14693e - 31 Mar 03 3 - 3 3 System Operation
3.1 Daily Start-up
WARNING:
Verification of the absence of all sanitizers, cleaners, disinfectants and
chlorine/chloramines must be performed before RO product water is used for any
patient related uses.
1. Connect the RO unit to the required utilities (feed water, drain, and power).
2. Ensure that all the valves in the water supply line to the RO are open.
3. Ensure that all pre-RO devices have been flushed and tested and are operating
within their specifications.
4. Ensure that the product rinse line is connected to the RO, with the other end in a
drain.
5. Move the inlet water valve switch to the open position. When water flows to
drain, the RO pump power switch can be moved to the on position.
6. The "Percent Rejection" monitor should indicate 95% rejection within 2 minutes
of start-up. It is normal for rejection to drop off until membranes have rinsed up
to optimum quality.
7. The TDS monitor should stabilize within 2 minutes of start-up. The TDS during
this time may be higher than the alarm set point. The audible alarm may be
muted at this time by pressing the alarm mute switch. The alarm mute switch will
silence the audible alarm for 30 - 45 seconds each time the switch is used.
WARNING:
When the RO is used for dialysis service, a test for disinfectant residual MUST be
performed.
8. Record data on a daily log sheet.
WARNING:
Any data that does not meet minimum standards set at your facility must be
reported to the medical director. The RO should not be placed in service until
readings are acceptable.
9. The Millenium™ RO is now ready for connection to the dialysis machine.
3.2 Shut Down Procedure
1. Turn off the RO pump power switch.
2. Turn off the inlet water valve switch.
3. Turn off the inlet water supply.
