OPERATING
INSTRUCTIONS
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
f r e e z e r .
The tubing in the evaporator section is
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 ve-
hicle is not moving, liquid ammonia will accumulate in
sections of the evaporator tubing. This will slow the cir-
culation 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
to live (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
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 an Automatic Energy
Selector (AES) control system, which can automatically
select the most suitable energy source which is avail-
able, either 120 Volt AC, or LP gas operation. The sys-
tem can be set by the user to be fully automatic, or if
desired, LP gas only. The refrigerator controls will work
down to 9.6 volt DC.
Most LP gas appliances used in recreational ve-
hicles are vented to the outside of the vehicle.
When parked close to a gasoline pump, it is pos-
sible that the gasoline fumes could enter this
type of appliance and ignite from the burner
flame, CAUSING A FIRE OR AN EXPLOSION.
FOR YOUR SAFETY, when refueling, shut off all
LP gas appliances which are vented to the out-
side.
