cold condition in the freezer.
When starting this refrigerator for the very rst
time, the cooling cycle may require up to four
hours of running time before the cooling unit is
fully operational.

erator operating, the vehicle should be leveled to prevent this
loss of cooling.
If the refrigerator is operated when it is not level and the
vehicle is not moving, liquid ammonia will accumulate in sec-
tions 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.
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.
AUTOMATIC ENERGY SELECTOR SYSTEM
The refrigerator is equipped with an automatic energy selector
system. The user turns the refrigerator on and then, the refriger-
ator automatically selects the most suitable energy source avail-
