A. INSTALLATION
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 from the living
space.
Make sure that there is a complete seal between the front
frame of the refrigerator and the top, sides and bottom of
theenclosure. Alengthofsealingstripisappliedtotherear
surface of the front frame for this purpose. Also apply a
sealing strip to the foremost floor of the enclosure and
apply a second sealing strip to the bottom of the trim strip
on the front base as shown in FIG. 4. The sealing should
provideacompleteisolationoftheappliance'scombustion
system from the vehicle interior.
B. CONDENSATE DRAIN HOLE:
A hole must be drilled through flooring "L" (FIG. 2). This
holemustbedrilledin the one-inch clearance "M" (FIG.2).
The installer MUST make sure that the hose does not kink
whenrunthroughthefloor.Sealaroundthehosethatgoes
through the drilled hole. If a longer hose than supplied is
requiredto get the water to drainoutsideofthevehicle,the
installer will have to supply the extra length hose.

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 satisfactorily
without undue voltage drop. To ensure this, the minimum
size of wire to be used is 14 A.W.G. The terminal block for
connecting the 12V supply cable to the battery is posi-
tionedatthelowerleft-handcorneroftherearside(G,FIG.
8).Fromthis terminal, the connection tothebattery should
be made using ring-type clamps with tightening bolts to
ensure good contact with the battery terminals. Polarity is
notimportant,thereforeitdoesnotmatterwhichwireleads
to which battery terminal.
DO NOT connect lights or any other electrical compo-
nents to the same circuit that is used by the refrigera-
tor.

tively, a suitable plug and receptacle should be
installed in the 12V supply line so that the refrig-
erator can be disconnected from the supply, as
necessary.
FUSE
A 12 amp (continuous rating) fuse should be incorporated
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

evaporator tubing. This will slow the circulation of hydro-
gen 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.

In an absorption refrigerator system, ammonia is liquefied
in the finned condenser coil at the top 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.
The tubing in the evaporator section is specifically sloped
to provide a continuous movement of liquid ammonia
downward by gravity through this section. If the refrigera-
tor is operated when it is not level and the vehicle is not
moving, liquid ammonia will accumulate in sections of the

3. OPERATING INSTRUCTIONS
A. LP GAS OPERATION
After initial installation, servicing, or changing gas cylin-
ders,etc.,thegasline may contain some air which should
be allowed to escape by briefly turning on the refrigerator
or other gas appliances. This will ensure that the flame
lights immediately. See FIG. 8 for control location and
identification.
1) Open the shutoff valve of the gas bottle. Check
that there is enough gas. Open any on-board
shutoff valve which is in the gas line to the refrig-
erator.
2) Open the lower vent at the rear of the refrigerator
on the outside of the vehicle, and switch the
electrical toggle switch/es (A in RM2191) and (A
and E in RM2193) to the "OFF" position.
3) Turn the gas thermostat control (B) to the highest
setting.
4) Depress the knob (B) of the flame failure device,
turn it to position "HIGH", and hold it down while
depressing the piezo igniter button (C) several
times in quick succession (a click should be heard
each time it is depressed).
5) Keep the knob depressed for a further 10-15
seconds.
6) Release the knob and check for flame by looking
through the opening in the metal burner cover.
7) If the burner has not lit, repeat the lighting proce-
dure. If the burner fails to light within a couple of
attempts, contact a qualified technician or your
dealer.
NOTE:Therefrigeratorhasaflamefailure devicewhich
will automatically shut off the gas to the burner if the
flame is blown out. While the knob (B) is being held in,
this device is temporarily inoperative.
8) If the ambient temperature is above 80°F and/or
the door of the refrigerator is opened frequently
the knob should be left in the "HIGH" position.
9) To terminate gas operation, turn knob (B) to the
"OFF" position.
DO NOT attempt to operate the refrigerator by both gas
and electricity at the same time. Always ensure that
one method of operation is turned off before using the
alternate energy source.

The refrigerator is designed for the storage of fresh foods,
milk, etc. It is not intended for the storage of frozen food.
Theinternalvolumeoftherefrigeratoris1.7cubicfeet,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 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 in your household refrig-
erator, 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. 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 shelf.
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 possible that the
gasoline fumes could enter this type of appliance and
ignite from the burner flame, CAUSING A FIRE OR AN
EXPLOSION.
FORYOUR SAFETY, it isrecommended that all LPgas
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
On12V DC operation, the temperatureis 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 refrigera-
tor to a higher position.
If you wish a higher temperature in the cooling
compartment, set the knob to a lower position.
2. RM2193: 12V DC / 120v AC OPERATION
In the case of the RM2193, the refrigerator works
continuously on DC operation (no thermostat con-
trol).
On AC 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 setting.
If you wish a higher temperature in the cooling
compartment, set the knob to a lower position.
3. TO TERMINATE ELECTRIC OPERATION

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
therefrigeratorareunderthecoolingfinsandatthebottom
oftherefrigerator.Thewarmerareasareontheupperdoor
shelves. This should be considered when placing different
types of food in the refrigerator.

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 obstructions
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.
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 flam-
mable vapors or liquids.
B. CheckallconnectionsintheLPgassystem(attheback
of the refrigerator) for gas leaks. The LP gas supply
must be turned on. Apply a noncorrosive bubble solu-
tion to all LP gas connections. The appearance of
bubbles indicates a leak and should be repaired imme-
diately by a qualified serviceman who is famil-
iar with LP gas systems and refrigerators.
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
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
screws 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 compo-
nents once or twice a year is recommended.
E. CLEANING
Cleaningtherefrigeratorisusuallydoneafteritisdefrosted
or put into storage. 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 chemi-
cals 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)
Placethetoggleswitch(es)forDCand 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,
cleaned and dried and the door left open so that fresh air
can circulate inside.
Thetravellatchplacedinthesecondholewillholdthedoor
ajar and allow air to circulate.
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 possible 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.

C. Examination and Cleaning of Flue, Burner and Jet
Once or twice a year, look through the opening (see FIG.
9) in the burner box and examine the appearance of the
burner flame which should be predominantly blue in color
whenthe gas thermostat knobis set to itshighestposition.
(Refer to FIG. 10).
If this is not the case, and if you have checked the chapter
"Generals", the flue, burner, jet, etc. should be cleaned.
FIG. 9
D. Cleaning of Burner, Burner Jet (Refer to FIG. 11)
Proceed as follows:
1) Turn off the gas at the gas bottle.
2) By using a phillips screwdriver, remove the screw (B)
and carefully withdraw the burner cover box. Clean the
inside of the box of soot and other deposits.
3) To clean the burner, unscrew the screw (C) that fixes
theburner on theboiler tube and be careful in ordernot
