Liquefied Gases Checklist:
1. Open the valves to atmosphere by pressing
selecting each valve to open.
2. Zero the pressure in each pump by pressing
and selecting each pump to zero.
3. Fill both pumps completely by pressing
ing each pump to fill.
4. Pressurize both pumps by pressing
flow rate and target pressure value will be displayed. Press
D to continue pressurization.
5. Reset total volume (see Figure B-4).
Equilibration – When the pumps begin running, the system
will go through an equilibration phase, during which both pumps
must be full and delivering fluid.
Additional guidelines – Please become familiar with the fol-
lowing guidelines:
• 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.
• Temperature changes can cause pressure fluctuations.
For available temperature control options, contact
Teledyne Isco.
• For correct overpressure response, shutdown must be
set to
• Enter the same refill rate separately for pumps A, B, C,
and D.
The refill rate should always be as high as possible to
allow time for refill and repressurization before the next
switchover.
