Your Cylinder Room System

Dental CleaningSimplicity of design, solid brass components, and time-tested approved parts ensure dependability. Why pay for unnecessary chrome fittings and decorative covers which restrict servicing access? Remember, the cylinder room is in a dedicated location, out of patient's view. Over a quarter century of research and development backs the reliability of our cylinder room systems, and we believe they remain the best value available.

Category 3 Requirements

  • When the cylinder room is located within the main office area, standard installation codes are followed.
  • A "remote" cylinder room is when you must leave the primary office area to get to the cylinders. This could be the basement, an upper level, across a public hall, or outside of the main office.
  • When your cylinder room is "remote," emergency shut-off valve(s) must be used and the alarm activated down stream of the valve(s).
  • When cylinders are "remote,” a minimum of two O2 and two N2O cylinders (if used) with automatic change-over must be used.
  • The manifold is mounted on the wall of the cylinder room and unites the cylinders to the copper piping system. Our manifold is easy to check for leaks, and parts can be replaced without special tools.
  • A regulator is required for each cylinder when connected to the manifold.
  • Manifolds must meet NFPA 99 requirements:
    • Inlet one-way check valve for each cylinder
    • Pop-off valve at 50% above working pressure (usually 75 PSI for O2, 150 PSI for N2)
    • A method to activate the alarm
  • NFPA 99 codes place special restrictions on regulator hoses for cylinder room use (for nitrogen, oxygen, and nitrous oxide). All Cambiare Ltd. regulator hoses are color-coded for safety and comply with the 1000 PSI burst strength requirements. All regulator hoses have crimped DISS nut end fittings and can be used with any Cambiare Ltd. or any other manufacturer's regulator.

Testing and Documentation

We think it is worthwhile to review some testing and record keeping requirements as outlined in NFPA 99, Category 3.

Doctor: You should supervise all tests and maintain a copy of all test records!

Leak Test for all lines before manifold installation, before wall closing:
150 PSI static pressure test using nitrogen shall stand for 24 hours with less than 5 PSI drop. DO NOT USE COMPRESSORS. Record your results. After testing, use nitrogen to purge all lines. Use quick-connect hoses supplied for your analgesia unit (Do not have unit connected). Record your results.

Crossed Lines:
You must check for crossed lines. Connect O2/N2O cylinders and set pressure according to instructions. Check only one gas at a time.

Important: If using the wrench supplied with kit, IT HAS BEEN DEGREASED.

First, turn on the O2, making sure the N2O or other gases are in the OFF position and registering zero pressure. Then test every O2 station and every gas/vacuum station outlet/inlet with quick-connect hoses. Central Piping Diagram ThumbnailOnly O2 should flow, not N2O, N2, or vacuum.

Second, reverse the procedure to test N2O lines. Use same procedure for N2 and vacuum. Record your results and retain on site. Leak Test: See the Central Piping Systems Diagram to the right (items with an asterisk).
