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 for the very first time, the cooling cycle may require up
to 8 hours of running time before the cooling unit is fully operational to begin slowly
loading compartment with cold food from your cooler.
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 on LP Gas (Propane) & 110V (Electricity)
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.
