22 SEA USER'S MANUAL

Care & Maintenance

It is important to provide the proper preventative maintenance in order to

ensure the best possible performance and reliability of the SEA. The follow-

ing maintenance procedures should be performed routinely after each use of

the equipment.

1. After each in-water training session, the SEA must be cleaned,

inspected, prepared for the next use or for storage.

2. As soon as possible after training, the SEA 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,

remove the protective retainer cover and 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.

3. After the system has been properly soaked, it is important to rinse the

rst 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 rst and second

stage to dislodge any water inside them. If possible, use clean low pres-

sure air to blow out of retainer cap prior to installing the rubber retainer

cover. Re-install the rubber retainer cover when the unit is completely dry.

5. Check to ensure that the SEA valve is turned to the “OFF” position,

and depress the purge button of the second stage to ensure that the sys-

tem is completely depressurized before storing or transporting.

6. Due to the possibility of re and exposure to extreme heat, the SEA

must be stored either completely full or completely empty. If the system is

exposed to re while partially lled, the cylinder wall may rupture before

the internal pressure becomes great enough to burst the safety relief disc.

For this reason, Aqua Lung recommends that the cylinder be completely

emptied and the valves kept shut to prevent the entrance of moisture

before storing the system for an indenite period.

CAUTION: If the SEA cylinder does not contain air, it is im-

portant 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 qualied

technician for inspection and service.
