Ozonator Flow The Ozonator Flow screen (read only) is used to display the ozonator flow
readings. If the ozonator flow reading is 0.050 LPM (50 cc) or below, an
alarm is activated, and an alarm condition screen appears as “LOW”. If the
ozonator flow is above 0.050 LPM, the no alarm condition screen is
displayed, indicating that the flow is acceptable. Inadequate ozonator flow
will cause the ozonator to overheat, resulting in permanent damage to the
ozonator.
