Contaminated Water Diving; Cold Water Diving - Tusa RS-790 Manual Del Propietário

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 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.

CONTAMINATED WATER DIVING

Sophisticated diving gear designed for use in contaminated water provides constant
positive pressure inside the regulator case and utilizes redundant exhaust valve
passages. TUSA regulators are not designed to provide this requirement and
therefore are not recommended for use in contaminated water diving.
