Replacing the diaphragm
1. Lift diaphragm carefully.
2. Apply pressure to the clamping disc beside the diaphragm to bring connecting rod
into upper turning point position if necessary.
3. Use diaphragm key to grip under the diaphragm to the diaphragm support disc.
4. Apply pressure to the diaphragm clamping disc to bring the diaphragm into lower
turning point position. Press diaphragm key against diaphragm clamping disc and
unscrew diaphragm support disc with diaphragm.

assembly in a suitable solvent in order to aid separation of the two parts.
