BATTERY REPLACEMENT PROCEDURE

Sloan OPTIMA Plus

EBF-85 and EBF-187 Battery Powered, Sensor
Activated Lavatory faucet models are furnished with four (4) Duracell C-
size Alkaline batteries that provide up to 2 years of operation (at 8000
cycles per month). When the batteries are low and need to be replaced, the
EBF-85 and EBF-187 will signal you. When 256 cycles remain in the unit,
the faucet will BEEP each time it is activated. At this point we recommend
battery replacement. Sloan Valve recommends the use of Duracell MN-
1400 C-size batteries.
To Replace Batteries:
Note:
Water supply to the faucet does not need to be turned off when
replacing batteries.
Loosen security set screw on the Coupling Ring with a 0.05” hex wrench.
Unscrew Battery Compartment Coupling Ring. Remove Battery
Compartment. To ensure proper operation, remove old batteries and insert
four (4) new C-size Alkaline batteries. Check that the orientation of each
battery matches the positive (+) and negative (-) symbols shown at the
bottom of the Battery Compartment. Reattach the Battery Compartment to
the Valve Module by aligning the arrow on the Battery Compartment with
the arrow on the solid tab of the Solenoid Valve Module. Secure by
tightening Battery Compartment Coupling Ring. To deter unauthorized
removal of batteries, use a 0.05” hex wrench to tighten the security set
screw on the Coupling Ring.
Upon installation of the batteries, the EBF-85 and EBF-187 faucet will begin
a new self-calibration procedure (see START UP MODE).
