4-14.14.3 Freezer Section
The freezer section offers 58% more than ever before.
The top shelf can be removed and stored on the side to provide space for tall items in
the upper section of the freezer.
Optional ice maker.
Halogen light illuminates the area. Never before has there been an absorption
refrigerator with a light in the freezer.
Three wire bins that tilt out. This allows for full use of the space between the bins.
Two additional door bins to house smaller items.
Two clear view baskets with individual side tracks. This provides the ease of loading
and removing items without complete removal of the heavy baskets when full.

4-14.14.3 Refrigerator Control Panel
The tubing in the evaporator section is specifi cally sloped to provide a continuous movement of liquid ammonia, fl owing
downward by gravity through this section. If the refrigerator is operated when it is not level and the coach 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 coach is parked for several hours with the refrigerator operating, the coach should be leveled to prevent this loss
of cooling. The coach needs to be leveled only so it is comfortable to live in (no noticeable sloping of fl oor or walls).
When the coach is moving, the leveling is not critical, as the rolling and pitching movement of the coach 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 ).
4-14.14.4 Operating
Instructions
IMPORTANCE OF LEVELING A
REFRIGERATOR
In an absorption refrigerator system, ammonia
is liquefi ed in the fi nned condenser coil at the
top rear of the refrigerator. The liquid ammonia
then fl ows into the evaporator (inside the freezer
section) and is exposed to a circulating fl ow
of hydrogen gas, which causes the ammonia
to evaporate, creating a cold condition in the
freezer.
When starting this refrigerator for the very fi rst
time, the cooling cycle may require up to four
hours of running time before the cooling unit is
fully operational.
