STEP 6:
Clean or replace plastic slip ring.
Clean the brass diaphragm retainer.
Lightly lubricate retainer threads
with a food grade petroleum jelly or
equal. Place slip ring into retainer.
Screw retainer with slip ring onto
main guide, securing inner dia-
phragm. Make sure the retainer is
secure.
STEP 7:
Push inner diaphragm back through
main guide until top of the dia-
phragm is flush with the top of the
retainer.
STEP 8:
Turn guide/diaphragm assem-
bly upside down and work disc
holder into guide until flush with
diaphragm.
STEP 9:
Push the disc holder through the
guide while holding the diaphragm
flush against the end of the holder.
Continue until the holder stops on
the guide. Place the assembly on
a flat surface with the diaphragm
facing up.
This will ensure that excess rubber
will roll to the inside of the main
guide when the holder assembly
strokes, otherwise the diaphragm
will crack and leak.
STEP 10:
Place flow washer on top of the
diaphragm with cross channels fac-
ing upward (Series 860 and 880V
ONLY). Line up the center holes,
then place the spring into the guide.

STEP 11:
Place the spring button over the
spring. While pressing the button
firmly against the inner diaphragm,
insert the pan head retaining screw.
860 and 880V require a drilled flow
screw.
Flow screw must have two drilled
holes intersecting each other and
unobstructed. Place the previously
removed decal or tape over the
screw head to protect the outer
diaphragm.
STEP 12:
Reassemble disc and lower the
guide to the disc holder. DO NOT
ALLOW THE DISC HOLDER TO
TURN OR TWIST DURING THIS
OPERATION. Clean, lubricate and
install main guide O-ring.
Models 825YD and 826 YD use a
Stainless Steel Lower Guide and a
Disc Washer in place of the Plastic
Lower Guide as shown.
STEP 13:
Place new outer diaphragm upside
down on a flat service and insert the
module as shown.
STEP 14:
Push the flange section of the
diaphragm down around the base
of the module until it is partially
inverted as shown.

STEP 15:
Clean inside surfaces of the relief
valve and push in the module
assembly, being careful not to pinch
the guide's O-ring.
Note: The lower guide must align
itself properly with the seat ring
once all of the parts are assembled
in the body for the relief valve to
function properly.
STEP 16:
Take the partially inverted dia-
phragm and place it over the spring
button of the module. Take a blunt
tool and carefully work the dia-
phragm in and around the button.
Line up diaphragm bolt holes with
body flange bolt holes.
STEP 17:
Replace the cover and check for
proper positioning.
