2-8 Installing the Waters 515 Pump
5. Firmly seat the tubing end into the inlet manifold on the pump, then
finger-tighten the compression screw.
Connecting eluent tubing to the eluent reservoir
To connect the eluent tubing to the eluent reservoir:
1. Insert the free end of the 1/8-inch PTFE inlet tubing into the cap of the
eluent reservoir.
2. Cut the 3-inch section of 0.149-inch OD PTFE tubing at its midpoint and
slide one of the resulting 1.5-inch sections over the end of the 1/8-inch
PTFE tubing for about 3/4 of an inch (1.9 cm).
3. Insert the stainless tubing fitting on the solvent filter into the open end
of the 0.149-inch OD tubing.
4. Install the cap onto the eluent reservoir and push the tubing through
the cap until the filter reaches the bottom of the reservoir.
Connecting the pump outlet
Follow the instructions in this section to connect the pump outlet to the next
instrument in the flow path. If you are configuring multiple pumps for
high-pressure gradient delivery, also see “Connecting for high-pressure
gradient operation” on page 2-11.
Caution: To avoid damaging the ferrule, do not overtighten the
compression screw.
Caution: To avoid having eluent leak from the pump outlet, position
the eluent reservoir below the pump inlet manifold until the pump
outlet is connected to the system.
