Troubleshooting Guide

NOTE:
rapidly
SOLUTION: Ensure that the main power is turned "ON." Check
transformer, leads and connections. Repair or replace as
necessary.
SOLUTION: Replace EL-1500/EL-1500-L Sensor.
INDICATOR: Red light stops flashing when user steps away and
valve makes a "clicking" sound but does not flush.
SOLUTION: Make certain that water supply is turned "ON" and the
Control Stop is open.
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
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: 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.
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.
SOLUTION: Find short in wiring circuit and correct.
SOLUTION: Reinstall or replace coil as necessary.

stops
SOLUTION: Adjust control stop for desired water delivery.
SOLUTION: Replace Diaphragm component parts of valve with kit
that corresponds to appropriate flush volume of fixture.
SOLUTION: Increase pressure or supply (flow rate) to the valve.
Consult factory for assistance.
SOLUTION: Replace Diaphragm component parts of valve with kit
that corresponds to appropriate flush volume of fixture.
SOLUTION: Disassemble inside Diaphragm component parts and
wash parts thoroughly. Replace worn parts if necessary.
SOLUTION: Adjust Control Stop to meet flow rate required for proper
cleansing of the fixture.
SOLUTION: Replace closet Diaphragm component parts with proper
urinal kit (Inside Diaphragm Assembly or Inside Parts Kit)
Control Stop Setting
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.
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.
