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
freezer.
The tubing in the evaporator section is specifically
sloped to provide a continuous movement of liquid am-
monia, 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 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 system 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.
! WARNING
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
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.
WINTER STORAGE
If you plan to put the RV into winter storage, it should be
emptied, defrosted, cleaned and the doors left ajar.
The water to the ice maker should be shut off at the water
supply valve.
The ice maker should be drained to prevent component
damage and leaks.
How to drain the ice maker see page 11,
