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.
