  • Page 44: Operation (Semi-Automatic Controller)

    3.7 Operation (Semi-Automatic Controller) The diaphragm valve style face piping kits are designed for simple operation and maintenance. Backwashing is accomplished by turning a single knob to actuate the diaphragm valves. The automatic controller can be set up to backwash automatically dependant on certain chosen parameters, as well manually if required (refer to automatic controller manual for more information).
  • Page 45 The semi-automatic controller consists of a single gauge panel with gauges to measure influent and effluent pressures, water pressure supplied to the multiport valve, and the multiport valve knob, which is used to actuate the valves. The influent and effluent pressure gauges show the water pressure coming into and out of the filter system.
  • Page 46 STEP 2: Verify that multiport pressure gauge returns to normal pressure. When actuating the valves the pressure to the multiport valve drops. When the valves become actuated the pressure gauge will begin to rise, and should return to its preset value (35 psi minimum). At this point, the valves are fully actuated. If the pressure does not return to its initial value, please consult the troubleshooting section of this manual.
  • Page 47 Once system piping and proper valve installation is complete. Including hydraulic lines for valve activation. Hydro test system*. This must be done prior to adding media, start pump, allow system to fill with water to (bleed out all air). Run system for several minutes while doing this inspect for leaks and any unnecessary vibrations that can be reduced by additional support.
