CARE AND MAINTENANCE

It is important to provide the proper preventative maintenance in order to
ensure the best possible performance and reliability of the SEA-4500. The
following maintenance procedures should be performed routinely after each
use of the equipment.
1. After each in-water training session, the SEA-4500 must be cleaned, inspected
and prepared for the next use or storage.
2. As soon as possible after training, the SEA-4500 should be soaked thoroughly
for at least one hour in warm (not over 120ºF / 49ºC) tap water to loosen and
dissolve salt (if used in salt water) and mineral deposits. Before soaking, turn
the valve to the "ON" position to pressurize the system. This will best prevent
the entrance of moisture into the system through the second stage.
NOTE: Due to the light weight aluminum first stage, the SEA-4500
is not recommended for continuous use in salt water. The aluminum
first stage is susceptible to galvanic corrosion and needs to be rinsed
thoroughly after use in salt water.
CAUTION:
to ensure that the valve is completely turned to the "OFF" position
and the second stage purge button is not depressed while the system
is submerged or wet. Moisture may otherwise be allowed to enter the
valves and the cylinder, which will require that the system be returned
to a qualified technician for inspection and service.
3. After the system has been properly soaked, it is important to rinse the first
stage, the second stage mouthpiece and the openings in the second stage front
cover with a pressurized stream of water. This will remove the salt and mineral
deposits that were loosened during soaking.
4. When it has been properly soaked and rinsed, wipe the system as dry as
possible with a clean towel and gently shake the first and second stage to
dislodge any water inside them.
5. Check to ensure that the SEA-4500 valve is turned to the "OFF" position
and depress the purge button of the second stage to ensure that the system is
completely depressurized before storing or transporting.
If the SEA-4500 cylinder does not contain air, it is important
