without assistance This should be practiced until the pro-
cedure becomes familiar
HELMET REMOVAL:
Release and open the buckle of the Positive Locking
Straps. Release the Neck Ring from the Helmet by fully
opening the Cam Handles. The Helmet can then be re-
moved by grasping the front (near the Regulator) and push-
ing out and up. Removal under normal conditions or in an
emergency can be accomplished in less than five seconds.

OPERATING INSTRUCTIONS
It is recommended that the diver fully acquaint themselves
with all valves, components, and accessories in a training
tank or shallow water before making a working dive.
A thin film of anti-fogging solution (such as liquid dish
soap) may be applied to the inside of the Face Plate to
prevent fogging.
The diver should test radio communications, the Free Flow
and Demand breathing systems, just before the dive.
The -Regulator Adjustment Knob should be adjusted to
prevent free flow.
The umbilical should be hooked to the diving harness with
a suitable snap. (Miller Diving Equipment manufactures a
full line of diving harness and backpacks). Do not attach
the umbilical to the weight belt.
If it is necessary to jump off a high barge or boat, the side
exhaust should be fully closed, the Regulator Exhaust par-
tially closed, and a strong Free Flow turned on. Do not
jump into the water using only the Demand System, as the
impact could force water through the exhausts. Hold on to
the Helmet securely with at least one hand when jumping.
Liberal use of Free Flow Valve will be much more com-
fortable to the diver in a hard working situation. However,
using the demand system is much better for communica-
tion purposes and is essential for economical consump-
tion if using a mixed gas breathing media.
The Helmet should be rinsed with fresh water after each
dive and stored out of sunlight with good ventilation. Store
the Neck Ring separately to allow Helmet to dry out com-
pletely.

EMERGENCY PROCEDURES:
An EMERGENCY GAS SUPPLY should be used for all
diving operations. The emergency gas should correspond
to the breathing media being used for the dive. The supply
should be adequate for a safe return to the surface or div-
ing bell. This must be determined by the diver according
to depth and duration of the dive. In most emergency situ-
ations, it is normally best NOT to remove the diving Hel-
met unless absolutely necessary. Communication with sur-
face personnel may aid in rapid restoration of lost gas sup-
ply.
Several safety harness/back pack combinations are manu-
factured by Miller Diving Equipment for mounting emer-
gency gas cylinders and attaching the main umbilical to
the diver.
The gas cylinder must be equipped with a first stage regu-
lator and a hose. The first stage regulator used on the emer-
gency gas cylinder should be equipped with a pressure re-
lief valve (pop off valve), in the event the first stage regu-
lator develops a leak that could overpressure the hose lead-
ing to the Helmet.
The hose is connected to an Emergency Valve which is
installed in the Emergency Valve Elbow on Free Flow
Manifold Valve.
