Sloan 150 ES-SM Optima ES-SM Concealed Surface Mount Flushometer - Manual (Page 7)

1. A continuous, invisible light
beam is emitted from the
OPTIMA Sensor.
2. When a user enters the
beam’s effective range, the
beam is reflected into the
OPTIMA’s scanning window
and transformed into a low
voltage electrical signal that
activates a ten-second time
delay circuit. The time delay
circuit eliminates false
operation from passers-by in
the rest room. Once the time
delay is completed, the
output circuit is alerted and
continues in a “hold” mode
for as long as the user
remains within the effective
range of the sensor.
3. When the user steps away
from the OPTIMA Sensor,
the loss of reflected light
initiates an electrical “one-
time” signal that energizes
the Solenoid Operator, and
activates the Flushometer to
flush the fixture. This occurs
approximately three (3)
seconds after indication.
This delay is built into the
Sensor to help prevent false
flushing due to movement
by the user. The circuit then
automatically resets and is
ready for the next user.

DO NOT use abrasive or chemical cleaners (including chlorine bleach) to
clean Flushometers as they 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.
While cleaning the bathroom tile, the Flushometer should be protected from
any splattering of cleaner. Acids and cleaning fluids can discolor or remove
chrome plating.
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.
!!! IMPORTANT — Control Stop Setting !!!

CARE AND CLEANING
TROUBLESHOOTING GUIDE
NOTE: Upon detection of the user, the red indicator light is steadily on for a
period of eight seconds. When the user leaves the detection range, the
indicator light will turn off and the Sensor initiates the flush sequence. Then
the indicator light stops flashing and the valve flushes. The valve will flush
after a three-second delay.
1. PROBLEM: Valve does not function (red light does not turn on when user
steps in front of sensor).
CAUSE: No power is being supplied to sensor.
SOLUTION: Ensure that the main power is turned “ON.” Check
transformer, leads and connections. Repair or replace as
necessary.
CAUSE: Sensor is not operating.
SOLUTION: Replace Sensor.
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.
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: EL-128-A cartridge is fouled or jammed.
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 does not turn off when user steps away and the
valve does NOT make a “clicking” sound and does NOT flush.
CAUSE: EL-163-A solenoid shaft assembly is fouled or jammed.
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.
3. PROBLEM: Volume of water is insufficient to adequately siphon fixture.
CAUSE: Control Stop is not open wide enough.
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.
4. PROBLEM: Length of flush is too long (long flushing) or valve fails to shut
off.
CAUSE: Water Saver valve is installed on Low Consumption fixture.
SOLUTION: Replace Diaphragm component parts of valve with kit that
corresponds to appropriate flush volume of fixture.
CAUSE: Relief valve in diaphragm is not seated properly or bypass hole
in diaphragm is clogged.
SOLUTION: Disassemble inside Diaphragm component parts and wash
parts thoroughly. Replace worn parts if necessary.
5. PROBLEM: Water splashes from fixture.
CAUSE: Supply flow rate is more than necessary.
SOLUTION: Adjust Control Stop to meet flow rate required for proper
cleansing of the fixture.
