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.

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.
