WARNING
The one way valve must be tested daily, prior
to the commencement of diving operations.
Failure of the one way valve could cause se-
rious injury or death. Follow the procedures
for testing the valve in this manual.
The emergency gas comes from a tank of compressed
gas worn by the diver. It enters the system through
the Emergency Gas valve when the diver turns the
control knob on. The flow then enters the side block.

DANGER
Never connect the main gas supply hose from
the diving station/umbilical to the emergency
valve. There is no one way valve in the emer-
gency valve. If this mistake is made, any break
in the supply hose could possibly result in a
“squeeze”.
This could result in serious injury or death.
Both sources of gas flow through the same passage in
the side block body to two exits. One exit is always
open to supply gas to the demand regulator assembly.
The other exit is to the defogger valve (free-flow
valve) assembly.
The diver controls the flow of gas through the defog-
ger system with the control knob. The gas enters the
helmet and flows through the air train which directs
the gas onto the face port to help eliminate or clear
fogging of the faceplate that forms from the diver’s
warm breath.
The flow continues out through the water dump (hel-
met exhaust) valve, or into the oral nasal by means
of the valve, then into the regulator and out through
the regulator exhaust to the Tri-Valve
®
whiskers. The
diver can breathe from this flow of gas if the demand
regulator malfunctions.
Returning to the side block assembly: the other pas-
sage for gas is to the demand regulator. It goes to a
bent tube assembly that connects to the inlet nipple of
the demand regulator. The flow of gas in the demand
regulator assembly is controlled by the inlet valve
that supplies gas to the diver on inhalation “demand”
only, and shuts off during the exhalation cycle.
The SuperFlow
®
demand regulator senses the start
of the divers inhalation and opens the inlet valve,
matching the diver’s need. The regulator continues
to match the diver’s inhalation as the rate increases,
peaks, then ebbs and stops. When the diver exhales,
the supply gas stays off as the exhalation gas flows
through the regulator body, out the regulator exhaust
valve, through the Tri-Valve
®
whiskers, and out into
the water. The whiskers deflect the exhaust bubbles
away from the face port to keep the diver’s view clear.
All KMDSI Helmets and Band Masks are equipped
with a multi-turn demand regulator adjustment
knob. This adjustment knob allows the diver to
make corrections to compensate for a wide range
of incoming gas supply pressures. See “Appendix 3
Supply Pressure Requirements & Tables” on page
146 regarding appropriate supply pressures.
The adjustment knob operates by simply increasing
or decreasing the amount of spring bias tension on the
demand regulator inlet valve. The adjustment knob
has a range of approximately 13 turns from full in
to full out. The intent of this bias adjustment device
is strictly to allow the diver to make adjustments for
variations in umbilical supply pressure.
This adjustment device is not intended as a minimum-
maximum device. Minimum and maximum applies
to supply pressure only. The adjustment knob should
be adjusted by the diver to be at the easiest breath-
ing setting at all times. The exact number of turns
required is dependent on the supply pressure.
Diving a KMDSI helmet or bandmask with a bias
setting greater than that just necessary to keep the
demand valve from free flowing increases the work
of breathing and reduces the diver’s ability to perform
heavy work.
