minimum and maximum alarm limits. Acceptable alarm limits range from
0 to 2 LPM. If the sample flow reading goes beyond either the minimum
or maximum limit, an alarm is activated. The word "ALARM" appears in
the Run screen and in the Main Menu.

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, 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.
In the Main Menu, choose Alarms > Ozonator Flow.
