SECTION 3
DESCRIPTIONS, MAINTENANCE, AND REPLACEMENT
3-A
HELMET SHELL
DESCRIPTION:
The Helmet Shell is constructed from an approximately
1/4 inch thick, high strength, bronze alloy. The valves
and fittings are all solidly mounted, metal to metal.
MAINTENANCE:
The Helmet should be rinsed off with fresh water after
diving and stored away from the sun. Neck Ring should
be removed to allow inner condensation to evaporate.
Nicks and scratches in the Helmet coating can be spot
repaired with a marine epoxy paint.
DANGER: Never use any aerosol pro-
pelled sprays near the face port of any Miller
diving helmet. The Freon propellant used in
these aerosols can invisibly damage the Clear
polycarbonate face port and cause it to shatter
on impact from any strong blow. If the face port
fails underwater the helmet will flood and drown-
ing may result.
3-B
FACE PLATE AND FACE RING
DESCRIPTION:
The Face Plate is fabricated from 3/16 inch, Polycar-
bonate plate, which is highly impact resistant. Small ex-
terior scratches tend to disappear under water. The Face
Plate is secured by Screws to the Helmet by a bronze
Face Ring with a molded recess for the plate. A silicone
rubber sealant is used to bond the plate to the Helmet.
REMOVAL AND REPLACEMENT:
1. Unscrew the Nose Device Knob.
2. Pull out Nose Device Rod from inside Helmet.
3. Remove the Slotted Nut and Washer.
4. Pull Oral Nasal free from Nose Device Housing .
5. Unscrew and remove Nose Device Housing from
Helmet and Face Ring.
6. Remove all Screws and pry off Face Ring
7. Remove Face Plate from Face Ring.
8. Remove old rubber sealant from Face Ring and Hel-
met by scraping with a blunt screwdriver or scraper. It is
important that these areas are free of old sealant and are
very clean.
9. To install new Face Plate, remove paper from Face
Plate and insert the new Face Plate into Face Ring.
10. Fill the gap between the side of the face plate and the
face ring with silicone.
11. Apply an 1/8" thick bead of silicone sealant com-
pletely around the edge of the face plate.
12. Place Face Ring on Helmet and attach, beginning
with Nose Device Housing. Next, insert one of the up-
per Screws, to align Face Ring. Insert all Screws, but do
not tighten until all are in place. Excess sealant will squirt
out on both the inside and outside of the Helmet when
Face Ring is tightened. This excess sealant can be re-
moved by allowing it to cure for about 20 minutes, then
running a toothpick around the edge, cutting the sealant.
It will then peel off easily.
13. Replace Oral Nasal, Washer, and secure with Slotted
Nut.
14. Replace Nose Device Rod and secure with Nose De-
vice Knob.
NOTE: Certain chemicals and sprays propelled by
Freon can injure and weaken the face plate material.
Do not use solvent or degreaser for cleaning. Use only
warm soapy water.
