Technical description

The hybrid cooler is suitable for portable use. It is equipped with two separate cooling systems. The device features a Peltier cooling system with heat dis-charged by a fan, as well as a compressor cooling system. The cooling sys-tem is non-wearing.
In thermoelectric mode (connection to 12 Vg), it can cool goods down to max. 20 °C below ambient temperature and keep them cool. In compressor mode (connection to 230 V), it can cool goods down to –15 °C and keep them cool.
In compressor mode, you can use the continuously variable thermostat to set the temperature within a range from +12 °C to –15 °C.

Operation

CAUTION! Health hazard!
Food may only be stored in its original packaging or in suitable containers.

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 11).
A few water drops may form inside the cooler if it has been cooling for a lengthy period. This is normal because the mois-ture in the air condenses to water when the temperature in the cooler falls. The cooler is not defective. Wipe it out with a dry cloth if necessary.

Energy saving tips

Choose a well ventilated location which is protected from direct sunlight.
Allow warm food to cool down first before placing it in the cooling device to keep cool.
Do not open the cooling device more often than necessary.
Do not leave the cooling device open for longer than necessary.

Using the cooler

NOTICE! Risk of damage

Do not switch on the device immediately after transporting it. This could damage the cooling system. Leave the device to stand for about 30 minutes after transporting, before you switch it on. This allows the refrigerant to collect again in the compres-sor, and the compressor does not run dry.
Only operate the device from a single energy source. Simulta-neous use of the thermoelectric cooling system and the com-pressor is not permitted.
Ensure that the objects or goods placed in the cooling device are suitable for cooling to the selected temperature.
Ensure that food or liquids in glass containers are not exces-sively refrigerated. Liquids expand when they freeze and can therefore destroy glass containers.
Ensure that your cooler is well ventilated so that any heat cre-ated can dissipate. Otherwise proper functioning cannot be ensured. It is especially important not to cover the air vents.

Place the cooler on a firm base.

Connecting the cooler to 12 V (thermoelectric mode)

NOTE: In thermoelectric mode, the thermostat has no function and the device cannot deep freeze.

Make sure the cable between the cooler and the battery is protected by a fuse (maximum 5 A).
Plug the 12 V connection cable (fig. 1 2, page 2) into the cigarette lighter socket or a 12 V socket in the vehicle.
The cooler starts cooling the interior.
To switch off the cooler:
- Disconnect the plug.
- Wind the cable around the two holders on the back of the device for storage.

NOTE
Disconnect the cooler from the battery when the engine is not run-ning, as otherwise the battery will run down.

Connecting the cooler to 230 V (compressor mode)

Connect the 230 V connection cable (fig. 1 3,) to the 230 V AC mains supply.
Open the lid of the thermostat (fig. 2,3) by pressing down on it.

NOTE: Press down on the lid again to close it.
Turn the thermostat (fig. 2, 3) clockwise to the required position.

NOTE
The further you turn the thermostat towards “MAX”, the lower the refrigerating temperature.

The cooler starts cooling the interior.
To switch off the cooler:

Turn the thermostat (fig. 2,3,) anti-clockwise to “0”.
Disconnect the plug.
Wind the cable around the two holders on the back of the device for storage.

Connecting to vehicle power

NOTE
If you connect the cooling device to the vehicle power, remember that you may have to turn on the ignition to supply it with power.

Setup Guide

Setting up the Mobicool Cool Boxes MB40-DC is easy. Simply remove the cooler from its packaging, and ensure that it is clean and dry before use. To use the cooler, follow these steps:

Place ice packs or loose ice in the bottom of the cooler.
Place your food and drinks in the cooler, using the removable wire basket to keep them organized and easy to access.
Close the lid and secure the locking system.
Place the cooler in a cool, shaded area to maximize its cooling performance.

Cleaning and maintenance

NOTICE! Risk of damage

Never clean the cooler under running water or in dish water.
Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the cooler.

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.

Troubleshooting

Problem	Possible cause	Suggested remedy
Your device is not working (plug is inserted).	There is no voltage flowing from the DC socket (cigarette lighter) in your vehicle.	The ignition must be switched on in most vehicles to supply current to the cigarette lighter.
	No voltage present in the AC voltage socket.	Try using another plug socket.
	The inner fan or the cooling element or the compressor is defective.	This can only be repaired by an authorised repair centre.
When operating from the DC socket (cigarette lighter):	The fuse of the DC plug is dirty. This results in a poor electrical contact.	If the plug of your cooler becomes very warm in the DC socket fitting, either the fitting must be cleaned or the plug has not been assembled correctly.
The ignition is on and the cooler is not working.	The fuse of the DC plug has blown.	Replace the fuse of the DC plug with one of the same rating (fig. 3, 1, page 2).
	The vehicle fuse has blown.	Replace the vehicle’s DC socket fuse (usually 15 A). Please refer to the operating manual of your vehicle.
