Centrox Instruction Manual

1. Observe that the ON/OFF switch on the PSA module is in the off
position.
2. Insert the compressor module electrical plug to the electrical inlet at the
bottom of the PSA module. Refer to Figure5.1.
3. Connect the PSA module power cord to a properly grounded electrical
outlet that cannot be accidentally turned off. Do not use extension
cords.
If a power light is off, first check the electrical connection and then
the oxygen concentrator circuitry. If this condition still exists, refer
to the Troubleshooting section.
5. Set the AUTO/MANUAL switch on the PSA module to the MANUAL
position.
6. Ensure that oxygen isolation ball valve is open (See Figure 5.1).
If the unit is equipped with an oxygen monitor, the oxygen monitor
light on the control panel remains on until the oxygen purity
reaches 85% ±3%. The oxygen monitor alarms intermittently after
30 minutes if the Centrox does not reach proper oxygen purity.
During start-up, this alarm is silenced for 30 minutes.
Air exhausts for 3-5 seconds from the feed air dump valve (See
Figure A.1). This is normal. It removes any pressure that builds up
inside the compressor to ensure easy start-up.
8. Close the primary and the secondary oxygen ball valves (See Figure
5.1).
9. Remove the hose that connects the center fitting of the primary/
secondary ball valve assembly to your distribution system. This will
allow the air in the tank to be vented to the atmosphere.
10. Put the supply valve in the closed position (See Figure 6.1).
There is a small hole drilled in the supply ball valve to allow a
controlled amount of gas to flow into the tank receiver when the
valve is in the closed position.
11. Set both the ON/OFF switches on the compressor module in the ‘ON’
position.
