F-801 Internal RO System by GE Osmonics
12552e – 27 Feb 04 3 - 4 4 System Operation
WARNING:
Only the cold water supply should be used. If blending of hot and cold water is to
occur, an appropriate temperature blend valve must be used, and the temperature
of the incoming water supply must be continuously monitored, and not be allowed
to rise above 30°C (86°F). Excessively high water temperature may cause severe
patient injury or death.
6. Turn the F-801 RO unit ON. The on/off switch is located on the back of the
remote monitoring module atop the dialysis machine.
CAUTION:
Some pump noise (chattering) is normal in the flush position. Excessive pump
noise (chattering) can be damaging to the pump. The RO is in “flush” from the
full open (flush) position to just before the fully closed (operate) position. Adjust
it by partly closing the flush valve to reduce chattering of the pump.
7. 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.
8. 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.
9. Perform the following routine checks before each use and record on the
Operation 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.
Read the pump pressure gauge, it should read between 140 – 160 PSI.
Read the inlet pre-filter pressure gauge, it should read between 30 – 100 PSI.
Read the outlet pre-filter pressure gauge, it should read between 30 – 100 PSI
with no more than 8 PSI difference between initial clean pre and post filter
readings. Compare log sheet recordings for changes.
Read the product pressure gauge, it should read between 35 – 40 PSI. The
product pressure should be read with the product water hose connected to the
Fresenius inlet, or with the product outlet valve closed.
