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.
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 it is not level
and the vehicle is not moving, 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.
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 motion of the vehicle will pass
to either side of level - keeping the liquid ammonia from
accumulating in the evaporator tubing.

OPERATION
Before starting the refrigerator, check that all the manual
gas valves are in the ON position. DO NOT forget the
manual shutoff valve on the rear of the refrigerator see
FIG. 1.
This refrigerator is equipped with a semi Automatic
Energy Selector (AMES) control system, which can
automatically select the most suitable energy source
which is available, either AC or LP gas operation, or if
desired, LP gas only.
The refrigerator controls will work down to 9.6 volt DC.
Most LP gas appliances used in recreational
vehicles are vented to the outside of the
vehicle. When parked close to a gasoline pump,
it is possible that the gasoline fumes could
enter this type of appliance and ignite from the
burner flame, CAUSING A FIRE OR AN EXPLO-
SION.
FOR YOUR SAFETY, when refueling, shut off all
LP gas appliances which are vented to the out-
side.
