15. VACUUM INLETS
The vacuum inlets serve as connecting point for
vacuum hoses.
16. SOLUTION OUTLETS
The solution outlets are the connecting point for
the high pressure cleaning hoses. These
outlets are quick disconnects that allow hoses to
be plugged into the unit.
17. SOLUTION SCREEN
The solution screen is located on the front of the
machine. The function of this screen is to trap
foreign particles from exiting the machine and
plugging the orifices of the cleaning tools. This
screen is part of the machine maintenance
cleaning.
18. CHEMICAL CHECK VALVE
The chemical check valve allows chemicals to
enter the system and travel in a singular
direction to the wand. The chemical check valve
prevents chemicals from traveling up-stream into
the solution system of the unit.
19. WASTE OUTLET
This valve allows the waste tank to be emptied.
Turning clockwise opens the valve.
20. WASTE PUMPOUT
This auxiliary pump serves to empty the waste
collection tank automatically. A float located
inside the tank automatically turns off and on
when the solution level reaches certain points.
21. WARM WATER OUTLET
The warm water outlet allows the cleaning
technician to drain hot water from the water box
for mixing chemical.
Water from this valve is hot.
22. WATER INLET
This quick connect allows the water supply hose
to be connected to the unit.
23. PRESSURE REGULATOR
This pressure regulating valve allows the water
pressure circuit to be adjusted by turning the
handle clockwise the pressure will increase, by
turning counter clockwise the pressure will
decrease.
24. FLOW METER
The flow meter is a gauge to indicate how much
liquid chemical is being introduced in the water
system. The quantity can be increased by
turning the chemical flow knob counter
clockwise.
25. CHEMICAL PRIME CONTROL VALVE
This valve allows the chemical to circulate
through the chemical system with little or no
restriction. It also purges out air that may be
trapped in the lines and cavities of the chemical
pump. By turning the valve clockwise the
injection system is enabled.
26. CHEMICAL METERING VALVE
The chemical metering valve regulates the
amount of chemical that is injected into the
system. Clockwise rotation of the knob closes
the valve. Counter clockwise rotation opens the
valve, allowing more chemical to enter the
system.
