If it is necessary to remove the regulator:
4. Pop Oral Nasal Mask free from Fitting.
5. Remove the six Screws holding the Retainer Plate.
The Regulator may now be pulled away from Helmet.
The internal parts of the exhaust are removed and ser-
viced, same as Side Exhaust. See section 3-G.
6. The Exhaust Deflector easily pops off and on.
7. When installing Regulator on the Helmet be sure to
clean old silicone sealant from O-ring area.
8. Install new O-ring. Apply approximately 1/8" of sili-
cone sealant all around O-ring area.
9. Insert the Regulator into Helmet. Be sure Oral Nasal
Fitting and O-ring are installed on the Plate prior to as-
sembly.
10. Install Retaining Plate with six Screws. Excess seal-
ant can be picked off with a toothpick after curing 20
minutes.
11. Pop the Oral Nasal into the Mount Fitting groove
with a blunt screwdriver.
12. Install Air Supply Tube. Snug the nuts with wrench,
but do not over tighten.
MILLER-10 REGULATOR
DESCRIPTION:
Gas enters the Inlet Seat and is held back by the Disc
and Retainer. When the diver inhales, the diaphragm
draws against the Demand Lever. This action pulls the
Disc and Retainer away from the InIet Seat, allowing
the gas to flow to the interior of the Regulator Body. Gas
passes through the Mask to the diver. The Double Spring
System work together in tandem to close the valve after
each inhalation, preventing free flow of gas into the Hel-
met. The Adjustment Knob changes the spring tension
which holds back the incoming gas supply until the diver
inhales and allows the diver to adjust the resistance to
free flow, according to the depth of the dive.
3-J DEMAND REGULATOR
GENERAL DESCRIPTION:
Miller has improved the standard Demand Regulator by
encasing the internal working parts in a heavy duty, cast
bronze housing and adding a closeable exhaust as a spe-
cial safety feature. The closeable exhaust may be used
to control buoyancy when using a dry suit without a valve
system. The heavy duty housing protects the Demand
Regulator parts from impact damage, thus saving the
diver many extra hours of maintenance and replacement
costs. Most important, the rugged housing helps protect
from a possible mishap due to a blow to the regulator.
The diver has the option of using free flow gas or de-
mand regulated gas, according to his needs. Demand
breathing is better for communication purposes due to
the reduction of gas noise. The Demand Regulator re-
ceives gas from the tube connected to the Free Flow
Manifold.
GENERAL MAINTENANCE & REPLACEMENT:
1. Remove Regulator Cover by unscrewing six Screws.
2. Lift out Diaphragm.
3. Remove Demand Tube.
NOTE: Normal maintenance does not require removal
of Regulator Body from Helmet.
Cover and Diaphraagm removed
