OPERATIONS & SYSTEMS
EVEREST EFI 980197 06/30/04 3-11
26. 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.
27. 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.
28. 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.
29. FLOW SIMULATOR 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. The valve is turned off by
rotating the knob clockwise and opened by
turning the knob counter clockwise.
30. PANEL LIGHT
This light is useful if the machine is used in a
poorly lit area or night use. It is helpful in
reading the instruments and gauges.
31. TEMPERATURE BALANCE ORIFICE
The temperature balance orifice helps to
balance and stabilize the solution temperature
within the system.
