Installing and connecting the refrigerator

CRX

7.6Connecting the refrigerator to DC voltage

ANOTICE!

To avoid voltage drops and loss of performance, keep the connection cable as short as possible and not be interrupted. Therefore avoid additional switches, plugs or power strips.

Disconnect the cooling device and other electric consumers from the battery before you connect the battery to a quick charging device. Overvoltage can damage the electronics of the device.

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.

To protect the battery, the refrigerator switches off automatically if the voltage is insufficient (see table below).

	12 V	24 V
Cut-off voltage	10.4 V	22.8 V
Cut-in voltage	11.7 V	24.2 V

Determine the required cross section of the cable in relation to the cable length according to fig. d, page 10.

Key to fig. d, page 10:

Coordinate axis	Meaning	Unit
l	Cable length	m
	Cable cross section	mm²

ANOTICE!

Make sure the polarity is correct.

Before starting up the device for the first time, check whether the operating voltage 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. e 1, page 10).

7.7Connecting the refrigerator to AC voltage

DDANGER! mortal danger!

Never handle plugs and switches with wet hands or if you are standing on a wet surface.

If you are operating your refrigerator on board a boat with an

AC mains connection using a shore connection, you must install a residual current circuit breaker between the AC mains supply and the refrigerator.

Seek advice from a trained technician.

CRX50ACDC, CRX65ACDC, CRX80ACDC, CRX110ACDC, CRX140ACDC

Proceed as follows when you connect the refrigerator to the AC supply:

Plug the connector into the AC socket (fig. f 1, page 11).

CRX50DC, CRX65DC, CRX80DC, CRX110DC

You can connect the refrigerator to 100 – 240 Vw AC power if you use the MPS35 rectifier (accessory).

The MPS35 rectifier features a priority circuit which conserves the battery connected. When a 100 – 240 Vw mains connection is used, the rectifier automatically switches from battery to mains operation.

When disconnected from the 100 – 240 Vw mains supply, the rectifier automatically switches back to battery operation. Mains operation via the rectifier always takes priority over battery operation.

Proceed as follows when you connect the refrigerator to the AC supply:

Attach the rectifier on the back of the refrigerator.

Connect the rectifier as shown in fig. g, page 11.

Connect the refrigerator to the rectifier (fig. g 2, page 11):

8Using the refrigerator

The refrigerator conserves fresh foodstuffs. The freezer compartment conserves frozen foodstuffs and freezes fresh foodstuffs.

ANOTICE!

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.

INOTE

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 28).

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.

8.1Energy 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.
