CoolFreeze
7.4 Using the battery monitor
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).

NOTE
When the cooler is supplied by the starter battery, select the battery
monitor mode "HIGH". If the cooler is connected to a supply battery,
the battery monitor mode "LOW" will suffice.
If you wish to operate the cooler from the AC mains, set the battery
monitor to the "LOW" position.
