the mobile home or recreational vehicle. Louver ope-
nings must have a minimum dimension of 1/4 inch for air
supply or venting of combustion products.
Proper installation requires one fresh air intake and one
upper exhaust vent. The ventilation kits shown in this
instruction manual have been certified for use with the
refrigerator model listed in the Table. For "Certified Vent
System Kits" see Section B. The ventilation kits must be
installed and used without modification. An opening
toward the outside at floor level in the refrigerator com-
partment must be provided for ventilation of heavier-
than-air fuel gases. The lower vent of the recommended
kits is provided with properly sized openings. The flow of
combustion and ventilation air must not be obstructed.
The lower side vent is fitted with a panel which provides
an adequate access opening for ready serviceability of
the burner and control manifold of the refrigerator. This
should be centered on the back of the refrigerator.
3. CERTIFIED INSTALLATION
Certified installations require one upper side vent and
one lower side vent.
For certified vent system kits, see Section B.
For further information, contact your dealer or distributor.
4. METHOD OF INSTALLATION
The methods of installation are shown in FIG. 1 & FIG.

B. SECURING REFRIGERATOR IN 8. GAS CONNECTION
ENCLOSURE Hook-up to the gas supply line is accomplished at the
manual gas shutoff valve, which is furnished with a 3/8"
SAE (UNF 5/8” - 18) male flare connection. Always use
a backup wrench when connecting the gas supply line to
the gas inlet fitting. All completed connections should be
checked for leaks with a noncorrosive leak detector.
(See FIG. 6 - Gas inlet fitting may have a different orien-
tation than shown).

NOTE: Push refrigerator into enclosure until front frame
is tight against the cabinet. First, secure the frame to
cabinet with six screws. Second, install the two screws
to the floor at the rear of the refrigerator.
Failure to follow the sequence in securing the refrigerator
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 should be
blocked. The heat produced at the rear of the refrigerator
will become trapped in this space, making the top of the
refrigerator hot and reducing the efficiency. The gas supply system must incorporate a pressure
regulator to maintain a supply pressure of not more than

shutoff 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 psig, the appliance must be isolated
from the gas supply piping by closing its individual
manual! shutoff valve.
In case detailed instructions on the installation and
connection to the gas supply are required, contact your
dealer or distributor.

9. TESTING LP GAS SAFETY
SHUTOFF
The gas safety shutoff must be tested after the refrigera-
tor is connected to LP gas supply.
To test the gas safety shutoff, proceed as follows:
A. Start the refrigerator according to the instructions for
LP Gas Operation. See "Section C. Operation
Instructions."
B. Check that the gas flame is lit. Allow it to burn a few
minutes to ensure a full, stable flame.
C. Turn the gas safety valve (B, FIG. 8) to the "OFF"
position. Within 1-2 minutes the gas safety device
within the valve should automatically close. An
audible "click" from the valve may be heard.
D. Turn the gas safety valve to the "HIGH" position
(B, FIG. 8).
E. Without pushing in the knob (B, FIG. 8) of the gas
safety device, apply a commercial leak detection
solution to the burner jet. No bubbles should appear.
Bubbles indicate a gas leak and the safety valve must
be replaced by a qualified serviceman.
F. Rinse the burner jet with water. Light the burner and
allow it to burn for five minutes.
10. 120 VOLT AC ELECTRICAL
CONNECTION
The refrigerator is equipped with a three-prong (groun-
ded) plug for protection against shock hazards, and
should be plugged directly into a properly grounded
three-prong receptacle. DO NOT cut or remove the gro-
unding prong from this plug. The power cord should be
routed to avoid direct contact with the burner cover, fuel
cover or manual gas shutoff valve knob.
11. 12 VOLT DC CONNECTION
The 125 watt heating element operates the cooling unit
when the refrigerator is connected to the battery of the
vehicle. It has a current rating of about 10.5 amps; there-
fore, the wiring from the battery to the refrigerator must
be of heavy enough gauge to carry this load satisfactori-
ly without undue voltage drop. To ensure this, the mini-
mum size of wire to be used is 14 A.W.G. The terminal
block for connecting the 12V supply cable to the battery
is positioned at the lower lefthand corner of the rear side
(G, FIG. 8). From this terminal, the connection to the
battery should be made using ring-type clamps with
tightening bolts to ensure good contact with the battery
terminals. Polarity is not important, therefore it does not
matter which wire leads to which battery terminal.
DO NOT connect lights or any other electrical com-
ponents to the same circuit that is used by the refri-
gerator.
IMPORTANT:
To prevent the refrigerator from being left on and
draining the battery when the vehicle's engine is
not running and charging the battery, it is recom-
mended that an automatic cutout relay be installed
between the battery and the refrigerator toggle
switch so that the refrigerator will not draw current
when the vehicle ignition is switched off.
Alternatively, a suitable plug and receptacle should
be installed in the 12V supply line so that the refri-
gerator can be disconnected from the supply, as
necessary.
FUSE
A 12 amp (continuous rating) fuse should be incorpora-
ted in the wiring of the DC supply, as near to the battery
as possible. The fuse must be in the side of the wiring
which is not connected to the chassis. For example, if
the vehicle has a negative ground, the fuse must be in
the positive side of the wiring.
12. CHANGING DOOR HINGES
FROM ONE SIDE TO THE OTHER
If required, the door hinges can be moved to the opposi-
te side. Reverse the door hang in the following way:
A. Unscrew the upper hinge pin, taking care not to lose
the set of washers and bushings.
. Lift the door from the lower hinge pin. If decorative
door panel is to be installed, proceed to Step 13.
. Unscrew the pin and mount it on the opposite side
hinge.
. Unscrew the travel catch and mount it on the
opposite side.
. Replace door on lower hinge pin. Replace upper
hinge pin and bushings removed in Step A.
. Check that the door closes properly and seals all
around.

SECTION C. OPERATING INSTRUCTIONS
1. IMPORTANCE OF LEVELING A
REFRIGERATOR
In an absorption refrigerator system, ammonia is lique-
fied in the finned condenser coil at the top of the refrige-
rator. The liquid ammonia then flows into the evaporator
(inside the freezer section) and is exposed to a circula-
ting flow of hydrogen gas, which causes the ammonia to
evaporate, creating a cold condition in the freezer.
The tubing in the evaporator section is specifically slo-
ped to provide a continuous movement of liquid ammo-
nia downward by gravity through this section. If the
refrigerator is operated when it is not level and the
vehicle is not moving, liquid ammonia will accumulate in
sections of the evaporator tubing. This will stow the cir-
culation of hydrogen and ammonia gas, or in severe
cases, completely block it, resulting in a loss of cooling.
Remember to level the vehicle when stopping for more
than an hour, otherwise the cooling unit could be perma-
nently damaged due to overheating if it is left "ON".
When the vehicle is moving, the leveling is not critical as
the rolling and pitching motion of the vehicle will pass to
either side of level, keeping the liquid ammonia from
accumulating in the evaporator tubing.

Most LP gas appliances used in recreational
vehicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is possi-
ble that the gasoline fumes could enter this type of
appliance and ignite from the burner flame,
CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, it is recommended that all LP
gas appliances which are vented to the outside
should be shut off when refueling.
The refrigerator must be shut off during refueling.
B. ELECTRIC OPERATION
1. RM2191: DC OPERATION
On 12V DC operation, the temperature is controlled by a
thermostat. The thermostat knob (D, in FIG. 8) should be
set to position 4-5 in normal working conditions.
If the ambient temperature is high and/or fresh food is
put into the refrigerator you may set the refrigerator to a
higher position.
If you wish a higher temperature in the cooling compart-
ment, set the knob to a lower position.
2. RM2193: 12V DC / 120v AC OPERATION
In the case of the RM2193, the refrigerator works conti-
nuously on DC operation (no thermostat control).
On AC operation, the temperature is controlled by a ther-
mostat. The thermostat knob (D, in FIG. 8) should be set
to position 4-5 in normal working conditions. If the
ambient temperature is high and/or fresh food is put into
the refrigerator you may set the refrigerator to a higher
setting.
If you wish a higher temperature in the cooling compart-
ment, set the knob to a lower position.
3. TO TERMINATE ELECTRIC OPERATION
To terminate electric operation, turn the switch/es to the
"OFF" position (A in RM2191) and (A and E in RM2193).
NOTE: NEVER OPERATE THE REFRIGERATOR ON
MORE THAN ONE ENERGY SOURCE AT A TIME.
4.HOW TO USE THE REFRIGERATOR
A. FOOD STORAGE COMPARTMENT
The storage compartment is completely closed and
unventilated, which is necessary to maintain the required
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.
The refrigerator is designed for the storage of fresh
foods, milk, etc. It is not intended for the storage of fro-
zen food. The internal volume of the refrigerator is 1.7
cubic feet, net.
NEVER PUT HOT FOOD INTO THE REFRIGERATOR.
Avoid using large dishes and do not stack food or food
containers too closely as this interferes with the circulati-
on 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 in your household
refrigerator, or in the market.
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.
B. DEFROSTING
To defrost, take out any food, etc. then turn off the gas
valve or switch of the DC/AC supply to the refrigerator.
Leave the refrigerator door open and place a suitable
dish or other receptacle under the evaporator to catch
the defrost water.
When all the frost has melted, any remaining drops of
water in the refrigerator should be wiped up with a clean
cloth.
for: VU ae) \\|
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.

E. CLEANING
Cleaning the refrigerator is usually done after it is defro-
sted or put into storage. To ciean the interior of the refri-
gerator, use lukewarm water and a mild dishwashing
detergent. Use only warm water to clean the finned eva-
porator, 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.
F. SHUTOFF (STORAGE PROCEDURE)
Place the toggle switch(es) for DC and AC operation to
the "OFF" position or turn the gas valve to position
"OFF", as applicable. See FIG. 8.
When not in use, the refrigerator should be emptied, cle-
aned and dried and the door left open so that fresh air
can circulate inside.
The travel latch placed in the second hole will hold the
door ajar and allow air to circulate.
! WARNING
Most LP gas appliances used in recreational
vehicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is possi-
ble that the gasoline fumes could enter this type of
appliance and ignite from the burner flame,
CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, when refueling, shut off all LP
gas appliances which are vented to the outside.

TIPS FOR THE SERVICE TECHNICIAN
The user should be aware of service that must be done
on a regular schedule to keep the refrigerator operating
properly. The service should only be performed by a
qualified technician who is familiar with LP gas
systems and refrigerators.
1.REFRIGERATOR REMOVAL
Before working on, or removing the refrigerator, make
sure the electrical supply (AC and DC) is turned OFF
before leads are disconnected. Shut off the gas supply.
Disconnect and cap the gas supply line. Loosen the scr-
ews anchoring the refrigerator to the enclosure and slide
the refrigerator out of the compartment.
Replacement is the reverse of removal. Check all
connections for gas leaks.Refer to Section A, Item 1
through 13 of Installation Instructions.
2. PERIODIC MAINTENANCE
To keep a Dometic refrigerator operating efficiently and
safely, periodic inspection and cleaning of several com-
ponents once or twice a year is recommended.
10
A. It is important to keep the area at the back of the refri
gerator clean. Check the lower vent, upper vent and
area between these openings for any obstructions
such as bird/insect nests, spider webs, etc. Clean the
coils on the back of the refrigerator. Use a soft brist
led brush to dust off the coils..
NOTE: AVOID SPRAYING WATER THROUGH THE
REFRIGERATOR VENTS WHEN WASHING THE RV.
It is important to keep the refrigerator vent area free
from combustible material, gasoline and other
flammable vapors or liquids.
. 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 noncorrosive
bubble solution to all LP gas connections. The appea
rance of bubbles indicates a leak and should be
repaired immediately by a qualified serviceman
who is familiar with LP gas systems and
refrigerators.
! WARNING
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

3) To clean the burner, unscrew the screw (C) that fixes
the burner on the boiler tube and be careful in order
not to lose the washer.
4) Clean the inside of the burner.
5) To examine and eventually clean the burner jet,
unscrew the gas pipe union (K) and pull out the
burner jet (L).
Clean the jet by washing it in alcohol and blowing it
through with air.
NOTE: The jet fitted to this refrigerator is a size
"45" which is suitable for use on propane gas at
11 inches water column. The orifice in the jet is
very small and must never be cleaned by means
of a pin or similar instrument as this would
damage the orifice. It must only be cleaned as
described above.

DO NOT use a wire or pin when cleaning the
burner jet as damage can occur to the precision
opening. This can cause damage to the
refrigerator or
create a fire hazard.

7) Reassemble the components in the reverse order to
that described for removal, taking care to remake the
gas connections soundly, and not forgetting to refit
the flue baffle.
Reinstall the refrigerator in its recess. Connect the
gas and electrical supplies, and check for gas leaks.
Light the burner and check the appearance of the
flame to ensure that it is predominantly blue (when
the thermostat is at "HIGH"), then leave the
refrigerator on “test” for at least an hour.

3. TROUBLESHOOTING
If the refrigerator fails to work, check the following points
before calling a service technician:
A. Instructions for STARTING THE REFRIGERATOR,
Section C, have been followed.
. The refrigerator is level.
B.
C. If it is possible to start the refrigerator on any of the
connected sources of energy.
D
. If the refrigerator fails to work on GAS, check:
1) That the gas bottle is not empty.
2) That all LP Gas valves in the supply line to the
refrigerator are open.
NOTE: The following checks should be performed
only by a qualified technician.
3) That sparks are generated by the piezo ignitor.
4) That the flame continues to burn after releasing
the knob of the flame failure device (B, in FIG.8).
If not, the thermocouple may be loose or
defective.
E. If the refrigerator fails to work DC, check:
1) That the DC supply is connected to the
refrigerator.
2) That the fuse on the DC supply is intact.
3) That the DC switch is set to the "ON" position
(A, in FIG. 8).
4) That electrical thermostat is not set to the”0”
position (RM2191 only).
F. If the refrigerator fails to work on AC, check:
1) That the AC supply is connected to the
refrigerator.
2) That the fuse on the AC supply is intact.
3) That the AC switch is set to the "ON" position.
4) That the electric thermostat is not set to the "0"
position.
G. If the refrigerator is not cold enough it may be
because:
1) The ventilation is inadequate because of
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.
