Oceanic Regulator
INTRODUCTION
THANK YOU for choosing a regulator product from Oceanic!
Features and operation of the various models of Oceanic regulator first and sec-
ond stages currently available are described in this owner's guide, and/or any
addendum or supplement provided with it. By following the instructions in this
guide, you will understand how your regulator product works, how to make best
use of its features, and how to maintain it for long term use. Some information
presented may not be applicable to the specific model of regulator or accessory
that you purchased. DO NOT dive with the regulator until you have read and
understand all information provided with it.
STATEMENT FOR
OCEANIC RE ULATOR EQUIPMENT
COMPATIBILITY AND USE WITH NITROX
Unless specifically labeled otherwise, Oceanic Regulator equipment is classified
as being suitable for use with nitrogen-oxygen (Nitrox) breathing gas mixtures
containing up to 40% oxygen by volume without the need for special prepara-
tion, cleaning , or component parts.
If Oceanic Regulator equipment is subsequently used with equipment, or con-
nected to an air supply system, that is not rated for Oxygen Service, it can sub-
sequently be used with Nitrox (up to 40% O2) as long as it is maintained in ac-
cordance with the procedures and parts specified in the Oceanic Product Ser-
vice Guide.
WARNIN S:
Oceanic Regulators are not intended to be used by untrained per-
sons who may not know the inherent risks and hazards of SCUBA
diving.
Prior to use of Oceanic Regulator equipment with nitrogen-oxygen
(Nitrox) breathing gas mixtures that contain a higher fraction of
oxygen than 21%, the user must have received, or must first ob-
tain, certification in diving with Nitrox from a recognized training
agency.
An Oceanic Regulator is not a medical device. It is not intended
and must not be used to supply treatment oxygen in a medical
emergency.

5
Owner's uide
NOTE: The term breathing gas used throughout this owner's
guide applies to enriched nitrogen-oxygen (Nitrox) mixtures as
well as compressed Air.
When using Air with this regulator equipment, the Air used must
meet EN132 Annex A standards.
STATEMENT FOR
OCEANIC RE ULATOR EQUIPMENT
COLD WATER DIVIN
All Oceanic Regulator First Stages are classified as being suitable for use in wa-
ters having Temperatures of 50°F (10 °C) and higher.
Due to operational limits, use in waters having colder Temperatures requires
Oceanic Diaphragm style First Stages to be properly fitted with an Environmen-
tal Protection Kit to prevent the possible buildup of ice crystals in the Spring Cav-
ity.
Due to the inherent design of Oceanic Piston style First Stages, they cannot be
specially prepared to accomodate the operational limits imposed by waters hav-
ing Temperatures below of 50°F (10 °C). Oceanic therefore recommends the
use of Diaphragm style First Stages fitted with Environmental Protection Kits
when diving in waters having lower Temperatures.
WARNIN : Installation of an Environmental Protection Kit must
be performed by the Oceanic factory or an Authorized Oceanic
Dealer. Improper installation may cause First Stage failure while
underwater resulting in serious injury or death.
Specialized training and skills required for cold water diving will reduce effects
that cold water Temperatures can impose upon the operation of Oceanic
Regulator Second Stage(s).
WARNIN : Failure to obtain proper training in the specialized
techniques required for diving in cold water environments and
failure to apply such techniques to handle situations that could re-
sult in Regulator freezing will place you in risk of serious injury or
death.

Oceanic Regulator
REGULATOR FIRST STAGES
WARNIN : 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.
WARNIN : 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.

7
Owner's uide
The convenience of two HP ports provides for consistent positioning of your in-
strument console regardless of the orientation of the first stage. Note that the
SP4 and Explorers only have one HP port.
Experience and experimentation will be your best guide to choosing the orienta-
tion that is best to satisfy your needs and preference.
Installing Hoses:
After having determined the type of hose and preferred orientation -
 Remove the port plugs from those ports to be used by turning them counter
clockwise with a 5/32" hex key. Save the port plugs for possible future
use.
 Lightly lubricate the hose-end threads and o-ring with Christo-Lube
MCG111 lubricant (silicone grease is acceptable only if the regulator is not
designated for use with nitrox).
 Thread the hose clockwise into the port until secure, then tighten it with an
open end wrench of the appropriate size to a torque of 40 in-lbs.
  Second stage - 9/16" wrench
  LP inflator - 9/16" (or 1/2") wrench
  HP gauge or integrated computer - 5/8" wrench
 After all hoses are connected, test the complete regulator assembly by at-
taching it to an appropriate tank, pressurizing the system, and carefully lis-
tening for leakage of breathing gas.
REMOVAL OF HOSES
WARNIN : At least one second stage must be connected to the
first stage to facilitate purging of breathing gas from the first
stage.
To remove a hose from the first stage -
 Loosen and remove the hose by turning it in the counter clockwise direction
with an open end wrench of the appropriate size.
 Lightly lubricate the threads and o-ring of the port plug.
 Thread the port plug clockwise into the port and tighten to a torque of 40
in-lbs using a 5/32" hex key.
 Test the assembly by attaching it to an appropriate tank, pressurizing the
system, and listening for leakage.
DATALINK
DataLink is a high pressure quick disconnect designed to offer additional protec-
tion for your instrument console. It allows you to quickly and easily remove the
HP hose and instrument console from the regulator first stage without any tools.
It should be oriented so it is best protected from collisions with objects while un-
derwater. DataLink can be purchased from an Authorized Oceanic Dealer.
WARNIN : Proper installation of the DataLink is essential for it to
function properly. It must be installed only by an Authorized Oce-
anic Dealer.

8
Oceanic Regulator
Connecting Your Console with a DataLink:
 Ensure that the regulator system is purged of all breathing gas.
 Push the hose portion of the disconnect firmly into the first stage portion.
 While holding the two portions together with one hand, turn the locking
ring of the first stage portion clockwise (as viewed from the first stage) until
it stops (hand tight). DO NOT overtighten or use tools.
Disconnecting Your Console with a DataLink:
 Ensure that the regulator system is purged of all breathing gas.
 While holding the hose portion of the disconnect with one hand, turn the
locking ring of the first stage portion counter clockwise (as viewed from the
first stage).
 Using care not to bend the DataLink parts, pull the two portions of the quick
disconnect straight apart to remove the HP hose and instrument console.
NOTE: Once the DataLink has been disconnected, the regulator
system can again be pressurized.
RE ULATOR ATTACHMENT TO A TANK
WARNIN : Maximum working pressure for an Oceanic Yoke style
connector is 3500 PSI / 232 BAR and for a DIN style connector is
4500 PSI / 300 BAR
YOKE STYLE CONNECTOR
Before attaching the Regulator to the tank:
 Slowly open then close the tank valve for a second to allow a momentary
flow of breathing gas to blow any moisture or contaminants from the
breathing gas opening in the tank valve.
 Examine the sealing o-ring located on the tank valve to ensure that it is not
cut, frayed, or deteriorated. Replace the o-ring if it is damaged.
To attach the Regulator to the tank:
 Remove the dust protector from the yoke by turning the easy-grip knob in a
counter clockwise direction.
 Place the yoke connector over the tank valve, positioned with the seating
surface against the valve o-ring.
 Turn the easy-grip yoke knob clockwise until secure.
 Slowly open the tank valve (with the pressure gauge facing away from
you).
 Momentarily purge the second stage, then listen to ensure that no breathing
gas is leaking from the regulator/tank connection.
 If any leakage is observed, repeat the attachment procedure and inspect
the sealing o-ring. If gas still leaks, DO NOT USE! Take the regulator and
tank to an Authorized Oceanic Dealer for inspection and service.

9
Owner's uide
If you wish to use your regulator on a DIN tank, have your Authorized Oceanic
Dealer convert the first stage with an Oceanic DIN Conversion Kit following the
procedures given for the specific regulator first stage in the current Oceanic
Product Service Guide.
To remove the Regulator from the tank:
 Close the tank valve and purge all breathing gas from the regulator system
by depressing the purge button of the second stage regulator. Ensure that
all pressure has been purged.
 Turn the easy-grip yoke knob counter clockwise to loosen and lift the first
stage off the tank valve.
 Prevent water from entering the first stage. DO NOT blow breathing
gas near a first stage that does not have the dust protector in
place.
 Dry the dust protector, position it within the yoke, and secure it by tighten-
ing the yoke knob.
DIN WHEEL STYLE CONNECTOR
Before attaching the Regulator to the tank:
 Slowly open then close the tank's valve for a second to allow a momentary
flow of breathing gas to blow any moisture or contaminants from the gas
opening in the tank valve.
 Examine the threads in the valve to ensure they are clean and free of burrs
or defects that could damage the threads of your regulator DIN fitting.
To attach the Regulator to the tank:
 Remove the protector cap from the threads of the regulator DIN connector
wheel, and examine the threads and sealing o-ring. Replace the o-ring if it
is damaged.
 Using care not to cross the threads, thread the DIN connector wheel clock-
wise into the cavity of the tank valve until it is secure.
 Slowly open the tank valve (with the pressure instrument facing away from
you) and listen to ensure that no breathing gas is leaking from the regula-
tor/tank connection.
 If any leakage is observed, repeat the attachment procedure and inspect
the sealing o-ring. If breathing gas still leaks, DO NOT USE! Take the
regulator and tank to an Authorized Oceanic Dealer for inspection and ser-
vice.
If you wish to use your regulator on a standard tank, have your Authorized Oce-
anic Dealer convert the first stage with an Oceanic USA Yoke Conversion Kit fol-
lowing the procedures given for the specific regulator first stage in the current
Oceanic Product Service Guide; or install an Oceanic DIN to USA Converter
Yoke.

10
Oceanic Regulator
To remove the Regulator from the tank:
 Close the tank valve and purge all breathing gas from the regulator system
by depressing the purge button of the second stage regulator.
 Turn the DIN connector wheel counter clockwise out of cavity in the tank
valve.
 Prevent water from entering the first stage. DO NOT blow air near a
first stage that does not have the protector cap in place.
 Place the protector cap on the threads of the regulator DIN connector
wheel.
DIN TO USA CONVERTER YOKE
WARNIN : The DIN to USA Converter is specifically designed for
use with Oceanic brand first stages. Although it may fit other
brand first stages, it was not designed to do so or tested for use
with other brands. Under no circumstances should the Oceanic
DIN to USA Converter be used with any other first stage than an
Oceanic model.
To install the DIN to USA Converter:
 Remove the protector cap from the threads of the regulator DIN connector
wheel, and examine the threads and sealing o-ring. Replace the o-ring if it
is damaged.
 Using care not to cross the threads, thread the DIN to USA Converter clock-
wise onto the first stage DIN connector wheel until it is secure. DO NOT
use tools to tighten.
Before attaching the Regulator to the tank:
 Slowly open then close the tank's valve for a second to allow a momentary
flow of breathing gas to blow any moisture or contaminants from the gas
opening in the tank valve.
 Examine the threads in the valve to ensure they are clean and free of burrs
or defects that could damage the threads of your regulator DIN fitting.
To attach the Regulator to the tank:
 Remove the dust protector from the yoke by turning the easy-grip knob in a
counter clockwise direction.
 Place the yoke connector over the tank valve, positioned with the seating
surface against the valve o-ring.
 Turn the easy-grip yoke knob clockwise until secure.
 Slowly open the tank valve (with the pressure gauge facing away from you)
and listen to ensure that no breathing gas is leaking from the regulator/tank
connection.
 If any leakage is observed, repeat the attachment procedure and inspect
the sealing o-ring. If breathing gas still leaks, DO NOT USE! Take the
regulator and tank to an Authorized Oceanic Dealer for inspection and ser-
vice.

11
Owner's uide
To remove the DIN to USA Converter:
 While holding the DIN connector wheel firmly, turn the DIN to USA Con-
verter counter clockwise off the threads of the first stage DIN connector.
DO NOT use tools to remove.
 Place the protector cap on the threads of the regulator DIN connector
wheel.
ENVIRONMENTAL PROTECTION KIT
By function of design, the inner components of Oceanic diaphragm type regula-
tor first stages (i.e., CDx, DX4) are isolated from the ambient environment.
However, the outer side of the diaphragm and the diaphragm spring, located in-
side the cavity at the hex opening end, will be subjected to environmental con-
ditions.
Oceanic recommends installation of an Environmental Kit on diaphragm type
First Stages (i.e., CDx) subjected to environmental conditions in which debris, or
sediment, or ice, or salt crystals might form in the spring cavity. The kit is a
unique dry seal system that uses no messy grease or chemicals.
Most DX4 first stages are shipped from the factory with the Environmental Kit in-
stalled. If your DX4 (or other model) is not configured with an Environmental Kit,
one can easily be installed by your Authorized Oceanic Dealer.
WARNIN : Installation of an Environmental Kit must be per-
formed by an Authorized Oceanic Dealer. Improper installation
may cause first stage failure while underwater resulting in serious
injury or death.
REGULATOR SECOND STAGES
WARNIN : Even if your First Stage is properly prepared for use
in harsh environmental conditions, only proper training will pro-
tect your Second Stage from the effects of the environment.
FEATURES AND OPERATION
The Second Stage of the regulator assembly receives breathing gas at an inter-
mediate pressure of approximately 140 psi from the first stage and delivers it to
you at ambient pressure during inhalation. When you stop inhaling, it then
shuts off the flow of breathing gas and provides a path for exhaled gas.
All Second Stage regulators have a level of sensitivity that can result in excess
breathing gas being expelled when the Second Stage is not in your mouth while
in the water. When this occurs, it is usually during entry or when on the surface.
This condition, refered to as free-flow, can usually be stopped by turning the
Second Stage so the mouthpiece is pointing down and the purge button is point-
ing up. (See Omega II for an exception to this general feature.)

12
Oceanic Regulator
Recommended is to carry an Octopus with the mouthpiece facing down when
not in use, or to use a mouthpiece plug or cover to prevent free-flow in the event
that it is bumped.
During normal use underwater, a small amount of water collects inside the body
of a standard regulator in a natural reservoir near the bottom. This is normal for
most second stages, and the water is held away from your mouth naturally and
will go unnoticed unless you become inverted or do subaquatic somersaults at
which time you may experience temporary 'wet breathing'.
Water can be purged from the small internal air space of most second stages by
exhaling a small puff of breathing gas into the mouthpiece, or by blocking the
mouthpiece with your tongue and pressing the front mounted purge button to ini-
tiate a flow of breathing gas. (See Omega II for an exception to this general
feature.)
Alpha 7, amma, Pony Bottle, and Explorers (Primary and Octopus)
These models are downstream demand valve second stage regulators that are
lighter and smaller than most other primary second stages. They provide breath-
ing gas as you demand it with low inhalation resistance. Breathing effort is fac-
tory set to the average performance level required by most divers.
They are provided with front-mounted purge buttons and orthodontically de-
signed mouthpieces. They can be used as primary second stages or as on octo-
pus. The Explorers model, designed for children, has a smaller mouthpiece, and
the Pony Bottle second stage has a standard mouthpiece.
NOTE: If these second stages are shipped from the factory spe-
cifically as an Octopus, the inhalation effort is set slightly higher
to reduce sensitivity.
Delta 3 and amma 2 (Primary and Octopus)
Pre-Dive/Dive Switch (on top):
The Delta 3 and Gamma 2 feature a Pre-Dive / Dive switch located on top of
the body.
 Placing the switch in the left ( - ) position (Pre-Dive) reduces, or eliminates,
the possibility of high volume free-flow when the mouthpiece is not in your
mouth.
 Placing the switch in the right ( + ) position (Dive) provides optimum perfor-
mance during a dive.

13
Owner's uide
Delta 3 Adjustment Knob (on side):
The Delta 3 provides a breathing effort adjustment (knob on the side of the
body) that enables you to adapt breathing performance to different diving condi-
tions.
 By turning the adjustment knob 'clockwise' breathing resistance (effort) is in-
creased. This is done to prevent undesirable loss of breathing gas (free
flowing) that often occurs when a high performance regulator second stage
is connected as an octopus second stage, or when the primary second
stage is not in the divers mouth, such as when surface snorkeling.
 Turning the adjustment knob 'counter clockwise' decreases breathing resis-
tance and reduces work of breathing. Adjustment should be used to im-
prove performance, it should not be used as a method to use less breathing
gas. During periods of heavy exertion underwater, and to compensate for
the effects of depth, it is advantageous to have a regulator that can provide
minimal inhalation resistance and optimal performance when desired.
uidelines for Delta 3adjustments (knob on side):
NOTE: Rotation of the Delta 3 adjustment knob does not rotate
the poppet seat against the sealing orifice.
Normal Pre Dive Setting -
 To set the Delta 3 to an average breathing resistance, 1 to 1

column
inches of water (common factory setting), attach the first stage to an appro-
priate cylinder and open the valve to pressurize the regulator.
 Rotate the adjustment knob 'counter clockwise' until leakage is heard, then
rotate the knob clockwise
1
/
2
to 1 turn.
High Flow Setting -
 When diving deep, facing a long swim up current, or during other periods
of heavy exertion, it is desirable to make the Delta breathe as easy as pos-
sible. This setting should be used only when necessary to avoid loss of
breathing gas that may occur due to the Delta's extra sensitivity at this set-
ting.
 To adjust the Delta for minimum breathing resistance, rotate the adjustment
knob 'counter clockwise' until a slight flow of breathing gas begins, then ro-
tate the knob 'clockwise' until the flow stops.
 Frequently monitor your breathing gas supply when the Delta is adjusted for
maximum flow.
Preventing Air Loss -
 To prevent free-flow when the Delta is out of your mouth, or when con-
nected as an octopus second stage, rotate the adjustment knob 'clockwise'
several turns. At the surface, place the Delta 3's Pre-Dive / Dive switch in
the left (-) position (Pre-Dive) to reduce, or eliminate, free-flow.

14
Oceanic Regulator
 Remember, increasing inhalation resistance can prevent undesirable breath-
ing gas loss. It will not conserve breathing gas while you are breathing
from the Delta.
Storage Setting -
 At the conclusion of a diving day, or when storing the Delta for any length
of time, rotate the adjustment knob 'counter clockwise' until it stops. This re-
lieves excess spring pressure from the poppet seat increasing its service life.
 Immediately prior to the next dive, reset the adjustment to the normal pre
dive setting by turning the adjustment knob 'clockwise'
1
/

to 1 turn.
Omega II and Omega II with Swivel
The Omega II is a high performance servo-valve assisted second stage regulator
with a side-exhaust. Inhalation ports surround the main valve, providing greater
surface area, less resistance to breathing gas flow, and higher flow rates creat-
ing more natural, easier breathing than other types of second stages, regardless
of depth.
Due to the Omega II's servo design, a hiss may be heard upon being pressur-
ized. This is normal for the Omega II.
Due to its configuration, there is no natural reservoir to catch and hold any wa-
ter that may enter the Omega II, therefore you may experience a mist of water
that will be constantly expelled. There is no difference in breathing or relative
wetness whether you are upside-down or right-side-up. This makes it ideal as an
octopus.
The unique side-exhaust directs bubbles away from your field of view. Excess
water is expelled by tilting your head to the left (lowering the exhaust valve)
when exhaling.
Upon entering the water, free-flow can occur if the exhaust valve section is
placed in the water before water has a chance to enter the mouthpiece. The
best way to enter the water with the Omega II is with it in your mouth.
If this is not convenient, point the exhaust valve end up and immerse the
mouthpiece first to ensure that water fills the body before pressure is ex-
erted on the diaphragm that may cause it to free-flow.
When planning to resurface, removing the Omega II from your mouth while still
underwater floods the second stage with water, preventing free-flow.
Most Omega IIs are shipped from the factory with a 180 degree Swivel that re-
duces jaw fatigue and provide for the convenience of underarm operation and
ambidextrous operation.

15
Owner's uide
Second Stage Swivel
The low pressure swivel shipped with the Omega II is also available as an ac-
cessory from your Autorized Oceanic Dealer who can install one on any of your
Oceanic Second Stage regulators.
Zeta
The Zeta is a pneumatically balanced Servo-Activated Breathing System. The
highly responsive servo design provides high performance and maximum air
flow at operating depths. The Zeta's purge is designed to control the volume of
air delivered based on the travel of the purge cover.
NOTE: Due to the Zeta's servo design, a hiss may be heard upon
being pressurized. This is normal for the Zeta.
SlimLine Octopus
There are two SlimLine models, left-hand and right-hand. How you use the
SlimLine depends upon the model you chose to suit your preferred arrangement
of equipment and your style of diving (i.e., whether you plan to offer the
SlimLine to a buddy as an alternate breathing gas source or use the SlimLine
yourself, offering your buddy your primary second stage).
Although either model will function properly with the purge button facing up or
down, Oceanic recommends an operational position with the purge button fac-
ing up, similar to other second stage positioning. The streamlined and flat 'side-
ways' design of the SlimLine together with the unique orientation of the mouth-
piece and exhaust valve reduces drag.
Oceanic also offers the SlimLine second stage as an integrated component of
the Air XS II and InLine SlimLine model alternate air source(s).
Swivel 180 Octopus
The Swivel 180 Octo features two conveniently angled exhaust ports that direct
the flow of exhausted breathing gas away from your field of vision. The smoth
action180 degree swivel reduces jaw fatigue and provides for the convenience
of underarm operation and ambidextrous operation.
How you use the Swivel 180 Octo depends upon your preferred arrangement of
equipment and your style of diving (i.e., whether you plan to offer it to a buddy
as an alternate breathing gas source or use it yourself, offering your buddy your
primary second stage).

CARE AND MAINTENANCE
TRANSPORT and STORA E
If possible, transport your regulator assembly (preferably dry) in a padded carry-
ing case or equipment bag separated from sharp items (i.e., dive knife, spear
gun, etc.) that might damage or scratch the components. You should also pro-
tect the second stages from damage from heavy objects ( i.e., dive light, first
stage, etc.).
Prior to storing your regulator:
 Ensure that the complete regulator is clean and dry.
 If you were unable to clean the regulator prior to transport, or if it became
exposed to other equipment that was not thoroughly cleaned prior to trans-
port (such as a BC or wet suit), clean it thoroughly and allow it to dry natu-
rally as previously described.
POST DIVE CARE
As soon as possible at the end of each day of diving:
 Install the first stage protector cap and tighten the yoke knob (or install the
DIN thread protector cap).
 If possible, immerse the entire regulator assembly in a warm fresh water
bath and soak for one hour, preferably while pressurized. DO NOT de-
press the second stage purge button while the regulator is soaking. Doing
so will allow water to flow into the sealed portion of the first stage.
 Remove from the bath and rinse all components of the assembly with slow
running fresh water. DO NOT use full water pressure.
 Flush the ambient openings of the first stage and the exterior of all compo-
nents thoroughly to remove dissolved salt and other contaminants.
 If the first stage is configured with a rubber-like boot, direct rinse water
through the flow-through slots.
 Flush the second stage by running water into the mouthpiece and out the
exhaust ports. DO NOT depress the purge button while rinsing., doing so
will allow water to enter the first stage.
 If possible, lay the complete assembly flat in a cool, dry place (out of di-
rect sunlight) and allow the components to dry naturally.
 DO NOT inject or spray lubricants into or onto the first and second stages.
Doing so can attract contamination that may subsequently interfere with
proper operation.
REPAIRS and SERVICE
WARNIN : DO NOT attempt to disassemble or repair the first or
second stages, or to adjust the first stage. Doing so could cause
malfunction while underwater resulting in serious injury or death.
It will also void the regulator's limited warranty.

Owner's uide
In the event that any component of your regulator assembly requires any form of
repair or service, return it to your local Authorized Oceanic Dealer for profes-
sional service by a trained technician authorized to perform Oceanic factory au-
thorized service.
Once each year your complete regulator assembly should be inspected and ser-
viced by an Authorized Oceanic Dealer. More frequent service is recom-
mended if you dive in severe conditions or more frequently than an average
diver (see guidelines on page 18).
Annual Service consists of:
 Inspection
 Complete disassembly
 Thorough cleaning and evaluation of reusable parts
 Replacement of non-reusable parts
 Complete reassembly
 Final adjustment and testing
Costs for routine inspection and Annual Service are understood to be a normal
part of operation, and are not covered by the regulator's limited warranty.
If Warranty Service is requested, or routine service parts are requested in ac-
cordance with a Registered Service Agreement , present the appropriate
documents (i.e., card, receipts, and service records) to the Authorized Oceanic
Dealer when the regulator is delivered for service.
