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 individu-
al 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 de-
fective 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 refrig-
erator 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 (ground-
ing) 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 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.
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 am-
monia, 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 thermo-
stat (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.
