manual flushing
nOte: manual flushing only works when unit is in
flush Interval mode (fi).
While the unit is in Flush Interval Mode (decimal point
flashing), hold the start button down for 6-7
seconds until the LED displays FL (Figure 11).
Continue holding the button down to keep the drain
open. Drain will remain open for as long as start button
is depressed. (FL will flash on LED.) Releasing the but-
ton closes the drain and puts the unit back into startup
mode. After ten seconds, if the start button is not pressed
the unit automatically returns to the Flush Interval Mode
(Fi).
