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.
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. A backup
wrench must be used when tightening gas supply
fitting. All completed connections should be checked for
leaks with a noncorrosive leak detector.
OPERATING INSTRUCTIONS
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
11 inches water column.
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 1/2 psig, the appliance must be isolated
from the gas supply piping system 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.
TESTING LP GAS SAFETY
SHUTOFF
The gas safety shut-off must be tested after the
refrigerator is connected to the LP gas supply.
To test the gas safety shut-off, proceed as follows:
1.
2.
3.
4.
5.
6.
7.
Start the refrigerator according to the instructions for
Gas Operation, section “Operation Instructions”.
Check that the gas flame is lit. This can be observed
through the reflector (E).
Close the gas valve by turning the knob (A) back to
“OFF” position.
Wait for one minute.
Remove burner cover plate, one screw at the burner.
Open the gas valve by turning the knob (A) to position
“GAS” without pushing the buttons (C)and (D). Apply
a non-corrosive commercial bubble solution to the
burner jet.
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.
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 the burner jet. Replace burner cover plate
and turn the knob (A) back to “OFF’. Start the refrigerator by following the instructions for Gas Operation,
section “Operation Instructions”. Normal operation of
the burner should return. Allow the burner to operate
for a minimum of 5 minutes.
ELECTRICAL CONNECTION
120 Volt AC Connection
The refrigerator is equipped with a three-prong (grounding) plug for your 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 cord should be
routed to avoid direct contact with the burner cover, flue
cover or any other components that could damage the
cord insulation.
IMPORTANCE OF LEVELING
A REFRIGERATOR
In an absorption refrigerator system, ammonia is liquefied 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.
When starting this refrigerator for the very first time, the
cooling cycle may require up to four hours of running
time before the cooling unit is fully operational.
The tubing in the evaporator section is specifically
sloped 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, 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.
The refrigerator must be adjusted to a vertical position
in both directions.
Use the feet on the refrigerator to adjust its position.
CONTROLS
FIG.3.
The refrigerator can be run on either 120 volt AC or LP
gas. Changing between these modes of operation is
carried out by means of control buttons positioned as
shown in fig. 3.
The energy selector (A) can be set at either “ELEC” (120
volt AC), “GAS” (LP gas) or “OFF”.
The refrigerator temperature is controlled by a thermostat (6). Please note that the thermostat has no “off”
position.
The refrigerator is fitted with a safety device which
automatically shuts off the supply of gas if the flame goes
out. The safety device can be opened manually by
depressing knob (C).
The piezoelectric igniter discharges sparks over the
burner when the button (D) is pushed.
In the flame viewer (E) you can see a blue light when the
flame is alight.
GAS OPERATION
The position numbers refers to FIG. 3.
1. To start the refrigerator, turn the knob “A” to the
“GAS” position.
2. Turn the thermostat knob "B" to setting 4.
3. Push button "C" to stop - and hold, push button “D”
for the piezo igniter several times to light the burner.
This can be observed through the flame view port “E”.
4. After the flame lights, continue to hold the button “C”
for an additional ten (10) seconds. Release the button
“C” and check the flame view port “E” to make sure
the burner does not go out. If the burner goes out,
repeat the lighting procedure Steps 1 through 4.
5. To shut off the refrigerator, turn the knob “A” to the
“OFF” position.
NOTE: After changing an LP tank, or after a long shut
off period, the gas line is likely to be filled with air. You
may have to repeat the lighting procedure several times
to purge the air out of the gas lines.
ELECTRIC OPERATION
The position numbers refers to FIG. 3.
1. Check to be sure the power cord is properly connected to the power supply.
2. Turn knob “A” to the position marked “ELEC” for 120
volt AC operation.
3. Turn the thermostat knob "B" to setting 4.
4. To shut off the refrigerator, turn the knob “A” to the
“OFF” position.
THERMOSTAT
The refrigerator is equipped with a thermostat that can
be adjusted by turning knob “B” to different setting to
maintain the desired cabinet temperature. See FIG. 3.
1. “OFF” Setting of the Thermostat: In gas operation,
the thermostat closes its main valve and the burner
runs continuously at the bypass rate or pilot. In
electric operation, the contacts in the thermostat are
open and the heating element is off.
2. “MAX” Setting of the Thermostat: In gas operation,
the thermostat allows the burner to remain on high
flame continuously. In electric operation, the heating
element is “ON” continuously.
3. The thermostat can be adjusted between “MAX” and
“OFF” to obtain the desired cabinet temperature. The
closer the knob is to “MAX”, the colder the cabinet
temperature. The closer the knob is to “OFF”, the
warmer the cabinet temperature.
When the thermostat reaches the set temperature, it will
cut the burner back to bypass or, in electric operation,
shut off the heating element.
The setting of the thermostat is not critical, but we
recommend it be adjusted to maintain a dry frost on the
cooling fins. Adjust the thermostat knob closer to “MAX”
when the outside temperature becomes warm.
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.
FROZEN FOOD STORAGE
COMPARTMENT
Quick frozen soft fruits and ice cream should be placed
in the coldest part of the compartment which is at the
bottom of the aluminum liner. 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.
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" (5 mm) from the top.
For faster ice making, the tray should be placed in direct
contact with the bottom of the freezer compartment.
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
in the freezer compartment.
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 turn
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 refrigerator is left on
“MAX” position.
DEFROSTING
Frost will gradually accumulate on the refrigerating surfaces. It must not be allowed to grow too thick as it acts
as an insulator and adversely affects refrigerator performance.
Check the formation of frost regularly every week and
when it gets about 3 mm thick, defrost the refrigerator.
Shut off the refrigerator by turning knob “A” to “OFF”
position. Empty the refrigerator, leaving the cabinet and
freezer doors open. Defrosting time can be reduced by
filling the ice tray with hot water and placing it in the
freezer compartment.
MAINTENANCE & SERVICE
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 compartment.
They can create a leak in the ammonia system.
The defrost water runs from a collector channel to a drip
tray/cup at the rear of the refrigerator where it normally
evaporates.
If heavy frost built up on the freezer plate and the cooling
fins, and a lot of defrost water, move the plastic drain
tube in to a watertight bucket or container.
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.
Defrost water in the freezer compartment should be
wiped up with a clean cloth.
When all the frost is melted, dry the interior of the
refrigerator with a clean cloth. Replace all food and set
the thermostat to “MAX” for a few hours. Then reset the
thermostat to its normal position.
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, gasket,
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
To shut off the refrigerator, turn knob “A” to “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.
NOTE: To avoid running down the batteries to the interior
light during defrosting and storage periods, use a tape
to close the light switch or remove the lamp bulb. The
batteries can also be removed from the battery box at
the rear of the refrigerator.
DO NOT store explosive substances in the refrigerator, such as cigarette lighter gas, petrol, ether or
the like.
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 the refrigerator, make sure the AC
voltage leads are disconnected. Shut off the gas
supply. Disconnect the gas supply line at the rear of
the refrigerator. Always use a back up wrench when
loosening and tightening this connection. Cap the
gas supply line and remove the refrigerator.
Replacement is the reverse of removal. Check all
connections for gas leaks.
Refer to section INSTALLATION, page 2 and 3.
2.
A.
PERIODIC MAINTENANCE
To keep your refrigerator operating efficiently and
safely, periodic inspection and cleaning of several
components is recommended once or twice a year.
It is important to keep the area at the back of the
refrigerator clean. 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.
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.
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 GAS SYSTEM AND
REFRIGERATORS.
DO NOT use a flame to check for gas leaks.
C. Check burner flame for proper appearance. The
flame should be light blue with no yellow at the tip.

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. 5).
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:
Unplug the refrigerator power cord from the 120 volt
AC outlet.
Turn the knob “A” to “OFF” position.
Remove cover from the burner housing.
Disconnect the wire from the high voltage electrode.
Remove the burner mounting screw and remove the
burner assembly.
Remove the wire and 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.
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.

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).
10. Be sure to reconnect the wire to high voltage electrode. Check the electrode for proper location and
gap. (See FIG. 6).

11. The gas fittings on the refrigerator need to be
checked for leaks. Turn the knob “A” to position
“GAS”. Apply a non-corrosive bubble solution to the
fitting and observe for leaks. The safety valve will not
allow gas pressure to any connections between it and
the burner jet. These fittings must be checked before
burner is lighted.
The safety shut-off must be manually depressed to allow gas pressure to flow to the
burner jet. Be sure to apply the leak check solution before depressing the safety shut-off. DO
NOT allow any open flame, sparks, smoking,
etc., in the area of the test. DO NOT depress
safety shut-off for over 30 seconds.
12 Allow 10 minutes for the LP gas to leave the burner
area. Light the burner according to the Operating
Instructions, section Gas Operation. Allow burner to
run 5 minutes.
Connect
120 volt power cord to the outlet.
