7.4 Replacing diaphragms and valves of MVP 040-2
NOTICE
Property damage from incorrect installation
Change in dead volume due to incorrect installation of the original spacer disks impairs the final vac-
uum or leads to bearing damage.
► During disassembly, keep the existing spacer disks separate per installation location.
► Reinstall the same number of original spacer disks per diaphragm head.
Avoid interchanging components
Always dismantle and mount only the pump head on one pump side in order to avoid inter-
changing the components.
The procedures are identical for both pump heads.
