Questions and Answers for TUSA X-PERT RS-460 II Regulator:


  • chrisse:

    Does the air flow adjuster, regulate the amount of air flow that you want or is it for preventing unwanted free flow?

    Bob  (Certified Scuba Instructor at Scuba.com):

    It serves both functions.

  • Thomas:

    How much does it weigh?

    Bob  (Certified Scuba Instructor at Scuba.com):

    A little bit over 3 pounds.

The R-400 First stage features a balanced diaphragm system and upgraded HP poppet assembly for enhanced reliability. This balanced diaphragm system maintains minimum variation in intermediate pressure in relation to changes in residual tank pressure. The first stage features two high flow low-pressure ports to optimize second stage performance for easier breathing.

The S-60 second stage features a diver adjustable sensitivity control to deliver air smoothly with each breath. The exhaust valve features a large and flexible design for extremely low exhaust resistance.

Balanced diaphragm type first stage (R-400):
Upgraded with a new poppet assembly for 2008-09, the balanced diaphragm system features a minimum variation in intermediate pressure in the relation to changes in residual tank pressure. The diaphragm first stage also offers excellent performance in all water conditions due to its sealed design.

High flow low pressure ports:
Two high flow ports are engineered for the smoothest air delivery possible to the primary second stage and octopus at all tank pressures.

Cold water insulation system:
The R-400 first stage features a special coating on the main spring to ensure that the regulator performs in all diving conditions. Available in Yoke or 300 bar DIN:
The first stage can be converted from a yoke connection to a 300 bar DIN connection.

Adjustable surface or diving sensitivity control:
The 'Surface' or 'Dive' control allows the user to set the ease of breathing for varying sections of the dive. The surface position decreases the likelihood of a free flow and also is recommended for cold water diving. In the dive position the control allows the regulator to power assist the diver as they breathe using the venturi effect.

TUSA Regulators are BALANCED PISTON and BALANCED DIAPHRAGM type SINGLE HOSE REGULATORS. The regulator reduces high pressure air from the scuba
cylinder to ambient pressure suitable for breathing, through the operation of fi rst and
second stage regulators. The fi rst stage regulator reduces incoming high pressure
air, to an intermediate pressure of approximately 135PSI ( 9.5bar). The second
stage regulator, using a diaphragm operated demand valve, further reduces air from
intermediate pressure to ambient pressure permitting normal breathing. The fi rst and
second stages of the regulator are connected by a low pressure hose. A swivel yoke
(TYPE INT) on the fi rst stage body secures the regulator to the cylinder valve, while
an O-ring surrounding the outlet orifi ce on the cylinder valve ensures an airtight connection to the fi rst stage.

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.

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.

FTER 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.
