OPERATION
14. TEMPERATURE CONTROL VALVE
This valve allow 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 cleaning hoses. This outlet has 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 tool.
18. EXHAUST

This quick connect allows the water supply hose
to be connected to the unit.

for vacuum hoses.
POSITION)
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.
CONTROL VALVE IN RUN)
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.
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.
