6. Start the pump at the zero stroke length setting and slowly increase the setting to 100 to prime the
pump. If this does not work, it will be necessary to fill the suction line.
7. Filling of the suction line will necessitate the use of a foot valve or similar device at the end of the
suction line so that liquid can be maintained above the reservoir level. Remove the suction valve
assembly, fill the line, replace the suction valve, then remove the discharge valve assembly and fill
the reagent head as described in Step (3) above. The pump will now self-prime when started up per
step (4) above. Use appropriate precautions if handling process fluid. Ensure that any other fluid
used for priming is compatible with the product that will be pumped.
