Oceanic Regulator
REGULATOR FIRST STAGES
WARNING: Failure to prepare your First Stage properly for use in
harsh environmental conditions, such as being subjected to sedi-
ment or the possible buildup of ice, or salt crystals, may result
in serious injury or death.
Operation of your first stage is not visible when using a regulator. The first
stage converts the tank's high pressure air to an intermediate pressure of ap-
proximately 140 psi that can be handled by the regulator second stage to de-
liver a smooth flow of breathing gas upon demand (i.e., when you inhale). In-
termediate pressure gas is also available for inflation of a BC or dry suit.
WARNING: Under no circumstances should adjustment of an
Oceanic first stage regulator be performed by anyone other than
an Authorized Oceanic Dealer. Doing so may cause failure under-
water, resulting in serious injury or death.
ATTACHMENT OF HOSES
Low pressure (LP) and high pressure (HP) port thread sizes are different, making
incorrect installation of hoses unlikely. However, to avoid damage or personal
injury that may occur due to incorrect installation, Oceanic strongly recommends
having installation performed professionally by an Authorized Oceanic Dealer.
If this is not possible, proceed as follows.
Type of Hose Being Connected:
 Determine whether the hose that you are installing requires connection to an
HP port (for a pressure gauge or breathing gas integrated computer), or to
an LP port (for an octopus second stage, or a BC or dry suit inflator).
 Be sure that you only place high pressure accessory hoses in ports specifi-
cally marked with the letters 'HP', or '4500 psi / 300 BAR'.
Orientation (positioning):
Orientation is defined by the location of the LP ports when the first stage is
mounted on the tank valve. Mounting the first stage so the LP ports are lower
(closer to the tank) than the HP ports is referred to as the DOWN position.
Mounting the first stage so the LP ports are higher (further away from the tank)
than the HP ports is referred to as the UP position.
Using the DOWN position produces the lowest overall regulator/tank profile, re-
ducing the possibility of your head coming in contact with the first stage during
your dives. Also, in the DOWN position, the venturi assisted LP port will be po-
sitioned so that the primary second stage is on your right side.
By mounting a first stage, such as the PX2, that utilizes a swivel section for the LP
connections in the UP position, you can obtain greater accessibility to your
hoses due to the swivel being positioned approximately 4 inches higher than in
the DOWN position.
