WARNING
If the mask is used for surface supplied diving, do not
connect the umbilical directly to the M-48 SCUBA pod
regulator. This can create a direct pull on the mask and
pod and does not allow for use of a one-way valve and
EGS supply. Always connect the umbilical to a one-way
valve on a manifold block assembly, which then can be
properly secured to the diving harness. KMDSI Manifold
Block KMDSI P/N 300-145, 300-150, or 300-155 is appropri-
ate for this purpose. Use of the manifold block requires
surface supplied training.
Without the proper equipment for surface supply, the risks
are many and can include: severe face squeeze, loss of
mask, separation from air hose/umbilical, all of which can
result in severe injury or death by drowning.
The minimum temperature for using the Balanced SCUBA and M-48
SuperMask
®
with a surface supply umbilical and KMDSI manifold block is
32 °F (0.5 °C).
B
WARNING
When diving surface supply using a high pressure source,
use only a high pressure source that has been filtered
through a system that removes moisture down to at least
-50 °F (-45 °C) to reduce the possibility of forming ice in
the supply system. Ice has the potential to dangerously
restrict or cut off a diver’s air supply, resulting in serious
injury or death.
Surface Supplied Open Circuit Diving Mode
The SuperMask
®
can be used for surface supplied diving when used with
a surface supplied diving system.
When using the KMDSI SuperFlow
®
and Balanced SCUBA regulator second
stage, the mask can be used to depths of 130 FSW (39 msw) when sup-
plied with an air source capable of delivering at least 4.5 actual cubic feet
of air per minute (acfm) (127 alpm) to the diver worn manifold assembly.
An ordinary scuba regulator first stage connected to a diving cylinder on
the surface with a long hose to the mask is not an acceptable arrangement
for this purpose, no matter what type of regulator is used.
