3. PREPARATION AND CONFIGURATION
TDS recommends that you take your regulator to a TDS Licensed Technician for the
installation of any ancillary elements, including instrumentation, LP quick discon-
nect hoses, and alternative air sources.
CAUTION: when the user assembles or disassembles the SCUBA device, that could cause
damage to the product and subsequently cause injury to the diver.
3.1 ASSEMBLY OF THE FIRST STAGE IN THE BOTTLE VALVE
3.1.1 INT TYPE CONECTOR
1.- Partially loosen the first-stage regulator yoke screw so that the filter dust cap
and air inlet can be removed.
2.- Remove the protective cover of the bottle valve.
3.- With the bottle valve outwards, release a small amount of air from the bottle by
turning the steering wheel counterclockwise to open the valve only slightly. When
you hear air coming out, immediately close the valve. This will remove any moisture
or dirt that may be inside the outlet opening of the bottle valve.
4.- Check the condition of the O-ring of the bottle valve.

5.- Place the 1st stage on the valve of the bottle so that the inlet attachment aligns with the
O-ring of the bottle valve and the LP hose of the 2nd primary stage will be routed over the right
shoulder. While holding the 1st stage in place, turn the INT screw in a timely direction. Make sure
the fork screw is attached to the small dimple on the back of the bottle valve and tighten only
with your fingers.
3.1.2 DIN TYPE CONNECTOR
1.- Remove the protective cover of the bottle valve.
2.- With the bottle valve outwards, release a small amount of air from the bottle by turning the
steering wheel counterclockwise to open the valve only slightly. When you hear air coming out,
immediately close the valve. This will remove any moisture or dirt that may be inside the thread
bottle valve opening.
3.- Check the status of the O-ring located at the end of the DIN connector.
4.- Place the regulator of the first stage near the valve of the bottle so that the LP hose of the
second primary stage is routed on the right shoulder. Screw the DIN connector of the first stage
into the bottle valve, turning the steering wheel by hand in a timely direction until it is slightly
adjusted. DO NOT use tools to tighten.
3.2 PRE-DIVE VERIFICATIONS
1.- Carefully inspect all hoses in their connections to ensure that they are securely connected
to their respective ports in the first stage. Inspect the length of each hose to make sure the
hoses are not blistered, cut, or damaged. If there are hose protectors, slide the protectors back
to expose the hose fittings and inspect the hoses as described above.
2.- Visually inspect the regulators, the first and second stage to detect signs of external
damage.
3.- Visually inspect the nozzle to make sure that there are no tears or cracks and that it is well
attached to the body of the second stage.
4.- Check that the needle of your submersible pressure meter is at zero.
5.- Adjust your regulator to the bottle, verifying that the hoses are oriented correctly.

3.3 PRESSURIZE REGULATOR
WARNING: Before pressurizing the regulator, check the condition of the hoses connected to the
regulator.
1. If there is a submersible pressure meter connected to the regulator, make sure the meter dial
is away from you.
2. SLOWLY open the bottle valve counterclockwise to pressurize the regulator. When the valve is
fully open, close it back a quarter turn clockwise.
3. Check for no audible leaks from hoses or other accessories connected to the regulator. NEVER
DIVE with a regulator that shows signs of leakage when pressurized. If there is a leak between
the regulator and the bottle valve, verify that the regulator is properly connected, and that the
O-ring is in good condition.
CAUTION: Never attempt to reposition the hoses once the regulator is under pressure. If they are not orien-
ted correctly, close the bottle valve, purge the regulator, and replace the hoses.
4. Check to make sure that the submersible pressure meter shows an accurate measurement
of the air pressure inside the bottle at the time of loading and is appropriate for your planned
immersion.
5. Press the purge button momentarily to make sure enough airflow is provided to expel any
dust or dirt that may have entered the second stage.
6. Inhale slowly and deeply from the regulator several times. The regulator must deliver enough
air so that it can breathe easily without noticeable resistance.
NOTE: When properly maintained, the external diaphragm of the proteus and GULL first-stage regulator
should be slightly indented when not pressurized. When pressurized, the external diaphragm will flex slightly outwards.
4. DIVING WITH THE REGULATOR
4.1 USE AS OCTOPUS
If a regulator such as octopus is to be used, it is recommended to cover the nozzle to prevent the
intrusion of foreign objects into the second-stage octopus.
While underwater, the regulator can begin to flow freely. If this happens, turn the regulator so
that the nozzle points down.

4.2 DIVING IN COLD WATER
The use of a specialized regulator with a dry environmental chamber will reduce the possibility
of failure of the first stage of the regulator. It is also vital to use a second-stage regulator inten-
ded for this type of diving. In addition, the diver must be trained and master the techniques
of diving in cold water to be able to take all the necessary precautions to avoid freezing the
regulator.
To reduce the regulator’s freezing risks when diving in cold water (below 50°F or 10°C), consi-
der at least the following recommendations and respect the procedure of your diving training
program:
1. Protect your regulator from any accidental inflow of water in the first or second stage.
2. Protect your equipment from the cold before immersion. More accurately, keep your regu-
lator and all your accessories in a warm, dry place.
3. Perform all pre-dive checks of your equipment in a hot and dry place, even before going to
the dive site.
4. Avoid breathing through the regulator or pressing the purge button in very cold air before
entering the water.
5. Avoid removing the regulator from your mouth during immersion or when on the surface.
This will prevent cold water from entering the second stage of the regulator.
6. As far as possible, avoid excessive effort during immersion.
7. Check your air source to make sure it meets Grade E standards and is dry.
5. AFTER THE DIVE
5.1 REMOVAL OF THE REGULATOR IN THE BOTTLE
NOTA: If fresh water is available, rinse your regulator completely before depressurizing it.
This will help prevent contaminants from entering the sealing surfaces inside the regulator.
NOTA: It is very important to be careful when removing the first stage of the valve regu-
lator from the bottle to ensure that no moisture enters the inlet opening of the first stage of
the regulator or the opening of the DIN valve.

5.1.1 GENERAL PROCEDURES
1. Close the bottle air supply by turning the bottle valve flywheel on a timely direction until it
stops. DO NOT squeeze it too much.
2. While observing the submersible pressure gauge (if equipped), press the button and purge
the second stage. When the meter reads zero and the airflow can no longer be heard from the
second stage, release the purge button.
5.1.2 INT TYPE CONNECTOR
1. Turn the yoke screw counterclockwise to loosen and remove the first valve cap from the bottle.
2. Dry the dust plug with a towel or other lint-free cloth. While you can use air from the bottle
valve to blow water from the dust cap, you run the risk
of blowing water into the filter.
3. Place the dust plug over the first stage entry accessory and seal it firmly in place by squeezing
the yoke screw
4. With the bottle valve out, open the valve slightly to release a small burst of air and then close
the valve immediately. This will remove any moisture that may have entered the valve opening.
Immediately place the protective cap over the valve opening to prevent moisture or debris from
entering.
5.2 CLEANING
TDS recommends that the 2nd stage be periodically disinfected with an FDA-approved solution.

6. CARE AND MAINTENANCE
It is important to provide proper preventive maintenance to ensure the best possible perfor-
mance and maximum service life of your ODS regulator. The following maintenance procedures
should be performed routinely after each use to ensure that the regulator is cleaned, inspected,
and prepared for next use or for storage.

1212
TDS Technical dive system ■ 12
www.cascoantiguo.com | www.tdsdive.com 1ST Stage - 2ND Stage - Octopus
As soon as possible after diving, the regulator should be rinsed completely with fresh water whi-
le connected to a bottle and pressurized with air.
Rinsing alone, however, will not clean up the regulator sufficiently. In order to clean up the con-
troller as thoroughly as possible, TDS recommends:
1. Connect the regulator to a loaded SCUBA bottle, open the bottle valve to pressurize the regu-
lator and fully immerse the first and second stages in a freshwater bath.
2. After the regulator has been properly soaked, it is important to rinse it vigorously by rinsing
the main spring cavity of the first stage regulator (only environmentally unsealed models), the
second stage nozzle and the openings in the front cover of the second stage with a strong
stream of water. This will remove salt and mineral deposits that were released during soaking.
WARNING: If you use a garden hose to clean it, DO NOT use the high pressure jet as this could damage the
diaphragm and/or internal valve.
CAUTION: Do not press the purge button or loosen the int of the first stage if the regulator is submerged
without pressure. Doing so will allow moisture to enter and will require the regulator to be returned to an Authori-
zed TDS Technician for repair.
3. Properly disconnect the regulator and clean it as dry as possible. Take it into the first stage to
make sure all remaining moisture drains from the second stages and accessories.
4. DO NOT leave the regulator exposed to direct sunlight for extended periods of time.
5. When the regulator is completely dry, store it in a box of clean or sealed equipment inside
a plastic bag. Do not store it where you may be exposed to extreme heat or an electric motor,
which produces ozone. Prolonged exposure to extreme heat, ozone, chlorine and ultraviolet rays
can cause premature degradation of rubber parts and components.
6. Never store the regulator while it is still connected to the bottle valve.
WARNING: Do not use any type of solvent or petroleum-based substance to clean or lubricate any part
of the regulator. Do not expose any part of the regulator to aerosols, as some aerosol thrusters attack or degrade
rubber and/or plastic components.

Instructions - User’s manual ■ 13
7. INSPECTION AND SERVICE
It cannot be assumed that a regulator is in good working order because it has received little use
since it was last reviewed. Remember that prolonged or inadequate storage can still lead to in-
ternal corrosion and/or deterioration of O-rings.
You must obtain the factory-prescribed service for your regulator at least once a year from an
authorized TDS Technician, regardless of the amount of use you have received. Your regulator
may require this service more frequently, depending on the amount of use you receive and the
environmental conditions under which it is used.
If the regulator is used for training purposes, it will require a full review and prescribed service
at the factory every three to four months. Chlorinated pool water is an especially harmful envi-
ronment for diving equipment, due to high levels of chlorine and pH-balancing chemicals that
cause certain components to deteriorate rapidly.
Get service for your regulator at least once a year, from an authorized TDS technician. Your per-
sonal safety and the mechanical integrity of your regulator may depend on it.
7.1 SCHEDULED SERVICE EXCEPTIONS
If the regulator undergoes less than 50 dives per year, it is allowed to review it every two years
with an inspection procedure that is performed in the “inactive” years. For example:
• Year 1: Inspection
• Year 2: Review
• Year 3: Inspection
• Year 4: Review, and so on.
• Both inspections and reviews must be documented in the Annual Inspection and Service Re-
gister on the back of the Owner’s Manual. If a regulator is subject to more than 50 dives per year,
it should receive the full review.
NOTE: A unit that receives intensive or frequent use, such as in educational or commercial applications,
must be serviced at least twice a year, or more frequently, depending on the conditions of use and the way it is
maintained.
