General Operating Instructions
Importance of Leveling a Refrigerator
The refrigerator must be adjusted to a vertical position in both directions. In an
absorption refrigeration 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 circulating flow of hydrogen gas, which
causes the ammonia to evaporate, creating a cold condition in the freezer.
When starting this refrigerator, the cooling cycle may require up to four hours of
running time to begin cooling before the cooling unit is fully operational, you can then
begin slowly loading the compartment.
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 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. Warranty will not
cover recharge/rebuild if caused by not running the fridge level.
This refrigerator operates only on LP Gas (Propane)
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.We
suggest first turning off gas at the control panel, then the tank,this will reduce an air trap in the gas line.
Gas Operation
1.
To start the refrigerator, turn the thermostat knob
B
to maximum setting (fully
clockwise).
2.
Turn button
C
to Gas “on” position, then push same button in and hold.
3.
Immediately push button
A
repeatedly for the piezo igniter to light the burner.
Continue to hold the
C
button until you see the flame at the burner head . This
can be observed looking thru the control panel area at the rear left corner . Hold in
the C button for 20 seconds then release pressure. Burner should remain on.
