Once the desired flow rate is achieved [250 psi (17.2 bar) operating pres-
sure] no further valve adjustment is needed.
The table below shows flow rates at 50%, 66% and 75% recovery for the
E4H models. Use this table in adjusting flow rates.
NOTE
: Permeate flow rates are dependent upon temperature and con-
ditions at your site. Contact your dealer if you have any ques-
tions.

Machine Recovery
19. The system is now operational.
20. Before putting the machine into final operation, continue to run the per-
meate 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 mem-
brane elements.
21. 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 pip-
ing on the permeate and concentrate outlet lines.
22. Make any necessary final adjustments to flows and pressure according to
Step 18.
NOTE
: The membrane elements in your machine are rated for certain
flow rates at 77ºF (25ºC). Maximum flow rates are achieved
when the membrane elements have been completely rinsed and
on-line for at least 24 hours.
