SJ-D30M SJ-D33M FUNCTIONS 1. ADJUSTABLE TEMPERATURE CONTROL (1) Temperature control of freezer Thermostat (senses freezer temperature) operates on ON/OFF switchover to control the compressor and cool air circulating fan , and allows the freezer temperature to keep at a suitable temperature. However adjust the freezer temp. control knob as follows depending upon the storing condition of foods. PURPOSE KNOB SETTING MAX(Coldest) For making ice rapidly or fast freezing. When restocking with fresh food.

SJ-D30M SJ-D33M 2. DEFROSTING (1) No defrosting operation is necessary No defrosting operation is necessary. As this machine is so designed that a built-in evaporator cools air and a fan circulates cooled air, neither the freezer nor the refrigerator is frosted, though the evaporator is frosted. The frosted evaporator is defrosted automatically due to the function of defrosting timer and heater, requiring no defrosting operation. (2) Where is melted frost brought 1.

SJ-D30M SJ-D33M (4) As a reference to determine the causes of trouble, malfunction and phenomena are described below. Refer to the following when repairing. 1. Disconnection of defrost heater As off-cycle defrosting is performed, the defrosting time is extremely prolonged. Each time defrosting is started, the freezer temperature rises and a portion of ice and stored foods are melted. 2. Melted thermo. fuse or opened-circuit due to the defect of defrost thermostat.
