Using The Battery Monitor - Dometic COOLFREEZE CF35 Notice D'utilisation

Operation
The coolers have an integrated multi-voltage power supply with priority circuit for
connecting to an AC voltage source of 120 V. The priority circuit automatically
switches the cooler to mains operation, if the device is connected to a 120 V AC
mains, even if the 12/24 V connection cable is still attached.
When switching between the AC mains and the battery supply, the red LED may
light up briefly.
➤ Plug the 120 V connection cable (fig. 1 3, page 3) into the AC voltage socket
and connect it to the 120 V AC voltage mains.

Using the battery monitor

The device 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
12/24 V supply.
If the cooler 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.
A
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer be
fully charged. Avoid starting repeatedly or operating current consumers
without longer charging phases. Ensure that the battery is recharged.
In "HIGH" mode, the battery monitor responds faster than at the levels "LOW" and
"MED" (see the following table).
