Action Step
•
Prime the Pump and the flow path. Tap Start flow to run the Pump.
•
Place the outlet tubing from the Wash valve (Waste port) in a pre-
weighed collection tube.
Note:
Before starting Diagnostics, prime the flow path with water and make sure
that the outlet tubing where the pumped water is collected, is filled with
demineralized water. This ensures that the volume of the collected water
corresponds to the pumped volume.
4
Collect at least 1 ml of water in the collection tube. Measure and note the
collection time. 5
•
Tap Stop flow to turn the Pump OFF.
•
Note the volume of the collected water (weigh the pre-weighed collection
tube containing the collected water and estimate the volume of the
pumped water).
•
Calculate the flow rate and verify that it corresponds to the set flow rate.
Note:
If the collected water does not correspond to the required volume (i.e., the
Pump does not deliver water with the intended flow rate), inspect the condition
of the pump tubing, then re-calibrate the Pump and re-diagnose.
6
If the collected water does not correspond to the required volume replace
the Pump tubing.
After replacing the pump tubing, calibrate and diagnose the Pump again. If
the collected water does not correspond to the required volume replace the
Pump.
If the Pump is replaced with a new one, tap Reset to reset Pump run to 0
hours. 7
