Turn on the sample stream.3. Slowly open the flow regulator (Figure 11) counterclockwise until consistent flow isachieved at a rate in which the flow cell can be flushed out for about two minutes.Check for leaks at this time. If leaks occur, fix by ensuring all connections are snug butnot overtightened.4. Adjust the flow regulator on the flow cell until the water begins to drain out the leftdrain port. This results in a constant 14 L/hour (200–250 mL/min) flow rate.5. Supply power to the controller and it will automatically power on.6. Allow the instrument to stabilize before proceeding.
