6 Technical description

CoolMatic CB36, CB40 and RHD50 cooling devices are suitable for use with a 12 V or 24 V DC voltage and can therefore also be used for camping or on boats. You can also use the EPS-100W and MPS-35 rectifiers to connect them to a 230 V mains supply.
The cooling device can chill products and keep them cool. CoolMatic CB36 and CB40 devices can also be used to freeze products.
All materials used in the cooling device are compatible for use with foodstuffs. The refrigerant circuit is maintenance-free.
You can use the continuously variable thermostat in the interior of the device to set the desired temperature.
The cooling device has a undervoltage protection mechanism. To protect the battery, the cooling device switches off automatically if the voltage is insufficient. When the voltage is sufficient again, it switches on again.
When used on boats the cooling device can be subjected to a constant inclination of 30°.
CoolMatic CB36 and CB40 devices are equipped with a removable cooling unit that can be mounted separately.

7 Installing and connecting the cooling device

The device is designed for ambient temperatures between 16 °C and 32 °C. In continuous operation, the air humidity may not exceed 90 %. Install the cooling device in a dry, sheltered place (installation dimensions: fig.1to fig.3, page 3). Avoid installing the devices next to heat sources such as heaters, gas ovens, hot water pipes, etc.
The cooling device must be installed so that heated air from the cooling unit can dissipate easily. Therefore make sure there is adequate ventilation. On the CoolMatic CB36, CB40 and RHD50 devices, the cooling unit is removable and can be mounted at a distance of up to 1.5 m (CB36, CB40, RHD50) away from the cooler if space is limited.

7.2 Adapting the decor (only CB36, CB40)

The lids of the devices can be adapted to match the decor of the surroundings.

7.3 Connecting the cooling device

Connecting to a battery
The cooling device can be operated with a 12 V to 24 V DC voltage supply.

NOTICE!

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.4, page 4. Key for fig.4, page 4

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

NOTICE!

Make sure that the polarity is correct.

Connect the red lead to the positive terminal.
➤ Connect the black lead to earth.
➤ 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).

NOTICE!

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

DANGER! 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 230 V from the land, you must install a ground protection circuit breaker between the 230 V mains supply and the
  cooling device. Seek advice from a trained technician.

To operate the cooler on a 230 V or 110–240 V mains supply, use the EPS-100W (230 V) or MPS-35 (110 – 240 V) rectifier.

Operation

NOTE

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 15).

8.1 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 or lid 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.
• Clean the lid seal regularly.

8.2 Using the cooling device

The cooling device conserves fresh foodstuffs. You can conserve frozen foodstuffs
and freeze fresh foodstuffs in the CoolMatic CB36 and CB40 devices.

NOTICE!

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 to the right.

NOTE

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

NOTICE!

Ensure that the objects placed in the cooling device are suitable for cooling to the selected temperature.

Lock

RHD50

To open the cooling device, pull the clip (fig.51, page 4) and open the door.
To lock the cooling device, close the door and press it until the lock engages. CB36/CB40
The lid rests on top and is not locked. 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

NOTE

The cooling capacity can be influenced by

• the ambient temperature,
• the amount of food to be conserved,
• the frequency with which the door/lid 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.

NOTICE!

Do not conserve warm food in the cooling device compartment.
Do not place glass containers with 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 air-tight containers.

The cooling device compartment is divided in different zones with different temperatures:

• The colder zones are immediately over the base.

• 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 in in a suitable box with a lid. This ensures that aromas, the shape and the freshness are better conserved

Defrosting the cooling device (only CB36, CB40)

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.

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 cover open.
➤ Wipe off the defrosted water.

9 Cleaning and maintenance

➤ Occasionally clean the device interior and exterior with a damp cloth.
➤ Make sure that the air inlet and outlet vents on the device are free of any dust and dirt, so that heat can be released and the device is not damaged.
➤ Make sure that no water drips into the sealing. This can damage the electronics.
➤ Wipe the cooling device dry with a cloth after cleaning.

10 Guarantee

The statutory warranty period applies. If the product is defective, please contact the manufacturer’s branch in your country (see the back of the instruction manual for the
ddresses) or your retailer.
For repair and guarantee processing, please include the following documents when
you send in the device:

• A copy of the receipt with purchasing date
• A reason for the claim or description of the fault

11 Disposal

CAUTION!

When disposing of the device, make sure it is not overheated, as the insulating foam was made with flammable gas
➤ Place the packaging material in the appropriate recycling waste bins wherever possible

If you wish to finally dispose of the product, ask your local recycling centre or specialist dealer for details about how to do this in accordance with the applicable disposal regulations.
