After Dive Procedures - Tusa RS-350 Manual Del Propietário

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 recom-
mended 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.
