5 Intended use

The refrigerator is designed for installation in caravans or motorhomes. It is only suit-

able for cooling, freezing and storing foodstuffs. The refrigerator is not intended for

the proper storage of medicine.

6 Technical description

6.1 Description

The refrigerator is an absorption refrigerator. The refrigerator is designed to operate

with different types of power and can be run on an AC power supply, a DC power

supply or with liquefied universal LPG gas. For DC operation, the vehicle battery can

be used. The thermostatic control ensures that the refrigerator temperature is kept

constant and as little power as possible is consumed.

The refrigerator is equipped with an automatic safety device which automatically

terminates the gas supply to the burner approximately 30 seconds after the flame

goes out and remains out.

The RMDX21 refrigerator has manual power mode selection.

The RMDX25 refrigerator has an automatic operating mode which selects the most

economical power mode connected.

CAUTION! Health hazard!

Please check if the cooling capacity of the refrigerator is suitable for

storing the food you wish to cool.

NOTE

To safely operate 12 V consumer units in the caravan, it must be ensured

that the towing vehicle provides sufficient voltage. On some vehicles,

the battery management system may automatically switch off the con-

sumer unit to protect the battery. Ask your vehicle manufacturer for

more information.
