When initially starting the unit, the adsorber vessels and oxygen
receiver will be completely empty. If the feed valve is fully open when
the unit begins to run, all of the air from the feed compressor, feed
air tank, and feed piping will rush into the empty generator. This will
cause the pressure to drop below the low instrument air shutdown
setpoint. By slowly throttling the feed valve, it allows the empty
generator to be gradually filled to the point at which the feed valve can
be fully opened to its normal operating condition.
To purge oxygen at less than design concentration from the oxygen receiver,
while the oxygen generator is running, open the manual vent valve on the oxygen
receiver to vent gas. (This is the manual valve that vents low concentration oxygen
to the atmosphere to increase oxygen concentration in the oxygen receiver to the
level required for your application. Ensure that vent is sized such that the oxygen
generator is never overdrawn.)
During initial start-up, while the feed air oxygen generator piping
and hoses, oxygen lines, and oxygen receiver pressurize, apply
soapy water to all feed air piping and connections, oxygen piping or
hoses and connections, and oxygen receiver connections to check
for leaks. Repair or replace the leaking item(s).
Open the product sample valve to the oxygen analyzer assembly (if used) to monitor
the concentration of the oxygen. If an oxygen analyzer board is provided, ensure
that the pressure regulator to the oxygen analyzer board is set at 5 psig.
When the oxygen analyzer indicates the concentration of the oxygen in the oxygen
receiver that exceeds the minimum concentration specified in this instruction
manual, close the manual vent valve.
Fully open the manual outlet valves that control the flow of oxygen from the oxygen
receiver to your application, and set the pressure regulator on the oxygen receiver
outlet manifold to the pressure required for your application.
Press the ‘AUTO/MAN’ icon on the Oxygen Generator Screen so that the oxygen
generator comes in AUTO mode.
6.3 OPERATION
The oxygen generator can be operated in AUTO or MANUAL mode depending
on the requirements of your application. To use product oxygen that meets the
specifications for your model listed in the Appendix A of this instruction manual, set
the AUTO/MANUAL icon on the ‘Oxygen Generator Screen’ to AUTO to produce
oxygen only during times of the oxygen demand.
