Z Series RO System by GE Osmonics
9. Turn on the RO unit. When the RO system is equipped with a Disinfect Alarm
Monitor and RO Status Monitor disinfect operations may commence only when
both disinfect key switches are activated, the RO unit power switch is turned on,
and the alarm timer has expired. If the Disinfect Alarm Monitor is not included in
the RO system the Disinfect Start key switch can be turned ON to circulate the
solution through the RO system.
CAUTION:
Check that there is waste flow within 10 seconds. If not, turn off power and verify that
the Disinfect Inlet Valve is open and tank connections are secure.
10. Allow the disinfect solution to circulate through the system for 5 minutes. After 3
minutes of recirculation, test the product line effluent for the presence of
Renalin
®
. If necessary, continue recirculation until a positive test is obtained.
Follow specific facility procedures for loop piping point of use testing.
CAUTION:
Do not allow the solution temperature to climb above 25°C during this step. Failure to
control temperature will result in rapid deterioration of the membrane, resulting in poor
rejection.
11. Turn off the RO unit. RO systems equipped with a Disinfect Alarm Monitor will
use the RO unit power switch to turn off the pump and stop circulation. RO
systems without a Disinfect Alarm Monitor will use the Disinfect Start key switch
to turn off the pump.
12. Remove the RO waste and product lines from the disinfect tank and connect to
drain. Loop piping disinfection will require the loop output to be connected to
drain. Direct Feed RO units having the loop disinfected will require the loop
return ball valve, mounted vertically just prior to pump housing, to be closed
during disinfectant solution draining. Protect product line from contamination.
13. Turn on the RO unit. When the RO system is equipped with a Disinfect Alarm
Monitor and RO Status Monitor operation may commence only when both
disinfect key switches are activated, the RO unit power switch is turned on, and
the alarm timer has expired. If the Disinfect Alarm Monitor is not included in the
RO system the Disinfect Start key switch can be turned ON to drain the disinfect
solution.
14. Run disinfectant solution to drain until the disinfect tank is almost empty.
CAUTION:
Do not allow air to be drawn into the RO system
,
,
as this will damage the pump.
15. Turn off the RO unit and pour the last amounts of cleaner into drain to protect the
pump from running dry. RO systems equipped with a Disinfect Alarm Monitor
will use the RO unit power switch to turn off the pump and stop circulation. RO
systems without a Disinfect Alarm Monitor will use the Disinfect key switches to
turn off the pump.
