OPERATION
Starting the Appliance
If the refrigerator has been transported on its side, allow 3 hours before applying power. This
provides time for any oil trapped in the cylinder to settle back into the oil sump. Once ready,
connect the 12 or 24 VDC power source and the refrigerator will automatically turn on within
about 1 minute. The freezer compartment will cool first and reach below freezing temperature
within 1 hour. The refrigerator (fresh food) compartment might take up to 4 hours to reach
proper temperature, depending on ambient conditions. The refrigerator might cycle on and off
during this initial cool down period, this is normal.
Temperature Control
The temperature is automatically controlled by a digital thermostat. No user adjustment is
necessary or possible. The refrigerator will automatically maintain temperature within the limits
in the table below as long as the ambient temperature is between 60 & 90F (16 & 32C).
Insertions of large warm food loads will temporarily result in higher temperatures.
