Caution: Be sure that the entered values for Flow, HPL
(high-pressure limit), and LPL (low-pressure limit) are
appropriate for your column. Some columns require a flow ramp
up. See the Care and Use Manual for your column.
Caution: If your 515 pump is connected to a Waters 680 Automated
Gradient Controller, do not power off the controller if the pump is
running. Doing so may damage the column due to a spurious pressure
output signal from the controller when it is powered off. To avoid this
situation, power off the pump before you power off the controller.
