Open the sample inlet valve, see A .• Position the valve with pointed end facing up for open position.2. Open the bypass/needle valve by turning it counterclockwise, see B .• Check for appropriate sample flow.• Adjust pressure regulator if required. See step 3.3. Adjust the knob on the pressure regulator, see C , so the ball in theflow meter indicates the correct flow rate reading, see D . The flowrate should be adjusted to 40 mL/minute.• Pull out the knob to unlock the setting and adjust the flow rate.• Turn the knob clockwise to increase the flow rate.• Turn the knob counterclockwise to decrease the flow rate.• Push in the knob to lock the setting.4. Push in the diverter valve on the flow cell.• Flow cell will begin to fill.5. Flush the flow cell for 10 to 60 minutes. The sample will drain fromthe siphon tube into the siphon drain to the waste.6.
