Note: The Automatic Timer Flush Package needs to be
programmed when it is received by the end-user. The
programming is simple and takes only a few moments.
However, because every application has diff erent parameters
that aff ect the required frequency between fl ushes and the
duration of the fl ush, the end-user must choose the controller’s
settings (refer to your specifi c strainer manual).
To Program the ATF Controller
1. Plug the transformer into a 120-VAC outlet.
2. Insert the 12-VDC plug coming from the transformer into the
jack on the underside of the ATF box.
3. Test for power by pressing the manual fl ush side of the
control switch (lower switch light should come on the valve
will start to open).
4. Adjust the “ON TIME” (Valve Open) by turning the inner
timer ring with the GREEN POINTER clockwise to increase
duration. The ON TIME RANGE is factory set at eight
seconds. (See Figure 1).
5. Adjust the “OFF TIME” (Valve Close) by turning the outer
ring with the RED POINTER clockwise to increase duration.
The OFF TIME RANGE is factory set at twenty-four hours.
(See Figure 2).
6. Set the control switch to auto fl ush. The red off light on the
timer will come on and the upper light on the switch will
come on and stay on. During the fl ush cycle the on light on
the timer and the lower switch light will come on.
Control Switch
Control switch fl ushing is initiated by pressing and holding down
the manual control switch located on the front of the controller
(See Figure 4). The manual fl ush control switch can also be
used to conveniently drain the water out of the strainer before
removing the conical
screen element from the strainer housing. A
yellow indicator arrow on top of the ATF valve will rotate in sync
with the ball valve to show the valve position (open or closed).
When the manual fl ush control switch is released, the valve will
automatically close.
SAFETY FIRST! - Keep fi ngers away from valve opening to
avoid getting caught in the moving parts. The electric motor
supplied a suffi
cient amount of power to cause personal injury.
Take precaution when handling.
Water Resistance
The Valve and Controller are water-resistant, but not water-
proof. Do not install below ground level where the component
can be submerged in water. Only remove the cover plate
from the Valve Controller when setting or changing the fl ush
settings. Keep the cover tightly sealed on the unit during normal
operation.
