Determine the installation of the box fixing frame based on
the toilet/urinal position. Then determine the location of
the water supply pipe and attach the control stop to the
pipe. Thereafter bore a flush pipe guide hole in the wall.
Slide a thread solder adapter on the water supply pipe if
applicable.

Do not install a handrail or any other object within the
detection zone of the sensor, as object blocking the
sensor may cause the valve to malfunction.
Additionally, to avoid the possibility of valve malfunction,
do not install the flush valve in a location where the
sensor faces a stainless wall, other highly reflective
surface or another infrared sensor.

Prior to Installing your TOTO automatic flush valve,
install the items listed bellow:
· Closet fixture/Urinal fixture
· Drain line
· Water supply line
The supply piping to these devices shall be securely
anchored to the building structure to prevent the
installed device from unnecessary movement when
operated by the user. Care shall be exercised when
installing the device to prevent marring the exposed
significant surface.
