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

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 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.
Note! Any time the vehicle is parked for several hours with
the refrigerator operating, the vehicle must be levelled to
prevent this loss of cooling.
When the vehicle is moving, the levelling is not critical, as
the rolling and pitching movement of the vehicle will pass
to either side of level, keeping the liquid ammonia from ac-
cumulating in the evaporator tubing.
