CRX50, CRX65 Technical description
6 Technical description
The CoolMatic CRX series cooling appliances can cool products and keep them
cool. Products can be deep-frozen in the freezer compartment. If the refrigerator is
operated without a freezer compartment, frozen products can be stored in the short
term using the fast-cooling function.
All materials used in the refrigerator are compatible for use with foodstuffs.
The refrigerant circuit is maintenance-free.
The cooling device can withstand a short-term inclination of 30°.
The temperature is set using the control panel on the inside left of the refrigerator.
Four temperature ranges from +3 °C (37 °F) to +12°C (54°F), and a fast-cooling
function, are available for selection.

CRX50, CRX65 Installing and connecting the refrigerator
• Keep objects clear of openings in the housing or installation structure (such as
ventilation slots, etc.).
• Condensate is produced when the refrigerator is operating normally. You can
either wipe up the condensate on the floor of the refrigerator in regular intervals,
or drain it through a water drain outlet in the floor of the refrigerator (see chapter
“Mounting the water drain outlet (optional)” on page 17).
7.2 Mounting the water drain outlet (optional)
➤ Connect a hose with an inside diameter of 10 mm (0.4 inch) (not included) to the
water drain outlet.
➤ Lay the refrigerator on its side in order to access the bottom side.
➤ Mount the water drain outlet (fig. 5 2, page 6) aligned to the front or to the
back according to the desired direction.
➤ Remove the water drain plug (fig. 5 1, page 6) inside the refrigerator.
7.3 Installing the refrigerator
Proceed as follows to install the refrigerator:
➤ If you wish to drain the condensate through a hose:
Mount the water drain port (see chapter “Mounting the water drain outlet
(optional)” on page 17)
➤ Undo the transport lock (chapter “Releasing the lock” on page 22).
➤ Open the refrigerator door.
➤ Remove the blanking plugs (fig. 6 2, page 6).
➤ Push the refrigerator into the recess.
➤ Fix the refrigerator in place using suitable screws (fig. 6 1, page 6).
➤ Press the blanking plugs (fig. 6 2, page 6) into the openings.
7.4 Changing the door hinge
You can also change the hinge of the door, so that it opens to the left rather than the
right.
➤ Proceed as shown (fig. 7, page 7 to fig. 9, page 7).

Installing and connecting the refrigerator CRX50, CRX65
7.5 Connecting the refrigerator to DC voltage
NOTICE! MATERIAL DAMAGE
A
The refrigerator can be operated with a 12 V or a 24 V DC voltage supply.
For safety reasons, the refrigerator is equipped with an electronic system to prevent
the polarity being reversed. This protects the refrigerator against reversed polarity
when connecting to a battery and against short circuiting.
The use of a load dump board installed on the compressor control module electronics is mandatory. If one of the components has to be replaced handle them as one
unit. Always replace both components together.
To protect the battery, the refrigerator switches off automatically if the voltage is
insufficient (see table below):
• To avoid voltage drops and loss of performance, keep the
connection cable as short as possible and directly connected from
the power source to the DC wire connection of the unit. Therefore
avoid additional switches, plugs or power strips.
• Disconnect the cooling device and all power source connections
from the battery before you connect the battery to a quick charging
device. Overvoltage can damage the electronics of the device.

CRX50, CRX65 Using the refrigerator
➤ Before starting up the device for the first time, check whether the operating volt-
age and the battery voltage match (see type plate).
➤ Connect your refrigerator to a plug socket which is fuse-protected at 15 A
(at 12 V) or 7.5 A (at 24 V) (fig. a 1, page 8).
➤ Connect the red cable (fig. a rd, page 8) to the positive terminal of the battery.
➤ Connect the black cable (fig. a bk, page 8) to the negative terminal of the
battery.
8 Using the refrigerator
The refrigerator conserves fresh foodstuffs. The freezer compartment conserves
frozen foodstuffs and freezes fresh foodstuffs.
NOTICE! MATERIAL DAMAGE
A
• Do not place any electrical devices inside the cooler. The
only exceptions are devices approved for the purpose by the
manufacturer.
• Ensure that food or liquids in glass containers are not excessively
refrigerated. Liquids expand when they freeze and can therefore
destroy glass containers.
• Food may only be stored in its original packaging or in suitable
containers.
• Make sure that you only put items in the cooler which may be kept at
the selected temperature.
I
NOTE
• Before starting your new refrigerator 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 23).
• Do not use force to press the flap of the freezer.
• Do not pull out the dividing wall if there is ice in the freezer.
• Do not remove the control panel membrane when operating the
refrigerator.

EN
Using the refrigerator CRX50, CRX65
8.1 Energy saving tips
• Choose a well ventilated location which is protected from direct sunlight.
• Allow hot food to cool down first before you put it in the refrigerator.
• Do not open the refrigerator more often than necessary. If the door is left open for
more than 5 minutes, the light starts to flash.
• Do not leave the door open for longer than necessary.
• Defrost your refrigerator as soon as a layer of ice forms.
• Avoid unnecessarily low temperature settings.
• Clean dust and dirt from the condenser at regular intervals.
8.2 Switching on the refrigerator
➤ Switch the refrigerator on by pressing the button.
8
NOTE
I
After switching on, the refrigerator needs some time before the
compressor starts up.
8.3 Setting the temperature
➤ Press the button repeatedly until the desired temperature level is set. The
lower/largest LED is the coldest setting. The upper/smallest LED is the warmest
setting. To switch from the coldest level to the warmest level press the button
again.
I
20
NOTE
The cooling performance can be affected by:
• The ambient temperature
• The amount of food to be conserved
• The frequency with which the door is opened.
If the ambient temperature is at 16 °C (61 °F) to 20 °C (68 °F), set the
refrigerator to at least level 2.
EN
CRX50, CRX65 Using the refrigerator
8.4 Setting the fast cooling function
NOTICE! MATERIAL DAMAGE
A
The option of operating the refrigerator using a fast-cooling function allows temperatures suitable for freezing foods to be reached.
➤ Press the button longer than 3 seconds.
✓ The LED above the button lights up.
➤ Press the button again longer than 3 seconds to operate the refrigerator in
normal mode.
8.5 Conserving foodstuffs
A
• Only use the fast-cooling function when the removable freezer compartment is not being used. Otherwise there is a risk that the freezer
compartment becomes too cold and condensate cannot be prevented from forming on the outside of the refrigerator. The energy
consumption will also increase dramatically.
• Note that bottles and other containers can burst when frozen.
• Note that it is difficult to open the refrigerator directly after closing it.
NOTICE! MATERIAL DAMAGE
• Do not conserve warm foodstuffs in the refrigerator.
• Do not place glass containers containing liquid in the freezer
compartment.
NOTE
I
You can conserve foodstuffs in the refrigerator. The time for which the food can be
conserved in this way is usually stated on the package.
The refrigerator is divided in different zones with different temperatures:
• The colder zones are immediately above the drawers for fruit and vegetables,
near the back wall.
• Observe the temperature information and best before date on the food
packaging.
Food which can easily absorb tastes and odors, as well as liquids and
products with a high alcohol content, should be conserved in air-tight
containers.
