Reassembling the pump set
7.5.1 General notes/Safety regulations
CAUTION
Improper reassembly
Damage to the pump!
▷
Reassemble the pump (set) in accordance with the general rules of sound
engineering practice.
▷
Use original spare parts only.
Always reassemble the pump in accordance with the corresponding general assembly
drawing or exploded view.
Check O-rings for any damage and replace by new O-rings, if required.
Always use new gaskets, making sure that they have the same thickness as the old
ones.
Always fit gaskets of asbestos-free materials or graphite without using lubricants
(e.g. copper grease, graphite paste).
Avoid the use of assembly adhesives, if possible.
Should an assembly adhesive be required after all, use a commercially available
contact adhesive (e.g. "Pattex") or sealant (e.g. HYLOMAR or Epple 33).
Only apply adhesive at selected points and in thin layers.
