SuperFlow® 350 Regulator
Reassembly of the SuperFlow® 350 Demand Regulator
on page SF350-19. If the button has only slight or no
free travel, the lever must be bent down.
B
WARNING
The lock nut must not be loosened
more than
⅛
turn to lower the height
of the lever. If more adjustment is nec-
essary the lever should be bent down-
ward. If the lock nut is loosened more
than
⅛
turn the lever will not have
enough travel for proper flow rates.
10) If the purge button travel is correct, the ad-
justment is complete.

350 Regulator Exhaust
Valve Replacement
Before removing the regulator exhaust valve,
carefully inspect the area around the edges to en-
sure the rubber exhaust valve is in contact with
the regulator body. The metal cross area of the
body under the valve may be slightly bent out-
ward resulting in the valve not sealing.
If the exhaust valve is high and not sealing, light-
ly press in on the metal cross, bending the metal
in slightly until the rubber valve seats. Remove
the existing regulator exhaust valve by pulling
it out of its mount hole. If the valve tears, make
sure that it is removed without any valve mate-
rial left inside the regulator.
NOTE
: Before installing the new exhaust valve,
ensure the spokes holding the valve are smooth,
even and not bent. The exhaust valve seating area
should be free of dirt and corrosion to ensure the
valve can lay flat and seal properly.
NEVER lu-
bricate the valve.
1) Remove the regulator clamp screw and clamp.
2) Remove the regulator cover and the dia-
phragm.
3) Install the new regulator exhaust valve by
placing the stem of the valve in through the hole
in the hub of the spokes from the outside of the
regulator. Gently, (using needle nose pliers) from
the inside of the regulator, pull the stem of the
valve through the hole in the hub of the spokes
until it pops into its seating area.
B
WARNING
The exhaust valve must be correctly
installed into the valve seat or it will
not seal correctly. This could lead to
a backflow of water into the helmet,
which could expose the diver to con-
taminants in the water. Depending
upon the properties of the contami-
nants, this could lead to serious per-
sonal injury or death.
B
WARNING
The exhaust valve must be installed in
the correct orientation into the regu-
lator body. If the valve is installed
backwards, the diver will be unable to
exhale. This could lead to suffocation
and death.
4) Reinstall the diaphragm, regulator cover,
clamp and clamp screw.
