INSTRUCTIONS
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 specific&y 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 $omfortable to live ~JI (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.
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.
This refrigerator is equipped with an Automatic Energy Selector (AES) control system, which can automatically select the most suitable energy source which is avail- able, either 120 Volt AC, or LP gas operation. The sys- tem can be set by the user to be fully automatic, or if desired, LP gas only. The refrigerator controls will work down to 9.6 volt DC.
Most LP gas appliances used in recreational ve- hicles are vented to the outside of the vehicle. 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.
FOR YOUR SAFETY, when refueling, shut off all LP gas appliances which are vented to the out- side.
