In absorption refrigerant system ammonia is liquefied 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 specifically sloped to provide a continuous movement of liquid ammonia, flowing downward by gravity, through this section. If the refrigerator is operated out-of-level when the vehicle is not moving, liquid ammonia will accumulate in portions 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 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 comfortable to live in (no noticeable sloping of floor or walls).

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

OPERATION

 

The refrigerator requires 12-volt current to operate even if running on LP or 110 volt

 

modes. The 12-volt is used to power the circuit board that directs the refrigerator

 

functions. When running in a mode such as LP, it means the heat source, by far the

 

largest power requirement; to evaporate the ammonia is being provided by an LP

 

Gas burner.

 

Safari 16, 19, 20, & 22 ft. Models are equipped with a fan inside the exterior refrigerator

 

compartment. This fan pulls ambient temperature air across the condensation coils on

 

the backside of the refrigerator to aid in the cooling. A “Fan Switch” is located inside

 

the main door on the panel in front of the refrigerator. You may desire to turn the fan

 

off when using you patio due to its noise. The fan is thermostatically controlled when

 

the switch is on.

 

The fan does increase the cooling efficiency of the refrigerator; therefore Airstream

 

recommends leaving the switch on whenever the patio is not in use. Please note that

 

turning the fan off during hot, humid weather conditions may substantially affect the

 

cooling capacity of the refrigerator.

 

Warning: Most LP gas appliances used in recreational vehicles are vented

H

to the outside of the vehicle. When parked close to a gasoline pump, it is possible

that gasoline fumes could enter this type of appliance and ignite the burner flame,

CAUSING A FIRE OR AN EXPLOSION.
