Assembling the Pump Head
5
Insert the support ring and pump head ferrules into the
piston housing. Observe the pins on the support ring,
which help you assembling the pump head correctly.
6 Assemble the pump head by putting the pump chamber
housing on top of the support ring. Insert and tighten the
two pump head screws.
Do NOT install the inlet and outlet valves (primary
pump head) and the high-pressure filter (secondary
pump head) at this stage.
