Step 3: Release Pressure with Relief Valve
Release any pressure that may have been built up in the pump
head, by rotating the relief valve clockwise by ninety degrees
or 1/4 turn.
Step 4: Remove Intake and Discharge Lines
Remove the intake hose from the chemical pickup (suction)
side of the pump, but unscrew the discharge line from the
injection fitting on the water line.
Step 5: Remove Diaphragm Assembly
a) Remove the four screws that hold the pump head to the
pump body. You must loosen the screws a little at a time
in an "X" pattern, like upper left, lower right, lower left then
upper right.
b) Once the screws are removed, take off the pump head,
and then the outer O-ring.
c) Now you can remove the diaphragm assembly components.
•
the diaphragm
•
the auxiliary ring
•
the protective diaphragm
Rotate the diaphragm counter-clockwise to remove.
d) Carefully pull off the auxiliary ring, and set aside for
reassembly
e) Finally, you can remove the protective diaphragm. Take care
of the diaphragm, as it will be reused during assembly.
(The auxiliary ring and protective diaphragm are
both shown in the image to the right.)
Clean and inspect both parts before trying to rebuild the
pump, as these components are reused for assembly.
Take care of these items, as
they are reused for assembly!
