MANUFACTURER’S RECOMMENDED MAINTENANCE CHECKS
1. Annually
- Perform interior cylinder inspection, clean cylinder as required.
a. Inspect exterior of cylinder valves.
i. Clean both cylinder valve threads.
ii. Lubricate both cylinder valve threads.
iii. Inspect mechanical operation of the cylinder valves.
2. Annually (pre-mission)
- Perform a complete leak check on the Atlantis.
a. Attach two full cylinders to the jacket.
b. Slowly open one cylinder and fully inflate the Atlantis until the Over Pressure
Relief Valve (OPRV) releases pressure. Close the cylinder.
c. Verify the Over Pressure Relief Valve (OPRV) re-seats and does not leak.
d. Test the Rapid Exhaust Valve (REV) by pulling on the oral inflator until
air releases.
e. Refill the jacket and remove the cylinders from the jacket.
f. Verify no leakage from the cylinder connectors, caps or oral inflator.
g. Allow the jacket to sit fully inflated for one hour.
h. After one hour, inspect the jacket for fullness. If the pressure has gone down
significantly, refill the jacket and check the Atlantis for leakage by submerging
the BC fully in water and re-test. Repeat steps a–h, until no leakage is present
or have the jacket repaired by a trained technician prior to use.
3. Annually (or as required)
- Replace the external o-ring on the cylinder valve
connectors.
a. Carefully remove the o-ring on the cylinder valve connectors.
b. Replace the o-ring with a new lubricated o-ring.
4. Annually (pre-mission/pre-use)
– Inspect the strap assembly.
a. Inspect all straps for damage or chafing.
b. Inspect all hardware connectors for cracks or breakage.
c. Inspect de-rigging loops for damage (mission specific).
5. every 5 years
– Rebuild air cylinder supply valves.
6. every 5 years –
Hydrostatically test cylinders (if desired, not DOT required).
7. As required
- Paint HP air cylinders.
8. As required
- Prepare the Atlantis for extended storage in excess of 30 days
a. Perform #2 annual check- perform complete leak check on jacket.
b. Remove cylinder valve connectors, oral inflator and caps.
c. Store the Atlantis deflated in a clean, dry area away from extreme
temperatures: NGT 120ºF/49ºC and NLT 0ºF/-18ºC.
d. Store cylinders fully charged to 3000 psi (206 bar) or with less than 20 psi (1.4 bar).
9. As required –
Check Atlantis for operational integrity.
note
:
.25 in (7mm) is all the pull required. excess force will damage the airway
assembly. Release the oral inflator and verify no leakage from the REV.
