NOTE!
When tightening diaphragm cover it must
be ensured that diaphragm is
in neutral or out
.
If the diaphragm is in negative, the edge of the
diaphragm is not seated correctly in the dia-
phragm cover. This will damage the diaphragm so
it cannot seal correctly after having been dis-
mantled and re-assembled.
You must rotate the pump until the diaphragm is
neutral or out.

Reassemble with torque settings shown in
