STARTING THE REFRIGERATOR
LP Gas Operation
AES will select LP gas operation under
the following conditions:
• No AC (230V) available
• Engine not running (no high current at
12V DC available)
• AC available but too low
• Engine running but DC supply too low
(condition three and four are briefly
described in item Undervoltage Operation
over the page)
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 energised.
After initial installation, servicing, or changing
gas cylinders etc., the gas pipes may contain
some air which 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 igniter is immediately activated and
reignites the gas.
Note: The control electronics and the igniter
must have a DC (battery) supply to operate.
Gas trouble-shooting
If the AES LED (C) is flashing red, the system
was not able to start or continue gas
operation. Set the switch (A) to OFF and
check that there is enough gas in the gas
bottle, that its valve is open and that any
valves in the gas line to the refrigerator are
open.
Push button (A) to "ON" again. After 10 sec.
AES will repeat the ignition sequence. If the
AES LED (C) again starts flashing red after
30 sec., the problem persists (air in the line,
no gas?). Switch (A) briefly off and then on
again. It might be necessary to repeat this
operation 2-3 times if the tubing contains air
(after changing gas bottles, repairs etc.).
If this does not help, you should consult a
service technician.
230V 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.
12V Operation
AES will select the 12V mode of operation
only when the vehicle engine is running
(detected by the alternator connection of the
fridge D+).

MODEL RM4505
The model RM4505 is a 135 litre refrigerator
with a separate 25 litre frozen food
compartment.
This refrigerator is equipped with an
Automatic Energy Selector (AES) which
controls its operation and energy supply.
The system selects the available energy
source in the order: 230V - 12V - LP gas.
No manual operation is necessary for
selecting the energy source.
OPERATING INSTRUCTIONS
The refrigerator is set into operation by
pushing button (A) (main switch). The AES
LED (C) lights green showing that the AES
system is working. Push-button (B) is used
for setting the electronic thermostat. The
thermostat LEDs (D) show the chosen
temperature position. When there is a
demand for refrigeration, AES will connect
the most favourable of the available energy
sources.
Note: 12V must always be available to
supply the electronics.
