4 SHUTDOWN
WARNING
Before disconnecting or disassembling the ejector, shutdown the system
as described below. Failure to do so may result in serious injury or death.
1. Close the gas supply valve at the pressure source(s) to shut off the gas flow. This is normally the gas
cylinder and/or container valve(s) supplying the gas dispensing (regulator) system. The rate valve on the
dispensing system meter panel(s) is/are not to be used to shut off the gas flow. The float in the gas
flowmeter(s) should drop to the bottom of the flow meter indicating zero (no gas feed)
2. Continue the flow of water through the ejector for a few minutes to remove all gas remaining in the feeder,
pressure piping and vacuum tubing. While the ejector continues to operate remove the vacuum tubing from
the gas inlet of the ejector to allow air to enter the unit further diluting the residual gas. Stop the ejector water
flow and relieve all residual water pressure. Close any water supply and chemical solution valves to isolate
the ejector.
