6.1 Before initial use
NOTE
Before starting your new cooler for the first time, you should clean it inside and outside with a damp cloth for
hygienic reasons (please also refer to the “cleaning and maintenance” on page 19).
The lid can be removable, or can be opened from either side in an instant, 2 ways opening – left or right
Selecting the temperature units
Temperature display units can be switched between Celsius and Fahrenheit as follows:
• Switch on the cooler.
• Press the “SET” button (fig.
4, page 9) twice.
• Use the “UP+ (fig.
6, page 9)” or “DOWN – (fig
7, page 9)“ buttons to select Celsius or Fahrenheit.
• The selected temperature units then appear in the display for a few seconds. The display flashes several
times before it returns to the current temperature.
6.2 Energy saving tips
• Choose a well ventilated installation location which is protected against direct sunlight
• Allow warm food to cool down first before placing it in the device to keep cool.
• Do not open the cooling device more often than necessary.
• Do not leave the cooler unit open for longer than necessary.
• Defrost the cooler once a layer of ice forms.
• Avoid unnecessary low temperatures.
6.3 Connecting the cooler
Connecting to a battery (Vehicle or boat)
The cooler can be operated with 12 V or 24 V
Notice! 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 the polarity reversal. This
protects the cooler against short-circuiting when connecting to a battery.
• Plug the 12/24 V connection cable into the device DC voltage socket (fig.
2, page 7) and also into a 12 V
or 24 V cigarette lighter socket.
6.4 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.
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer be full 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).
The battery monitor mode can be selected as follows:
Switch on the cooler.
• Press the “SET” button (fig.
4, page 9) three times
• Use the “UP+ (fig.
6, page 9)” or “DOWN – (fig.
7, page 9 )” buttons to select the battery monitor mode.
• Digital display will be as follows:
• Lo (LOW), Md(MED), Hi(HIGH)
The selected mode then appears in the display for a few seconds. The display flashes several times before
it returns to the current temperature.
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.
