F-801 Internal RO System by GE Osmonics

3.Turn the Dialyze/Flush valve to the Flush position and operate RO for an additional 5-10 minutes. The Flush mode will allow the flow of cleaner only to the reject side of the RO membrane to flush particles away. Very little or no product water will be made. Pump pressure during this step should read approximately 40-80 PSI.

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 by partly closing the flush valve to reduce the chattering of the pump.

NOTE:

The % rejection will fall below 85% and the TDS will rise considerably when the cleaner is re-circulated through the F-801 RO unit.

4.Turn the F-801 RO unit OFF.

WARNING:

The F-801 RO machine in now completely filled with BIOSAN cleaning solution and must NOT be used to supply water to the Fresenius dialysis machine or for any other purpose until a complete rinse procedure has been performed. See Cleaner Rinse Procedure below.

5.Allow the BIOSAN to dwell in the RO for a minimum of one hour.

NOTE:

Thin-film RO membranes: The F-801 RO unit may be stored in BIOSAN for up to two weeks.

4.3.2.3 BIOSAN Post-Cleaning Rinse Procedure

1.After the dwell time, remove the waste hose and clear accessory flush line from the cleaning solution and place it in the drain with the appropriate air gap.

2.Turn the RO on and run cleaning solution to the drain until the container is empty. This aids in emptying the container of cleaning solution.

CAUTION:

DO NOT ALLOW THE PUMP TO RUN DRY. As an alternative, the solution may be poured in the drain.

CAUTION:

Do not allow air or foam to be drawn into the RO system, as this will damage the pump.

3.When the disinfect/cleaning tank is empty, turn the F-801 RO unit OFF.

4.Reconnect the feed line to the pre-filter outlet (green QD).
