transformer) wait 15 seconds in order to allow the system 

to set the ideal sensor range. As an indication that the self 

adjusting is taking place, a LED in the sensor eye will flash

integrated in the dual power input box. (See FIG.3)

11.  Connect the water tube coming from the faucet body to the 

nut at the top of the dual power input box, by snapping it in.
