7.5 Connecting the refrigerator

Connect the refrigerator to DC power

The refrigerators can be operated with 12V = - or with 24V = -

NOTICE!

To avoid voltage drops and loss of performance, keep the cable as short as possible and avoid joins.

For this reason avoid additional switches, plugs or multi-way adapters.

Determine the required cross section of the cable in relation to the cable length according to fig. 15, page 9.

Key for fig. 15, page 9

Co-ordinate axis	Explanation	Unit
l	Cable length	m
∅	Cable cross section	mm2

NOTICE!

Make sure that the polarity is correct.

Before starting up the appliance for the first time, check whether the operating voltage and the battery voltage match (see type plate).
Connect the refrigerator

• as directly as possible to the poles of the battery or
  to a 12 or 24V = - socket.

Fit a fuse in the positive wire of 15 A (for 12V ) or 7.5 A (for 24V ) (fig. 16 1, page 9).

Connect the red cable (fig. 16 rt, page 9) to the positive terminal of the battery.
Connect the black cable (fig. 16 sw, page 9) to the negative terminal of the battery.

NOTICE!

• Disconnect the refrigerator and other electric loads from the battery before connecting the battery to a quick charging device.
• Overvoltage can damage the appliance electronics.

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

Connecting the refrigerator to AC power (accessory)

NOTE

The CR140 and all US versions are available in DC/AC version only. Without using a rectifier, these refrigerators can be operated using a 110 - 240 V AC current source, in addition to a 12 or 24 V DC current source.

You can connect the refrigerator to AC power if you use a rectifier (accessory):

110-240V:MPS35

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 refrigerator on board a boat with a mains connection of 230V from the land, you must install a residual current circuit breaker between the 230V mains supply and the refrigerator.

Seek advice from a trained technician.

NOTE

Always connect the refrigerator to the rectifier. Otherwise the priority circuit for the refrigerator will be disabled.

The priority circuit reduces the load on a connected battery by the rectifier always switching to mains operation if AC power is connected.

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

Fix the rectifier as shown in the location foreseen, behind the refrigerator (fig. 17, page 10).

Protect the AC circuit using a slow-blow fuse (250 V/4 A).
Connect the power cable to the AC power supply.

Red cable: positive battery terminal
- Black cable: negative battery terminal

8 Using the refrigerator

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 care" on page 50).

8.1 Energy saving tips

• Choose a well ventilated installation 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.
• 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 Using the refrigerator

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

NOTICE!

• 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 cooled. Liquids expand when they freeze and can thus destroy the glass containers.
• Food may only be stored in its original packaging or in suitable containers.
• Ensure that the objects placed in the refrigerator are suitable for cooling to the selected temperature.

Switch the refrigerator on by turning the temperature control (fig. 6 1 page 5) clockwise.

NOTE

After switching on, the refrigerator requires approx. 60 s until the compressor starts up.

Setting the temperature

You can set the temperature to any level using the control knob. The built-in thermostat regulates the temperature as follows:

• 1 = least cooling
• 7 = most cooling

NOTE

The cooling capacity can be influenced by:

the ambient temperature
the amount of food to be conserved
the frequency with which the door is opened.

Conserving foodstuffs

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.

NOTICE!

Do not conserve warm food in the refrigerator.

Do not place glass containers containing liquid in the freezer compartment.

NOTE

Food which can easily absorb tastes and odours and liquids and products with a high alcohol content should be conserved in airtight containers.

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.
  Observe the following when using the refrigerator:

• Never re-freeze products which have started defrosting or have been defrosted, but consume them as soon as possible.

• Wrap food in aluminium foil or cling film and shut in in a suitable box with a lid. This ensures that aromas, the shape and the freshness will be better conserved.

Defrosting the refrigerator

The appliance has two options to remove the condensation resulting from operation:

• pass it directly outside:

Remove the drip-tray (fig. 1, page 7).

Connect a hose (fig. 10 2, page 7) to the outlet connections (fig. 10 1, page 7).

collect in the drip-tray:

Empty the drip-tray (fig. 11 1, page 7) as required.

Defrosting the freezer

NOTICE!

Never use mechanical tools to remove ice or to loosen objects stuck to the device. The only exceptions are devices approved for the purpose by the manufacturer.

To defrost the refrigerator, proceed as follows:

Take the contents out.
If necessary, place the contents in another cooling appliance, to keep them cool.
Set the temperature control knob to "0".
Leave the door open.

Switching off and storing the refrigerator

If you do not intend to use the refrigerator for a long time, proceed as follows:

Set the temperature control knob to level "0".

Disconnect the power cable from the battery or pull the AC cable plug out of the rectifier.
Clean the refrigerator (see chapter "Cleaning and care" on page 50).
Turn the locking wheel (fig. 9 1, page 6) anti-clockwise to the end stop ("Vent").
Close the door until it latches in.
The door stays open thus preventing smells from arising.

Replacing the interior light

If the interior light in the refrigerator is faulty, you can change the LED lamp (DC 12 - 24 V, 0.3 W). When changing the lamp, only use LEDs which can be run with 12 V and 24 V.

Remove the cover.

Pull the lamp (fig. 6 4, page 5) out of the sheet metal straps.
Slide in the new lamp between the sheet metal straps, until it snaps into place.

Change the fuse (only DC/AC refrigerators).

If the fuse in the rectifier is faulty too, you can replace this too.

Lever the fuse compartment (fig. 17 3, page 10) open with a screwdriver.
Replace the fuse (250 V/4 A).
Close the fuse compartment again.

9 Cleaning and care

NOTICE!

• Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the refrigerator.
• Never use hard or pointed tools to remove ice or to loosen objects which have frozen in place.

As soon as the refrigerator becomes dirty, clean it with a damp cloth.
Make sure that no water drips into the seals. This can damage the electronics.

Wipe the refrigerator dry with a cloth after cleaning.
