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 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 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.

GAS 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.
OPERATING INSTRUCTIONS

E C
1. To start the refrigerator, turn knob A to position 0
(GAS).
2. Turn the thermostat knob B to position 4.
3. Push the button C in until it reaches the bottom -
and hold, push the button D for the piezo igniter
several times to light the burner. This can be
observed on the flame indicator E. When the flame
is on, the red indicator is in the green field. (ON).
4. After the gas is lit keep the button C pressed for 10
seconds. Release the button and check that the
RED indicator is in the GREEN field, (ON).
5. To shut off the refrigerator turn the knob A to "OFF"
position.
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.
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.
FORYOURSAFETY, when refueling, shut off all
LP gas appliances which are vented to the out-
side.
