B.13.2 Priming the Pump Heads with the Prime Button
NOTE Perform this procedure after priming the eluent
lines (see Section B.13.1 ).
1. Check that the priming valve on the primary pump head is closed (see
Figure B-29 ).
2. Open the waste valve on the secondary pump head by turning the
knob one-quarter to one-half turn counterclockwise (see
Figure B-29 ). Opening the valve directs the eluent flow path to waste
and eliminates backpressure.
3. Touch Prime on the ICS-2000 touch screen
HOME
page. Confirm that
the waste valve is open by pressing
OK
when the reminder message
appears. The pump will begin pumping at approximately 3 mL/min.
4. Continue priming the ICS-2000 until no air bubbles are exiting the
pump waste line.
5. Press
Pump Off
.
6. Close the waste valve. Do not overtighten. The pump is now ready
for operation.
7. Go on to Section B.14 .
NOTE If the two standard priming procedures described
above are unsuccessful, prime the pump with
isopropyl alcohol. See
Section 5.15 for instructions.
