5. If the preferred flow rate is already selected, but the pump flow is off,
click the switch to start the pump at the selected flow rate.

6. Enter the minimum and maximum pressure limits. Setting pressure limits
ensures that the DP/SP will automatically stop if a system malfunction
occurs.

a. Capillary IC pumps shipped before February 17, 2011 were rated for lower
operating pressures than the pumps currently being shipped. Refer to the im-
portant note on the next page for details.
b. If the installed version of EG degas (capillary) cartridge is not rated for
35 MPa (5000 psi), change the default high pressure limit to 21 MPa
(3000 psi). Refer to the important note on the next page for details.

After starting the pump or changing the flow rate, wait
at least 5 minutes (longer for flow rates below
1.0 mL/min) before beginning an analysis. This allows
the DP/SP to stabilize the flow rate.
