6.2 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 to
keep cool.
• Do not open the cooling device more often than necessary.
• Do not leave the cooling device open for longer than necessary.
• Defrost the cooler once a layer of ice forms.
• Avoid unnecessarily low temperatures.
6.3 Connecting the cooler
Connecting to a battery (Vehicle or boat)
The cooler can be operated with 12 V or 24 Vg.
A
For safety reasons the cooler is equipped with an electronic system to prevent
polarity reversal. This protects the cooler against short-circuiting when connecting to
a battery.
Using the fused DC plug
A
➤Plug the DC connection cable (fig. 12, page 7) into the DC voltage socket of
the cooler (fig. 43, page 12).
➤Connect the connection cable to a DC power outlet.
NOTICE! DAMAGE HAZARD
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! 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.
DometicCFF20-35-45-75DZ_OPM_4445103133_APAC(en)_202x-xx-xx.book Seite 18 Dienstag, 20. Oktober 2020 4:16 16

CFF20, CFF35, CFF45, CFF70DZ Operation
19
Connecting to an AC power supply (e.g. in the home or office)
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 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.
➤Plug the AC connection cable (fig. 13, page 7) into the AC voltage socket of
the cooler (fig. 41,page 12).
➤Connect the connection cable to an AC power outlet.
DANGER! ELECTROCUTION HAZARD
Failure to obey these warnings will result in death or serious injury.
• Never handle plugs and switches with wet hands or if you are stand-
ing on a wet surface.
• If you are operating your cooler on board a boat from a AC power
supply, you must install a residual current circuit breaker between the
AC power supply and the cooler.
Seek advice from a trained technician.

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
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
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. 35, page 11):
–CFF20, CFF35, CFF45: Three times.
–CFF70DZ: Four times.
➤Use the “UP +” (fig. 37, page 11) or “DOWN –” (fig. 36, page 11) buttons to
select the battery monitor mode.
✓Display will be as follows:
Lo (LOW), ΠEd (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.
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.
