has five major systems:
the air system, the water system, the heater system, and the electronic con-
trol system. These systems provide a supply of pressurized, temperature-
After the system is operating, the operator is required to
periodically monitor the output water temperature and fuel supplies.
No external power is required to operate the system. Only a source
of water and fuel is needed.
Decontamination may be conducted in the follow-
ing three ways:
(1) Decontamination of material and equipment using the cleaning
(2) Decontamination of personnel using the showers.
(3) Decontamination using the injector and decontaminating agents.
ENGINE PRINCIPLES OF OPERATION.
The engine is a one-cylinder, 2-cycle, air-cooled, power source that
develops 7.3 horsepower at 4250 rpm.
A centrifugal clutch drives the combus-
tion air fan, the water pump, and the heater fuel pump. The clutch begins to
drive the fan, water pump, and fuel pump when the engine speed exceeds 2700
A diaphragm fuel pump operates on pulsating crankcase pressure to
supply fuel to the engine carburetor.
The engine has a built-in generator. The generator
at 17 watts to power the electronic control system.
