Operations
5. Solution Outlets
The solution outlets are the connecting point for the
high pressure solution hoses. These outlets are quick
disconnects that allow hoses to be plugged into the
unit.
6. 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.
7. 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.
8. Temperature Balance Orifice Shutoff Valve
The temperature balance orifice shutoff valve allows
the operator to increase solution temperature during
two wand operation. This should only be closed during
two wand operation.
9. Temperature Balance Orifice
The temperature balance orifice helps to balance and
stabilize the solution temperature within the system.
10. Waste Outlet
This valve allows the waste tank to be emptied.
Turning counter-clockwise opens the valve.
11. Waste Pumpout Outlet
This is a hose connection point for the waste pumpout
pump, which serves to empty the waste collection tank
automatically. A float located inside the tank automati-
cally turns off and on when the waste water level
reaches certain points.
12. 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.
13. Water Inlet
This quick connect allows the water supply hose to be
connected to the unit.
14. Solution Pressure Regulator
The pressure regulator sets the pressure of the solution
system. This spring loaded valve can be adjusted up or
down. The pressure is increased by turning the valve
clockwise, or reduced by turning the valve counter-
clockwise. (This valve must be maintained in accor-
dance with this manuals maintenance table.)
15. 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.
16. 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. Counterclockwise
rotation opens the valve, allowing more chemical to
enter the system.
17. 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.
18. Flow Setup Valve
This valve allows solution to move through the machine
and chemical to be injected simulating the cleaning
process. This allows the operator to set the chemical
flow level without connecting tools to the machine. It is
also useful in troubleshooting.
