Product Description
The medical gas manifold shall be Ohio Medical Healthcair® series. The manifold shall comply with the latest edition of NFPA-99.
The manifold shall provide an uninterrupted supply of gas to the pipeline at a constant pressure. The manifold shall permit automatic
switchover for the “in use” (primary) bank of cylinders to the “reserve” (secondary) bank of cylinders.
The manifold shall have a NEMA 4x enclosure allowing the manifold to be mounted outdoors in a semi-protected environment (0o –
140oF). The manifold shall be equipped with an internal power supply module, header bars/cylinder connections, master shut off valves and optional external heaters for Nitrous Oxide (N2O) and Carbon Dioxide (CO2) service.
The pressure control cabinet shall contain dual pressure regulators and switches that assure an uninterrupted, regulated flow of gas
to the pipeline. The cabinet shall have a digital pressure display and analog three pressure gauges, one for each supply side and one
for the pipeline delivery pressure. A group of indicator lights shall be used to indicate the status of the left and right cylinder banks. “In
Service “ is indicated by the green light, and the “Reserve” cylinder bank is indicated by the yellow “Ready to Use” light. A red “ Replace
Cylinder” light indicates a depleted cylinder bank. The manifold shall be equipped with a left or right bank inlet priority switch. An
external switch over setting module shall be provided.
The control cabinet shall be equipped a leak detection alert, in the event the reserve cylinder bank decreases by 25% from the initial
standby pressure. When this occurs, the standby status light and the empty status light will blink indicating that a leak has been detected.
The unit shall include a self diagnostic testing feature to check the internal inlet and delivery pressure transducer sensors. During
this test if a fault is found the digital display will read “ERROR” Right, Left, or Delivery depending on where the fault was generated.
Dry contacts are provided in the internal alarm terminal strip for connection to a remote alarm to signal when the reserve bank (secondary) is in use. No manual resetting is required when the bank has been replaced with new cylinders and re-pressurized, the red light goes off and the yellow “Ready to Use” light comes on and the replaced bank is now the reserve bank.
