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 specic strainer
type 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.

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
