Have the orange valve fully open: 

 

If this valve is included in your unit, ensure 
it is fully open during operation.  This 
ensures the valve does not throttle the water 
flow in any way.  The photo at left shows 
the valve partially closed – make sure this 
remains fully open during operation. 

 

 

Connection of electrical power lead: 

 

The orange power lead shown at left at the bottom 
of the electrical board needs to be connected by an 
authorised electrician and has enough length to 
allow you to connect to a three-phase electricity 
supply. 
 
If additional length is required if the unit is relocated 
this can be achieved using a three-phase extension, 
making sure that any connection is kept out of water 
that may be around the unit. 
Connection is simple and if in doubt seek the advice 
of an electrician. 
 

Once the above connections are made with the unit in a stable upright position 
you will be ready to turn the unit on and commence the production of 
microbubbles, which will in turn break down to nanobubbles.   Double check all 
connections at this point. 
 
Lower the foot valve with the two hoses connected into the water source.   
Make sure that the cage is suspended in such a way it can operate without 
obstruction or is sitting comfortably on the base of the water source if a tank.
