DE = Dead End.
You need to calibrate your variflow:
Adjustment Procedure:
With the Varistream VSD6 switched on - press up and down arrows simultaneously for three seconds to display the pressure setting.
Release the up and down arrows for 1-2 seconds - then press up and down arrows simulateously for three seconds and the digit will flash.
Use the up and down arrows to select the figure you require (you will need to increase the number). If the pump is shutting off at too low a pressure, select a higher number, if the pump is not switching off - select a lower number. It is recommended that you change by one increment at a time to avoid large swings in shut off pressure.
Once the desired number is displayed switch of the varistream.
When you switch the varistream on again, it will have accepted your new setting.
(The above was taken from the instructions that came from mine; the stuff in brackets was my addition.)
Hope this 'elps.
