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 butane/propane gas. For DC operation, the vehicle battery or a solar
system built on the vehicle can be used. For AC and gas operation, the thermostatic
control ensures that the refrigerator temperature is kept constant and as little power
as possible is consumed.

7.1 Energy saving tips
•Allow hot food to cool down first before you place it into the refrigerator.
•Do not open the refrigerator more often than necessary.
•Do not leave the door open for longer than necessary.
•Arrange the food in the refrigerator so that air can circulate inside.
•Leave a distance of about 10 mm between the contents and secondary evapora-
tor.
NOTICE!
•Make sure that you only put items in the refrigerator which may be
kept at the selected temperature.
•Food may only be stored in its original packaging or in suitable con-
tainers.
NOTE
•Before starting your new refrigerator for the first time, you should
clean it inside and outside with a damp cloth for hygienic reasons.
•The cooling performance can be affected by:
– The ambient temperature
– The amount of food to be conserved
– How often you open the door
•When using the refrigerator for the first time, there may be a mild
odour which will disappear after a few hours. Air the living space
well.
•Park the vehicle so that it is level, especially when starting up and
filling the refrigerator before setting off on a journey.
•The refrigerator unit operates silently.
•Approximately one hour after switching on, the freezer compart-
ment of the refrigerator should be cold. The refrigerator reaches its
operating temperature after a few hours.
•RML9431/9435 only: Battery management systems switch off
the power supply to the refrigerator as soon as the vehicle engine is
switched off for longer than 30 minutes. The refrigerator requires a
constant DC power supply to operate. If your vehicle has a battery
management system, deactivate it.
