INSTALLATION
Remove cover from faucet body. Disconnect sensor module wires and remove module from faucet. Remove battery cover 
from module and install new batteries, taking care to ensure correct polarity. Reassemble in reverse order as above. Make sure 
module wire is plugged in and clipped into place on top of the module. Wires should be on the inside of cover screw bosses of 
chassis to prevent pinching. Reattach cover to faucet with screws and wrench provided. Install vandal resistant aerator with 
wrench provided. Ensure gasket is properly seated on bottom of faucet chassis. Insert faucet shank and wire through hole on 
the center of deck plate. With notch on deck plate center hole facing forward, fasten faucet to deck plate using four (4) screws 
provided. Tighten two anti-spin mounting nuts to bottom of deck plate and slip rubber gasket onto bottom of deck plate. 
Carefully feed wire from faucet through deck hole, mounting faucet on fixture. Attach notched wire guard (notched end up) 
washer and lock nut onto faucet shank and secure faucet to fixture. CAUTION: Sensor module wire must be inside channel of 
rubber wire guard to keep wire from being pinched or cut when tightening washer and lock nut. Further secure faucet to fixture 
with the two (2) cup washers and wing nuts (cup washers should face up). Attach outlet of solenoid valve to shank of faucet. 
Attach supply to solenoid valve using 3/8” compression fittings. DRY CONNECTIONS ONLY. Connect wire from faucet to 
solenoid valve. With drain installed, turn on water and activate the faucet, checking for proper operation and all connections 
for leaks. 
OPERATION
Speakman SENSORFLO faucets are thoughtfully designed for all in mind. Require no handles to turn, lift or push, water flows 
only when hands are in the lavatory basin. Built in vandal resistant circuitry shuts off the water after continuous flow of 
approximately 60 seconds. This feature prevents flooding; water is easily turned on again by placing one’s hands under the 
lavatory spout. 
MAINTENANCE (CARE & CLEANING)
Your SENSORFLO faucet is designed and engineered in accordance with the highest quality and performance standards. With 
proper care it will provide years of trouble free service. Periodically the faucet will require some minor maintenance to keep it 
performing at peak performance. The sensor module has a built-in low battery indicator light located in the center of the 
rectangle infrared lens. This red light will come on when the faucet has approximately 30,000 on/off cycles remaining or 10% 
of battery life. To replace the batteries follow the first portion of the installation instructions above. Periodically check the
