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

Installation Procedure

WARNING: To minimize the risk of electrical shock and fire hazard, be sure to turn off and lock out breaker for power line before starting the installation.

Step 1

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.

Note

Attach the control stop before installing the box fixing frame.

surface or another infrared sensor.

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.

For TET2ANS-32

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.
