6. Optional Three Function Valve
The optional three function valve injection assembly provides the following three functions in
one.
Anti-siphon
feature allows metering of liquids “down hill” or into the suction side of a circulating
pump. It provides protection against an accidental application of suction pressure at the injection
point. The Teflon coated diaphragm provides a positive anti-siphon action.
Back pressure
function permits metering into atmospheric discharge without over pumping.
Line check
to permit the removal of discharge tubing without release of system fluid.
7. Priming / Degassing Valve Connection
Connect the clear poly tubing to the outlet of the bleed or priming valve. Position the free end of
this tube in the chemical container, above the fluid level. This unique valve allows for the release
of trapped air from the pump head when opened. Open valve all the way to quickly prime the
pump, close it when primed. The valve can work as a degassing valve when the valve is left open
approximately 1 turn.
V. Start-Up
A. Front Panel Description
All Model R pumps come with the following standard panel features:
• 1x16-backlit LCD display
• On/Off power indicator light
• Pulse or Stroke indicator light
• Up and Down arrow keys for setting adjustments
• ENTER key to save desired adjustments
• MENU key to enter and exit pump set-up
B. Run Mode Explanation
The readout will display one of two modes, Run mode or Set-up mode. Run mode is displayed only
while the pump is on during normal operation.The screen will display the current conductivity value
and indicate if it is calling for bleed. If conductivity functions are deactivated, the display will show the
pump speed setting. Use the UP and DOWN arrow keys to monitor the current speed and length as
well as timer settings when the pump is in RUN mode.
Pumps with control options can be forced into a priming for three minutes from the RUN mode by
pressing the ENTER key. Pressing the ENTER key again during the priming cycle will put the pump
back into the normal RUN mode. All adjustments
for stroke frequency, optional timer settings and
password information are made from the Set up mode.
