SECTION C. OPERATING INSTRUCTIONS

1.IMPORTANCE OF LEVELING A REFRIGERATOR

In an absorption refrigerator system, ammonia is lique- fied in the finned condenser coil at the top of the refrige- rator. The liquid ammonia then flows into the evaporator (inside the freezer section) and is exposed to a circula- ting 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 slo- ped to provide a continuous movement of liquid ammo- nia 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 cir- culation of hydrogen and ammonia gas, or in severe cases, completely block it, resulting in a loss of cooling.

Remember to level the vehicle when stopping for more than an hour, otherwise the cooling unit could be perma- nently damaged due to overheating if it is left "ON".

When the vehicle is moving, the leveling is not critical as the rolling and pitching motion of the vehicle will pass to either side of level, keeping the liquid ammonia from accumulating in the evaporator tubing.
