OPERATING INSTRUCTIONS
CONTROLS
The refrigerator can be run on either 120V AC, 12V DC or
LP gas. Changing between these modes of operation is
carried out by means of the controls of the control panel
shown in fig 3.
Two rocker switches are used to select the electric power
supply, one for 120V AC (B) and one for 12V DC (A).
Refrigerator temperature is controlled by a thermostat (C)
when the unit runs on 120V AC. The gas supply is turned
on/off by means of the knob (D). When lighting the gas,
press in the knob as explained further on.
The refrigerator is fitted with a safety device which automatically shuts off the supply of gas if the flame goes out.
In model RM 4180 a manual piezo-eletric igniter is used.
When the button (F) is pressed, sparks are generated at
the burner.
Inside the refrigerator at bottom left is a sight glass for the
burner. A blue light can be seen through it when the flame
is alight (RM 4180).
In model RM 4181, the gas flame is electronically lit,
monitored and relit if necessary. For this the toggle switch
(E) should be on during gas operation.
An indicator lamp in the switch flashes when the automatic igniter attempts to light the burner. Otherwise this lamp
is off.
STARTING THE REFRIGERATOR
Only use one source of energy at a time.
The position numbers refer to fig. 3., pg. 10
LP Gas operation
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.
To start gas operation:
1. Open the shut-off valve of the gas bottle (check that
there is enough gas). Open any on-board shut-off
valve.
2. Check that the switches for mains and 12 V operation
are off.
If you have Model RM 4181 proceed as follows:
3. Turn on the gas supply by pressing the (D) knob and
turning it to the position .
4. Set the thermostat knob (E) to the highest position.
5. Depress switch (F). The switch now starts to flash, indi-
cating that sparks are being generated at the burner.
6. Keep the (D) button pressed for a further 10 to 15
seconds to active the flame failure device, then release
it.
7. When the flame lights, the sparking stops automatically
and the switch stops flashing.
If you have Model RM 4180 proceed as follows:
3. Turn on the gas supply by pressing the gas control (D)
and turning it into position .
4. Set the thermostat knob (E) to the highest position.
5. Keeping the flame failure device (D) pressed, activate
the igniter (F) several times until the flame lights.
6. Keep the knob (D) depressed for a further 10-15
seconds.
7. Release the knob and again check that the flame stays
alight.
The flame can be observed in a viewing glass inside the
refrigerator at the bottom left (RM 4180).
To terminate gas operation, turn knob (D) to l and
(when applicable) set switch (F) to 0.
120V AC Operation
Turn off gas or 12V operation when applicable.
Turn the knob (C) of the thermostat to its highest
(coldest) position.
Set switch (B) to position I. The switch will light up
green when the power supply is connected
12V DC Operation
Only operate your refrigerator on 12V DC when the engine of the vehicle is running - otherwise your battery will
soon be discharged.
If applicable, turn off the gas operation.
Set the 12V rocker switch (A) to I. The switch will
light up red when the power supply is connected.
WINTER OPERATION
Please check that the ventilation grilles or the flue outlet
are not blocked by snow, leaves etc.
DOMETIC ventilation grilles L100/L200 (fig 2), can be fit-
ted with winter covers, to protect the cooling unit against
cold air. The covers may be fitted when the outside temperature is below approx. 10°C and should be fitted when
the temperature is below the
freezing point.
We suggest that you fit the winter covers also in the case
that the vehicle is laid up during the winter months.
REGULATING THE TEMPERATURE
The position number refers to fig. 3.
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.
On 120V operation the refrigerator is controlled by a thermostat and the thermostat knob (C) should be set at 3-5.
If a lower (colder) temperature is desired, set the thermostat to a higher figure.
On 12 V operation the refrigerator works continuously.
On LP gas operation the refrigerator temperature is regulated by the rotary knob (D), which should be set at 3-5. If
a lower (colder) temperature is desired, set the thermostat to a higher figure.

CAUTION
TRAVEL CATCH
Make sure that the travel catch is engaged when the
vehicle is on the move, (fig 1).
The travel catch at the top of the door can be set in two
different positions. In one position the door is held tightly
shut. In the other position the door is secured ajar so that
the refrigerator can be aired when not in use.
FOOD STORAGE
Always keep food in closed containers. Never put hot
food in the refrigerator; allow it to cool first.
Never keep items in the refrigerator which might give
off flammable gases.
Avoid using large dishes and do not stack food or food
containers too closely as this interferes with the circulation of cold air within the cabinet.
If possible, start the refrigerator on gas or AC the day
before it is to be used, to allow time for the interior to be
cooled. It is then preferable to load the refrigerator with
food which has been precooled.
Before moving the vehicle, make sure that all containers
are tightly covered to avoid spills. If required, crumpled
paper may be packed between bottles and other items to
prevent shifting while traveling.
Engage the travel catch at the top of the front corner of
the door before moving the vehicle.
ICE MAKING
It is practical to make ice during the night - then the refrigerator is less demanded and the cooling unit has more
reserves. Fill the ice tray to just below the brim with drinking water and place it on the freezer shelf.
To speed up the ice making, one can spill one or two spoonfuls ofwater on the freezer shelf to improve the contact
to the ice tray.
DEFROSTING
Frost will gradually accumulate on the refrigerating surfaces. It 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 defrost the `fridge, turn it off and remove the ice
tray and all food items.
Warning: normally the temperature of items of foods
would rise unduly during defrosting and so they should be
consumed within 24 h or discarded.The defrost water
runs from a collector channel to a receptacle at the rear
of the refrigerator where it evaporates. When the ice has
melted, wipe the refrigerator dry and restart it. Place the
food items back inside but wait until the refrigerator is
cold before making ice cubes.
DO NOT use a hot air blower. Permanent damage could result from warping the metal or plastic parts. DO NOT use a knife or an ice pick, or
other sharp tools to remove frost from the freezer shelf.
CLEANING THE REFRIGERATOR
Clean the inside of the refrigerator regularly to keep it
fresh and hygienic.
To clean the interior of the refrigerator, use lukewarm
water and a mild dishwashing detergent. Use only warm
water to clean the finned evaporator, gaskets, ice trays
and shelves. NEVER use strong chemicals or abrasives
to clean these parts as the protective surfaces will be
damaged. It is important to always keep the refrigerator
clean.
The exterior of the refrigerator should be wiped clean now
and again, 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.
TURNING OFF THE REFRIGERATOR
If the refrigerator is not to be used for some time:
1. Set any switches to 0.
2. Set the gas valve (D) to l.
3. Shut off any on-board valve in the gas line to the
refrigerator.
4. Empty the refrigerator. Defrost and clean it as
described earlier. Leave the door of the refrigerator
ajar. Use the travel catch to hold in this position.
5. When the vehicle is laid up for a long period of time
(e.g. during the winter months), we suggest fitting the
winter covers ,fig. 2, onto the vent grills.
IF THE `FRIDGE FAILS TO WORK
Check the following points before calling a service technician:
1. That the STARTING THE REFRIGERATOR instructions have been followed.
2. The refrigerator is level.
3. If it is possible to start the refrigerator on any of the
connected sources of energy.
4. If the refrigerator fails to work on gas, check:
That the gas bottle is not empty.
That all LP-gas valves are open.
5. If the refrigerator fails to work on 12 V, check:
That the 12 V supply is connected to the
refrigerator.
That the fuse on the 12 V supply is intact.
That the 12 V switch is on.
6. If the refrigerator fails to work on 120V, check:
That the 120V supply is connected to the
refrigerator.
That the fuse is intact.
If the refrigerator is not cold enough it may be
because:
1. The ventilation is inadequate owing to reduced area of
the ventilation passages (partial blockage of grilles
from wire mesh etc).
2. The evaporator is frosted up.
3. The temperature control setting is incorrect.
4. The gas pressure is incorrect - check the pressure
regulator at the gas container.
5. The ambient temperature is too high.
