Assembling the pump head
All position numbers of the items described refer to Fig. 30 and Fig. 31.
1. Always exchange the piston seals (item {3.11} and {3.11a}) after
disassembly of the pump head. Exchange the O-rings (item {3.21})
only if necessary.
2. If you have removed the seal holders from the housing, replace
them very carefully with the plane sides facing each other.
Otherwise the seal holders cannot be replaced without damaging
them.
