AS-A—AS-P Series Instruction Manual 7-1
7.0 Maintenance
The most important maintenance you can perform on the oxygen generator is to
make sure the automatic drain valve for the filters functions properly. Routinely
monitor the operation of this drain valve to ensure the long life of the oxygen
generator. Follow the procedures described in this section of the instruction
manual for daily, semi-annual, and annual maintenance. It should be noted that
few procedural steps in the sub-sections might apply to a specific model.
Use the following chart as a guide to perform maintenance on a regular schedule:
Time Period Action
Daily Make sure automatic drain functions properly.
Monthly Inspect filters and bowls. Clean bowls or replace filters as necessary.
Six Months Replace particulate filter element.
Annually Replace coalescing filter element.
Check performance of automatic valves and actuators.
Clean and lubricate feed air regulator.
Table 7-1 Maintenance Chart
7.1 Daily Monitoring
1) Make sure the condensate outlet and tubing for the drain valve is not obstructed.
Condensate should discharge from this outlet or tubing for approximately
three to five seconds every 10 minutes when the ON/OFF switch on the control
panel is set to ON and the green indicator light on the switch illuminates.
2) Press the MANUAL DRAIN button on the control panel and observe the
discharge. The discharge should flow freely and be clear of oil and water
within five seconds.
7.2 Monthly Monitoring
Monthly monitoring requires inspection of the filters and testing the performance of
the automatic drain valve. To perform this procedure, remove the front cover of the
enclosure, depressurize the unit and remove the filter bowls as described in the
following procedures. (See Section 7.3, Removing the Front Cover of the
Enclosure, Section 7.4, Depressurizing the Filters, and Section 7.5, Changing Filter
Elements.) When the filter bowls have been removed and cleaned, perform the
following steps:
1) Inspect the filter element(s). Replace any element(s) that appear damaged or
excessively dirty.
2) Reconnect the drain tubing to the bottom of the bowls.
3) Add approximately two ounces of water to the filter bowls.
