INSTALLING REFRIGERATOR IN
ENCLOSURE
NOTE: DO NOT install the appliance directly on
carpeting. Carpeting must be removed or
protectedby a metal or woodpanel beneath
the appliance, which extends at least full
width and depth of the appliance.
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. Also apply a sealing strip to the foremost floor of
the enclosure as shown in fig. 6. The sealing should
provide a complete isolation of the appliance’s combus-
tion system from the vehicle interior.
NOTE: Be careful not to damage the sealing strip when
the refrigerator is put in place.
Failure to follow the sequence in securing refrigerator in
enclosure can cause leakage between the frame and
cabinet.
When installing the refrigerator, the installer must block
the space between the storage cabinet and the top of
the refrigerator, otherwise heat will become trapped in
this space, making the top of the refrigerator hot, thus
reducing the efficiency of the unit.
Securing the Refrigerator
After the refrigerator is put in place, (insuring a combus-
tion seal at the front frame), the refrigerator is to be se-
cured in the enclosure with five screws (not included).
The screws have to be installed in the following order:
STEP 1: Four screws installed through the front
frame. See fig. 7.
STEP 2: One screw installed in rear base. See fig. 7.
In the parts bag there are plugs to be snapped in the
front frame to cover the four screw heads.
Drain water hose
Ahole must be drilled through flooring see FIG. 8.
The installer MUST make sure that the hose does not
kink when run through the floor. Seal around the hose
that goes through the drilled hole. If a longer hose than
supplied is required to get the water to drain outside of
thevehicle,the installerwillhavetosupplythe extralength
of hose.
GAS CONNECTION
Hook up to the gas supply line is accomplished at the
manual gas valve, which is furnished with a 3/8" SAE
(UNF5/8"-18) male flare connection.All completed con-
nections should be checked for leaks with soapy water.
DO NOT use a flame to check for gas leaks.
Thegassupplysystemmustincorporateapressureregu-
lator to maintain a supply pressure of not more than 11
inches water column.
Whentestingthegassupply system at test pressures in
excessof 1/2psi,therefrigeratorand itsindividualshutoff
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-
nectiontothegassupply arerequired, 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 and switch to GAS mode.
(See start up instructions).
2. Check that the gas flame is lit and the GAS mode
indicator lamp (C) is on.
3. Close the manual gas shutoff valve at the back of
the refrigerator. (See FIG. 1).
4. Wait for one minute.The CHECK indicator lamp (E)
should be on and the GAS mode indicator lamp (C)
should be off.
5. Remove protection cover (see FIG. 1) and open the
manual gas shutoff valve. Do not change any button
positionson the control panel.Apply a non-corrosive
commercial bubble solution to the burner jet orifice.
6. Nobubblesshouldappear atthe openingoftheburner
jet orifice. The presence of bubbles indicates a de-
fective gas safety shutoff, and service is required.
7. If no bubbles were present at the burner jet orifice, it
should be rinsed with fresh water. Be careful not to
damage the burner jet orifice. Replace cover and
press the main power ON/OFF button (1) OFF and
back ON. Normal operation of the burner should re-
turn.Allow the burner to operate for a minimum of 5
minutes.
ELECTRICAL CONNECTION
120 Volts AC Connection
The refrigerator is equipped with a three-prong
(grounded)plug forprotection againstshockhazards and
shouldbepluggeddirectlyintoaproperlygroundedthree-
prongreceptacle.DO NOTcut or remove the grounding
prong from this plug. The free length of the cord is 2
feet.andthereforerecommendedthat the receptaclebe
located to the left side of the refrigerator (viewed from
the rear) and approximately 4-6 inches from the floor
(see FIG. 8). This allows easy accessibility through the
ventdoor. The cord shouldberoutedtoavoidcontacting
the burner cover, flue cover, or any other components
that could damage the cord insulation.
12 Volts DC Connection
This refrigerator model require a continuous 12 volt DC
supply to maintain the automatic energy system.
The connection is made to the positive (+) and negative
(-) terminals of the terminal block on back of the refrig-
erator. (See FIG. 1). Correct polarity must be observed
when connecting to the DC supply.
DO NOT use the chassis or vehicle frame as one of the
conductors. Connect two wires at the refrigerator and
route to the DC supply.
The distance the current must travel from the battery to
the refrigerator dictates the AWG wire size to be used.
Should the wire be too small for the distance, a voltage
drop will result.
The voltagedrop affects the wattage output of the12 volt
cartridge heater and resultant refrigerator performance.
The12 voltDCheater isfused witha30 amp. in-lineblade
fuse.
Recommended wire sizes are shown below.

INSTRUCTIONS
IMPORTANCE OF LEVELINGA
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.
Thetubing intheevaporator sectionisspecifically 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.
OPERATION
Beforestartingthe refrigerator,check that all 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.
This refrigerator is equipped with a semi Automatic
Energy Selector (AMES) control system, which can be
set to automatically select either 120 volt AC or LP gas
operation (AUTO mode), or if desired LPgas only (GAS
mode). On 3-way model the control system can manu-
ally be set to DC operation (DC mode).
The refrigerator controls will work down to 9.6 volt DC.

INSTRUCTIONS FOR MOUNTING THE
DOOR PANEL
Therefrigerator is normally deliveredwithoutdoorpanel.
The lower decoration strip and parts bag are taped in-
side the door.
Before starting the mounting work, check that the panel
dimensions are in compliance with those given in the
Table and the instructions are read thoroughly.
We recommend to mount the panel on the door before
the refrigerator is installed in the enclosure.
When mounting the panel, proceed as follows:
•Slide the panel from the bottom of the door into the
grooves on the vertical edges of the door .
•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.
•Put the decoration strip across the door and fasten
it with three screws from the parts bag.
Most LP gas appliances used in recreational ve-
hicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is pos-
sible 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 out-
side.

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 recommended that an automatic cut-out relay
be installed between the battery and the refrigerator
toggle switch so that the refrigerator will not draw
current when the ignition of the vehicle is switched
off.
Alternatively, a suitable plug and receptacle should
be installed in the 12 Volt supply line, so that the
refrigerator can be disconnected from the supply,
as necessary.
LIMP MODE OF OPERATION
This control system contains a feature where it will con-
tinue to operate the cooling system in the event of a fail-
ureof amajor operatingcomponent.Twodifferentmodes
of operation can occur in this category.
Iffor somereason thedisplaymodule becomesnon func-
tional, the control system will revert to full automatic op-
eration selecting the best energy source available with
AC, DC and GAS priority. The temperature of the refrig-
erator will be maintained at the MID position within nor-
maltemperaturetolerances.The power module willcon-
tinually attempt to reestablish operation of the display
module.

HOW TO USE THE REFRIGERATOR
FOOD STORAGE COMPARTMENT
Thefoodstorage compartmentiscompletely closed and
unventilated,which is necessarytomaintaintherequired
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.
Thiscompartmentis notdesignedfordeepor quickfreez-
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
canbe stored about three timeslongerinthe frozen food
compartment as compared to the fresh food compart-
ment. To prevent food from drying out, keep it in covered
dishes, containers, plastic bags or wrapped in aluminum
foil.
Ice cubes can be made in the freezer compartment.
Forfaster icemaking,the trays shouldbeplaced indirect
contact with the bottom of the freezer compartment.
Ice will be made more rapidly if the thermostat is set at
its highest position.
It is a good idea to do this a few hours before the antici-
pated need for ice, but be sure to move back to normal
setting,usually about mid setting whentheiceis formed.
Foodinthe lower compartmentmaybefrozenif the set-
ting is left on “COLDEST” position.
Total Refrigerated Volume 3 cu.ft.
DEFROSTING
Shutoffthe refrigerator by pressingthemainpowerON/
OFF button to the UP (OFF) position. Empty the refrig-
erator, leaving thedrip tray under the finnedevaporator,
andthecabinetandfreezerdoorsopen.Defrostingtime
canbe reduced by filling the ice trays with hotwater and
placing them in the freezer compartment.
When all the frost has melted, dry the interior of the re-
frigeratorwithacleancloth.Replaceallfoodand set the
thermostat to the COLDEST temperature setting for a
few hours. Then reset the thermostat to the desired set-
ting, usually at mid setting.
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)
Shutoffthe refrigerator by pressing the main power ON/
OFF button to the UP (OFF) position.
If the refrigerator will not be in operation for a period of
weeks,itshouldbeemptied,defrosted,cleanedandthe
doors left ajar. The ice trays should also be dried and
kept outside the cabinet.
! CAUTION
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).
! WARNING
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.

MAINTENANCE & SERVICE
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 per-
formed by a qualified technician who is familiar with
LP gas systems and refrigerators.
1. HEATER
The heat necessary for the operation of an absorption
cooling unit is supplied by an electric heater mounted in
a pocket of the boiler system.
Thismodelisequipped with two electric heaters, one for
120 voltAC and one for 12 volt DC.
To replace the heater proceed as follows:
1. Unplug the refrigerator power cord from the 120-
voltAC outlet.
2. Disconnect or shut off the 12 volt DC power to the
refrigerator.
3. Remove the power module cover see FIG. 1.
4. Disconnect the 120 VAC heater leads from the
power module or the 12 V DC lead from the relay.
5. With a pair of pliers unfold the lug holding the lid
of the boiler casing and open the lid.
6. Remove some insulation wool so that the heater
is accessible.
7. Turn and lift the heater out of its pocket.
8. Fit the new heater into the pocket.
9. Connect the heater leads and put on the power
module cover.
10. Reset the insulation and close the lid of the boiler.
2. REFRIGERATOR REMOVAL
Before working on the refrigerator, make sure the AC
voltageand DCvoltageleads aredisconnected.Shutoff
the gas supply at the LP tank. Disconnect the gas sup-
ply line at the rear of the refrigerator, see FIG. 1.
Alwaysuseabackupwrench when loosening and tight-
eningconnections.
Cap the gas supply line, loosen the screws anchoring
the refrigerator to the enclosure and slide the refrigera-
tor out of the compartment.
Whenreplacingtherefrigeratormake sure that the seal-
ing strips are properly positioned.
Replacement is the reverse of removal. Check all con-
nections for gas leaks.
Refer to section INSTALLATION, page 4 to 8.
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.
The appearance of bubbles indicates a leak and
should be repaired immediately by a QUALIFIED
SERVICEMANWHO IS FAMILIARWITHGAS SYS-
TEMAND REFRIGERATORS.
! WARNING
DO NOT use a flame to check for gas leaks.

C. Check the AMES control system by connecting/dis-
connecting 120 voltAC power, start/stop the engine,
etc. Compare the operation with the operation de-
scribed in section Operating Instructions.
D. TheLP gaspressure shouldbechecked andthemain

rectoperatingpressureis11 inches of water column.
The correct place to take the LP gas pressure is at
the test port just ahead of the burner jet. (See FIG. 9).
E. Inspect the flue baffle. It should be reasonably clean
and free of soot. Heavy soot formation indicates im-
proper functioning of the burner. The flue and burner
both require cleaning in the following manner:
1. Unplug the refrigerator power cord from the 120-volt
AC outlet. (See FIG. 8).
2. Disconnect or shut off the 12 volt DC power to the
refrigerator.
3. Turn manual shutoff valve to OFF. (See FIG. 1 & 9).
4. Remove cover from the burner housing. (See fig. 1).
5. Disconnect the wire from the high voltage electrode.
6. Remove the burner mounting screw and remove the
burner assembly. (See FIG. 9).
7. Remove the wire and flue baffle from the top of flue
tube. Clean the flue from the top using a flue brush.
Blowing compressed air into the flue will not prop-
erly clean soot and scale out of the flue tube.
Replace the flue baffle.
8. Cleanburnertube with a brush. Blow out burner with
compressed air.
9. Beforeremovingburner jet, clean burner areaofsoot
andscale that fell outofflue tube. Removetheburner
jet. Soak the jet in wood alcohol and blow it out with
compressed air. Reinstall and tighten burner jet.
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.
