are below the 20 or 32, increase the back pressure on the filter by closing the outlet valve
until the pressures are reached during a back pressure.
e. Verify that during a back wash of the screen filter, that water is discharged down the drain
and stops as the back wash stops.
f. Verify that the CHC pressure remains with tolerance. Adjust if necessary.
17. Select a Bleed Test function and make sure the blow down valve changes appropriately.
(Main screen, press Bleed F3, press Bleed Test F1 key)
18. Verify that during an open blow down valve, water is discharged to the drain and that as the
valve closes, and the flow to the drain stops.
19. Adjust the flow control valves to achieve 5-8 gpm flow through the flow meter and corrosion
coupon rack. If your unit does not have a flow meter, open the valve 1/3 or to the mark as set
by the manufacturing group (indicated with permanent marker)
20. Calibrate the conductivity meter probe and select the units that is familiar to the customer, the
user can select from µS/cm or ppm. Adjust the bleed set point to the desired level against the
makeup water conductivity as specified within the quote.
21. Close down the Forsta filter discharge valve and the Separator discharge valve, so that the
pressure on the separator increases to above 50 psi, but not above the range as shown on the
discharge gauge of the filter.
22. Calibrate the pressure transducers at this time as shown in the manual for HI Cal pressures.
23. Turn OFF the skid’s pump and verify the transducer pressure values, drop back to Zero, turn
the pump power back ON and verify the reading return to a value representative of the gauge
pressure.
24. Open the Auto Screen filter’s discharge valve (valve that goes back to pump suction from the
screen filter discharge connection) so that the outlet pressure of the separator decreases by 5
PSI.
25. Open the filter discharge valve so that the normal operating pressure is reached on the
separator.
26. Initiate a Filter Back Wash and verify that the filter inlet pressure stays within its operation
range (see step 11.e) make adjustments as needed.
27. Record the normal operation pressure of the screen filter’s outlet. This value minus 8 psi must
be entered into the Trip Pressure set point within the CHCCS setting screens.
28. Mark with a permanent marker all valves, and flow meters so that the current settings are
noted as well as any ranges that are appropriate.
29. Turn OFF the pump, Turn OFF the Main Power Disconnect Switch. Verify that power has
been removed from all systems, inspect the motor connectors, as well as electrical control
panel components for arcing or heating. If no indications are noted continue with operation. If
any indications of electrical issues are noted, contact the appropriate electrician to correct any
issues. Turn the power back on and record the Pump amperages from each leg of power.
30. Mark all Gauges with a permanent marker to show the initial pressure settings.
31. Verify that the Blow down duty cycle setting or blow down flow regulation valve settings are
appropriate. (you should never blow down more water than their makeup system is capable of
replacing at any one time). A good starting point is a Duty Cycle of 50%.
32. Review the hidden screen and verify the settings of the VCS. If changes are need, make those
changes and then return to this screen and take a picture of the screen information.
33. All data should be entered into Ulysses at this point and call made to EcoWater CHC
engineering to notify them of the Start Up CSR being created for their approval and
processing.
34. Return back into the CHCSC system settings and initiate a Save to User Defaults the current
configuration.
