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 anti-spin mounting nut to bottom of deck plate’s left side 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 cup washer and wing nut (cup washer should face up). Attach supplies to mixing valve inlets and outlet using 3/8”
compression fittings before mixing valve is attached to the deck plate. Assemble below deck mounting hardware on mixer
shank and pass mixer up through hole. From above thread above counter mounting nut (black) onto mixer until flush with
bottom of notched section. From below tighten mixer mounting hardware against bottom of sink deck. DO NOT
OVERTIGHTEN. Attach outlet of solenoid valve to shank of faucet. Connect supply from mixer to solenoid and hot and cold
inlet supplies from mixer to supply valves, all connections are 3/8” compression male. 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. The above counter mixer has a temperature limit stop (TLS). The TLS is set to allow
maximum hot and cold water flow. To change the range of hot and cold water, lift the retaining ring and TLS off the spindle
and replace it in the desired position. DO NOT REMOVE THE BEARING SLEEVE. Attach the handle so that the wing
aligns with blue and red indexes when turned. Assemble screw and index button.
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. Operate mixing valve by turning handle to the desired outlet water temperature.
