MAIntenAnCe:

Once every 12 months we recommend purging the membrane sticks. To do 
this, force all air to one ProAir™ 4 diffuser for 10 seconds. Repeat for all ProAir™ 
4 diffusers within an aeration system. For aeration systems containing only one 
ProAir™ 4 diffuser, pull the pressure relief valve and let go. Repeat 6 – 8 times.
