Operations
14. SOLUTION TEMPERATURE CONTROL
VALVE
This valve allows the operator to control the
solution temperature by bypassing hot water to the
waste tank, for low temperature cleaning such as
upholstery. Turning the valve counter clockwise
opens the valve. Turning clockwise closes the
valve and has the effect of stopping water from
bypassing.
15. 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 upstream into the solution
system of the unit.
16. SOLUTION OUTLET
The solution outlet is the connecting point for the
high pressure solution hoses. This outlet is a quick
disconnect that allows 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. EXHAUST
Exhaust fumes contain carbon monoxide which is
an odorless and deadly poison that can cause
severe injury or fatality. DO NOT run this unit in an
enclosed area. DO NOT operate this unit where
the exhaust may enter any building doorway,
window, vent, or opening of any type.
19. WATER INLET
This quick connect allows the water supply hose to
be connected to the unit.
20. VACUUM INLETS
The vacuum inlets serve as connecting points for
vacuum hoses.
21. 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.
22. 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.
23. 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.
