General Operating Instructions
Importance of Levelling a Refrigerator
The refrigerator must be adjusted to a horizontal 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 8 hours of
running time to begin cooling before the unit is fully operational. After 8 hours you
can
slowly
begin 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.
