Operation
➤ 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 (only CF-35, CF-40, CF-50, CF-60).
CF-18, CF-25
To operate the coolers CF-18 and CF-25 from the 100–240 V AC
mains, use the rectifier purchased from DOMETIC.

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
Caution – 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).
