OPTIMA® Sensor Activated Flushometers  
OPTIMA® Components:  
The Sloan OPTIMA automatic electronic Flushometer relies on an infrared sensor  
to detect a user and activate a flushing cycle. No physical contact with the  
Flushometer surface is necessary, assuring sanitary protection. OPTIMA  
Flushometers are ADA-compliant devices and are available in both Royal® and  
Regal® Flushometer models. These hardwire Flushometers require the use of 24  
VAC Stepdown Transformers.

LIMITED WARRANTY  
Sloan Valve Company warrants its Flushometer Products to be made of first  
class materials, free from defects of material or workmanship under normal  
use and to perform the service for which they are intended in a thoroughly  
reliable and efficient manner when properly installed and serviced, for a period  
of three years (one year for special finishes) from date of purchase. During this  
period, Sloan Valve Company will, at its option, repair or replace any part or  
parts which prove to be thus defective if returned to Sloan Valve Company, at  
customer’s cost, and this shall be the sole remedy available under this  
warranty. No claims will be allowed for labor, transportation or other incidental  
costs. This warranty extends only to persons or organizations who purchase  
Sloan Valve Company’s products directly from Sloan Valve Company for  
purpose of resale.  
The Flushometer is triggered by means of a self-adaptive infrared sensor. A  
flashing red indicator light identifies the presence of a target. After a detected  
user moves out of the effective range of the sensor, a signal is sent to the  
Flushometer Solenoid and, after appropriate arming and/or flush delays, the flush  
cycle is initiated. When a unit is used intermittently, the Sentinel Flush feature  
ensures a cleansing cycle at least once in any 24-hour period.  
NOTE: Sensor location and positioning is critical. Failure to properly position the  
electrical box to the recommended plumbing rough-in dimensions will result in  
improper installation and may impair product performance. All tradesmen  
(plumbers, electricians, tile setters, etc.) involved in the installation of this product  
must coordinate their work efforts to ensure proper product installation. Improper  
installation may nullify the manufacturer’s warranty.  
THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION  
ON THE FACE HEREOF. IN NO EVENT IS SLOAN VALVE COMPANY  
RESPONSIBLE FOR ANY CONSEQUENTIAL DAMAGES OF ANY MEASURE  
WHATSOEVER.

Maintenance Guide  
Troubleshooting Guide  
NOTE: Upon detection of the user, the red indicator light flashes slowly for a period of eight seconds. When the user leaves the detection range, the indicator light flashes  
rapidly and the Sensor initiates the flush sequence. Then the indicator light stops flashing and the valve flushes. (On water closet models, the valve will flush after  
a three-second delay).  
1. PROBLEM: Valve does not function (red light does not flash when  
user steps in front of sensor).  
3. PROBLEM: Volume of water is insufficient to adequately siphon  
fixture.  
CAUSE: No power is being supplied to sensor.  
CAUSE: Control Stop is not open wide enough.  
SOLUTION: Ensure that the main power is turned “ON.” Check  
transformer, leads and connections. Repair or replace as  
necessary.  
CAUSE: EL-1500/EL-1500-L Sensor is not operating.  
SOLUTION: Replace EL-1500/EL-1500-L Sensor.  
SOLUTION: Adjust control stop for desired water delivery.  
CAUSE: Low Consumption unit is installed on Water Saver or  
Conventional fixture.  
SOLUTION: Replace Diaphragm component parts of valve with kit  
that corresponds to appropriate flush volume of fixture.  
CAUSE: Inadequate water volume or pressure available from  
supply.  
SOLUTION: Increase pressure or supply (flow rate) to the valve.  
Consult factory for assistance.  
2. PROBLEM: Valve does not function (red light flashes when user  
steps in front of Sensor).  
INDICATOR: Red light stops flashing when user steps away and  
valve makes a “clicking” sound but does not flush.  
4. PROBLEM: Length of flush is too long (long flushing) or valve fails  
to shut off.  
CAUSE: No water is being supplied to the valve.  
SOLUTION: Make certain that water supply is turned “ON” and the  
Control Stop is open.  
CAUSE: Water Saver valve is installed on Low Consumption  
fixture.  
CAUSE: EL-128-A cartridge is fouled or jammed.  
SOLUTION: Replace Diaphragm component parts of valve with kit  
that corresponds to appropriate flush volume of fixture.  
SOLUTION: Turn electronic power to valve “OFF” (failure to do so  
could result in damage to the solenoid coil). Remove the  
solenoid operator from the valve and remove the  
CAUSE: Relief valve in diaphragm is not seated properly or  
bypass hole in diaphragm is clogged.  
EL-128-A cartridge. Clean and/or repair as necessary.  
INDICATOR: The red light stops flashing when user steps away but  
the valve does NOT make a “clicking” sound and  
does NOT flush.  
SOLUTION: Disassemble inside Diaphragm component parts and  
wash parts thoroughly. Replace worn parts if necessary.  
5. PROBLEM: Water splashes from fixture.  
CAUSE: EL-163-A solenoid shaft assembly is fouled or jammed.  
CAUSE: Supply flow rate is more than necessary.  
SOLUTION: Adjust Control Stop to meet flow rate required for proper  
cleansing of the fixture.  
CAUSE: Closet valve is installed on urinal fixture.  
SOLUTION: Replace closet Diaphragm component parts with proper  
urinal kit (Inside Diaphragm Assembly or Inside Parts Kit)  
SOLUTION: Turn electronic power to valve “OFF” (failure to do so  
could result in damage to the solenoid coil). Remove  
EL-101 or EL-166 nut from the solenoid operator.  
Remove the coil from the solenoid operator. Use a  
spanner wrench or pliers to remove the EL-163-A  
solenoid shaft assembly from valve. Clean and/or replace  
as necessary. Be sure to replace plunger spring when  
reassembling Solenoid Shaft Assembly.  
INDICATOR: The red light flashes three (3) short flashes, three (3)  
long flashes then three (3) short flashes (“S-O-S”)  
and continues to repeat this cycle even when user  
steps out of the sensor’s detection range.  
Control Stop Setting  
IMPORTANT: Never open Control Stop to where the flow from the valve  
exceeds the flow capability of the fixture. In the event of a valve failure, the  
fixture must be able to accommodate a continuous flow from the valve.  
CAUSE: EL-1500/EL-1500-L Sensor wiring connections are  
incorrect.  
SOLUTION: Rewire Sensor to valve. One solenoid lead connects to  
the “TO VALVE” connection on Sensor. One transformer  
lead connects to the “24 VAC IN” connection on Sensor.  
Second solenoid lead and second transformer lead  
connect together.  
CAUSE: Wiring to Sensor is ground shorted.  
SOLUTION: Find short in wiring circuit and correct.  
Care and Cleaning Instructions  
DO NOT USE abrasive or chemical cleaners to clean Flushometers that may  
dull the luster and attack the chrome or decorative finish. Use ONLY soap and  
water, then wipe dry with a clean towel or cloth. When cleaning the bathroom  
tile, protect the Flushometer from any splattering of cleaner. Acids and  
cleaning fluids can discolor or remove chrome plating.  
If further assistance is required, please contact Sloan Valve Company  
Installation Engineering Department at:  
CAUSE: EL-165-2 solenoid coil is burnt out or coil is not  
connected to solenoid plunger shaft.  
SOLUTION: Reinstall or replace coil as necessary.
