IMPORTANT OPERATING PRECAUTIONS!
The quality of washing often affects the validity of test results. To assure adequate washing:
• Perform periodic dispense volume repeatability checks as described in this manual.
• Rinse the wash head and probe after use.
• Handle and store the wash head carefully to prevent damage.
• Use the prime cycle before each wash.
• Watch the instrument to see that the probe and wash head dispense is functioning
properly.
Be sure to run a sufficient number of controls in each assay. If controls are not within their
acceptable limits, or if you suspect incomplete or non-uniform washing, disregard test results.
Do not operate the instrument if the pressure is unstable or if the probe or wash head probes
are damaged.
