Use of pressure gauge on top of cylinder:
This pressure gauge needs to show an
operating pressure of 0.7 for the unit
to be creating microbubbles at the
highest efficiency.
In start-up operation the pressure will
read anywhere either side of 0.7. An
operator needs to adjust the air flow
to achieve a 0.7 reading on this
gauge. No other action is required
for this cylinder or gauge except to
check the pressure now and then.
Note:
to adjust the pressure you need to adjust the air intake actuator.
Adjusting the air intake actuator:
The air intake actuator is the right-hand side
actuator which has the blue open plug injected
in the right-hand side of the pipe above the
actuator.
To adjust the pressure in the cylinder, open
the red handle tap that can be seen behind the
wiring at the front of the actuator. Open this
tap fully by pushing it toward the bottom of
the unit until it is in a vertical position.
Next turn the set screw at the top of the pipe
shown here and adjust by raising or lowering
the screw until the pressure on the gauge is
showing 0.7.
