Under Voltage Shutdown
The compressor electronics includes an undervoltage shutdown feature. If the input voltage to the
appliance falls below 9.6V (in 12 or 24V mode). Once the voltage increases above 10.9V at the
electronics, the compressor will resume normal operation.
OPERATION
Starting the Appliance
After the appliance has been properly connected to the 12 or 24 VDC power source, the compressor will automatically
turn on and the cabinet will begin cooling.
Allow the cabinet to cool for at least 4 hours prior to adding items.
Temperature Control
The temperature within the appliance is controlled by the thermostat situated on the lower front of the cabinet. When you
first start the appliance, we suggest that you turn the thermostat to a medium setting. The correct internal temperature
setting can be found by measuring the temperature of the central or middle portion in the
appliance. At higher altitudes, the thermostat will run colder
Adjustments
As the ambient temperature changes from summer to winter, it may be necessary to adjust the thermostat to achieve the
proper internal temperature setting. If the room/ambient temperature approaches the appliance’s internal operating
temperature, the appliance will not function as it should. The appliance will tend to run colder during these conditions,
and it may be necessary to turn the thermostat to a warmer setting (towards the ‘min’). If the room/ambient temperature
exceeds 100
o
F (38
o
C), the appliance will not function as it should. The appliance will tend to run warmer, and it may
be necessary to turn the thermostat to a colder setting (towards the ‘MAX’ setting).
Energy Consumption
The best energy consumption is with warmer thermostat settings and cooler ambient. This has a strong impact on
energy use. To achieve the lowest energy consumption, locate the fridge in a cool room and set the thermostat to the
warmest setting. Of course, feel free to set the thermostat colder if you prefer, but know that this strongly affect energy
use.
A fridge running at -15C in a 25C room, will use ½ the energy of a fridge running at -20 in a 36C room.
As the ambient temperature Opening and Closing the Lid
The lid is fitted with a uniform sealing strip to prevent warm air and moisture from entering the appliance compartment.
Be sure that the lid and the lid seal is free from obstructions and forms a complete seal around the rim of the cabinet.
Overfilling and/or unlevel installation of the appliance will prevent a good seal.
NEVER USE EXCESSIVE FORCE ON THE HANDLE TO OPEN THE LID!
When the lid is opened, the air inside the appliance becomes slightly warmer and expands. When the lid is closed
again, the air is cooled quickly and contracts. This may lead to the creation of a vacuum which makes it more
difficult to open the lid again immediately. This is quite normal. Wait for a few moments until the vacuum has
equalized and then open gently. Also, ensure that the cabinet is not locked.
