268 EASY-nLC 1200 Troubleshooting & Maintenance Guide
The pump and valve compartment behind the right panel of the EASY-nLC instrument
contains all the flow lines between the components. In addition to pumps and valves, the
solvent delivery and waste system includes several filters and four check valves. The two check
valves on each solvent line ensure that solvent is drawn from the solvent bottles and ejected to
waste without switching valve positions.
Table 32 lists the tubing requirements and identifies the tubing components shown in
Figure 187. The Low-Pressure Solvent Line Kit (P/N LC593) contains the Tees, check valves,
and low-pressure solvent lines to connect one pump (A or B) to the waste system and to its
corresponding solvent bottle and six-port rotary valve.
