7. INSTALLING REFRIGERATOR IN

ENCLOSURE

NOTE: DO NOT install the appliance directly on carpeting.

Carpeting must be removed or protected by a metal or wood
panel beneath the appliance, which extends at least the full
width and depth of the appliance.

INSTALLATION: The refrigerator must be installed in a
substantial enclosure and must be level. When installing the
refrigerator in the enclosure, be certain there is a complete
seal between the front frame of the refrigerator and the top,
sides and bottom of 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 complete isolation of the appliance's
combustion system from the vehicle interior.
The dimensions shown in FIG. 3 will give you adequate

FIG. 5

each
Side)

FIG. 4

space for service and proper installation.
NOTE: Be careful not to damage the sealing strip applied to

the floor of the enclosure when the refrigerator is put in place.
The refrigerator is secured in the enclosure with six screws

and they must be installed in the following order:

First Two Screws installed on front base;
Second Two Screws installed in the top frame;
Third Two Screws installed in the rear base.

8.GAS CONNECTION

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. All completed connections
should be checked for leaks with an approved bubble
solution. (See FIG. 6 – Gas tubing may have a different
orientation than shown).

W ARNING

DO NOT USE A FLAME

TO CHECK FOR GAS LEAKS.

The gas supply system must incorporate a pressure regu­lator to maintain a supply pressure of not more than 13-1/2
inches water column, (static) no load.

TO
REFRIGERATOR

Failure to follow the sequence in securing refrigerator in
enclosure can cause leakage between the frame and cabi­net. The plastic caps are snapped in the front base to cover
the screw heads and the decoration strip is secured to top
frame. (See FIG. 5). 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 reduce the efficiency of the refrigerator.

When testing the gas supply system at test pressures in
excess of 1/2 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 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.

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 grounding prong from this
plug. The power cord should be routed to avoid direct contact
with the burner cover, flue cover or manual gas shutoff valve
knob. The free length of the cord is two feet and therefore
recommended that the receptacle be located to the left side
of the refrigerator (viewed from the rear) and approximately
six inches from the floor (see FIG. 7). This allows easy
access through the vent door.

FIG. 7

11. 12 VOLT DC CONNECTION

This refrigerator model requires a 12 volt DC power source
to operate the automatic energy system (even though it is
designed to operate on 120 volts AC and gas). The DC lead
connections are at terminals located at the rear of the
refrigerator. (See FIG. 6). One lead is marked positive (+)
and the other negative (–). Correct polarity must be observed
when connecting to the DC supply.

5

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.

12.INSTRUCTION FOR

MOUNTING DOOR PANEL

The refrigerator is normally delivered without the door pan­els. Before starting the mounting work, check that the panel
dimensions are in compliance with those given in the Table
on this page and the instructions are read thoroughly. When
mounting the panel, proceed as follows. (See FIG. 8)
A. On new refrigerators, the decoration strips are taped

inside the door. If installed on the door, remove the door
decoration strip (2) by removing its two screws (1).

B. Insert one vertical edge into the groove of the door

frame (3).

C. Bend the panel gently so that the free side of the panel

can be slipped into the corresponding groove of the door
frame (4). Slide the panel down into the groove of the
bottom frame (5).

D. Between the upper edge of the panel and door frame

there is a gap which should be covered by the decora­tion strip.

E. Put the decoration strip across the door so that the gap

is covered and push it upward (6). The tabs on the inside
of the strip should fit behind the flange of the door frame.
Secure the decoration strip with the two screws re­moved in Step A.

13. CHANGING DOOR HINGES FROM
ONE SIDE TO THE OTHER

Open the top door and remove the two screws holding the top
decoration. The screws are accessible from beneath.

Remove the top hinge pin and lift out the door. Remove
center hinge pin and lift out the lower door. Unscrew the
bottom hinge pin. Remove the plastic cap from the opposite
lower hinge and place it in the hole just "left empty" by the
lower hinge pin. Screw the lower hinge pin in the hole from
which the plastic cap was removed.

Before replacing the doors on the refrigerator, remove the
catches and move them to the opposite side of the cabinet.
Plastic caps for the empty holes are in the parts bag.
Remount the doors and the hinge pins in the reverse order of
their removal. Unscrew the handles and refasten them on the
opposite side of the door. Insert the plastic caps (from the
parts bag) into the holes left open on the doors. Before the
top decoration is refitted, check that the door closes easily
and the gasket seals well on all sides.

SECTION C. OPERATING INSTRUCTIONS

1.IMPORTANCE OF LEVELING A REFRIGERATOR

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 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.

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
floors or walls).

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.

A) START-UP INSTRUCTIONS

1) 12 volt DC supply must be available for the electronic
control to function.

2) Press the main power ON/OFF button (1) to the
DOWN position.

3) In AUTO mode operaiton, the temperature is con­trolled by a single temperature setting, on the energy
source selected by the control system. (See Sec. B)

4) In MANUAL mode operation, the refrigerator will run
continuously on the energy source selected by the
control system. (See Sec. C)

NOTE: The food in the lower compartment may be frozen

if the refrigerator is left on in the MANUAL mode.

B) AUTO MODE

1) Press the AUTO/MANUAL mode selector button (2)
to the DOWN position. The AUTO mode indicator
lamp (A) will illuminate.

2) When operating in the AUTO mode, the AUTO mode
indicator lamp (A) will illuminate. The control system
will automatically select between AC and GAS opera­tion with AC having priority over GAS. If the control
system is operating with AC energy and it then
becomes unavailable, the system will automatically
switch to GAS. As soon as AC becomes available
again the control will switch back to AC operation.

3) If 120 volts AC is not available, the control system will
automatically switch to GAS operation. Within 45
seconds the burner should be ignited and operating
normally. If unsuccessful, the CHECK indicator lamp
(B) will illuminate.
To restart an ignition attempt with the CHECK lamp
illuminated or to clear (turn off) the CHECK lamp,
press the main power ON/OFF button to the OFF and

MA NUAL

C

then ON position. The control system will attempt a
new 45 second ignition sequence.

4) On the initial refrigerator start-up on gas (120 volts AC
is not available), it may take longer than 45 seconds
to allow air to be purged from the gas line. If the
refrigerator has not been used for a long time or the LP
tanks have just been refilled, air may be trapped in the
supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1)
three or four times. If repeated attempts fail to start
the LP gas operation, check to make sure that the LP
gas supply tanks are not empty and all manual shutoff
valves in the lines are open. If the problem is still not
corrected, contact a service center for assistance.
NOTE: Do not continue to reset GAS operation if the
CHECK indicator lamp continues to be illuminated
after several tries.

5) If 120 volts AC becomes available while the CHECK
indicator lamp is on, the control system will switch to
120 volt AC operation. The CHECK lamp will not turn
off until the main power ON/OFF button is pressed to
the OFF then ON position.

6) In AUTO mode operation, the temperature is con­trolled by a single temperature setting.

C) MANUAL MODE

1) When operating in the MANUAL mode, the AUTO
mode indicator lampe (A) will be off, and the refrigera­tor will run continuously on the energy source se­lected by the control system.

2) The control system will automatically select between
AC and GAS operation with AC having priority over
GAS. If the control system is operating with AC
energy and it then becomes unavailable, the system

8

will automatically switch to GAS. As soon as AC

A

B

becomes available again, the control will switch back
to AC operation.

3) If the CHECK indicator lamp (B) illuminates, the
control has failed to ignite the burner on GAS. To reset
when the CHECK indicator lamp (B) is illuminated,
press the main power ON/OFF button (1) to the OFF
and then ON position.

4) The difference from AUTO mode is that in MANUAL
mode operation, the refrigerator will run without ther­mostat control on the energy source selected by the
control system.
NOTE: The food in the lower compartment may be
frozen if the refrigerator is left on in the MANUAL
mode.

D. STANDBY MODE OF OPERATION

This control system contains a feature that will continue to
operate the cooling system in the event of a failure of a major
operating component. If the control cannot read the tempera­ture sensor and operate at the preset tempertaure, then the
control will run the cooling unit continuously at the energy
source available. It operates like the MANUAL mode.

This should be considered when placing different types of
food in the refrigerator.

B. FROZEN FOOD STORAGE COMPARTMENT

Quick frozen soft fruits and ice cream should be placed in the
coldest part of the compartment which is on or just below the
freezer shelf. Frozen vegetables, may be stored in any part
of the compartment.

This compartment is not designed for deep or quick freezing
of food. Meat or fish, whether raw or prepared, can be stored
in the frozen food storage compartment provided they are
precooled first in the refrigerator. They can be stored about
three times longer in the frozen food compartment as
compared to the fresh food compartment. To prevent food
from drying out, keep it in covered dishes, containers, plastic
bags or wrapped in aluminum foil.

C. ICE MAKING

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.

The refrigerator will continue to operate in this mode indefi­nitely or until a new sensor is installed and the system is
reset.

E. TO SHUT OFF THE REFRIGERATOR

The refrigerator may be shut off while in any mode of
operation by pressing the main power ON/OFF button to the
UP (OFF) position.

4. HOW TO USE THE REFRIGERA­TOR

A. FOOD STORAGE COMPARTMENT

The food 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.

To release the ice cubes, seize the tray with both hands and
twist the tray. Cubes not required should be replaced in the
tray. Refill the tray with water and replace the tray on the
freezer shelf.
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 anticipated need for ice, but be sure to move the
thermostat back to normal setting, usually about mid-setting
when the ice is formed. Food in the lower compartment may
be frozen if the setting is left on "MANUAL" position.

C. DEFROSTING

Shut off the refrigerator by pressing the main power ON/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
reduced by filling the ice tray with hot water and placing it on
the freezer shelf.

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. They can create a leak in the ammonia
system.

9

When all frost is melted, dry the interior of the refrigerator with
a clean cloth. Replace all food and start the refrigerator by
pressing the ON/OFF button (1) to DOWN position.
NOTE: On these models the drip tray/cup is on the rear side
of the refrigerator. (See FIG. 1)

Put the plastic drain tube in a watertight bucket or container
(access through louvered service panel on the outside of the
vehicle). As the frost melts, the water will flow into the
container. When all the frost has melted wipe up the excess
moisture and empty the accumulated water from the bucket.
Replace the drain tube to its original position.

E.CLEANING

Cleaning the refrigerator is usually done after it is defrosted
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, 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.SHUT-OFF (STORAGE PROCEDURE)

Shut off the 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,
it should be emptied, defrosted, cleaned and the doors left
ajar. The ice tray should also be dried and kept outside the
cabinet.

G.CLIMATE CONTROL

During the summer months of high temperatures and
humidity, the metal frame between the freezer and fresh
food compartments may have water droplets forming. The
number of water droplets will increase if the vehicle isn't
air conditioned during these months.
This refrigerator comes standard with a 12 volt (DC)
climate control that 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
temperatures require it.

SECTION D.

MAINTENANCE & SERVICE

1.REFRIGERATOR REMOVAL

Before working on the refrigerator, make sure the AC voltage
and DC voltage leads are disconnected. Shut off the gas
supply. Disconnect the gas supply line. 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

Installation Instructions

.

2.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 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.

It is important to keep the refrigerator 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 appearance 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.

Section A, Item 1 to 12 of

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 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.Check the control system by connecting/disconnecting

120 volt AC power. Compare the operation with the
operation described in

NOTE: The following maintenance is required once or twice
a year, but should only be done by a qualified serviceman
who is familiar with LP gas systems and refrigerators.

D.The LP gas pressure should be checked and the main

regulator readjusted if pressure is incorrect. The correct
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).

E.Inspect the flue baffle. It should be reasonably clean and

.

free of soot. Heavy soot formation indicates improper
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. 6).

2)Disconnect or shut off the 12 volt power to the

refrigerator.

3)Turn manual shutoff valve to OFF. (See FIG. 6 & 12).

4)Remove cover from the burner housing. (See FIG . 6).

5)Disconnect the wire from the high voltage electrode.

6)Remove the burner mounting screws and remove the

burner assembly.

7)Remove the flue cap from top of flue tube and lift out

the wire and spiral baffle. Clean the flue from the top
using a flue brush. Blowing compressed air into the
flue will not properly clean soot and scale out of the
flue tube. Replace spiral baffle and flue cap.

8)Clean burner tube with a brush. Blow out burner with

compressed air.

9)Before removing burner jet, clean burner area of soot

and scale that fell out of flue tube. Remove the burner
jet. Soak the jet in wood alcohol and allow it to air dry.
Reinstall and tighten burner jet.

DO NOT use a wire or pin when cleaning the burner jet
