INSTALLING REFRIGERATOR IN
ENCLOSURE
NOTE: DO NOT install the appliance directly on
carpeting. Carpeting must be removed or
protectedbya metalor wood panelbeneath
the appliance, which extends at least full
width and depth of the appliance.
NOTE: A wood strip must be in place across the upper
openingof the enclosure.Thetop frame of the refrigera-
tor will be anchored to the wood strip with screws.
See FIG. 3 page 3.
The refrigerator must be installed in a substantial enclo-
sure and must be level. When installing the refrigerator
in the enclosure, all areas within the recess in which the
refrigerator is installed must be sealed.
Make sure that there is a complete seal between the
front frame of the refrigerator and the top, sides and
bottom of the enclosure. A length of sealing strip is ap-
plied to the rear surface of the front frame for this pur-
pose, see FIG. 4. The sealing should provide a com-
pleteisolationoftheappliance’scombustionsystemfrom
the vehicle interior.
NOTE: Be careful not to damage the sealing strip when
the refrigerator is put in place.
Securing the Refrigerator
After the refrigerator is put in place, (ensuring a com-
bustion seal at the front frame), the refrigerator is to be
secured in the enclosure with six screws (not included).
The screws have to be installed in the following order:
STEP1: Two screws installed through the front base,
which includes the lower front strip installation.
The refrigerator is provided with a lower front strip
(shipped as a loose part).The front strip is to be attached
after the refrigerator is set into the cut-out opening.
1. Install the lower front strip by sliding it under the
bottom hinge plate, as shown in FIG. 5. The hinge
plate can be on the right or left side depending on
the door swing.

STEP 3: Two screws installed in the rear base.
See FIG. 8.
Failuretofollowthesequenceinsecuringtherefrigerator
in the enclosure can cause leakage between the frame
and cabinet. Any space between the counter, storage
area or ceiling and top of the refrigerator greater than
40 mm should be blocked. The heat produced at the
rearof the refrigeratorwill become trappedin this space,
making the top of the refrigerator hot and reduce the
efficiency of the refrigerator.
LP GAS CONNECTION
Therefrigerator is designedfor operation onLP-gas, the
pressure of which must be 2,7 kPa for Propane.
Check that this is stated on the data plate.
The refrigerator is not designed for operation on
town gas or natural gas.
Hook up to the gas supply line is accomplished at the
manual gas valve, which is furnished with a ISO 7/1 -Rp
1/8 internal pipe thread connection. All completed con-
nections should be checked for leaks with soapy water.
FIG. 7

FIG. 8
DO NOT use a flame to check for gas leaks.
The gas supply system must incorporate an approved
gas pressure regulator to maintain a supply pressure of
2,75 kPa .
Whentesting thegas supplysystem attest pressuresin
excessof1/2psi,therefrigeratoranditsindividualshutoff
valve must be disconnected from the gas supply piping
system.
When testing the gas supply system at pressures less
than or equal to 1/2 psi, the appliance must be isolated
from the gas supply piping system by closing its indi-
vidual manual shutoff valve.
In case detailed instructions on the installation and con-
nectiontothe gassupplyarerequired,contactyourdealer
or distributor.
TESTING LP GAS SAFETY SHUTOFF
The gas safety shutoff must be tested after the re-
frigerator is connected to the LP gas supply.
To test the gas safety shutoff, proceed as follows:
1. Start the refrigerator according to the instructions for
LP Gas Operation. See section Operating Instruc-
tions.
2. Check that the gas flame is lit. This can be observed
on the flame indicator E. The red indicator is in the
green field, (ON).
3. Close the gas valve by turning the knob Aback to
“OFF” position.
4. Wait for one minute.
5. Remove protection cover (see FIG. 1). Open the gas
valve by turning knob Ato position “GAS” without
pushing the buttons Cand D.Apply a non-corrosive
commercialbubblesolutionto the burner jet.Becare-
ful not to damage the burner jet.
6. Nobubblesshouldappearattheopening oftheburner

ELECTRICAL CONNECTION
230-240 Volts AC Connection
Theelectrical installationmust becarried out in a proper
anddurablemanner,takingintoaccountallrelevantregu-
lations and codes of practice.
Check that the voltage stated on the data plate is the
same as the mains voltage in use (230-240V).
For mains voltage operation, it is important that the
circuit to and in the caravan is effectively earthed.
Therefrigerator is equipped with a three-prong (ground-
ing) plug for your protection against shock hazards and
shouldbepluggeddirectly into aproperlygroundedthree-
prongreceptacle.DO NOTcutor remove the grounding
prongfrom this plug.The free length of the cord is 1.8 m
and therefore recommended that the receptacle be lo-
cated to the left side of the refrigerator (viewed from the
rear) and approximately 150 mm from the floor. (See
FIG. 9). This allows easy access through the vent door.
The cord should be routed to avoid direct contact with
the burner cover, flue cover or any other components
that could damage the cord insulation.
DO NOT use the chassis or vehicle frame as one of the
conductors. Connect two wires at the refrigerator and
route to the 12 V DC supply.
The refrigerator will draw 15 amps at 12 volt DC.
MAXIMUM TOTAL CONDUCTOR WIRE LENGTH
(in metre)
The connections must be clean, tight and free from cor-
rosion. If not, a resulting voltage drop will cause a de-
creased cooling capacity.
12 Volts DC Connection
The connection is made to the terminal block marked
“12voltsDCheater”, located at the bottomleft corner on
the back of the refrigerator cabinet. (See FIG. 1).
Therefrigerator must be connected to the battery circuit
withtwowiresofadequatecapacitytoavoidvoltagedrop.
The wire gauge should be chosen with consideration to
the wire length in accordance with the table below.
To ensure safe operation, the positive lead must be fit-
ted with a fuse rated at 20 amps.
Correct polarity must be observed when connecting to
the 12 V DC supply.

tery in a very short time. The installation of a 12-
volt DC operated refrigerator requires a relay to
be installed on the tow vehicle or in the cara-
van. The relay will automatically shut off the 12
volt DC power to the refrigerator when the igni-
tion is turned off. (See FIG. below).

OPERATING INSTRUCTIONS
NOTE: After changing an LP tank, or after a long shut-
off period, the gas line is likely to be filled with air. You
mayhave to repeat the lighting procedure several times
to purge the air out of the gas lines.
IMPORTANCE OF LEVELING A
REFRIGERATOR
In an absorption refrigerator system, ammonia is lique-
fied in the finned condenser coil at the top rear of the
refrigerator. The liquid ammonia then flows into the
evaporator (inside the freezer section) and is exposed
to a circulating flow of hydrogen gas, which causes the
ammonia to evaporate, creating a cold condition in the
freezer.
When starting this refrigerator for the very first time, the
cooling cycle may require up to four hours of running
time before the cooling unit is fully operational.
Thetubingintheevaporatorsection is specifically sloped
to provide a continuous movement of liquid ammonia,
flowing downward by gravity through this section. If the
refrigerator is operated when it is not level and the ve-
hicle is not moving, liquid ammonia will accumulate in
sections of the evaporator tubing. This will slow the cir-
culation of hydrogen and ammonia gas, or in severe
cases, completely block it, resulting in a loss of cooling.
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
prevent this loss of cooling.
The vehicle needs to be leveled only so it is comfortable
to live in (no noticeable sloping of floor or walls).
When the vehicle is moving, the leveling is not critical,
as the rolling and pitching movement of the vehicle will
pass to either side of level, keeping the liquid ammonia
from accumulating in the evaporator tubing.
LP GAS OPERATION
Beforestartingtherefrigerator,check thatall the manual
gas valves are in the ON position. DO NOT forget the
manual shutoff valve on the rear of the refrigerator see
FIG. 1.
1. To start the refrigerator, turn knob A to the “GAS”
position.
2. Turn the thermostat knob B to position 4.
3. Push the button C in until it reaches the bottom - and
hold, push the button D for the piezo igniter several
timesto light theburner.This can be observed onthe
flame indicator E. When the flame is on, the red indi-
cator is in the green field, (ON).
4. After the gas is lit keep the button C pressed for 10
seconds.Releasethe button andcheck that theRED
indicator is in the GREEN field, (ON).
5. To shut off the refrigerator turn the knob A to “OFF”
position.
! WARNING

12 V OPERATION
Only operate your refrigerator on 12V when the engine
ofthevehicleis running - otherwiseyourbatterywill soon
be discharged.
1. Turn the knobA to the position marked “DC” for 12
voltsoperation.
2. Note: there is no thermostat function on 12 V DC
operation, the refrigerator works continuously.
3. To shut off the refrigerator turn the knobA to “OFF”
position.
REGULATING THE TEMPERATURE
The refrigerator is equipped with a thermostat that can
be adjusted by turning the knob B to different setting to
maintain the desired cabinet temperature.
At OFF Ingas operation,the thermostat closesitsmain
valve and the burner runs continuously at the
bypass rate, just enough to keep the burner lit.
In electrical operation, the contacts in the ther-
mostat are open and the heating elements are
off.
At MAX In gas operation, the thermostat allows the
burner to remain on high flame continuously. In
electric operation, the heating element is “ON”
continuously. Lowest cabinet and freezer tem-
peratures are obtained at this setting.

NOTE: Defrost water runs from the drip tray to a recep-
tacle at the rear of the refrigerator where it normally
evaporates. (See FIG. 1).
With a lot of defrost water as a result of heavy frosts
build up on the cooling fins, move the plastic drain tube
into a water tight bucket or container, (access through
louvered service panel on the outside of the vehicle).
When all frost has melted, wipe up the excess moisture
and empty the accumulated water from the bucket. Re-
place the drain tube to its original position.
Dry the interior of the refrigerator with a clean cloth.
Replace all food and set the thermostat to “MAX” for a
few hours, then reset the thermostat to its normal posi-
tion.
The thermostat can be adjusted between “MAX” and
“OFF” to obtain the desired cabinet temperature.
The closer the knob is to “MAX” - the colder the cabinet
temperature.Theclosertheknobisto“OFF” - the warmer
the cabinet temperature.
Whenthe thermostatreaches the set temperature, it will
cut the burner back to bypass or, in electric operation,
(230-240 VAC) shut off the heating element.
The setting of the thermostat is not critical, but we rec-
ommend it be adjust to maintain a dry frost on the cool-
ingfins.Adjustthethermostatknobcloserto“MAX”when
the outside temperature becomes warm.
HOW TO USE THE REFRIGERATOR
FOOD STORAGE COMPARTMENT
Thefood storage compartmentiscompletely closedand
unventilated,whichisnecessaryto maintain therequired
low temperature for food storage. Consequently, foods
having a strong odor or those that absorb odors easily
should be covered. Vegetables, salads etc. should be
covered to retain their crispness. The coldest positions
in the refrigerator are under the cooling fins and at the
bottom of the refrigerator. The warmer areas are on the
upper door shelves. This should be considered when
placing different types of food in the refrigerator.
FROZEN FOOD STORAGE
COMPARTMENT
Quick frozen soft fruits and ice cream should be placed
in the coldest part of the compartment, which is at the
bottom of the aluminum liner. Frozen vegetables, may
be stored in any part of the compartment.
Thiscompartmentisnotdesignedfordeeporquickfreez-
ing of food. Meat or fish, whether raw or prepared, can
be stored in the frozen food storage compartment pro-
vided they are precooled first in the refrigerator. They
canbestored about threetimes longer inthe frozen food
compartment as compared to the fresh food compart-
ment. To prevent food from drying out, keep it in cov-
ered dishes, containers, plastic bags or wrapped in alu-
minium foil.
Ice cubes can be made in the freezer compartment.
For faster ice making, the trays should be placed in di-
rectcontact with the bottom ofthe freezer compartment.
Ice making is accelerated if the thermostat knob B is
turned to the “MAX” setting.
It is a good idea to do this a few hours before the antici-
pated need for ice, but be sure to turn the thermostat
back to the normal setting when the ice is formed.
Foodinthe lower compartmentmay befrozen if thether-
mostat is left on “MAX”.
DEFROSTING
Shut off the refrigerator by turning the knob A to “OFF”
position.Empty the refrigerator, leaving the drip tray un-
der the finned evaporator, and the cabinet and freezer
doors open. Defrosting time can be reduced by filling
theicetrayswith hot water andplacingtheminthefreezer
compartment.
! CAUTION
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 compartment.
They can create a leak in the ammonia system.
CLEANING THE REFRIGERATOR
Cleaning the refrigerator is usually done after it is de-
frosted or put into storage. To clean the interior liner of
the refrigerator, use lukewarm weak soda solution. Use
only warm water to clean the finned evaporator, gasket,
ice tray and shelves.
NEVER use strong chemicals or abrasives to clean
these parts, as the protective surfaces will be dam-
aged. It is important to always keep the refrigerator
clean.
SHUT- OFF (STORAGE PROCEDURE)
To shut off the refrigerator, turn the knob A to “OFF”
position. If the refrigerator will not be in operation for a
periodofweeks,itshouldbeemptied, defrosted, cleaned
andthe doors leftajar.Theice trays shouldalso bedried
and kept outside the cabinet.
DO NOT store explosive substances in the refrig-
erator, such as cigarette lighter gas, gasoline, ether
or the like.
NOTE: Sodium chromate is used for corrosion protec-
tion (less than 2 weight % of the coolant).

3. PERIODIC MAINTENANCE
To keep your Dometic refrigerator operating efficiently
and safely, periodic inspection and cleaning of several
components once or twice a year is recommended.
A. It is important to keep the area at the back of the
refrigerator clean. Check the lower vent, upper vent
and area between these openings for any obstruc-
tions such as bird/insect nests, spider webs, etc.
Clean the coils on the back of the refrigerator. Use a
soft bristled brush to dust off the coils.
It is important to keep the refrigerator area free from
combustible material, gasoline and other flammable
vapors or liquids.
NOTE: The following maintenance is required once or
twice a year, but should only be done by a qualified ser-
viceman who is familiar with LP gas systems and refrig-
erators.
B. Check all connections in the LP gas system (at the
back of the refrigerator) for gas leaks. The LP gas
supply must be turned on. Apply a non-corrosive
bubble solution to all LP gas connections.
