POWER UP
When the controller is powered up (by installing the
battery or plugging in the optional AC adaptor), the dis-
play will briefly show the software version (example
“1.0”), then the number of days until the next automatic
sediment flush.
MANUALLY START A SEDIMENT FLUSH
After all installation steps have been completed, initiate
a manual sediment flush as follows:
1
. Press the CLEAN NOW button and hold it for at
least 2 seconds. When the 2-digit display changes
to show moving dashes (See Figure 20), release the
CLEAN NOW button.
2
. Check drain hose to ensure a secure connection.
3
. The sediment flush sequence takes about 30 sec-
onds to complete. The flow of water to the drain will
start and stop several times.
4
. Once the sediment flush has been completed, the 2-
digit display will change to show the number of days
until the next automatic flush (or if the automatic
flush feature has been turned off it will show “- -”).
The ASF can be manually activated to flush sediment
at any time, regardless of whether or not it is set to
flush automatically.
NORMAL OPERATION
During normal operation, the LED will momentarily
blink green every 8 seconds and the 2-digit display
(LCD) will show the number of days remaining until the
next automatic sediment flush. Momentarily pressing
the PROGRAM button shows the setting for the num-
ber of days between flushes.
LCD BACKLIGHT
The 2-digit display has a backlight that goes on when-
ever a button is pressed. It goes off again after 10
seconds if no more buttons have been pressed (to
conserve battery life). Momentarily press either the
PROGRAM or CLEAN NOW button to turn on the
backlight.
