Assembling the Pump Head
1
Use the soft plastic side of the insert tool for inserting
the piston seal to the pump chamber housing. Wet the
piston seal with isopropanol or another suitable solvent
before insertion.
2 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.
