Replacing the diaphragm:
➨ Position new diaphragm between diaphragm clamping disc
with square head screw and diaphragm support disc.
☞ Note: Position diaphragm with white PTFE side to diaphragm
clamping disc (to pump chamber).
☞ Make sure that the square head screw of the diaphragm
clamping disc is correctly seated in the guide hole of the
diaphragm support disc.
➨ Use a face wrench to remove diaphragm support disc.
➨ Check for washers. Do not mix the washers from the differ-
ent heads. Make sure that the original number is reassem-
bled at the individual pump head.
☞ Smaller number of washers: The pump will not attain ulti-
mate vacuum. More washers: Clamping disc will hit head
cover; noise or even blockade of the pump.
