Prior to removing the regulator and related parts
from the manifold, flush the system with solvent
and purge with air.
Using tool A10676-00, remove the regulator cap.
Remove the six (6) stainless steel screws with a
flat head screwdriver. Carefully remove the
regulator bonnet. Then remove the diaphragm
assembly. Next, remove the needle and seat
assembly using a 3/16" Hex key.
Clean entire regulator with solvent and blow dry.
Do not use any metal object to remove dried paint
from any surface. Damage to the diaphragm
sealing surface and the needle seat assembly will
result in leaks and may permanently damage
valve manifold. If regulator was disassembled
because of leakage (fluid downstream of regula-
tor), discard entire needle, seat, o-ring, and spring
and replace with new.

Remove the screw holding the upper plate and
lower plate of the assembly with a Phillips
screwdriver. Pull parts apart and discard the
diaphragm. Inspect the lower plate for any damage,
replace if necessary. Replace the o-ring that was
between the lower plate and the diaphragm.

Carefully place the o-ring on the lower plate,
center a new diaphragm over the parts, and center
the upper plate over these parts. Install the screw
with a small amount of Loctite (7969-05) on the
threads. Tighten together to a torque of 8-10 lbs•in
(.90-1.13 Nm). Make sure that Teflon (white side
of the diaphragm) faces towards the lower plate.

Install the spring into the center-most cavity of the
manifold. Place the pointed end of the needle onto
the center of the spring. Install the o-ring into the
cavity of the seat. Lightly lubricate the o-ring with
A11545-00 Petroleum jelly. Secure the needle/
seat assembly by screwing the seat retainer into
the regulator cavity until a torque of 8-10 lbs•in
(.90-1.13 Nm) is obtained. Use a 3/16" Hex key
driver.

Install assembly with the black rubber face towards
the outside and align with the screw holes in the
cavity. Place the regulator bonnet over the
diaphragm assembly and align with screw holes of
the diaphragm assembly and cavity. Insert all six
(6) stainless steel scews and tighten in an
alternating 180
° method. Install regulator cap and
tighten to 125-135 lbs•in (14.1-15.3 Nm).
