IGS recommends a log of cleaning frequency is kept assisting in knowing how 
often this needs to be cleaned.  Each water body has different amounts of 
organics and particles in it and as such there is no set procedure.  Dirty water 
will require more frequent cleaning than cleaner water.  Common sense needs to 
be applied to the cleaning regime to ensure long term operation of the product in 
situ. 

 

Pressure Gauge Check: 

 

Checking of the pressure gauge to show a reading of 0.7 should happen every 
couple of hours if possible or daily as a minimum to ensure the unit is creating 
microbubbles at its optimum capacity.   
 
If it is noticed this tends to change check the lock nut has not worked loose.  If 
it has, readjust, and retighten the lock nut.  Also check the foot valve cage is 
clean. 
 

General Check: 

 

A general check of the overall unit should be conducted each day.  Look for 
loose connection on the suction pipe and tighten the clamps as necessary.  
Check for leakage at the delivery pipe and tighten if necessary. 
 
Check power lead connection for damage and tight connections. 
 
Check all electrical leads and connections contained within the unit are not 
showing signs of damage.  If damage is noticed contact an authorised electrician 
for repair to damaged parts. 
 
Wipe down unit occasionally in general cleaning
