SuperFlow® 350 Regulator
Reassembly of the SuperFlow® 350 Demand Regulator
bent tube mount nut. Rotating clockwise, thread
the large nut on the bent tube assembly onto the
inlet nipple 1 to 2 threads.
Ensure that the Teflon
®
ring is in place and en-
gage the bent tube nut to the side block fully un-
til it is hand tight. You may need to gently rock
the regulator body and/or the bent tube to fully
engage the side block nut.
Next, fully engage (clockwise) the large nut on
the bent tube into the regulator inlet until hand
tight. This will ensure the nut is bottomed on the
shoulder of the bent tube. Do not tighten further.
Loosen the jam nut on the regulator inlet
(counterclockwise), and engage the jam nut
fully to the large nut on the bent tube. Us-
ing a torque wrench and an
7/8”
open end
wrench hold the large nut on the regulator
end of the bent tube and tighten the jam nut
see "Torque Specs" on page APNDX-19 for correct
26) Ensuring the O-ring is in place, use a
torque wrench with a 1
3/8
" socket and an
extension to tighten the regulator mount
nut to see "Torque Specs" on page APNDX-19
for correct torque. Next, using a torque
wrench with an
11/16
adapter, torque the bent tube
nut to the side block see "Torque Specs" on page
27) Attach the whisker to each side of the face
port retainer using the screws, zinc anodes or
kidney plates and spacers, use Loctite
®
222.
Using a torque wrench with a flat blade screw-
driver adapter, carefully torque these screws
see "Torque Specs" on page APNDX-19 for correct
The Quad Valve must be properly connected to the
regulator and the quad exhaust extension on the pod.
28) Adjust the regulator following instructions in
29) Make sure the diaphragm & mating surfaces
are clean and free of lubricant.
30) Install the diaphragm, cover and screw. Af-
ter all adjustments and fine tuning are complete,
tighten the screw see "Torque Specs" on page
APNDX-19 for correct torque using a torque screw-
driver.

350
Regulator
1) If not already done, remove the clamp, cover
and diaphragm.
2) Screw the adjustment knob (clockwise) all the
way in, towards the regulator body.
3) Pressurize the regulator to between 120-150
p.s.i.g. of supply pressure.
4) Screw the adjustment knob out (counterclock-
wise) until the regulator starts to free flow, then
screw the adjustment knob in (clockwise) until
the free-flow just stops. Depress the lever several
times to ensure the free-flow has stopped.
If the free flow does not stop, the lock nut is too
tight. If the roller lever is sloppy (loose) the lock
nut is too loose.
5) Insert the inlet valve holding tool into the bal-
