. Take a new 9-volt battery and snap the battery con-
nector onto both terminals.
4
. Place the connected battery into the clip provided
for it directly above the IN port (See Figure 12 on
Page 9).

. Slide the top cover back onto the ASF and push it
down to snap into place.
No reprogramming of the controller is necessary after
battery replacement or a power outage.
The ASF controller is shipped with a default value of 7
days between automatic sediment flushes. To change
the number of days (between 1 and 30) or to turn this
feature off:
1
. Press the PROGRAM button and hold it for at least
2 seconds. When the LED turns on steadily with an
amber color, quickly release the PROGRAM button.
2
. While the amber LED is on (it turns off after 10 sec-
onds of button inactivity), repeatedly press the PRO-
GRAM button until the desired number of days
shows in the display. Each press increases the
number of days by 1. When the number passes 30,
it returns to zero, indicated by “- -”, and counts up
from 1 again.
3
. Setting the number of days to “- -” (zero) turns off
the automatic flush feature.
4
. When the desired number of days shows in the dis-
play, wait 10 seconds (press no more buttons) for
the amber LED to go off. The new number of days
is programmed. This new setting will remain after
battery change or power loss.
TIME OF DAY WHEN FLUSH OCCURS
The time of day when the automatic sediment flush will
occur is the same time of day as when the most recent
of the following was done:
=
The filter was powered up (battery installed or
replaced, optional AC adaptor plugged in).
=
The number of days was set
=
A manual flush was initiated
If a different time of day is desired for automatic flush,
simply initiate a manual flush (as described on the pre-
vious page) at the desired time of day.
LOW BATTERY INDICATION
If the LED is blinking red every 8 seconds (and the 2-
digit display shows “E E“), then the battery needs to be
replaced.
BATTERY REPLACEMENT
1
. Remove the top cover from the ASF by sliding it
upward (See Figure 12 on Page 9).
2
. Locate the old battery and unsnap it from the bat-
tery connector. Dispose of (recycle) old battery
properly.
