NOTE:After changing an LP tank, or after a long shut off period, the gas line is likely to be filled with air. You may have to repeat the lighting procedure several times to purge the air out of the gas lines.

ELECTRIC OPERATION

Check to be sure the power cord is properly connected to the power supply. If the refrigerator is equipped for 12 volt DC operation, the tow vehicle engine should be running to prevent discharging the battery.

The thermostat can be adjusted between “MAX” and “OFF” to obtain the desired cabinet temperature. The closer the knob is to “MAX”, the colder the cabinet temperature. The closer the knob is to

“OFF”, the warmer the cabinet temperature.

When the thermostat reaches the set temperature, it will cut the burner back to bypass or, in electric operation, shut off the heating element.

The setting of the thermostat is not critical, but we recommend it be adjusted to maintain a dry frost on the cooling fins. Adjust the thermostat knob closer to “MAX” when the outside temperature becomes warm.
