Operation Instructions
Flush valve line must be piped to atmospheric pressure such
as an open oor drain. The ush line should not undergo
any changes in elevation and should be sloped downward in
the direction of drainage. Do not pipe the ush or drain line
into a pressurized line.
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 dierent
parameters that aect the required frequency between
ushes and the duration of the ush, the end-user must
choose the controller’s settings (refer to your speci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 ush side of the
control switch (lower switch light should come on then
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 18).
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 (24) hours. (See Figure 18).
6. Set the control switch to auto ush. The red o light
on the timer will come on and the upper light on the
switch will come on and stay on. During the ush cycle
the on light on the timer and the lower switch light will
come on.
Control Switch
Control switch ushing is initiated by pressing and holding
down the manual control switch located on the front of the
controller (See Figure 19). The manual 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 ush
control switch is released, the valve will automatically close.
SAFETY FIRST! - Keep ngers away from valve opening
to avoid getting caught in the moving parts. The electric
motor supplied a su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 ush settings. Keep the cover tightly sealed on
the unit during normal operation.
Pressure Dierential Alarm Package Option
The pressure dierential alarm (PDA) option continually
monitors and displays the strainer’s inlet and outlet
dierential pressure. When the strainer element (conical
strainer basket) becomes signicantly clogged, the pressure
dierential switch-gauge will trigger an audible siren and
a visual ashing alarm light. These alarms are intended to
alert maintenance personnel that the strainer element
must be removed and cleaned (See Strainer Element
Cleaning on page 40).

Operation Instructions
Remove the power supply and insert the connector end into
the socket on the bottom of the PDA housing (See Figure
21 above) and plug the transformer into the power source.
Standard systems are supplied with a 120V power supply to
the primary of the transformer, with an output secondary of
12 VDC. The pressure dierential switch-gauge is factory set
to 7-8 psi. The CS strainer operates at a pressure dierential
slightly less than 1 psi during maximum ow when the
strainer screen is clean. By the time the dierential pressure
reaches 7-8 psi, the strainer element will be signicantly
clogged and require immediate removal and cleaning. To
adjust the pressure dierential switch-gauge setting, insert
a 1/16” allen wrench and rotate the dierential set point
contact to the desired location (See Figure 21). Note: It is
not recommended to set the dierential switch-gauge
higher than 10 psi. Disabling the alarm or increasing the
alarm set point could result in damage to the strainer
element and allow debris to pass into the system.
