In-situ Quartz Flow Cell Cleaning Method
1. Shut off the water supply to the monitor if not already
done.
2.
Disconnect the ¼” supply tubing at inlet connection on
the monitor.
3. Fill the supplied wash bottle with cleaning fluid and
connect the ¼” bottle tubing to the inlet connection on
the monitor.
4. Hold a finger over the small vent hole in the wash bottle
cap, as shown in Figure 14.5.
5. Squeeze the bottle to get the cleaning fluid to flow through the
monitor.
6. Once the fluid starts to flow, remove finger from the vent
hole and place bottle on top of the monitor, as shown in
Figure 14.6. The fluid should continue to flow through the
monitor. If it stops go back to step 4.
7. Let all the fluid run through the quartz flow cell until the
bottle is empty, then disconnect the hose and bottle from
the fitting.
8. Let the fluid remain in the quartz flow cell for 5-10 minutes
until the quartz flow cell is clean.
9. Connect the supply line to the unit and open the valve to
start the flow running.
10. If UV values do not come back in line with the known UV
value, it is recommended to re-zero the monitor.
