1.5 Connecting the cooler
Connecting to a battery (vehicle or boat)
The cooler can be operated with 12 V = or 24 V =.NOTICE! The danger of damage!
Disconnect the cooler and other consumer units from the battery before you connect the battery to a quick charging device. Overvoltage can damage the electronics of the device.
For safety reasons, the cooler is equipped with an electronic system to prevent polarity reversal. This protects the cooler against short-circuiting when connected to a battery.
• Plug the 12/24 V connection cable into the DC voltage socket and also into the cigarette lighter or a 12 V or 24 V socket.

Connecting to 100-240V AC power supply mains (e.g. at home)
Remark: be fit for AC/DC type)
DANGER! Danger of electrocution!
Never handle plugs and switches with wet hands or if you are standing on a wet surface.
If you are operating your cooler on board a boat from a mains AC power supply connection of 100 – 240 V, you must install a residual current breaker between 100 – 240 V AC mains and the cooler. Seek advice from a trained technician.
The cooler must only be supplied at safety extra-low voltage corresponding to the marking on the device.
Plug the 100-240 V connection cable into the 100 – 240 V AC voltage mains and connect it into the AC voltage mains.
1.6 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’s ignition is switched off, the cooker 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.
NOTICE! The 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 battery is recharged.
In “H” mode, the battery monitor responds faster than in modes “L” and “M” (see the following table}.

This is how to select the battery monitor mode:

• Switch on the cooler.
• Press the “SET” button 5x (but when selecting one room, that will be 4x).
• Use the “UP +” or “DOWN –” buttons to select the battery monitor mode.

The selected mode appears in the display for a few seconds and will be applied automatically. The display flashes several times before it returns to the current temperature.
NOTE When the cooler is supplied by the starter battery of a car, select the battery monitor mode “H”. If the cooler is connected to a supply battery, the battery monitor mode “L” will suffice. If you wish to operate the cooler from an AC power supply, set the battery monitor to “L” position.
1.7.1 Using the cooler
NOTICE! The danger of overheating!
Ensure at all times that there is sufficient ventilation so that heat that is generated during operation can dissipate. Ensure that ventilation slots are not covered.
