Section 5 Continuous Flow Introduction, Installation, and Operation
Always verify the valve settings before running a program. If a con-
troller is reset or moved to a different power source, it will revert back
to default settings (Active).
1. Degas liquids if appropriate.
2. Purge air from the system:
a. Fill both pumps completely by pressing
each pump to fill.
b. Route the outlet to waste or reservoir and press
when fluid comes out of the outlet.
STOP
c. Open the valves to atmosphere by pressing
selecting each valve to open.
d. Zero the pressure in each pump by pressing
selecting each pump to zero.
e. Connect the outlet tubing and fill each pump once more.
3. Reset total volume (refer to Figure 5-5).
1. Open the valves to atmosphere by pressing
selecting each valve to open.
2. Zero the pressure in each pump by pressing
selecting each pump to zero.
3. Fill both pumps completely by pressing
each pump to fill.
4. Pressurize both pumps by pressing
rate and target pressure value will be displayed. Press 'D' to con-
tinue pressurization.
5. Reset total volume (refer to Figure 5-5).
Using a temperature control jacket for cooling is recommended
when pumping liquefied gases in continuous mode. These fluids
tend to create heat as a result of compression work, which can lead
to performance issues over time.
6. Equilibration - When the pumps begin running, the system will
go through an equilibration phase, during which both pumps
must be full and delivering fluid.
7. Additional guidelines - Become familiar with the following guide-
lines:
• Pressure limits for continuous Constant Flow Mode are set by
the limits of pump A for the A-B pair and pump C for the C-D
pair.
