6. Apply DC power after as little time as possible. If too much water (with ions) is
sent through the module(s) before power is supplied the excess ions will need to
be removed with a longer regeneration procedure.
7. Check to be sure all three (3) streams for all modules are flowing at the
recommended, design flows.
8. Check that the pressure drops of all three (3) streams are approximately correct.
9. Check all modules for startup current. The amperage may be higher than normal
on startup and should drop to a nominal level within 1 hour. All modules should
have similar currents to one another.
10. Check that the ion concentrations in the concentrate streams are all high. If the
module(s) are running at 90% recovery, then the concentrate should have about
10 times the concentration of the feed. Perform a mass balance on the inlet and
outlet ions to determine if the module(s) are regenerating (excess ions in outlet)
or underpowered (too few ions in outlet).
11. Check all system permissions and interrupts. Check all flow sensors to ensure
that minimum flows are set properly and the correct signals are presented to the
control system.
12. If not immediately, then after about one (1) hour, the product resistivity should
rise to the proper level. If excess ions were introduced during the startup
procedure, then a regeneration cycle may be required before quality is achieved.
13. Check torque in the un-pressurized state (with no pressure) and re-adjust.
Follow up with the recommended periodic torque procedure.
14. Leave a maintenance manual at the site with the customer.
