AS-Q—AS-Z Series Instruction Manual 47
AirSep Corporation
7.4 ANNUAL MAINTENANCE
Perform the annual maintenance procedure only with the oxygen generator shut
down.
Do not attempt to remove the filter bowls until the filter assembly
fully depressurizes.
7.4.1. MAINTENANCE OF AUTOMATIC VALVES
If possible, the functioning of the valves should be checked daily.
1. Check all moving parts on the oxygen generator (automatic valves
and pneumatic actuators) for any indication of wear. Replace all worn
parts.
2. Make sure all automatic valves operate properly. Make sure all
connections remain tight and that each valve opens and closes
properly.
3. If a valve operates slowly (two seconds or more), repair or rebuild the
solenoid valve or valve actuator. Refer to the valve manufacturer’s
literature in Appendix D of this instruction manual for more
information.
4. Check all automatic valves and pneumatic actuators for leaks.
Use soapy water to check leaks at the valve stems. If the valves or
actuators leak, tighten or replace the packing.
Do not over-tighten packing bolts on air operated valves.
7.4.2. COALESCING FILTER REPLACEMENT
The coalescing filter causes oil “fog” particles and water vapor that pass through
the particulate filter to collide (coalesce) and form larger droplets, which fall to
the bottom of the filter bowl. Replace the coalescing filter element(s) annually.
The expected life of the coalescing filter is approximately one year
with proper maintenance of the particulate filter. The coalescing
filter has a rating of 0.01 microns.
1. Follow all steps in Section 6.6 — Extended Shutdown.
