GE E4H-CE Series, E8-CE Series, 000 gpd to 288 manual The system is now operational

15.As the machine purges the air and fills with water, the pressure will gradually increase. Water should flow through the permeate and concentrate piping, viewed on the individual flow meters. If you do not see flow, turn the machine OFF and return to Section 3.2 (Initial Start-Up).

16.Gradually adjust the concentrate flow control valve. As you adjust the valve, watch the average pressure (Pavg) and the your concentrate flow meter. Adjust the valve until your concentrate flow meter displays the desired flow and does not exceed Pmax. If Pmax is exceeded before the valve is completely closed, open the recycle flow control valve one full turn, then continue to adjust the concentrate flow valve.

17.With the concentrate flow control valve set to obtain the desired concentrate flow and the pressure below Pmax, gradually adjust the recycle flow control valve until Pavg reaches 7.6 bar (110 psi). Readjust the concentrate and then the recycle valves, if necessary.

18.Once the desired flow rate is achieved [7.6 bar (110 psi)] operating pressure, no further valve adjustment is needed.

NOTE: Permeate flow rates are dependent upon temperature and conditions at your site. Contact your distributor if you have any questions.

The system is now operational.

19.Before putting the machine into final operation, continue to run the permeate and concentrate streams to the drain for at least thirty (30) minutes. This is done to ensure that all the preservative have been removed from the membrane elements.

20.Connect the permeate line to the point-of-use of the permeate. Check for leaks and ensure that you have no kinks in hoses or blockage of any plumbing on the permeate and concentrate outlet lines.

21.Make any final adjustments for flow and pressure, according to Step 18, if need- ed.

22.Complete and create copies of the Start-Up Log Sheet (Section 7.2). A Daily Log Sheet (Section 7.3), including general operating conditions (pressures, flow, con- centrations, pH, and pretreatment conditions) and routine or special maintenance (flushing or cleaning as needed) must be kept. GE Osmonics will require these Log Sheets if a warranty question arises.
