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

7.1 Installing 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. 1 to 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

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).

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.

NOTICE!

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".
