Installation for ATF2 purchased pre
-
installed on a strainer
1.
Ensure the Control Toggle Switch is in the OFF (middle) position. You can push once toward MANUAL FLUSH and the switch
will automatically return to the OFF position.
2.
Remove Power Supply from packaging.
3.
Insert the 2.1mm power supply connector into the power supply jack on the bottom of the control box and run the wire through the
power cord clip on the bottom of the control box.
4.
Plug the power supply into an appropriate 120 VAC electrical receptacle.
5.
When power is connected, the Valve Position Indicator will glow red indicating that the valve is closed.
Installation for ATF2 purchased separately to install on strainer
1.
Thread the inlet of the valve onto the flush port of the strainer. The control switch is located on the outlet side of the ATF2
package and should be facing away from the strainer when properly installed. Use caution to avoid cross threading which can
damage the valve.
2.
Follow installation instructions 1 through 5 above.
Optional Power Input
If used in conjunction with the Miller
-
Leaman Pressure Differential Alarm (PDA or PDA2) package you have the option to power the
ATF2 by connecting a ML10808 Twisted Cable Power Connector from the Power Port Jack on the PDA/PDA2 control box to the
Power Supply Jack on the bottom of the ATF2 Control Box. Route the coiled cord through the Power Cord Clip.
ELECTRICAL SHOCK HAZARD. This device receives power from a 120VAC power source. The power supply must
be plugged into a circuit breaker protected receptacle that is designed for use in outdoor/wet locations. Any
required electrical work must be performed by a qualified electrician and must comply with all local, state and
national electrical codes.
GENERAL
The digital timer is set at the factory to initiate an 8 second flush sequence every 24 hours. Review the operational characteristics of
your application and program the timer with a flush duration and frequency that best suits your needs. Set the timer to allow longer
run time and improved performance of the strainer. The amount of debris stopped by the strainer can vary over time with changing
conditions, it is important to routinely check and inspect your system to ensure that too much debris does not accumulate in the
strainer which could result in equipment damage. The valve is configured as normally closed; however, in the event of an extended
power failure while the valve is fully or partially open, the actuator will be unable to power back to fully closed position. This could
result in water continuing to drain from the strainer until power is restored. It is important to inspect this equipment routinely to ensure
that the ATF2 has power and nothing is preventing the ball from fully closing. The valve position indicator on the top of the actuator
can be used as a visual aid to determine the position of the ball.
SAFETY CONSIDERATIONS / HAZARDS
OPERATION
MANUAL OPERATION AND INDICATORS
Control Toggle Switch, Lighted
The valve can be opened for a manual flush by pressing and holding the bottom of the Rocker Control Switch located
on the Control Box. The lower part of the switch will illuminate red in this position. The valve will remain open only
while the switch is being held down. Once the switch is released it will return to
“
OFF
”
position the valve will rotate
back to closed position. Automatic Flushing will not occur until the switch has been placed in
“
AUTO TIMED FLUSH
”
position and the timer has been programmed. The manual flush 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. Isolate the strainer
and utilize the pressure relief port on the lid in order to drain the strainer.
Valve Position Indicator, Lighted
A yellow indicator arrow on top of the Actuator Housing will rotate in sync with the ball valve to show the valve position.
When cutout on the yellow indicator is inline with the flush pipe, the valve is open and the indicator will glow with green
light. When the cutout on the yellow indicator is tangent to the flush pipe, the valve is closed and the indicator will
glow with red light.
PINCH POINT HAZARD. Keep fingers away from valve opening to avoid getting caught in the moving parts. The
electric motor supplies a sufficient amount of power to cause personal injury.
IMPORTANT: Any piping connected to the outlet of the valve must be plumbed to atmosphere. The flush line must
not be elevated away from the strainer and must not be piped into a pressurized line.
The Valve and Control Box are water
-
resistant but not water
-
proof. Do not install in a location where the ATF2 can
be submerged in water. Only remove the cover plate for programming. Keep cover tightly sealed at all other times.
