Use Of Conventional Regulators; St Stage Sl 35Tx - Ocean Reef NEPTUNE SPACE PREDATOR Owner's Manual

temperature range of operations between -40°C and 70°C (-40°F and 158°F).
The purge button protection bezel is made of a high impact-resistant
double metallized/coated techno polymer.

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 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.
1ST STAGE SL 35 TX
The Neptune Space Predator may be used only with this high performance,
balanced diaphragm 1st stage with anti-freeze kit. The first stage has
