Depth “D” Dimensions Requirement with PlasticVent System is Dependant on Vehicle Side Wall Thickness. If the Vehicle Side Wall Thickness is less than

1,5 Inches ( 38mm ), the Recessed Depth Dimensions will be required to be Increased Proportionally to the Vehicle Wall Thicknes.

A. INSTALLATION

The refrigerator must be installed in a substantial enclo­sure 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.

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
the vehicle, the installer will have to supply the extra

length hose.

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 applied
to the rear 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 provide a complete isolation of the

appliance’s combustion system from the vehicle interior.

FIG. 4

B. CONDENSATE DRAIN HOLE:

C. SECURING REFRIGERATOR IN

ENCLOSURE

The refrigerator is installed in the enclosure with eight
screws. Six screws are in the front frame and two are in
the plate on the rear. See FIG. 5.

FIG. 5

(3) Screws on

each

ide of frame

(2) Screws-

.

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 dimensions shown in FIG. 3 will give you adequate

space for service and proper installation.

8. GAS CONNECTION

Hook-up to the gas supply line is accomplished at the
manual gas shutoff valve, which is furnished with a 318”
SAE (UNF 98” - 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 orien­tation than shown).

TO
REFRIGERATOR

When testing the gas supply system at test pressures in

excess of l/2 psig, the refrigerator and its individual
shutoff valve must be disconnected from the gas supply
piping system.

When testing the gas supply system at pressures less
than or equal to l/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 refrigera­tor 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 (D, FIG. 6) to the “OFF”

position. Within l-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 “ON” position

(D, FIG. 6).

E. Without pushing in the knob (D, FIG. 6) 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’A~ ELECTRICAL
CONNECTION

. .

The refrigerator is equipped with a three-prong (groun­ded) 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&ding 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; there­fore, 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 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 recom­mended 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 refri­gerator can be disconnected from the supply, as
necessary.

I I

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 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 opposi­te 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 bushrngs.

B. Lift the door from the lower hinge pin. If decorative

door panel is to be installed, proceed to Step 13.

C. Unscrew the pin and mount it on the opposite side

hinge.

D. Unscrew the travel catch and mount it on the

opposite side.

E. Change the cover plate and travel lock plate in top of

door frame to opposite side. Use a screwdriver to
press down on one edge of the cover plate. The
opposite edge will rise above the frame. Use a knife
blade under the raised edge to pop it out. See FIG. 7.

Use needle-nosed pliers to carefully lift lock plate out
of door frame. See FIG. 7.

SECTION C. OPERATING INSTRUCTIONS

1 JMPORTANCE 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 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 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 slow the
circulation 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.

2. CONTROLS

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 refrigerator.

Open the lower vent at the rear of the refrigerator on
the outside of the vehicle, and switch the electrical
toggle switch/es (A and B) to the “OFF” position.

Turn the gas thermostat control (F) to the highest

setting.
Depress the knob (D) of the flame failure device, turn

it to position “ON”, and hold it down while depres
sing the piezo igniter button (E) several times in quick
succession (a click should be heard each time it is
depressed).

Keep the knob depressed for a further 1 O-l 5
seconds.

Release the knob and check for flame by looking
through the opening in the metal burner cover.

If the burner has not lit, repeat the lighting procedure.
If the burner fails to light within a couple of attempts,
contact a qualified technician or your dealer.

8)

9)

In normal ambient conditions, the thermostat should

be set between 3-5. If you wrsh a colder temperature
inside the compartment, set the thermostat to a
higher position.

If the ambient temperature is higher than about 7O”F,
the thermostat should be set to its highest position.

To terminate gas operation, turn knob (D) to the
“OFF” position.

DO

NOT attempt to operate the refrigerator by

both gas and electricity at the same time. Always

c

ensure that one method of operation IS turned off
before using the alternate energy source.

NOTE: The refrigerator has a flame failure device

which will automatically shut off the gas to the bur-

ner if the flame is blown out. While the knob (D) is
being held in, this device is temporarily inoperative.

8

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, 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

120V AC OPERATION
To start 120V AC operation:

1.) Terminate gas operation by turning the knob of the
gas control device (D in FIG.8) to the “OFF” position.

2.) If the refrigerator is in 12V DC mode, switch the 12C
DC switch (A in FIG.8) to the “OFF” position.

3.) Check that the 120VAC’supply cord is connected

,and that AC- is available.

4.) Switch the 120V AC toggle switch (B in FIG8) to the
“ON” position.

5.) On 120V AC operation, the temrjerature is controlled

by a thermostat. The thermostat knob (C in FIG.8)

should be set to position 35 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 positions.

6.) To terminate 120V AC operation, switch the AC
toggle switch (B in FIG.8) to the “OFF” position.

DC ELECTRIC OPERATION

The DC operation is mainly designed to let the cooling
unit of the refrigerator work while being on the road.

To start 12V DC operation, proceed as follows:

1.) Terminate Gas operation by turning the knob of the
gas control device (D in Fig. 8) to the “OFF” position.

2.) Start 12V DC operation by switching the 12V toggle
switch (A in Fig.8) to the “ON” position.

Whenever possible, the cabinet should be precooled,
together with its contents, by starting up and running the
refrigerator on gas or AC for several hours, or overnight,
before switching to 12V DC and starting on a journey.

The 12V heating element is rated at 125 watts and has a
current consumption of about 10.5 Amps. The refrigera­tor should not therefore be left operating on 12V when
the engine is not running and charging the battery.

If an automatic cut-out relay, as recommended in Section
A, item 11, has not been installed, the refrigerator should
be switched off at the 12V toggle switch (A in Fig. 8)
soon after the engine is switched off, otherwise the
battery may become discharged.

3.TO TERMINATE DC OPERATION

To terminate DC operation, turn the DC switch to the
“OFF” position (A in FIG. 8).

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 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
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.

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.

9

E. CLEANING
Cleaning the refrigerator is usually done after it is defro-

sted 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 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,
cleaned 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.

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.

SECTION D. MAINTENANCE & SERVICE

,f

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

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 leaksRefer 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.

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.

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 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.

DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

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 when the gas thermostat knob is set to its highest
position. (Refer to FIG. 10).

If this is not the case, clean the flue, burner, jet, etc. (see
section D and E).

7) Reassemble the components in the reverse order to
that described above.

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 (6)
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
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).

6) Clean the jet by washing it in alcohol and blowing it
through with air.

NOTE: The jet fitted to this refrigerator is a size
“43” 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.

E. CLEANING OF FLUE TUBE, FLUE BAFFLE

Proceed as follows:

1) To clean the flue tube and the flue baffle, it is neces
sary to withdraw the refrigerator out of the recess.

See Section D, Item 7.

2)

By using a phillips screwdriver, remove the screw (B,
in FIG 11) and carefully withdraw the burner cover
box.

3) Place a piece of paper or cloth between the boiler
tube (E, in FIG 11) and the burner assembly, to catch
falling deposits.

4) Remove the “T-piece” (A, in FIG. 12) at the top of the

flue by unscrewing the screw (B, in FIG. 12) that fixes
it to the flue pipe.

5) Carefully takeout the flue baffle (C, FIG. 12) and
clean.

6) Clean the flue tube of soot, etc. with the aid of a spe
cial flue brush, available from your supplier.

1. Remove the refrigerator out of the recess as
described in item “2E”.

8) 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 “MAX”), then leave the
refrigerator on “test” for at least an hour.

2. Remove the boiler insulation cover (D in FIG. 12) and
remove the boiler insulation (E in FIG. 12).

3. Disconnect the faulty heater (F in FIG. 12) from the
terminals and remove it from the metal pocket on the
boiler.

4. Check that the new heater is of the correct type and
voltage and fit it in the boiler tube pocket in the same
way as the original was fitted.

5. Fit the boiler insulation round the boiler tube and re­place the boiler insulation cover.

The tip of the thermbcouple senses the flame. To replace
the thermocouple proceed ,as follows:

1. Disconnect the thermocouple connection at the flame
safety failure device (D in FIG. 8).

2. Remove the faulty thermocouple out of the burner and
put in a new one usig the description above for
changing the spark- electrode, step “F”.

3. Carefully tighten the thermocouple connection to the

falme safety failure device. Tighten it “finger- tight”

plus 114 turn. The plug must be properly tightened to

the safety device to ensure good contact.

Do not overtighten!

H. Lubrication
No lubrication is required to any part of the refrigerator or

gas controls.

I. Electric equipment
Before eventually replacing one of the electric heaters,

please check all the items of “3. TROUBLESHOOTING”.
If the fridge does not operate in one of the possible elec-

trical modes because a fuse is blown, examine the
supply wiring, cut- out relay (if installed) and repair any
faulty components or wires before fitting a new fuse and
reconnecting.

If current is available to the fridge (evt. measured with an
electricaltest- meter at the input- clamps) and the coolin­gunit at the back does not heat up after being “on” for at
least half an hour, this indicates that the heater has an
open circuit and needs replaced by a new one. (If an
electrical test- meter is available, the two heater leads
can be disconnected and the heater tested for
continuity).

A. Instructions for STARTING THE REFRIGERATOR,

Section C, have been followed.
B. The refrigerator is level.
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 (D, 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).

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 AC 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.

5) The ambient temperature is too high.

6) Too much warm food is loaded at one time.

7)

The door is not properly closed or the magnetic
sealing strip is defective.
