The value entered for the "Clean Filter Pressure" sets how far above "starting
pressure" the internal pressure of the filter must climb before the IntelliFlo
displays a "Service System Soon" alert. The "starting pressure" is the
filter pressure reading at the completion of the last backwashing. Cartridge
filters must also be "backwashed" to a clean state to establish this "starting
pressure."
When the IntelliFlo is running in Filter mode, the LCD will display the filter's
cleanliness status ("% Filter Status OK" screen) as a percent of the pressure
of a dirty filter as defined above. Once this pressure is reached, the IntelliFlo
will display the "Service System Soon" message which notifies the operator
that the filter required cleaning. When this alert is active, the IntelliFlo will
decrease speed to maintain a constant discharge pressure. The pump flow
will then necessarily decrease also until the filter is cleaned. For more
information, refer to "Clean Filter Pressure Example" on page 30.
b) To set the number of Turnovers Per Day:
buttons to find the "Turnovers Per Day" setting. Press the Select button to
select it. To change the setting, see step 4 below.
You can set up to eight turns per day (Default 1). It is recommended that one
turn per day for energy conservation and requirements be performed for most
common residential pools. Refer to sanitizer recommendation for additional
information.
c) To set the number of Cycles Per Day:
buttons to find the "Cycles Per Day" setting. Press the Select button to select
it. To change the setting, see step 4 below.
IntelliFlo uses the Cycles Per Day parameter to calculate how much time it
has to complete its filter job. You can program up to four (4) start and stop
cycles per day (Default 1). See

operate, the less power and flow will be needed for turning over the pool.
Note: Consumers in certain areas are charged lower energy rates at non-
peak hours. To take advantage of this, the IntelliFlo can be programmed to
run at any time of the day. The extremely quiet operation of the IntelliFlo
makes it feasible to operate during early morning or late at night. The
easiest and best way to optimize flow during filter cycles is by adding
or subtracting cycle time. This way, the desired flow effect, for example,
skimming action, can be achieved while maintaining the desired water
turnover rate.
