SECTION A. INSTALLATION
2.VENTILATION
The installation shall be made in such a manner as to
separatethecombustionsystemfromthelivingspaceofthe
mobilehomeorrecreationalvehicle.Openingsinlowerside
ventforairsupplyorforventingofcombustionproductsshall
have a minimum dimension of not less than 1/4 inch.
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
installedandusedwithoutmodification.Anopeningtoward
theoutsideatfloorlevelintherefrigeratorcompartmentmust
beprovidedforventilationofheavier-than-airfuelgases.The
lowerventoftherecommendedkitsisprovidedwithproper
size openings. The flow of combustion and ventilation air
must not be obstructed.
NOTE: The upper vent should be
centered over the condenser coil
atthebackof the refrigerator.

Also apply a sealing strip to the foremost floor of the
enclosureandapplyasecondsealingstriptothebottomof
the trim strip on the front base as shown in FIG. 4. The
sealingshouldprovidecompleteisolationoftheappliance's
combustion system from the vehicle interior.
The dimensions shown in FIG. 3 will give you adequate
space for service and proper installation.

9.TESTING LP GAS SAFETY
SHUTOFF
Thegas safety shutoff must be tested after the refrigerator
is connected to LP gas supply.
Totestthegassafetyshutoff,proceedasfollows:
A. Start the refrigerator according to the instructions, with
120 volts AC disconnected. See " Section C. Operation
Instructions ."
B. Check that the gas flame is lit. In Auto mode, the Auto
mode indicator lamp (A) is on. See FIG. 10.
C. Close the manual shutoff valve at the back of the
refrigerator. (SeeFIG. 6)
D. Waitforoneminute.Thecheckindicatorlamp(B)should
now be lit and the gas flame extinguished.
E. Removecoverandopenthe manualgas valve.Apply a
noncorrosive commercial bubble solution to burner jet
(see FIG. 6).
F. Nobubblesshouldappearattheopeningoftheburnerjet.
Thepresenceofbubblesindicatesadefectivegassafety
shutoff, and service is required.
G. If no bubbles were present at the burner jet, the gas
safety valve is working properly. Rinse jet thoroughly
with fresh water before proceeding. Be careful not to
damage burner jet. Replace cover and turn the main
switch(1)OFFandbackON.(See" SectionC.Operation
Instructions,Item2.ControlPanel ").Normaloperationof
theburnershouldreturn.Allowtheburnertooperatefor
a minimum of 5 minutes.
WARNING
DO NOT use a flame to check for leaks.

1.IMPORTANCE OF LEVELING A REFRIGERATOR
Inanabsorptionrefrigeratorsystem,ammoniaisliquefiedin
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.
Thetubingintheevaporatorsectionisspecificallyslopedto
provide a continuous movement of liquid ammonia down-
ward by gravity through this section. If the refrigerator is
operated when it is not level and the vehicle is not moving,
liquidammoniawillaccumulateinsectionsoftheevaporator
tubing.Thiswillslowthecirculationofhydrogenandammo-
niagas, orin severecases,completely blockit, resultingin
a loss of cooling.
Any time the vehicle is parked for several hours with the
refrigerator operating, the vehicle should be leveled to
preventthislossofcooling.Thevehicleneedstobeleveled
only so it is comfortable to live in (no noticeable sloping of
floors or walls).
Whenthevehicleismoving,thelevelingisnotcriticalasthe

4. HOW TO USE THE REFRIGERA-
TOR
A. FOODSTORAGECOMPARTMENT
The food storage compartment is completely closed and
unventilated,whichisnecessarytomaintaintherequiredlow
temperatureforfoodstorage.Consequently,foodshavinga
strong odor or those that absorb odors easily should be
covered. Vegetables, salads, etc. should be covered to
retaintheircrispness.Thecoldestpositionsintherefrigera-
tor are under the cooling fins and at the bottom of the
refrigerator.Thewarmerareasareontheupperdoorshelves.
This should be considered when placing different types of
foodintherefrigerator.
B. FROZENFOODSTORAGECOMPARTMENT
Quickfrozensoftfruitsandicecreamshouldbeplacedinthe
coldestpartofthecompartmentwhichisonorjustbelowthe
freezershelf.Frozenvegetables,maybestoredinanypart

three times longer in the frozen food compartment as
compared to the fresh food compartment. To prevent food
fromdryingout,keepitincovereddishes,containers,plastic
bagsor wrappedinaluminum foil.
C. ICEMAKING
Ice cubes can be made in the ice tray placed in the freezer
compartment. The tray should be filled with water to within
1/4" (5mm) from the top. For faster ice making, the tray
should be placed in direct contact with the freezer shelf.
Toreleasetheicecubes,seizethetraywithbothhandsand
twistthetray. Cubesnotrequiredshouldbereplaced inthe
tray. Refill the tray with water and replace the tray on the
freezershelf.
Ice will be made more rapidly if the thermostat is set at its
highestposition.Itisagoodideatodothisafewhoursbefore
the anticipated need for ice, but be sure to move the
thermostatbacktonormalsetting,usuallyaboutmid-setting
whentheiceisformed.Foodinthelowercompartmentmay
be frozen if the setting is left on "MANUAL" position.
C. DEFROSTING
ShutofftherefrigeratorbypressingthemainpowerON/OFF
button to the UP (OFF) position. Empty the refrigerator,
leaving the drip tray under the finned evaporator, and the
cabinet and freezer doors open. Defrosting time can be
reducedbyfillingtheicetraywithhotwaterandplacingiton

CAUTION
DO NOT use a hot air blower. Permanent damage could
resultfromwarpingthe metalor plasticparts.DONOTuse

G.CLIMATECONTROL
Duringthesummermonthsofhightemperatures and
humidity, the metal frame between the freezer and fresh
foodcompartments may have water droplets forming. The
number of water droplets will increase if the vehicle isn't
airconditionedduringthesemonths.
Thisrefrigerator comes standard with a 12 volt(DC)
climatecontrolthat will evaporate the water droplets when
they form.
To have this climate control on, you position the switch
(See "C", Fig. 10) located beneath the top decorative
strip that houses the control panel to ON. The climate
control can be left on continuously or only used when
temperaturesrequireit.
NOTE: The climate control will draw 12 volts DC power
continuously when in the ON position. It should be turned
OFF when a charging source is not available.
Most LP gas appliances used in recreational ve-
hiclesareventedtotheoutsideofthevehicle.When
parkedclosetoagasolinepump,itispossiblethat
the gasoline fumes could enter this type of appli-
anceandignitefromtheburnerflame,CAUSINGA
FIRE OR AN EXPLOSION.
FORYOURSAFETY,whenrefueling,shutoffallLP
gas appliances which are vented to the outside.
1.REFRIGERATOR REMOVAL
Beforeworkingontherefrigerator,makesuretheACvoltage
and DC voltage leads are disconnected. Shut off the gas
supply.Disconnectthegassupplyline.Capthegassupply
line, loosen the screws anchoring the refrigerator to the
enclosureandslidetherefrigeratoroutofthecompartment.
Replacement is the reverse of removal. Check all connec-
tions for gas leaks. Refer to Section A, Item 1 to 12 of
Installation Instructions .
2.PERIODIC MAINTENANCE
TokeepyourDometicrefrigeratoroperatingefficiently and
safely, periodic inspection and cleaning of several compo-
nents once or twice a year is recommended.
A.It is important to keep the area at the back of the
refrigeratorclean.Checkthelowervent,upperventand

dust off the coils.
It is important to keep the refrigerator area free from
combustible material, gasoline and other flammable
vapors or liquids.
B.CheckallconnectionsintheLPgassystem(attheback
oftherefrigerator)forgasleaks.TheLPgassupplymust
beturnedon.Applyanoncorrosivebubblesolutiontoall
LP gas connections. The appearance of bubbles indi-
cates a leak and should be repaired immediately by a
QUALIFIED SERVICEMAN WHO IS FAMILIAR WITH
LP GAS SYSTEMS AND REFRIGERATORS.
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
C.Check the control system by connecting/disconnecting
120 volt AC power. Compare the operation with the
operationdescribedin SectionC.OperationInstructions .
NOTE:Thefollowingmaintenanceisrequiredonceortwice

who is familiar with LP gas systems and refrigerators.
D.The LP gas pressure should be checked and the main
regulatorreadjustedifpressureisincorrect.Thecorrect
operating pressure is 11 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. 12).
