7.2 Energy saving tips
•Choose a well ventilated location which is protected from direct sunlight.
•Allow warm food to cool down first before placing it in the cooling device.
•Do not open the cooling device more often than necessary.
•Do not leave the cooling device open for longer than necessary.
•Defrost the cooling device once a layer of ice forms.
•Avoid unnecessarily low temperatures.
7.3 Connecting the cooler
Connecting to a battery (vehicle or boat)
The cooler can be operated with 12 Vgor 24 Vg.
A
For safety reasons the cooler is equipped with an electronic system to prevent
polarity reversal. This protects the cooler againstshort-circuiting when connecting to
a battery.
Using the fused DC plug
A
➤Plug the DC connection cable (fig. 12, page 6) into the DC power supply inlet
of the cooler (fig. 51, page 11/fig. 63, page 11).
➤Connect the connection cable to a DC power outlet.
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.
NOTICE! Danger of damage!
For protection ofthe device the DC cable supplied includes a fuse inside
the plug. Do not remove the fused DC plug.
Only use the DC cable supplied.

15
Connecting to an AC power supply (e.g. in the home or office)
(CF35, CF40, CF50)
D
The coolers have an integrated multi-voltage power supply with priority circuit for
connecting to an AC voltage source. The priority circuit automatically switches the
cooler to power supply 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.
➤Plug the AC connection cable (fig. 13, page 6) into the AC power supply inlet
of the cooler (fig. 61,page 11).
➤Connect the connection cable to the AC power outlet.
7.4 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 an on-board
DC 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
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 power supply
connection of 100 – 240 Vw, you must install a residual current
circuit breaker between the 100 – 240 V AC power supply and the
cooler.
Seek advice from a trained technician.
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer be
fully charged. For in-vehicle installations, avoid repeated starting and
shutting off of the engine. Allow the vehicle to recharge the battery
before powering the cooler on.

7.5 Using the cooler
A
➤Place the cooler on a firm foundation.
Make sure that the ventilation slots are not covered and that the heated air can
dissipate.
I
➤Close the cooler, see chapter “Connecting to a battery (vehicle or boat)” on
page 14.
I
CF18
➤Set the slide switch (fig. 34, page 9) to "HIGH" when power is supplied by
your vehicle's starter battery.
➤Set the slide switch (fig. 34, page 9) to "LOW" when power is supplied by an
external DC power supply source.
✓The “POWER” LED is lit green.
✓The cooler starts cooling the interior.
✓When the cooling temperature has been reached, the “POWER” LED is lit yellow.
NOTICE! Danger of overheating!
Ensure at all times that there is sufficient ventilation so that the heat that
generated during operation can dissipate. Ensure that the ventilation
slots are not covered. The cooler MUST maintain a MINIMUM of 50 mm
away from walls or similar surfaces which could restrict important air flow
requirements of the cooling system.
NOTE
Place the cooler as shown (fig. 1, page 6). If you operate the box in a
different position it can be damaged.
NOTE
If you wish to operate the cooler from the AC power supply, set the
battery monitor to the “LOW” position.

7.7 Using the Emergency Switch
The emergency override switch ((fig. 52, page 11 and fig. 64, page 11) is
located in the connection panel.
➤For normal operation the switch should be in the NORMAL USE position.
➤In the unlikely event of an electronic control failure slide the switch to
EMERGENCY OVERRIDE.
I
7.8 Switching off the cooler
➤Empty the cooler.
➤Switch the cooler off.
➤Pull out the connection cable.
If you do not want to use the cooler for a longer period of time:
➤Leave the lid slightly open. This prevents odor build-up.
7.9 Defrosting the cooler
Humidity can form frost in the interior of the cooling device or on the evaporator. This
reduces the cooling capacity. Defrost the device in good time to avoid this.
A
To defrost the cooler, proceed as follows:
➤Remove the contents.
➤If necessary, place them in another cooling device to keep them cool.
➤Switch off the device.
➤Leave the lid open.
➤Wipe off the defrosted water.
NOTE
In this position the appliance will run all the time and will therefore per-
form as a freezer only.
NOTICE! Danger of damage!
Never use hard or pointed tools to remove ice or to loosen objects
which have frozen in place.
