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 cleaning 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. Adjust the pump pressure to 100 psi or less and circulate the cleaning solution for
15 minutes. This will allow more flow of cleaner on the reject side of the RO
membrane to flush particulates away.
CAUTION:
The BIOSAN
 will foam; this is normal. Keeping the ‘return’ hose under the liquid level
in the tank may minimize the foam. Damage to the pump may occur if foam is drawn
into the pump.
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. Allow the BIOSAN™ to dwell for one hour.
13. Rinse the RO system. Reference section 4.3.1.2, Post-Cleaning Rinse Procedure.
