Plumbing All NGC Systems
Table 8 lists the tasks for plumbing all NGC systems. The tasks are explained in
detail in the sections that follow.
1. Inlet tubing to the pump head wash port on system pump A
2. Pump head wash priming line to the pump head wash port on
system pump B
3. 1/4-28 union to the priming line on system pump B
4. Pump head wash inlet to the 1/4-28 union attached to the pump head
wash priming line on system pump B
5. On the sample inject valve:
 Sample loop
 Injection port
 Waste lines (2)
6. Tube #2 from the outlet on the conductivity flow cell to the inlet on the
40 psi backpressure regulator
Plumbing the System Pumps Wash Lines
All configurations ship with the pump wash system preplumbed except for the inlet
and outlet tubing for the pump head wash. Plumbing the inlet and outlet tubing is
specific to the type of pump (system pump configuration or sample pump). The
following images show a detailed view of the connectivity and flow direction of the
rinse solution through the tubing segments for the system pumps and the sample
pump.
