The Sloan optima plus EBF-625 and EBF-655 battery powered, sensor activated
lavatory faucets are furnished with four (4) “C” cell alkaline batteries that provide up to
two (2) years of operation (8000 cycles per month). a flashing lED signal indicates that
battery power will be depleted within one (1) month. replace batteries with four (4)
new “C” cell alkaline batteries.
remove the Cover of the Control module by unscrewing the four (4) cover screws lo-
cated at the center of each side.
remove the battery compartment from the control module by gently pulling straight out
with a firm grip. Spread the ends of the battery reainer and remove it from the battery
compartment. remove the old batteries and insert four(4) fresh “C” cell alkaline
batteries into the battery compartment. Spread the ends of the battery retainer and
slide it over the battery compartment until locked into place.
NoTE: Battery retainer muST be installed as shown. if installed upside-down, it will
not install into the Control module. reinsert the Battery Compartment into the Control
module as shown.
place cover over the Control module and use the four (4) screws provided to attach it.
Cover can be installed in only one orientation.
imporTaNT: install all four (4) cover screws for proper installation.
ClEaNiNg SCrEEN FilTEr
Before cleaning the screen filter, turn off water supply at the supply stop(s).
activate the faucet to relieve any pressure in the system. unscrew the filter plug
and remove it from the solenoid valve housing. Carefully pull the screen filter
with attached rubber seals out from the solenoid valve housing.
Clean the screen filter using fresh tap water only. if necessary, use a small
brush to clean. use caution while cleaning to prevent damage to the solenoid
screen filter. if any filter components are damaged, order Filter replacement Kit
EBF-1004-a.
Carefully replace the screen filter into the groove of the solenoid valve housing.
Examine the filter plug o-ring for wear or damage; replace if necessary. if nec-
essary, lubricate the filter plug o-ring with water to keep it in place in the groove
of the filter plug. Screw the filter plug into the solenoid valve housing.
Turn on the water supply at the supply stop(s). activate the faucet to purge any
air from the system lines. Check for leaks and repair as necessary.
OPERATION
1.
a continuous
invisible beam of
infrared light is
emitted from the
sensor located on the
throat of the lavatory
faucet.
2.
as the user’s hands
enter the beam’s
effective range (be-
neath the spray
head), the beam is
reflected back into
the sensor receiver
and activates the so-
lenoid valve. Tempered water flows from the
faucet into the sink until the hands are
removed from the beam or until the faucet
reaches an automatic time out limit setting.
3.
when hands are
moved away from
the sensor, the loss
of reflected light
initiates an electrical
signal that
deactivates the
solenoid valve, shut-
ting off the water flow. The circuit then auto-
matically resets and is ready for the next user.
MAINTENANCE
CarE aND ClEaNiNg
Do NoT uSE abrasive or chemical cleaners (including chlorine bleach) to clean faucets that may dull the luster and attack the chrome or special decorative finishes.
use oNly soap and water, then wipe dry with clean cloth or towel. protect the faucet from any splattering of cleaner when cleaning bathoom tile. acids and
cleaning fluids will discolor or remove chrome plating.

TROUBLESHOOTING GUIDE
1. Faucet does not stop delivering water or continues to drip after user
is no longer detected (automatic shut-off fails even when batteries
are removed.
Solenoid valve has been connected backward.
Disassemble solenoid valve compression fittings at both the inlet
and outlet positions. The water should flow from inlet through the
solenoid valve ot the outlet according to the direction of the arrow
shown on the side of the solenoid valve. reconnect the
compression fittings in the correct orientation.
Solenoid valve is dirty.
Backflush by reversing water flow (opposite to the direction shown
by the arrow on the side of the solenoid valve) through the solenoid
valve. reconnect the compression fittings in the correct orientation.
activate faucet.
Solenoid valve module is defective.
replace EBF-1011-a Solenoid Valve module.
