REGULATOR FIRST STAGES
WARNING: Failure to prepare your First Stage properly for use in harsh en-
vironmental conditions, such as being subjected to sediment or the pos-
sible 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 approximately 140 psi that can
be handled by the regulator second stage to deliver a smooth flow of breathing gas upon
demand (i.e., when you inhale). Intermediate 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 underwater, 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 oc-
cur due to incorrect installation, Oceanic strongly recommends having installation per-
formed professionally by an Authorized Oceanic Dealer. If this is not possible, proceed as
follows.
