AS-D+—AS-P Series Instruction Manual 39
AirSep Corporation
During initial start-up or start-up after a long period, the oxygen
concentration can be lower than the low concentration alarm and/
or shutdown setpoint and a ‘low concentration’ alarm may exist.
However, the oxygen generator ignores the oxygen concentration
shutdown setpoint for the rst 60 minutes after start-up. If the
oxygen concentration after 60 minutes of operation is still below the
low concentration shutdown setpoint, the oxygen generator shuts
down.
The low concentration shut-off valve (if installed on the oxygen receiver) will only
open when the oxygen concentration is above the shutdown set point to allow
the product oxygen to ow to your application. This valve assembly comes as an
optional feature with the oxygen generator.
6. Set the AUTO/MAN icon on the ‘Oxygen Generator Screen’ to manual
mode.
7. Press the ‘START’ icon on the ‘Main System Control Screen’.
8. Slowly open the manual feed #2 valve (V-2) until it is open completely.
9. Close the manual product valve (V-3) (refer to Figure 4.2 for location of
valve). The manual product valve on these units has been configured
to enable a predetermined amount of flow through the valve when
closed. This allows the product pressure to build up even when the
valve is closed.
10. Press the manual drain button and make sure the exhaust from the
filter drain does not contain water or oil. If the exhaust contains water
or oil, press and hold the manual drain button on the control panel until
the exhaust no longer contains liquid.
While venting oxygen, do not allow smoking or open ame. Do
not allow venting oxygen to come in contact with clothing or
hydrocarbon-based materials.
11. Allow the oxygen generator to operate until the oxygen receiver
pressure on the ‘Output Parameters’ screen (Figure 4.6) registers
approximately 276-310 kPa (40-45 psig) and then fully open the
manual product valve (V-3).
12. To purge oxygen at less than design concentration from the oxygen
receiver, open the manual vent valve on the oxygen receiver to vent
gas while the oxygen generator is running in manual mode. Manual
valve should be open slightly so that pressure will still build up in the
oxygen receiver tank.
