  • kwang:

    Hi! I have some questions about the scuba Equipment im about to order. Im looking for full scuba gear including BC Jacket, Regulator, Octo, Diving Computer, and Dry Suit. And my question is if i order all of them here, is it possible for u guys to assemble it all together and send it to me so i can use it right away? If yes do i have to buy hoses, which connect regulator to dry suit and octo, seperatly or does it come with it? please let me know if its possible. Thank you.

    Hello Kwang, yes we would attach all of your hoses to your first stage so when you get your gear you are all ready to go diving.

And if u guys dont do assemble there, can u guys send me a manual so i can assemble it by myself? And which parts, otherthan BC Jacket, Regulator, Octo, Diving Computer, and Dry Suit, do i need to buy to assemble it? Thank you.

    Hello Kwang, if you already have a dry suit then you would need to attack your power inflator to your 1st stage.

The RS-530 regulator is one of the latest TUSA first and second stages that delivers excellent quality in an affordable, lightweight, travel-friendly system.

The balanced piston R-500 first stage is incredibly small and weighs only 720g. It has a full complement of four low-pressure and two high-pressure ports and is equipped with a quick adjustment screw that can easily be tuned for optimum performance.

Ortho-consciously designed mouthpiece
The new mouthpiece further enhances the comfort of bite, fit, and stability. Even with a light bite, a high level of stability is achieved so there is no fatigue from long periods of usage.

Breathing resistance adjustment knob
Respiration rate and air consumption rate vary greatly while diving according to environmental conditions (water depth, current, etc.) as well as the skill and physical condition of the diver. A necessary condition for safe and pleasant diving is natural breathing in correspondence to the circumstance at any given time. With the S-30 you simply rotate the flow adjustment knob on the side with its ideal click feeling for free control of the air supply volume according to your needs. The multiple thread screws permit speedy and fine adjustment from which you can appropriately sense resistance to exhaled air, to a condition in which you feel almost no resistance.

PRE-DIVE PROCEDURES
WARNING
Do not attempt to connect low pressure hoses to the high pressure ports with the use
of an adapter. Improper connection will cause damage to the equipment and could
result in serious personal injury. Low pressure components are not intended to
withstand pressures greater than 28Bar ≒(400 PSI). When installing your accessory
hoses, avoid damaging the O-ring. Tighten gently, but firmly into the first stage housing.
SCUBA complying with EN 250 are not intended for more than one user to breathe from
at the same time.
If SCUBA are configured and used by more than one diver at the same time, then the
cold water and breathing performances may not fulfil the requirements of EN 250.
RS-350, 340
Always connect the Octopus Regulator to the portmarked with SS. Connecting to any
other port is strictly prohibited.
PRE-DIVE OPERATING INSTRUCTIONS
1. Position the tank valve so the outlet points toward the diver.
2. Remove the dust cap from the first stage inlet and place the yoke (or DIN adaptor)
in the center of the cylinder valve connection.
3. Position the first stage body so that the second stage hose goes over the right
shoulder of the diver.
4. Hand-tighten the yoke screw or DIN adoptorscrew.
5. Check all the hose connections to the first and second stages. If they can be
loosened by hand, they should be tightened with a wrench before pressurizing.
6. Check the submersible pressure gauge to make sure it indicates zero pressure.
7. Open the tank valve slowly to gradually allow air into the regulator.
NOTE: During this operation, depress the second stage purge button to reduce
shock to the valve mechanism. Do not perform this operation in a cold environment
below 10°C (50°F). Performing this in a cold environment may cause “freeze-up” of
the regulator which can render it inoperable. If this occurs, you should contact a
TUSA authorized service center.
8. Check the submersible pressure gauge to ensure that it indicates the proper tank
pressure.

9. Check the tank/regulator connection for leakage. If leakage exists, it may be caused
by incorrect mounting of the regulator on the tank valve, or by a damaged O-ring in
the tank valve.
10. To confirm that the regulator delivers air properly, first exhale through the
mouthpiece to blow any foreign matter out of the second stage, then inhale. A few
of these breathing cycles should immediately indicate proper function.
11. If you are using the second stage as an Octopus regulator, it is strongly recommended to utilize an Octopus plug to prevent any foreign matter from entering the
second stage through the mouthpiece.
12. When the second stage is not in your mouth, uncontrolled air delivery can take
place. This can be stopped by turning the second stage upside down and allowing
it to fill with water. Should the air delivery continue, abort the dive and have the
regulator inspected by a TUSA Authorized Service Center.

AFTER DIVE PROCEDURES

Providing the best possible preventative and routine maintenance before, after, and
between dives will help to ensure the maximum life of your TUSA Regulator. To achieve
this goal, there are a number of simple, yet important, routine maintenance procedures
that should be followed by the diver after each use of the equipment. The following
procedures should be diligently followed in order to obtain the maximum life and
serviceability from your regulator.

1. After each day of diving, the regulator must be cleaned, inspected, and prepared for
the next use, or for storage. As soon as the regulator is removed from the air
cylinder, reinstall the dust cap over the regulator inlet port. This cap is normally
attached to the First Stage and therefore has been under water. Be sure to dry all
the water out of this cap before securing it over the inlet port. Ensure that the O-ring,
if fitted, is in place inside the dust cap.

2. As soon as possible after diving, the regulator should be soaked in warm, not over
50°C (122°F) water to remove salt and mineral deposits.The preferred method is to
attach the regulator to a charged air cylinder, open the cylinder valve, and
thoroughly soak both the first and second stage regulators . Pay particular attention
to directing water into the mainspring cavity of the first stage regulator, the second
stage mouthpiece, and the holes in the second stage cover. Depress the purge
button several times while the regulator is submerged in water. Dry the regulator by
pressing on the purge button with the mouthpiece pointing down. Place the dust cap
in position in the yoke, or over the DIN screw.

Soaking regulator parts in warm water will remove more salt and mineral deposits
than will conventional rinsing. It will loosen deposits on interior components that
rinsing will not (If no charged air cylinder is available, follow the above procedure but
be very careful NOT to depress the purge button, or leave dust cap off, when the
regulator is submerged in water. Failure to do this will allow water to enter both
regulator stages and may result in internal corrosion).
Simply soak the entire exterior of the first stage thoroughly, and proceed as above
when cleaning the second stage.

3. Store in a clean equipment box, or as an alternative, seal inside a plastic bag. Store
in a clean dry place.
4. Lightly lubricate the yoke screw with silicone grease.
5. Never store the regulator while it is still connected to the diving cylinder.
6. Do not use any type of solvent to clean any part of the regulator. Do not expose any
part of the regulator to silicone spray, as some aerosol propellants attack or degrade
rubber and plastic material.
7. Do not carry the diving cylinder by the regulator as such abuse will eventually
damage the regulator or the cylinder valve. Do not expose the regulator to
unnecessary shocks or impact.
