A.Start the refrigerator according to the instructions, and
switch to gas mode. See "Section C. Operation Instruc-
tions."
B.Check that the gas flame is lit.
C.Close the manual shutoff valve at the back of the
refrigerator. (See FIG. 6)
D.Wait for one minute. The check indicator lamp (B) should
now be lit and the gas mode indicator lamp should be off.
E.Remove cover (see FIG. 6) and open the manual gas
valve. Apply a noncorrosive commercial bubble solution
to burner jet (see FIG. 6).
switch OFF and back ON. (See "Section C. Operation
Instructions, Item 2. Control Panel"). Normal operation of
the burner should return. Allow the burner to operate for
a minimum of 5 minutes.
10.120 VOLT AC 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 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.
! WARNING
DO NOT USE A FLAME
TO CHECK FOR GAS LEAKS.
F.No bubbles should appear at the opening of the burner jet.
The presence of bubbles indicates a defective gas safety
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

11. 12 VOLT DC CONNECTION
This refrigerator model is not designed for 12 volt DC
operation of the cooling system; however, 12 volt DC must
be supplied to the refrigerator to operate the controls. Use a
minimum of a 14 gauge wire between the battery and
refrigerator to supply the control voltage. The connection is
made to the positive (+) and negative (–) terminals of the
terminal block on back of refrigerator. (See FIG. 6) The 12
volt DC supply circuit must be fused, and the maximum
fuse size is 5 amps.
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.
Clean Direct Current (DC) power is mandatory for hightech circuits to operate as designed. The sources for DC
power are a battery and a converter.
A battery will provide straight line DC power, but extended operation will require recharging of the battery
by the converter or the alternator.
The converter and alternator produces DC power by a
series of diodes that rectify alternating current to DC. A
battery or capacitors can be used to clean up the AC
ripple that is present after AC voltage has been rectified.

SECTION C. OPERATING INSTRUCTIONS
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.
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.

3. START-UP INSTRUCTIONS
Before starting the 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. 6.
This refrigerator is equipped with a control system, which
can automatically select the most suitable energy source
which is available, either 120 Volt AC or LP gas operation.
The refrigerator can be operated in either the AUTO mode
(thermostat factory preset below the safe food storage
temperature) or MANUAL mode (continuous operation - no
thermostat control).
NOTE: Under certain cool weather conditions, the food in the
lower portion of the fresh food compartment may freeze if
operated for an extended period of time on the MANUAL
mode.
A. A 12 volt DC supply must be available for the electronic
control to function. The refrigerator will work down to 9.6
volt DC.
B. Press the main power ON/OFF button (1) to the
DOWN position.
B. In AUTO mode operation, the temperature is controlled
by a single temperature setting, on the energy source
selected by the control system. (See Auto Mode)
C. In MANUAL mode operation, the refrigerator will run
continuously on the energy source selected by the
control system. (See Manual Mode)
NOTE: The food in the lower compartment may be frozen if
the refrigerator is left on MANUAL mode.
D. 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. This shuts off all DC power to the
refrigerator, including the interior light.
4. DESCRIPTION OF OPERATING
MODES
A. AUTO MODE
Press the AUTO/MANUAL mode selector button (2) to the
DOWN position. The AUTO mode indicator lamp (A) will
illuminate.
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 on 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.
9
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 the ON
position. The control system will attempt a new 45 second
ignition sequence.
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 of 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 3
or 4 tries.
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.
In AUTO mode operation, the temperature is controlled by
a single temperature setting.
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.
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 control panel is set in the
MANUAL position. It is a good idea to do this a few hours
before the anticipated need for ice, but be sure to set the
control back to AUTO setting when the ice is formed. Food
in the lower compartment may be frozen if the setting is left
in the MANUAL position.
B.MANUAL MODE
When operating in the MANUAL mode, the AUTO mode
indicator lamp (A) will be off, and the refrigerator will run
continuously on the energy source selected by the control
system.
5.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.
This should be considered when placing different types of
food in the refrigerator.
D. 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.
10
When all frost is melted, dry the interior of the refrigerator with
a clean cloth. Replace all food and turn the refrigerator back
on.
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, 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.SHUT-OFF (STORAGE PROCEDURE)
Shut off the refrigerator by pressing the main power ON/OFF
button to the UP (OFF) position. (See FIG. 10)
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.
! WARNING
DO NOT store explosive substances in the refrigerator,
such as gasoline and other flammable vapors or liquids.
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 the climate control on, you position the switch ("C",
Figure 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.
! CAUTION
THE CLIMATE CONTROL WILL DRAW 12 VOLT DC
POWER CONTINUOUSLY WHEN IN THE "ON" POSITION. IT SHOULD BE TURNED "OFF" WHEN A CHARGING SOURCE IS NOT AVAILABLE. IT WILL QUICKLY
DRAIN THE CHARGE FROM A BATTERY.

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 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.
10)Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket. Check
to make sure slots are centered under the flue tube
and the thermocouple is positioned properly (tip of
thermocouple extends over two slots of burner).
11)Be sure to reconnect the wire to high voltage elec-
trode. Check the electrode for proper location and
gap. (See FIG. 13).

12)Turn on manual gas shutoff valve and check all
fittings for leaks.
13)Connect 120 volt power cord to the outlet and
reconnect or turn on the 12 volt DC power.
14)Check LP gas safety shutoff. See
lation, Item 9. Testing LP Gas Safety Shutoff
