Plumbing All NGC Systems
Table 19 lists the tasks for plumbing all NGC systems. The tasks are explained in
detail in the sections that follow.
Plumbing the System Pumps Wash Lines
All configurations ship with the pump wash system preplumbed except for the inlet
and outlet tubing. Plumbing the inlet and outlet tubing is specific to the type of
pump (system pump configuration or sample pump). The following images display 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.
Table 19. Plumbing tasks for all NGC systems
Task
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 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
