6.0 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 a few
procedural steps in the sub-sections may 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.

6.1 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 oxygen
generator is running.
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.
6.2 MONTHLY MONITORING
Monthly monitoring requires inspection of the filters and testing the performance
of the automatic drain valve. To perform this procedure, depressurize the unit and
remove the filter bowls as described in the following procedures. (See Section 6.3,
Depressurizing the Filters, and Section 6.4, 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.
4. Re-install the filter bowls, making sure the bowls lock firmly into place.
