Medical Gas Supply System
Do not attempt to verify the pressure relief valve, under
any circumstances, by altering the regulator. Pressure
relief valve must be removed and tested off site by a
registered test centre for a certificate of conformity
issued.

NOTE - Isolation valves item 3, 5 and 12 are shown in
their open position, isolation valve item 14 is shown in
its closed position. This is typically the normal operating
condition for the manual valves.

Introduction.
The BeaconMedaes Medical Gas Supply System,
mainly consists of cylinder manifold system, manifold
changeover s ystem, h eader & t ailpipe a nd o ther n ecessary
components, is intended to work in conjunction with
other devices within the medical gas pipeline system
(MGPS) to assist with maintaining continuity of supply
throughout the hospital to local connection points for
eventual introduction into the human body. The device
controls the gas pressure within the specification as
required by the MGPS. In all cases other devices outside
of this scope are connected downstream of the MGPS
are required to control the final gas pressure and flow
requirements for safe supply to the patient. Therefore,
this device is not intended to control supply parameter
hazards directly to the patient, only to the MGPS.
The device including Cylinder Manifold System and
Manifold Changeover System (abbreviate as manifold
below) is principally designed for use as a primary or
secondary source of supply, or for emergency backup.
The Medical Gas Supply System supplies one of the
following medical gases to a piped distribution system,
Oxygen, Nitrous Oxide, O2/N2O 50%: 50%, Medical Air,
Surgical Air, Nitrogen & Carbon Dioxide.
See figure 1 for general arrangement and figure 2 for the
schematic diagram.
