In an absorption refrigerant system ammonia is liquefied in the finned con-
denser 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.
The tubing in the evaporator section is specifically sloped to provide a con-
tinuous movement of liquid ammonia, flowing downward by gravity, through
this section. If the refrigerator is operated out-of-level when the vehicle is not
moving, liquid ammonia will accumulate in portions 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.
Any time the vehicle is parked for several hours with the refrigerator operating
the vehicle should be leveled to prevent this loss of cooling. The vehicle needs
to be leveled only so it is
comfortable to live in (no noticeable sloping of floor
or walls).
When the vehicle is moving the leveling is not critical, as the rolling and pitching
movement of the vehicle will pass to either side of level, keeping the liquid
ammonia from accumulating in the evaporator tubing.
OPERATION
The refrigerator requires 12-volt current to operate its electronic board even if
running on LP or 110-volt modes. The 12-volt is used to power the circuit board
that directs the refrigerator functions. When running in a mode such as LP, it
means the heat source, by far the largest power requirement; to evaporate the
ammonia is being provided by an LP Gas burner.
The International 16 Ft. Model is equipped with a fan inside the exterior
refrigerator compartment. This fan pulls ambient temperature air across the
condensation coils on the backside of the refrigerator to aid in the cooling. A
“Fan Switch” is located inside the the exterior refrigerator compartment on the
forward panel. You may desire to turn the fan off when using you patio due to
