RECHARGE CYCLE TIME ADJUSTMENTS
The default setting for backwash and aspirate times
of the recharge cycle are factory set for maximum
performance of the filter. Use the following proce-
dures to check for correct cycle times, or to change, if
desired. It is recommended that only trained techni-
cians should change the time settings.
NOTE: Fill and brine times are adjustable, but set at
the factory to zero. It is recommended to
leave these settings at zero, unless the filter is
used in a custom application by the installer.

until the display shows “000 - -“, then press the
SELECT button again to display the backwash time
adjust screen (See Figure 23).
2. The default setting is 75 minutes. Use the
á

or
â
DOWN buttons to adjust aspirate time from 0
to 99 minutes.
3. When the desired aspirate time is displayed, press

AUXILIARY OUTPUT CONTROL
The electronic controller’s auxiliary output may be
used to operate various types of external equipment,
such as a chlorine generator or chemical feeder. It
provides a 28V DC, up to 300 mA, current from termi-
nal J4 on the electronic control board (see Schematic
on Page 16). The table below explains the choices
available for when the auxiliary output will be on dur-
ing various portions of the recharge cycle:

If setting to CF (Chemical Feeder), there will be
two additional settings to make for operating the
chemical feeder in Steps 4 and 5, on the next
