The pump should not operate at this point. 12. Check the rotation of the high-pressure pump: 12a Press the RO button so it is in the ON position. After the minimum inlet pressure [0.8 bar (11.6 psi)] is established and maintained for six (6) seconds, the high-pressure pump will start. 12b When the high-pressure pump starts, immediately press the RO button so it is in the OFF position. The motor should rotate clockwise while looking at the motor end of the high- pressure pump. If the motor is not rotating clockwise, change any two of the three leads in the motor starter and recheck rotation. WARNING: ALWAYS TURN POWER OFF TO CHANGE ANY WIRING. CAUTION: Operation of the pump backward, even for a short time, can cause damage to the pump. 13. Press the RO button so it is in the ON position. The high-pressure pump will operate and the machine will begin to build pressure. 14. As the machine is operating, watch the primary and final pressure gauges on the instrument panel. The machine is designed to operate at approximately 7.6 bar (110 psi). NOTE: Do not allow the pressure to exceed the maximum boost pressure (Pmax) specified for your machine model (Table 1.2). If the pressure exceeds Pmax, open the concentrate and/or recycle control valves until the pressure gauge shows Pmax or less. 14 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 needed. 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, concentrations, 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. 15 3.3 Daily Start-Up Check the machine to insure isolation valves are in the proper positions for operation. To turn the RO ON, press the RO button so it is in the ON position. If the alarm light is lit, push the “Alarm Reset” switch on the control enclosure and the alarm button on the OIT. If the alarm light stays lit, check the RO for an alarm condition. Otherwise, the main inlet valve will open, and the high-pressure pump will turn on. The high-pressure pump will not start if there is insufficient inlet pressure [< 0.8 bar (< 12 psi)]. 16 4.0 MACHINE OPERATION AND MAINTENANCE The operation and maintenance of a E-CE RO Series machine is relatively simple, but requires regular data recording and routine preventative maintenance. It cannot be emphasized enough the importance of filling out the Daily Log Sheet (Section 7.3) during each operating shift. A Start- Up Data Sheet was completed at start-up (Section 7.2) containing pertinent facts on the operation of your machine. These two records are invaluable in diagnosing the performance of the equipment or warranty issues, and must be kept for reference. If you have questions concerning the operation of your machine or the method of data recording, contact the GE Osmonics Application Engineering Department. Three preventative maintenance procedures, which must be done on a regular basis, are as follows: 1. Change the pre-filter cartridges. 2. Flush the machine. 3. Clean the machine with approved Osmonics cleaners. 4.1 Daily Log Sheets A Daily Log Sheet, wh...
