Connecting to a battery
The cooling device can be operated with a 12 V or 24 V DC voltage supply.
To avoid voltage loss and therefore a drop in performance, the cable should be kept as short as possible and should not be interrupted if this is possible.
For this reason avoid additional switches, plugs or power strips.
Determine the required cross section of the cable in relation to the cable length according to fig. 7, page 5.
Key for fig. 7, page 5
| Co-ordinate axis Meaning Unit | ||
| I Cable length m | ||
| ØCable cross section mm2 | ||
Caution!
Make sure that the polarity is correct.
- Before starting up the device for the first time, check whether the operating voltage and the battery voltage correspond (see type plate).
Connect the cooling device
- As directly as possible to the pole of the battery or
- To a plug socket which is fused with at least 15 A (at 12 V) or 7.5 A (at 24 V).
Caution!
Disconnect the cooling device and other power consuming devices from the battery before connecting the battery to a quick charging device.
Overvoltage can damage the electronics of the device.
The cooling device is equipped with an electronic device to protect against reversing the polarity and short circuits when connecting to a battery.
To protect the battery, the cooling device switches off automatically if the voltage is insufficient (see table below).
| 12 V 24 V | ||
| Switch-off voltage | 10.4 V 22.8 V | |
| Switch-on voltage | 11.7 V | 24.2 V |
Connecting to 230 V mains supply
Danger of fatal injuries!
Never handle plugs and switches with wet hands or if you are standing in a puddle.
If you are operating your cooling device on board a boat with a mains connection of 230V from the land, you must install a ground protection circuit breaker between the 230V mains supply and the cooling device.
Seek advice from a trained technician.
To operate the cooling device with a 230V mains supply, use an EPS-100 W or MPS-35 MOBITRONIC rectifier.
7 Operation
Before starting your new cooling device 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 33).
7.1 Energy saving tips
- Choose a well ventilated installation location which is protected against direct sunlight.
- Allow food to cool down first before placing it in the device.
- Do not open the cooling device more often than necessary.
- Do not leave the door open for longer than necessary.
- Defrost the cooling device as soon as a layer of ice forms.
- Avoid unnecessarily low temperatures.
- Clean the condenser of dust impurities at regular intervals.
7.2 Using the cooling device
The cooling device conserves fresh foodstuffs. The freezer compartment conserves frozen foodstuffs and freezes fresh foodstuffs.
Caution!
Ensure that food or liquids in glass containers are not excessively refrigerated.
Liquids expand when they freeze and can thus destroy the glass containers.
Switch the cooling device on by turning the knob (fig. 1 A, page 3) to the right.
After switching on, the cooling device requires approx. 60 s until the compressor starts up.
Caution!
Ensure that the objects placed in the cooling device are suitable for cooling to the selected temperature.
Setting the temperature
You can set the temperature to any level using the knob. The built-in temperature control regulates the temperature as follows:
- min. (left limit) = warmest setting
- max. (right limit) = coldest setting
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 cooling device compartment. The time for which the food can be conserved in this way is usually stated on the package.
Caution!
Do not conserve warm food in the cooling device compartment. Do not place glass containers with liquid in the freezer compartment.
Food which can easily absorb tastes and odours and liquids and products with a high alcohol content should be conserved in airtight containers.
The cooling device compartment is divided in different zones with different temperatures:
- The colder zones are immediately over the base, near the back wall.
- Observe the temperature information and best before date on the food packaging.
Observe the following when using the device: -
Do not re-freeze products which are defrosting or have been defrosted, consume them as soon as possible.
-
Wrap food in aluminium foil or cling film and shut it in a suitable box with a lid. This ensures that aromas, the shape and the freshness are better conserved.
Securing the refrigerator door
You can prevent the refrigerator door from being opened inadvertently.
Put the locking mechanism on the top of the door to position 1
(fig. 3 1, page 4).
Defrosting the cooling device
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.
Caution!
Never use hard or pointed tools to remove ice or to loosen objects which have frozen in place.
To defrost the cooling device, proceed as follows:
Take out the contents of the cooling device.
Place them in another cooling device to keep them cool, if necessary.
Set the knob to 0.
Leave the door open.
Wipe off the water resulting from defrosting or – if present – empty the collecting tray. If your device has a water drain, drain the thawed water off.
Switching off and storing the cooling device
If you do not intend to use the cooling device for a long time, proceed as follows:
Turn the knob to 0.
Disconnect the power cable from the battery or pull the DC cable plug out of the rectifier.
Clean the cooling device (see chapter "Cleaning and maintenance" on page 33).
Leave the lid or door open for to avoid unpleasant odours building up.
Put the lock in the VENT position. This prevents odours from building up.
8 Cleaning and maintenance
Caution!
Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the cooling device.
Caution!
Never use brushes, scouring pads or hard or pointed tools to remove ice or to loosen objects which have frozen in place.
Clean the cooling device regularly as soon as it becomes dirty with a damp cloth.
Make sure that no water drips into the sealings. This can damage the electronics.
Wipe the cooling device dry with a cloth after cleaning.
