USE OF CONVENTIONAL REGULATORS
A special adapter allows the connection of several kinds
of regulators. The adaptor is available in two sizes,
medium (standard) and small. This adapter fits in place
of the surface air valve (code 33020: S, code 33021: M).
USE OF OVER-INJECTED REGULATORS
Over injected regulators have a diaphragm with an
inhalation
cracking
pressure
below
zero.
These
regulators “free flow” easily, and as a result, should not
be used with the Neptune
Space IRON MASK or other
Neptune masks.
Changes in regulator performance can also be caused by
the different positions assumed during a dive;
the use of
a regulator with flow adjustment is recommended.
When descending the adjustment knob must always be turned on to get
the proper air flow. Do not turn off the adjustment knob while
descending.
