To open the priming valve, turn the knob one-quarter to one-half turn
counterclockwise. When the priming valve is open, liquid can flow into
and out of the primary pump head via the port in the front of the valve.
NOTE The priming valve must be open when the pump is
being primed with a syringe or with isopropyl
alcohol. For detailed priming instructions, see
Section B.13 .
Secondary Pump Head
The secondary pump head delivers eluent to the remainder of the
chromatography system (the injection valve, column, and detector). The
waste valve is located on the front of the secondary pump head (see
Figure 2-18 ).
To open the waste valve, turn the knob one-quarter to one-half turn
counterclockwise. When the waste valve is in the open position, all output
is directed to waste.
NOTE The waste valve must be open when the pump is
being primed using the Prime button. For detailed
priming instructions, see Section B.13 .
