6. BATTERY MONITOR
The AK 15L Fridge/Freezer is equipped with a multi-level battery monitor that protects your
vehicle battery against excessive discharging when the device is connected to the on-board DC
supply.
If the fridge is operated when the vehicle ignition is switched off, the cooler switches off
automatically as soon as the supply voltage falls below a set level. The cooler will switch back
on once the battery has been recharged to the restart voltage level. The compressor will start up
again automatically when the voltage goes back to normal values.
Note: these values are measured at control unit input and/or on the DC socket.
It is possible to set three different battery protection threshold levels:
The device is preset with a medium battery protection level.
To enter the menu, switch the refrigerator on by pressing the On/Off button.
Press the SET button to access the battery protection level settings. The current setting will start
to flash on the display.
Press the UP or DOWN button to scroll through the three different settings.
Without having to press any other button to confirm, the display will automatically save the setting
and exit programming mode.
