On a regularly basis, ensure the lid seal still fits properly.
Avoid unnecessarily low temperatures.

Connecting the cooling device
Connecting to a battery (vehicle or boat)
The cooling device can be operated with 12 V or 24 V . For safety reasons the cooling device is equipped with
an electronic system to prevent polarity reversal. This protects the cooling device against short-circuiting when
connecting to a battery.
NOTICE! Damage hazard
For protection of the device the DC cable supplied includes a fuse inside the plug. Do not remove the
fused DC plug. Only use the DC cable supplied.
1. Plug the DC connection cable (
(
Fig.
on page 11 4).
2. Connect the connection cable to a DC power outlet.
Connecting to an AC power supply
The cooling device has an integrated multi-voltage power supply with priority circuit for connecting to an AC voltage
source. The priority circuit automatically switches the cooling device to AC operation if the device is connected to an
AC power supply, even if the DC connection cable is still attached.
When switching between the AC power supply and the battery supply, the red LED may light up briefly.
1. Plug the AC connection cable (
2. Connect the connection cable to an AC power outlet.
9.4
Using the battery monitor
The cooling device is equipped with a multi-level battery monitor that protects the vehicle battery against excessive
discharging when the cooling device is connected to the on-board DC supply.
If the cooling device is operated when the vehicle ignition is switched off, the cooling device switches off
automatically as soon as the supply voltage falls below a set level. The cooling device will switch back on once the
battery has been recharged to the restart voltage level.
NOTICE! Damage hazard
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 the "HIGH" mode the battery monitor responds faster than in the LOW and MED modes (see the following table).
