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 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!
