E4H Series
Operation & Maintenance Manual
18
Once the desired flow rate is achieved [250 psi (17.3 bar) operating pressure]
no further valve adjustment is needed.
NOTE: Permeate flow rates are dependent upon temperature and conditions
at your site. Contact your dealer if you have any questions.
18. The system is now operational.
19. Before putting the machine into final operation, continue to run the permeate
and concentrate streams to drain for at least 30 minutes. This is done to
ensure that all of the bactericide has been removed from the membranes.
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 piping on the
permeate and concentrate outlet lines.
21. Make any necessary final adjustments to flows and pressure according to step
17.
NOTE: The membrane(s) in your machine are rated for certain flow rates at
77ºF (25ºC). Maximum flow rates are achieved when the membranes have
been completely rinsed and on-line for at least 24 hours.
22. A daily log sheet, which includes general operating conditions (pressures,
flows, concentrations, pH, and pretreatment conditions), and routine or special
maintenance (flushing or cleaning as needed) must be kept. This log sheet will
be required by GE Water & Process Technologies if a warranty question arises.
4. OPERATION AND MAINTENANCE
The operation and maintenance of your GE Water & Process Technologies E4H
Machine is relatively simple but requires regular data recording and routine
preventative maintenance. We cannot emphasize too strongly the importance of
filling out the daily log sheet during each operating shift. A data sheet was filled out
upon start-up containing pertinent facts on the operation of your machine. These two
records are invaluable in diagnosing the performance of the equipment 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 Water & Process Technologies Application
Engineering Department. The three preventative maintenance procedures, which
must be done on a regular basis are as follows:
1. Change the pre-filter cartridge.
2. Flush the machine daily.
3. Clean the machine with approved GE Water & Process Technologies cleaners.
