Should it stop operating check the water supply is still OK and start again. If the 
pump still does not work the electrical supply will need to be checked.  If the 
electrical supply is found OK, then contact IGS for further assistance. 
 

Actuators: 

 

These actuators are critical for the 
operation of the system.  The actuator on 
the right has a tap below it (behind the 
wiring), which brings air in from the side 
(blue open plug) and has a set screw 
adjustment on the top. 
 
There is no need to adjust the left-hand 
actuator. Take care as this actuator does 
get hot.  You will not need to adjust the 
right-hand actuator, only the air valve. 
 

Cavitation cylinder: 

 

The cavitation cylinder is a critical operational 
component of the product for the creation of 
microbubbles.  It is found at the rear of the unit on 
the left-hand side, under the electrical enclosure. 
 
On the top of this cylinder is a pressure gauge 
which will need to be checked in operation, with 
adjustments made on the air intake actuator. 
 
No other operator input is required for this cylinder.
