-TION for a while.Low airflow rate is used prevent humidity increase.• When the outdoor temperature is high, it takessome time until the indoor temperature reachesthe set temperature.[CHARACTERISTICS OF THE HEATINGOPERATION (HEATING OPERATION ANDAUTOMATIC HEATING OPERATION)]START OF OPERATION• It generally takes a longer time for HEATINGOPERATION to reach the set temperature com-pared to COOLING OPERATION. It is advisableto start operation in advance using TIMER OPER-ATION.Perform the following operation to prevent heat-ing capacity decrease and discharge of cool air.AT THE START OF OPERATION AND AFTERDEFROSTING OPERATION• A warm air circulating system is employed, andtherefore it takes some time until the entire roomis warmed up after the start of operation.• The indoor fan runs to discharge a gentle windautomatically until the temperature inside the airconditioner reaches a certain level. At this time,the remote controller displays “ ”. Leave itas it stands and wait for a while.• The remote controller displays the airflow ratethat is set.DEFROST OPERATION (Frost removal oper-ation for the outdoor unit)• As the frost on the coil of an outdoor unit increase,heating effect decreases and the system goesinto DEFROST OPERATION.• The indoor unit fan stops and the remote control-ler display shows “ ”.The remote controller displays the airflow ratethat is set.• After 6 to 8 minutes (maximum 10 minutes) ofDEFROST OPERATION, the system returns toHEATING OPERATION.6.
