ADJUST THE PRESSURE RELEASE VALVE
5). The Packing must follow the order as shown.
Apply grease all over the packing.
6). Place the Blue Diaphragm Needle (Packing installed)
into the Block and rotate the Blue Diaphragm clockwise
until you can feel the packing (Seals) make contact with
the valve cone.
Note: Do not tighten past this point, damage to stem
and packing can occur. Tightening past this point will
begin to compress the packing and will also make the
stem stick again.
7). Use a 1 inch wrench to grab the Adjustment Nut and
with a 1-⅛" wrench to tighten the Lock Nut. (Just snug tight).
8). Reinstall in machine to check operation.
• Best to plug o manifold and test to a pressure.
• If water comes out of weeping hole than go back to
step 6 and snug stem slightly more.
Note: The objective is to tighten the Adjustment Nut so
that the packing seals around the needle and still allows
the Blue Diaphragm to move the needle back and forth
to build pressure and drain.
