5.6.1 Defining Operation

Section 5 Continuous Flow Introduction, Installation, & Operation
Once your valve package has been properly installed and you
have ensured that fluid connections are leak-free, the system is
ready for operation.
Note
Teledyne Isco convention is to name the pumps "pump A" and
"pump B," reading from left to right.
Before running in continuous flow mode, become familiar with
independent mode, which allows the controller to operate two
pumps independently and simultaneously. You must operate the
two pumps manually for initial setup, i.e. refill and purging of
air. If the Teledyne Isco air valve package is used, the air valves
are switched through ACCESS CTRL. When air valves are used,
lights on the air valve actuator indicate which valves are open.
