MAINTENANCE
Every 12 months, we recommend purging the membrane sticks . To do this, force all
air to one ProAir™ 4 diffuser for 10 seconds by closing all valves on the compressor
manifold except one . Repeat for all ProAir™ 4 diffusers . For aeration systems
containing only one diffuser, pull the pressure relief valve on the compressor and
let go . Repeat this process 6 to 8 times .
TROUBLESHOOTING
If you have loss of airflow to one or more diffusers:
• Check to ensure airflow valves on compressor manifolds
are adjusted correctly .
If large boiling bubbles are present on the water’s surface:
• Check membrane sticks for tears .
• Check for loose connections on diffuser manifold .
