Connecting For High-Pressure Gradient Operation - Waters 515 HPLC Operator's Manual

Connecting the outlet tube
Tip:
Leave the instrument end of the outlet tubing disconnected until
you have primed the pump and flushed the system as described in
"Preparing the 515 pump" on page
2. After you prime the pump and purge the system, press the free end of
the tubing assembly into the injector or next device in your HPLC
system and finger-tighten the compression screw. Then use the
5/16-inch wrench to tighten the screw another 1/8 turn.

Connecting for high-pressure gradient operation

The figure below shows recommended plumbing configurations when you use
two or three remotely controlled 515 pumps for high pressure gradients. If
your application requires high-pressure gradient delivery with minimal delay
volumes, plumb the pumps as shown in the figure below (without using the
optional mixer). If your application requires high-pressure gradient delivery
with minimal compositional ripple, install the optional mixer, part number
WAT051518.
