LP gas-only operation can be selected by pressing the AES/
GAS button (2) until LED (B) comes on; the AES function is
then turned off and LED (A) goes out. The Temperature selector button (3) is used to set the electronic thermostat. The LEDs
(E) show the value set on the thermostat.
LP GAS OPERATION
AES will select LP gas operation under the following
conditions:
No AC (230-240V) available•
Engine not running (no high current at 12V DC available)•
When the system chooses LP gas operation, the flame failure
device is automatically opened, allowing the gas to flow to the
burner. At the same time, the electronic igniter is energized.
After initial installation, servicing, or changing gas cylinders
etc., the gas pipes may contain some air that should be allowed
to escape by briefly turning on the refrigerator or other appliances. This will ensure that the flame lights immediately.
If the flame goes out (by gust of wind etc.), the reigniter will
automatically relight the flame.
The control electronics and the igniter must have
12V DC (battery) supply to operate!
GAS TROUBLESHOOTING
If the Warning indicator lamp (F) is lit, there has been a failure
of gas operation.
To troubleshoot, follow these steps:
Turn off the refrigerator. (Press the ON/OFF (1. 1)
to “OFF”.)
Check that there is enough gas in the gas bottle, 2.
that its valve is open and that any valves in the gas
line to the refrigerator are open.
Turn on the refrigerator again. (Press the ON/3.
OFF button (1) to “ON” .) After 10 sec. AES will
repeat the ignition sequence.
Should the warning lamp come on again after ap-4.
prox. 6 minutes, the failure is still present. Repeat
the procedure once more. If this does not help,
contact an authorised service provider in your
area.
ABNORMAL OPERATION
Any of the following are considered to be abnormal operation
and may require servicing:
Yellow tipping of the burner flame.•
Sooting up area surrounding burner.•
Burner not igniting properly.•
Burner failing to remain alight.•
In case the appliance fails to operate correctly, contact an authorised Dometic Service Centre.
230-240V OPERATION
When a mains connection is available, AES will select this.
Please note, that even being in AC mode, 12V DC is necessary
for the internal supply of the electronics.
OPERATING INSTRUCTIONS
CONTROL PANEL
AES
The refrigerator is equipped with an Automatic Energy
Selector (AES) controlling the operation and energy supply.
NOTE! 12V must always be available to supply the
electronics.
The system selects the available energy source in the order:
230-240V1.
12V 2.
LP gas3.
Turn off the AES function if you want the refrigerator to run
on LP gas only.
STARTING THE REFRIGERATOR
Press the ON/OFF button (1. 1). The refrigerator
starts in the mode it was in when it was turned off.
Press the AES/GAS button (2. 2) and LED (A) or (B)
comes on. Select AES or LP gas only by pressing
the AES/GAS button (2) once if necessary.
If a 230V-240V mains supply is available:3.
AES selects this as the energy source and LEDs •
(A) and (C) come on.
When the vehicle’s engine is running, AES •
selects 12V operation and LEDs (A) and (D) are
illuminated unless LP gas only operation has
been selected manually.
If neither mains nor a 12V battery supply are
available:
AES selects LP gas operation and LEDs (• A) and
(B) come on.

12V OPERATION
AES will select the 12V mode of operation as soon as the
vehicle engine is running (detected by the alternator connection
of the fridge D+).
If the 12V DC goes down below 9V DC, the system will shut
down completely.
SWITCHING BETWEEN ENERGY SOURCES
When switching from one energy source to another, there are
some delays implemented in the AES system. The 15 min.
delay between switching off the engine and starting gas mode
is intended to delay the starting of gas mode e.g. when stopping
at a filling station.
REGULATING THE TEMPERATURE
The position number refers to Fig.1.
It will take a few hours for the refrigerator to reach normal
operating temperature. So we suggest you start it well in advance of a trip and if possible store it with precooled foodstuffs.
The temperature of the refrigerator main compartment is set
for all three sources of energy, by means of the Temperature
selector button (3). After turning on the refrigerator the system
automatically chooses the mid-position. With some experience
you will soon find a suitable setting, bigger circles indicate
lower temperatures. This normally does not need resetting
because the same thermostat controls the main compartment
temperature for any of the three sources of energy.
TRAVEL CATCH
Make sure that the travel catch is engaged when the motorhome is on the move.
USING THE REFRIGERATOR
FOOD STORAGE
Always keep food in closed containers. Never put hot food in
the refrigerator; allow it to cool first.
The frozen food compartment is intended for the storage of frozen food and for making ice. Most kinds of frozen food can be
stored in the frozen food compartment for about a month. This
period of time may vary, however, and it is important to follow
the instructions on the individual packages.
ICE MAKING
Fill the ice tray to just below the brim with drinking water and
place them on the bottom of the freezer compartment. Ice will
be made more rapidly if the thermostat is set at its highest position (biggest circle), but be sure to move the thermostat back
to normal setting when the ice is formed; the refrigerator might
otherwise become too cold.
DEFROSTING
Frost will gradually accumulate on the refrigerating surfaces.
Each time the door is opened some of the cold air in the refrigerator spills out and is replaced by warm moist room air. As
this air is cooled, the moisture is deposited onto the evaporator coils or other cold surfaces inside the refrigerator and can
cause frost build-up.
It is important that you do not leave the unit’s door open any
longer than necessary. This will reduce frost formation and
increase the efficiency of your refrigerator.
The frost must not be allowed to grow too thick as it acts as an
insulator and adversely affects refrigerator performance. Check
the formation of frost regularly every week and when it gets
about 3 mm thick, defrost the refrigerator.
Do not try to accelerate defrosting by using any
kind of heating appliance, as this might damage the
plastic surfaces of the refrigerator. Neither should
any sharp objects be used to scrape off the ice.
To defrost the refrigerator, follow these steps:
Turn off the refrigerator. (Press the ON/OFF but-1.
ton (1) to ”OFF”.)
Empty the refrigerator. 2.
Leave the drip tray under the finned evaporator.3.
Leave the cabinet and freezer door open. 4.
Defrost water runs from the drip tray through
a plastic drain water hose to the outside of the
vehicle.
When all the frost has melted - dry the interior of 5.
the refrigerator with a clean cloth and replace the
ice trays.
Turn on the refrigerator. Set the thermostat to the 6.
coldest position for a few hours and then, reset to
the desired setting.
Place the food items back inside. 7.
CLEANING THE REFRIGERATOR
Clean the inside of the refrigerator regularly to keep it fresh
and hygienic.
Never use detergents, scouring powder, strongly
scented products or wax polish to clean the interior
of the refrigerator as they may damage the surfaces
and leave a strong odour.
Soak a cloth in a solution consisting of a teaspoon of bicarbonate of soda to half a litre of warm water. Wring out the cloth
and use it to clean the interior of the refrigerator and its fittings.
The exterior of the refrigerator should be wiped clean now and
then, using a damp cloth and a small quantity of detergent. But
not the door gasket, which should only be cleaned with soap
and water and then thoroughly dried.
The cooling unit behind the refrigerator should be cleaned with
a brush from time to time. Make sure that the refrigerator is
switched off when doing this!
