• Install a check valve 10 inches after the ozone outlet tube fitting (the venturi has an
internal check valve).
• This can be done by cutting the tube ten inches after ozone out fitting.
• Next, connect both ends of the cut tubes to the check valve.
• Please direct the arrow on the check valve toward the venturi injector.
• First, start up the swimming pool water recirculation pump.
• Make sure there is a vacuum at the venturi injector via a gauge and test it by putting
your finger on the venturi injector opening.
• A small suction should be felt at this injector opening. This is what is needed to get the
ozone production out of the SP unit and injected into the pool’s piping system.
• Check that the flow meter indicates that the air flow is at least 2 LPM.
• Now connect the PTFE tube from the venturi to the ozonator.
• Turn on the power on the external panel of the ozone generator.
• The ozone indicator light should illuminate and the unit’s fan should turn on.
• Increase power to the cells by turning the ozone control knob clockwise.
• Please refer to the charts above for the approximate ozone concertation for you size of
pool.
