Use Of Conventional Regulator; 1St Stage Sl 35Tx - Ocean Reef NEPTUNE SPACE PREDATOR Owner's Manual

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.
The Neptune Space may be used with this high performance, balanced diaphragm 1st stage with anti-
freeze kit. The first stage has adjustable medium pressure and is made of brass with a satin finish
body, stainless steel piston, Teflon seat, and stainless steel spring.
It is available with the following characteristics:
• Standard connection 200 bar (code 9922)
• DIN connection 300 bar (code 9923)
• 2 high pressure ports 7/16 -20 UNF
• 4 Medium pressure ports 3/8-24 UNF
• Flow rate of approx. 4800 l/m at 140 bars
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
PREDATOR 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.
