NOTE: Read and understand this section of
the manual entirely before proceeding.
This portion of the manual divides the unit up
into systems and describes how each system
works. Prior to proceeding into the operations
and maintenance sections of this manual it is
recommended that you acquire a basic
understanding of how the unit functions.
WATER RESERVOIR
The water reservoir is a pressurized vessel.
Cold water enters the console through the water
inlet connection located on the lower left corner
of the lower front panel. The water then flows
through the Inlet Pressure Regulator (where
incoming water pressure is reduced to 15 psi)
and into the water box.
WATER/HEATING SYSTEM
The water is pre-heated in the water box using
radiant heat generated by the vacuum blower,
engine and coil housing.
The water then flows to the water pump where
pressure is increased. From there it flows to the
heat exchanger where it travels through finned
tubing and is further heated by the vacuum
blower and engine exhaust.
The hot water then flows through the check
valve manifold that contains a strainer and a
check valve. At this point, the chemical
injection takes place.
The hot solution mixture of water and chemicals
then flows through the solution outlet manifold
to the cleaning tool. Solution pressure is
controlled by the Outlet Pressure Regulator.
