Specification
Installation Precautions
1. Prior to Installation
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.
2. Important
All plumbing is to be installed in accordance with
applicable codes and regulations.
Water supply lines must be sized to provide an
adequate volume of water for each fixture.
Flush all waterlines prior to operation.
The minimum pressure required to the valve is
determined by the type of fixture selected. Consult
fixture manufacturer for pressure requirement.
Do not use toothed tools to install or service the valve.
3. Main dimensions of the piping

4. Use care not to damage the surface of the infrared
sensor.
5. For Toilet Flush Valve
The toilet sensor valve may not function if toilet seat
and/or lid cover are left upright as it may block the
sensor.
6. For Urinal Flush Valve
The automatic flush valve is designed to be used with a
washout urinal for optimum performance. However, a
siphon jet urinal may also be substitutional. Blowout
urinals are not recommended.
7. The detection range of the infrared sensor is shown in
the figure below.
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.
Refer to local codes for special requirements.
Note
Detection zone
The detection zone is self-adjusting and is equipped with a
3-second flush delay after removal from the detection zone.
(No flush delay for Urinal flush valve)
The detection zone may differ according to color of user’s
clothes.
When a user wears black clothes, the detection zone may
become smaller and the valve may not flush.

sensor in front of a
