LP Gas operation
AES
AES will select LP gas operation under the following
conditions:
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.
• 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.
The system selects the available energy source in the order:
1. 230-240V
2. 12V
3. LP gas
Turn off the AES function if you want the refrigerator to run
on LP gas only.
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!

REGULATING THE TEMPERATURE
Gas troubleshooting
If the Warning indicator lamp (F) is lit, there has been a failure
of gas operation. To troubleshoot, follow these steps:
1. Turn off the refrigerator. (Press the ON/OFF (1) to
“OFF”.)
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.
2. 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.
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.
3. Turn on the refrigerator again. (Press the ON/OFF button
(1) to “ON” .) After 10 sec. AES will repeat the ignition
sequence.
4. Should the warning lamp come on again after approx. 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.
TRAVEL CATCH
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.
Make sure that the travel catch is engaged when the motorhome is on the move.
using the refrigerator
! WARNING
DO NOT store explosive substances in the refrigerator,
such as cigarette lighter gas, gasoline, ether or the like.
230-240V operation
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.
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 as soon as the
vehicle engine is running (detected by the alternator connection
of the fridge D+).
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.
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.
! WARNING
It is not allowed to have a naked flame at a gas filling
station. If you are not sure, that your stop is shorter
than 15 min., you are advised to set the ON/OFF switch
(1) to “OFF”, when stopping at a filling station.
5
Defrosting
Replacing the bulb
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.
To replace the bulb, follow these steps:
1. Remove the lamp cover.
RM4605/RM4805: Push the lamp cover backwards.
3. Replace the cover.

2. Empty the refrigerator.
3. Leave the drip tray under the finned evaporator.
4. Leave the cabinet and freezer door open.
Defrost water runs from the drip tray through a plastic
drain water hose to the outside of the vehicle.
5. When all the frost has melted - dry the interior of the refrigerator with a clean cloth and replace the ice trays.
6. Turn on the refrigerator. Set the thermostat to the coldest position for a few hours and then, reset to the desired
setting.
7. Place the food items back inside.

The heating cable will draw 12V DC
power continuously when in the ON (I)
position. It should be turned off when
a charging source is not available.
TURNING OFF THE REFRIGERATOR
If the refrigerator is not to be used for some time:
1. Turn off the refrigerator. (Press the ON/OFF button (1)
to “OFF”.)
CLEANING THE REFRIGERATOR
2. Shut off any on-board valve in the gas line to 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.
To have the heating
cable on, you position
the switch located beneath the control panel
to I, see Fig. 2.
The heating cable can
be left on continuously
or only used when temperatures require it.
ON
During the summer months of high temperatures and humidity, the metal frame between the
freezer and fresh food compartments may have
water droplets forming. This refrigerator comes
standard with a 12V DC heating cable that will
evaporate the water droplets when they form.
OFF
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.
2. Replace the old bulb with an appliance bulb of the same
wattage (12V, max 10W).
3. Pull out the plug from the wall socket.
4. Empty the refrigerator. Defrost and clean it as described
earlier. Leave the doors of the refrigerator and frozen food
compartment ajar.
Km
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!

Product care - some useful hints
MAINTENANCE
Make sure that:
• Defrosting is carried out periodically.
• The refrigerator is clean and dry with the door left open
when it is not to be used for some time.
• Liquids or items with a strong odour are well packed.
• The ventilation openings are unobstructed.
• The doors are secured by means of the travel catch when the
motorhome is on the move.
• This appliance must be serviced by an authorised person. We
recommend that an authorised service technician checks the
refrigerator once a year.
• The “Installation and operating instructions manual” should
always be available.
• Ensure that the gas safety shut-off valve is working properly.
• Make sure that the ventilation openings are unobstructed.
• See to it that the burner is clean and free from combustible
material.
• All connections in the LP gas system should be checked for
gas leaks. Connections can be tested for leaks using a soap
solution. Do not use a naked flame! If there is any suspicion of damage, call for an authorised service technician.
Troubleshooting
If the refrigerator fails to work
Before calling an authorised service technician:
SERVICE AND SPARE PARTS
• Ensure that the instructions in this manual have been followed.
• Check to make sure that the refrigerator is not tilted excessiveley.
• Verify that the LEDs on the control panel are lit when the
ON/OFF button (1) is turned on. (12V must be available.)
• Check the fuses on the circuit board which is located under
the cover on the back of the refrigerator.
• If the mains voltage are connected but the refrigerator stays
in gas operation -> is the refrigerator correctly connected and
is the fuse (230-240V) intact?
• If the refrigerator does not operate in DC mode when
the engine is running -> is the alternator (D+) connection
made correctly?
• If the Warning indicator lamp (F) lights up -> see ”Gas
troubleshooting” for further information.
Service and spare parts are obtainable from your dealer or
Dometic - consult the telephone directory.
INSTALLATION INSTRUCTIONS
The refrigerator is intended for installation in a motorhome,
and the information relates to this application. A correct installation is important for correct operation of the appliance.
The refrigerator must be installed on a solid floor and must
be level. With the vehicle carefully levelled, the refrigerator
should be level both ways in the freezer compartment.
Free air circulation over the fins of the cooling unit is essential.
The refrigerator is not cold enough
VENTILATION OF THE UNIT
If the refrigerator is not cold enough it may be because:
Ventilation grilles
• The ventilation is inadequate owing to reduced area of the
ventilation passages (partial blockage of grilles from wire
mesh etc.).
• The evaporator is frosted up.
• The temperature control setting is incorrect.
• The gas pressure is incorrect - check the pressure regulator at
the gas container.
• The ambient temperature is too high.
• Too much food is loaded at one time.
• The door is not properly closed or the magnetic sealing strip
is defective.
We recommend fitting the Dometic ventilation system, which
is specially developed by Dometic for this purpose. The
Dometic ventilation grilles permit inspection and small repairs
to be carried out without the necessity of removing the refrigerator from the recess.
If there is no outer grille at floor level where leaking gas can
escape, a 40 mm hole to the outside should be made in the
floor of the recess to drain any unburned gas to the outside. Fit
the hole with wire mesh and an angled plate to protect it from
stones, mud etc.
Side ventilation
If the refrigerator still does not work properly, call an authorised service technician.
The refrigerator unit is ventilated via two openings in the wall
of the motorhome. Fresh air enters through the lower opening
and warm air is discharged through the upper one.
The lower opening should be located at floor level to allow
any leaking gas to escape to the outside. The upper ventilation
opening should be located above the condenser, as high as possible, to ensure good ventilation.
! WARNING
The sealed cooling system must not be opened, since it
contains corroding chemicals under high pressure.
Roof ventilation
The ventilation of the cooling unit can also be done via one
opening in the wall of the motorhome and one on the roof for
the roof vent.
Fresh air enters through the lower opening and warm air is
discharged through the roof vent. The lower opening should be
located at floor level to allow any leaking gas to escape to the
outside.
7
Removal of flue gases
Clearances
The ventilation passage at the rear of the recess, between the
outer wall of the vehicle and the refrigerator must be sealed
off against the living space, so cold draughts are excluded
(winter camping) and no flue gases can penetrate into the
motorhome.
Minimum clearances (mm) to
combustible materials
RM2355
The flue gases are dispersed from the ventilation passage using
the Dometic flueing system. The top, bottom and sides of the
ventilation passage should be insulated to prevent condensation and cold draughts. The ventillation passage walls must be
constructed of a non combustable material.

BUILDING-IN
Securing the refrigerator
The refrigerator must not be exposed to radiated heat from hot
objects. Excessive heat irradiation impairs performance and
leads to increased energy consumption. For this reason the refrigerator should be installed if possible not at the entrance side
of the vehicle - normally orientated south and often with an
awning which would impair the dispersion of heat and combustion gases from the ventilation openings.
For the best cooling performance, when installing the refrigerator model(s):
• RM2355: The installer must block the space between the
storage cabinet and the top of the refrigerator.
• RM2455/RM2555/RM4605 & RM4805: The installer must
block any space between the counter, storage area or ceiling
and top of the refrigerator greater than 40 mm.
It is not a good practice to install the refrigerator so that the
vent openings are covered by the vehicle’s entrance door when
this is set open. This would reduce the ventilation airflow to the
cooling unit and reduce refrigeration performance.
Otherwise the heat will become trapped in this space, making
the top of the refrigerator hot, thus reducing the efficiency of
the unit.
After the refrigerator is put in place, insuring a combustion
seal at the front frame, the refrigerator is to be secured in the
enclosure with screws. (These screws are not included.)
Failure to follow the sequence in securing the refrigerator in
enclosure can cause leakage between the frame and cabinet.
The refrigerator has to be installed in a substantial enclosure
and must be level. For information about dimensions, see
”Technical data”.
The bottom of the enclosure must be horizontal and even so
that the refrigerator can be easily pushed into place. It must be
sturdy enough to carry the weight of the refrigerator.
The five screws should be installed in the following order:
A length of sealing strip is
applied to the rear surface
of the front frame for this
purpose, see Fig. 8 / Fig. 9.
Fig. 8
1. Four screws installed through the front
frame.
2. One screw installed in rear base.
Make sure that there is a
complete seal between the
front frame of the refrigerator and top, sides and
bottom of the enclosure.

Push the refrigerator into
the recess until the sealing
strip on the flange seals
against the front of the
recess, so that the cooling
unit is completely sealed
off against the interior of
the motorhome.
Note! Be careful not to
damage the sealing strip
when the refrigerator is
put in place.

REPOSITIONING THE HINGES
• RM2355/RM2455/RM2555
The refrigerator is equipped with reversible doors. A special
door reversing kit must be used to reverse the doors. This kit is
delivered with RM2355 but must be bought separately for
RM2455 and RM2555 (part number 2932750-13/2) as well as
for RM4605 and RM4805 (part number 2932750-11 (black)
and 2932750-08 (brown)). For further information, please
contact your dealer.

• RM4605/RM4805
Maximum length of 8 meters from refrigerator to the battery.
10 mm2 cross-section low voltage multi strand cable.
Cable lengths > 8 meters will require a larger cross-sectional
cable.
Mounting the door panel
Door panels for RM2355 must be supplied by
the manufacturer. This enables the manufacturer
to match the door panel with the rest of the cabinetry inside the motor home or caravan.
Before starting the mounting work, read the
instructions thoroughly. Check that the panel
dimensions are in compliance with those given in
the following table:
connection marked “Connect to permanent 12 volt
DC House Battery” (RM2355/RM2455/RM2555) or
“12V DC House” (RM4605/RM4805)
This connection supplies the AES refrigerator control system
and must not be interrupted at any time whilst using the refrigerator on 240 volt, gas, and 12 volt. This is a permanent 12 volt
connection.
The (+12V) and (-) poles have to be connected directly to the
permanent 12V DC house battery.
Dimensions (mm)
(Thickness max 4 mm)
Do not use the chassis for the return lead.
The 12V supply must not be connected to a voltage controller
or similar device as the AES control system itself monitors the
DC voltage.
The +12V must be permanently attached and must not be cut
out when the ignition key is turned off. All connections should
be screwed or soldered to keep voltage drop to a minimum.

We recommend that the panel is mounted before
the refrigerator is installed in the enclosure. The
lower decoration strip and parts bag are taped
inside the door.
Cross-sections
The wires connected to this terminal must have a minimum
cross-section area of 1.5 mm2.
To mount the door panel, follow these steps:
D+ connection
The connection D+ (alternator) has to be connected to the corresponding outlet of the vehicles electrical system - either a
12V or a 24V DC alternator. The D+ connection accepts
24V. Please note that the refrigerator accepts 12V only. Do not
connect the refrigerator to 24V!
1. Slide the panel from the bottom of the door
into the grooves on the vertical edges of the
door.
2. Push the panel upwards. Take the two plastic
panel stops from the parts bag and put them
in the two holes at the lower door frame.
This connection provides a signal to the refrigerators AES
control system informing the control system when the vehicle
engine is running.
3. Put the decoration strip across the door and
fasten it with three screws from the parts
bag.
The AES refrigerator can not select 12V as the energy source
unless the vehicle engine is running.
Cross-sections
The D+ (alternator) is a signal cable and therefore 1-1.5 mm2 is
sufficient.
