INSTRUCTIONS
IMPORTANCE OF LEVELING A
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.
The tubing in the evaporator section is
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 vehicle 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 $omfortable to live
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
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. 1.
This refrigerator is equipped with an Automatic Energy
Selector (AES) control system, which can automatically
select the most suitable energy source which is available, either 120 Volt AC, or LP gas operation. The system can be set by the user to be fully automatic, or if
desired, LP gas only. The refrigerator controls will work
down to 9.6 volt DC.
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 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.

LIMP MODE OF OPERATION
This control system contains a feature where it will continue to operate the cooling system in the event of a
failure of a major operating component. Two different
modes of operation can occur in this category
If for some reason the display module becomes non functional, the control system will revert to full automatic
operation selecting the best energy source available with

will be maintained at the MID position within normal tem-
perature tolerances. The power module will continually
attempt to reestablish operation of the display module.
The second limp mode of operation will execute when a
failure of the temperature sensing device or associated
electronic circuitry occurs. If this should occur, the control system will operate on the energy source selected
via the control panel. The cooling unit will run continu-
ously on the selected energy source. The refrigerator
will continue to operate in this mode indefinitely or until
a new sensor is installed and the system is reset.
To restart GAS operation, press the main power

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.

HOW TO USE THE REFRIGERATOR
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.
When the refrigerator is heavily loaded, it will take a
longer time to lower the temperature; therefore, to get
maximum efficiency
should be we-cooled prior to loading,The shelves should
not be covered with paper or plastic, and the food items
should be arranged so air can circulate freely.
Two door shelves are equipped with fingers. The fingers are designed to prevent large containers (l/Z-gal-
lon milk or juice) from shifting or spilling while traveling.
FROZEN FOOD STORAGE
COMPARTMENT
Quick frozen soft fruits and ice cream should be placed
in the coldest part of the compartment, which is on the
top freezer shelf. Frozen vegetables, may be stored in
any part of the compartment.
This compartment is not designed for deep or
freezing of food. Meat or fish, whether raw or prepared,
can be stored in the frozen food storage compartment
provided they are pre-cooled 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 orwrapped in aluminum foil.
Total Refrigerated Volume 12
ICE MAKING
Ice cubes can be made in the ice trays placed in the
freezer compartment. The trays should be filled with
water to within
making, the trays should be placed in direct contact with
the freezer 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 fresh food compartment
may be frozen if the setting is left on “COLDEST” posi-
tion.

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.
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 trays should also be dried and
kept outside the cabinet.
DO NOT store explosive substances in the refrigerator, such as cigarette lighter gas, petrol, ether or
the like.

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).
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:
Unplug the refrigerator power cord from the 120 volt

AC outlet. (See FIG. 3).

Disconnect or shut off the 12 volt power to the refrigerator.
Turn manual shutoff valve to OFF. (See FIG. 1).
Removecoverfrom
Disconnect the wire from the high voltage electrode.
Remove the burner mounting screws and remove the
burner assembly. (See FIG. 12).
Remove the wire and the 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
properly clean soot and scale out of the flue tube.
Replace the flue baffle.
Clean burner tube with a brush. Blow out burner with
compressed air.
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. Re-install and tighten burner jet.
NOTE: The color of the flame shall be clear blue
over the slots of the burner. (See FIG. 13).
