RUA6408X, RUA8408X Intended use
5 Intended use
The refrigerator is designed for installation in caravans or motorhomes. It is only
suitable for cooling, freezing and storing foodstuffs. The refrigerator is not intended
for the proper storage of medicine.
CAUTION! Health hazard!
!
The refrigerator is designed to be operated on a DC power supply and an AC socket
and can be powered by liquid universal LPG gas. The refrigerator may not be run on
natural gas or city gas.
I
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
consumer unit to protect the battery. Ask your vehicle manufacturer for
more information.
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.
For ignition, the device does three attempts to ignite the flame for a period of
30 seconds at two minutes interval (if flame does not ignite, see chapter “Troubleshooting” on page 38).
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 refrigerator has a manual power mode selection and an automatic operating
mode which selects the most economical power mode connected.

NOTICE!
•
A
I
Make sure that you only put items in the refrigerator which may be
kept at the selected temperature.
•
Make sure that items in the refrigerator do not block the openings of
the cooling ventilation areas in the main compartment
•
Foodstuff may only be stored in its original packaging or in suitable
containers.
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 (e.g. when the vehicle is exposed to
direct sunlight)
– 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.
•
Approximately one hour after switching on, the freezer compartment of the refrigerator should be cold. The refrigerator reaches its
operating temperature after a few hours.
•
Battery management systems switch off the power supply to the
refrigerator as soon as the vehicle engine is switched off for a longer
period of time. The refrigerator requires a constant DC power supply
to operate. If your vehicle has a battery management system, deactivate it.

7.1 Tips for using the refrigerator optimally
When the temperature in the interior of the refrigerator exceeds +4 °C, the shelf life
of goods that spoil quickly cannot be guaranteed. To attain an optimal cooling
capacity in the interior of the refrigerator, observe the following information:
•
Do not store goods in the refrigerator for the first 12 hours of operation.
•
Protect the interior of the vehicle from warming up excessively (e.g. sunshades in
the windows, air conditioner).
•
Protect the refrigerator from direct sunlight (e.g. sunshades in the windows).
•
Voltage fluctuations can have a negative effective on the cooling capacity. Check
the temperature in the interior of the refrigerator regularly
–when using DC power supply during the journey
– when using AC power supply at the site of use
7.2 Energy saving tips
•
Choose a well ventilated location which is protected from direct sunlight.
•
Allow warm food to cool down first before keeping it cool in the refrigerator.
•
Do not open the refrigerator more often than necessary.
•
Do not leave the doors open for longer than necessary.
•
Defrost your refrigerator as soon as a layer of ice forms.
•
Avoid unnecessarily low temperature settings.
•
Arrange the food in the refrigerator so that air can circulate inside.
•
Leave a distance of at least 10 mm between the contents and ventilation openings on the vent cover.
7.3 Switching on the refrigerator
➤ Press and hold the control knob for more than 3 seconds.

➤ Put a cloth in the freezer compartment and the refrigerator to absorb any excess
water.
➤ Leave the doors open.
✓ The condensate drains off through a hose at the back of the refrigerator and is
routed outside the vehicle.
Never use mechanical tools to remove ice or to loosen objects stuck to
the device.
NOTE
•
The refrigerator compartment has a cyclic defrost system, which can
prevent excessive frost forming on the evaporator fins. However, if
the refrigerator is used for extended pe rio ds i n hi gh humidity and/or
high ambient temperature conditions, frost may build up on the
evaporator fins. In this case, you should defrost the refrigerator.
•
The freezer compartment will require periodic defrosting. If the frost
layer is higher than 3 mm, defrost the freezer compartment.
➤ Wipe both compartments dry with a cloth.
