Installation Guide
Free-Standing Model for Floor Installation (ONLY)
The room must be well ventilated and not used in a bedroom. Further the room should have a window
(which can be opened) or a door to the outside.
For best performance at high ambient temperatures there must be a free air circulation over the cooling
unit at the rear of the refrigerator. Ensure that there is a free space of at least 4” inches (100 mm)
above the refrigerator and that the exhaust opening on the top of the refrigerator is not covered in any
way.
Do not place the refrigerator in a space where air circulation is restricted. A clearance of at least 1-inch
(25 mm) should be left between the rear and sides of the refrigerator and the surrounding walls.
This freestanding refrigerator requires accessibility to the rear for servicing the appliance. Accessibility
can be obtained by using a certified Flexible Metal Gas Connector. which would allow the refrigerator to
be moved without disrupting the gas supply. Use the feet on the refrigerator to adjust its position.
NOTE: For optimal performance the refrigerator must be level.
Clearances
Minimum clearances in inches to combustible materials are:
Top:
3.96” (Min 100mm)
Side:
1”
Rear/Back:
1”
Bottom: The feet must be in place to
ensure free air circulation.
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.
The gas supply system must incorporate a pressure regulator to maintain a supply pressure of 11
inches water column.
When testing the gas supply system at test pressures in excess of 1/2 psi, 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 psi, 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.
EXPLOSION HAZARD
Never use an open flame to check for gas
leaks. Failure to heed this warning could
cause an explosion resulting in death or
severe personal injury.

Installation Guide
Testing LP Gas Safety Shutoff
The gas safety shutoff must be tested after the refrigerator is connected to the LP gas supply.
To test the gas safety shutoff, proceed as follows:
1. Start the refrigerator according to the instructions for Gas Operation; section “Operation
Instructions”. See Figure #1
2. Check that the gas flame is lit. This can be observed through the flame indicator (B).
3. Close the gas valve by turning the knob (E) back to “OFF” position.
4. Wait for one minute.
5. Remove burner cover plate, one screw at the burner. Open the gas valve by turning the
knob (E) to position “GAS” without pushing the buttons (A) and (C). Apply a non-corrosive
commercial bubble solution to the burner jet.
6. 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.
7. 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.
8. Replace the burner cover plate and turn the knob (E) back to “OFF”.
9. Start the refrigerator by following the instructions for Gas Operation, section “Operation
Instructions”.
10. Normal operation of the burner should return. Allow the burner to operate for a minimum of
5 minutes.
Electrical Connection
120 V 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 receptacles. 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.
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 backup 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.

Operating Instructions
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
The refrigerator can be run on either 120volt AC or LP gas. Changing between these modes of
operation is carried out by means of control buttons positioned as shown in Figure #1.
Figure #1
The energy selector (E) can be set at “ELEC” (120volt AC), “GAS” (LP gas) or “OFF”. The refrigerator
temperature is controlled by a thermostat (D). 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 (A) is pushed. In the flame viewer (B) you can see
a blue light when the flame is alight.

Operating Instructions
Gas Operation
1. To start the refrigerator, turn the knob (E) to the “GAS” position.
2. Turn the thermostat knob (D) to setting.
3. Push button (C) in until it bottoms out - and hold. While holding button (C), push button (A)
for the piezo igniter several times to light the burner. This can be observed through the flame
view port (F).
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 (B) to make sure the burner does not
go out. If the burner goes out, repeat the lighting procedure Steps 1 through.
5. To shut off the refrigerator, turn the knob (E) 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 (110V)
1. Check to be sure that the power cord is properly connected to the power supply.
2. Turn knob (E) to the position marked “ELEC” for 120volt AC operation.
3. Turn the thermostat knob (D) to setting.
4. To shut off the refrigerator, turn the knob (E) to the “OFF” position.
Thermostat
The refrigerator is equipped with a thermostat that can be adjusted by turning knob (D) to different
setting to maintain the desired refrigerator temperature.
•“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.
•“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.
•The thermostat can be adjusted between “MAX” and “OFF” to obtain the desired refrigerator
temperature. The closer the knob is to “MAX”, the colder the refrigerator temperature. The
closer the knob is to “OFF”, the warmer the refrigerator 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.
EXPLOSION HAZARD
Never store explosive substances in the
refrigerator, such as cigarette lighter
fuel, gasoline, ether or the like. Failure to
heed this warning could cause an
explosion resulting in death or severe
personal injury.

Operating Instructions
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.

Operating Instructions
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 1/8” (mm) thick, defrost the
refrigerator.
Shut off the refrigerator by turning knob (E) to “OFF” position. Empty the refrigerator, leaving the
refrigerator and freezer doors open. Filling the ice tray with hot water and placing it in the freezer
compartment can reduce defrosting time. The defrost water runs from a collector channel to a drip tray
or 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.
Do not use:
•A knife or an ice pick, or other sharp tools to
remove frost from the freezer shelves. It can
create a leak in the ammonia system.
•A hot air blower. Permanent damage could
result from warping the metal or plastic parts.
