Connect a 25 to 30 ml syringe to the purge valve of the left pump head of
System Pump B. Make sure that the syringe fits tightly into the purge con-
nector.
Open the purge valve by turning it counter-clockwise about three quarters
of a turn. Draw 5 to 10 ml of liquid slowly into the syringe with a rate of about
1 ml/s.
Close the purge valve by turning it clockwise. Disconnect the syringe and
discard its contents.
Connect the syringe to the purge valve on the right pump head of System
Pump B, and repeat steps 6 to 8. Keep the system flow running.
Check that there is no air left in the pump by following the instructions in
Validate prime or purge of System Pump A or B or Sample Pump, on page 172.
