6. Prepare the cleaning solution by adding the amount of cleaner as specified on
the labeling to two gallons of pretreated or RO product water.
CAUTION:
Water to be used must be chlorine free or damage to the RO membranes may
result.
7. Turn the RO power switch off and close the product valve.
WARNING:
Label machine with appropriate warning signs such as "Do Not Use / Contains
BIOSAN" to prevent use of the RO until it is properly rinsed.
8. Connect the product line to the white fitting on the disinfect/cleaning tank.
Open the product valve.
9. Connect the feed line (green QD) from the pre-filter outlet to the green fitting on
the disinfect tank.
10. Connect the drain line (red QD) extension and connect the female portion to the
red fitting on the disinfect tank.
CAUTION:
By connecting all the lines to the disinfect/cleaning tank, the system is set-up for
recirculation. Never leave the unit unattended in the recirculation mode.
4.3.2.2 BIOSAN Recirculation and Dwell Time
1. Rotate the Dialyze/Flush valve to the Dialyze position. This will allow the
BIOSAN to pass from the rejection side of the membrane through to the product
side of the membrane for total system exposure to the cleaning solution once the
RO is turned on in disinfect mode (step #2).
2. Turn the F-801 RO unit ON. Let the RO operate for three minutes.
CAUTION:
Check that there is waste flow within 10 seconds. If not, turn RO OFF and verify
that the disinfect line is connected properly.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY. Damage will occur if pump is run
dry.
CAUTION:
Do not allow air or foam to be drawn up into the RO unit, as this will damage the
pump.
NOTE:
BIOSAN will foam; this is normal. If using a closed container, provide a vent to
the atmosphere to relieve pressure.
