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
To test the gas safety
1.Start the refrigerator according to the instructions for Gas Operation, section “Operation Instructions”.
2.Check that the gas flame is lit. This can be observed through the reflector (E).
3.Close the gas valve by turning the knob (A) 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 (A) to position “GAS” without pushing the buttons (C)and(D). Apply a
6.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.
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. 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.

OPERATING 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.
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.
