Safety instructions
2.1 General safety
ezCaution – Danger of electrocution!
When using the device on boats: If the device is powered by the
mains, ensure that the power supply is protected with a ground
fault interrupter circuit.
zCheck that the voltage specification on the type plate corres-
ponds to that of the energy supply.
zOnly connect the device as follows:
– With the cable supplied (Fig. 12, page 3) to the cigarette
lighter in the vehicle or to a 12/24 V plug socket in the vehicle
– or with the enclosed connection cable (Fig. 1 3, page 3) to
the 120 V AC mains (only
CF-35 , CF-40 , CF-50 , CF-60 ).
zIf the connection cable is damaged, it must be replaced by a
special cord or assembly available from the manufacturer or
service agent.
zDo not pull the plug out of the cigarette lighter or the socket by
the cable.
zPull out the connection cable:
– Before cleaning and maintenance
– After use
– Before changing a fuse
zDisconnect the cooling device and other power consuming de-
vices from the battery before you connect the battery to a quick
charging device. Overvoltage can damage the electronics of the
device.
azElectronic devices are not toys!
Always keep and use the device out of the reach of children.
zDo not operate the device if it is visibly damaged.
zThis device may only be repaired by qualified personnel. Inade-
quate repairs can lead to considerable hazards.
Should your device need to be repaired, please contact DOME-

Operation
5.2 Accessories
If you want to operate the coolers CF-18 and CF-25 from the
220–240 V AC mains, be sure to use the rectifier DOMETIC
CoolPower EPS100.
6 Operation
6.1 Before initial use
INote
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 chapter “Cleaning and maintenance” on page 43).
Mounting the handles
CF-35, CF-40, CF-50, CF-60
The handles are enclosed unassembled. If you wish to attach the
handles, proceed as follows:
➤Make a handle by putting two holders (Fig. 71, page 4) and a
handle (Fig. 72, page 4) together.
➤Fasten the grip with the enclosed screws in the holes provided.
Turning the lid stop around
CF-50, CF-60
You can turn the lid stop around if you want to open the lid from the
other side.
To do this, proceed as follows:
➤Open the lid and pull it out (Fig. 8A, page 5).
➤Turn the lid.
➤Insert the lid in the lid holders on the side opposite the cooler
(Fig. 8B, page 5).

Operation
Selecting the temperature units
CF-25, CF-35, CF-40, CF-50, CF-60
You can switch the temperature display between Celsius and Fahr-
enheit. This is how to do it:
➤Switch on the cooler.
➤Press the “SET” button (Fig. 44, page 4) twice.
➤Use the “UP +” (Fig. 46, page 4) and “DOWN -” (Fig. 47,
page 4) 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
zChoose a well ventilated installation location which is protected
from direct sunlight.
zAllow hot food to cool down first before you place it into the
device.
zDo not open the cooler more often than necessary.
zDo not leave the lid open for longer than necessary.
zDefrost the cooler once a layer of ice forms.
zAvoid unnecessary low temperatures.

Operation
6.3 Connecting the cooler
Connecting to a battery (Vehicle or boat)
The cooler can be operated with 12 V or 24 V DC.
eCaution – Danger of damaging the device!
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 (Fig. 12, page 3) into the
DC voltage socket and also into the cigarette lighter or a 12 V
or 24 V socket.
Connecting to a 120 V AC mains (E.g. in the home or office)
eCaution – Danger of electrocution!
Never handle plugs and switches with wet hands or if you are
standing on a wet surface.
eCaution – Danger of electrocution!
If you are operating your cooler on board a boat from a mains con-
nection of 120 V AC, you must install a residual current circuit
breaker between the 120 V AC mains and the cooler.
Seek advice from a trained technician.
CF-35, CF-40, CF-50, CF-60
The coolers CF-35, CF-40, CF-50, CF-60 have an integrated multi-
voltage power supply with priority circuit for connecting to an AC
voltage source of 120 V. The priority circuit automatically
switches the cooler to mains operation, if the device is connected
to a 120 V AC mains, even if the 12/24 V connection cable is
still attached.
When switching between the AC mains and the battery supply,
the red LED may light up briefly.
_CF-18_60.book Seite 37 Donnerstag, 26. Juli 2007 3:18 15
16

Operation
➤Plug the 120 V connection cable (Fig. 13, page 3) into
the AC voltage socket and connect it to the 120 V AC
voltage mains (only CF-35, CF-40, CF-50, CF-60).
CF-18, CF-25
To operate the coolers CF-18 and CF-25 from the 220–240 V AC
mains, use the rectifier DOMETIC CoolPower EPS100 (accessory).
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.
aCaution – 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).

Operation
This is how to select the battery monitor mode:
CF-25, CF-35, CF-40, CF-50, CF-60
➤Switch on the cooler.
➤Press the “SET” button (Fig. 44, page 4) three times.
➤Use the “UP +” (Fig. 46, page 4) and “DOWN -” (Fig. 47,
page 4) buttons to select the battery monitor mode.
✓The selected mode then appears in the display for a few sec-
onds. The display flashes several times before it returns to the
current temperature.
INote
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.
6.5 Using the cooler
aCaution – 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. Make sure that the device
is sufficiently far away from walls and other objects so that the
air can circulate.
➤Place the cooler on a firm foundation.
Make sure that the ventilation slots are not covered and that the
heated air can dissipate.
INote
Place the cooler as shown (Fig. 1, page 3).If you operate the box
in a different position it can be damaged.
➤Close the cooler, see “Connecting the cooler” on page 37.
INote
If you wish to operate the cooler from the AC mains, set the battery
monitor to the “LOW” position.

6.7 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 cover slightly open. This prevents odour build-up.
6.8 Defrosting the cooler
Humidity can form frost in the interior of the cooling device or on the
vaporiser. This reduces the cooling capacity. Defrost the device in
good time to avoid this.
aCaution – Danger of damaging the device!
Never use hard or pointed tools to remove ice or to loosen objects
which have frozen in place.
To defrost the cooler, proceed as follows:
➤Take out the contents of the cooling device.
➤If necessary, place them in another cooling device to keep them
cool.
➤Switch off the device.
➤Leave the cover open.
➤Wipe off the defrosted water.
