5.15 Priming the Pump with Isopropyl Alcohol
NOTE Prime the pump heads with isopropyl alcohol only if the
two standard priming procedures described in
Section B.13 are unsuccessful.
1. Connect a 10-mL syringe
(P/N 054578) filled with
isopropyl alcohol (IPA) to
the port in the primary
pump head (see
Figure 5-29 ).
2. Open the waste valve on
the secondary pump head
(see
Figure 5-29 ) by
turning the knob one-
quarter to one-half turn
counterclockwise.

3. Click
Pump On
on the Chromeleon Control panel to turn on the pump motor.
4. Open the priming valve on the primary pump head by turning it one-quarter to
one-half turn counterclockwise.
5. Use the syringe to slowly push alcohol through the pump.
NOTE Be careful not to push any air trapped in the syringe
through the pump. Check the waste line from the
secondary pump head to verify that there are no air
bubbles.
6. Close the priming valve. Do not overtighten. Disconnect the syringe from
the priming valve.
7. Let the pump run for several minutes, to purge alcohol from the pump heads,
and then click Prime and flush the heads with the desired eluent.
