MAINTENANCE
GENERAL
The tests and inspections specified below apply only to the Amico manifold and not to the medical
gas pipeline system as a whole. They are intended to help ensure the proper operation of the manifold
and not to be interpreted as repair instructions. Fault finding and repair procedures are given in the
Trouble Shooting section of this manual.
AMICO CONTROL EQUIPMENT
Control equipment should be inspected and tested according to the following schedule:
1.
Pressure Regulator:
A.
Observe and record line pressure periodically.
B.
Test for external leaks at least semiannually.
C.
Switch line regulators monthly (if applicable).
2.
Pressure Relief Valves:
A.
Determine the pressure at which relief occurs at least annually and compare with the
requirements of “
Clause 4-3.1.8.5. of NFPA 99
”.
3.
High Pressure Inlet Valves (Manifold Hand Valves):
A.
Inspect semiannually and test for external leakage and tightness of shut-off.
CYLINDER EXTENSION BARS
The following components shall be inspected semiannually as indicated:
1.
Test check valves of pigtail assemblies for proper closure.
2.
Inspect pigtail assemblies for apparent damage and thread damage to cylinder connec-
tions, replacing all damaged pigtails immediately.
NOTE: Replace ALL pigtails after 5 years service.
The cylinders and the operating pressure regulators of a nitrous oxide or a carbon dioxide
supply system shall be observed daily during peak demand periods to determine whether
they show frosting or condensation on the surface.
Where this is evident, the system shall be further inspected for evidence of leaks. Should
excessive condensation or frosting occur, it may be necessary to upgrade to an Amico
Microprocessor Digital Manifold with a built in heater kit.
PERIODIC STANDING PRESSURE TEST
At intervals of not more than 5 years, a 1-hour standing pressure test shall be made on each medical
gas system to check for leakage.
