This valve is designed for new construction or where there is easily accessed plumb-
ing for the xture and valve. This valve is designed for a minimum 6-1/2 inch (165
mm) wall space depth. Distance from the center of the valve (inlet or outlet pipe) to
the nished surface of the wall can vary from 3-1/4” – 4-1/4” (83 – 108 mm).
Wall plate opening must be a minimum of 7-3/8” wide x 8-3/8” tall (187 mm wide
x 213 mm tall) to maximum 7-5/8” wide x 8-5/8” tall (194 mm wide x 219 mm
tall). Mud plate is provided and must accompany valve for proper installation. Mud
plate is removed after wall is nished.

IMPORTANT:
• INSTALL ALL PLUMBING IN ACCORDANCE WITH APPLICABLE CODES AND REGULATIONS.
• WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN ADEQUATE VOLUME OF WATER FOR EACH FIXTURE.
• FLUSH ALL WATER LINES PRIOR TO MAKING CONNECTIONS.
Sloan’s ushometers are designed to operate with 20 to 80 psi (138 to 552 kPa) of water pressure. THE MINIMUM PRESSURE REQUIRED
TO THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED.
Consult xture manufacturer for minimum pressure requirements. Most high efciency water closets require a minimum owing pressure of 25 psi
(172 kPa). Many building codes and the ASME A112.19.2 xture standard list maximum static water pressure as 80 PSI (552 kPa).

SENSOR OPERATION
After power is applied, the Sensor Module will perform its Start-up routine for approximately 3 minutes 30 seconds with LED blinking. Step
away from sensor during this
time. Sensor will calibrate without user in detection area to calibrate "non-use" enviroment.
NOTE: A one (1) second long Red LED, followed by one slow Red LED blinking in the Sensor Window indicates sensor is in the start-up mode.
There will be two (2) Red LED pulses (each two (1) second long) in the Sensor Window to indicate the start-up routine is complete.
After the start-up routine is complete, in the rst ten (10) minutes of operation, a visible Red LED ashes in the Sensor Window of the CX
Flushometer when a user is detected.
The CX Flushometer has a factory set sensing range:
i. Water Closet Models – 22” to 46” (559 mm to 1168 mm)
ii. Urinal Models – 15” to 34” 381 mm to 864 mm)
Test sensor by stepping in front of the sensor for 10 seconds.
After 10 seconds step away from the sensor and listen for a “CLICK”
The factory setting should be satisfactory for most installations. If a range adjustment is required, refer to the range adjustment instructions in this
installation guide (See page 13).
TEST SENSOR OPERATION
Flushometer is shipped with the ow control adjustment turned OFF.
Disconnect Flushometer Solenoid connector from the Sensor Assembly. Pull on end
connector to prevent damage to wires.
Lift the Sensor Assembly Override Button up to access the activation assembly.

OPERATION
A continuous, INVISIBLE light beam is emitted from the Sloan CX Sensor.
After the user enters the beam’s effective range, 22 to 46 inches (559 mm to 1168 mm) for closet installations and 15 to 34 inches (381 mm to
864 mm) for urinal installations for ten (10) seconds the ushometer is armed.
A
B
When the user steps away, the sensor initiates a “one-time” signal that activates the ushing cycle to ush the xture (1 second delay for urinal,
3 seconds delay for closet). The Circuit automatically resets and is ready for the next user.

RESTART SENSOR (ONLY IF NECESSARY)
The Sloan CX Flushometer has a factory set sensing range:
Water Closet Models - 22” to 46” (559 mm to 1168 mm)
Urinal Models - 15” to 34” (381 mm to 864 mm)
The Factory setting should be satisfactory for most installations. If the range is too short (i.e. not picking up users) or too long (i.e., picking up
opposite wall or stall door) the range can be adjusted.
NOTE: WATER DOES NOT HAVE TO BE TURNED OFF TO ADJUST RANGE.
Make sure to remove all the non-permanent targets in sensor view area.
Push Override button for 20-30 seconds.
The Red LED in the sensor window starts slow blinking.
Release the button during the LED blinking and step away.
The CX will enter into start-up mode.
The setting mode will run for one minute.

TROUBLESHOOTING
CARE AND CLEANING
DO NOT use abrasive or chemical cleaners (including chlorine bleach)
to clean Flushometers that may dull the luster and attack the chrome or
special decorative nishes. Use ONLY mild soap and water, then wipe dry
with clean cloth or towel. While cleaning the bathroom tile, protect the
Flushometer from any splattering of cleaner. Acids and cleaning uids will
discolor or remove chrome plating.
A. Sensor Flashes Continuously Only When User Steps Within Range.
i. Unit in Start-Up mode; no problem. This feature is active for the rst ten (10) minutes of operation.
B. Valve Does Not Flush; Sensor Not Picking Up User.
i. Range too short; increase the range.
C. Valve Does Not Flush; Sensor Picking Up Opposite Wall or Surface, or Only Flushes When Someone Walks By.
Red Light Flashes Continuously for First 10 Minutes Even with No One in Front of the Sensor.
i. Range too long; shorten range.
D. Valve Does Not Flush Even After Adjustment.
i. Ensure water supply to valve is turned on.
ii. Activation Assembly sleeve is in closed position. Turn counterclockwise to open water ow. NOTE: there is approximately 1/8-turn (45°) of free
spinning as the activation assembly engages the shut-off sleeve between opening and closing the valve.
iii. Batteries completely used up; replace batteries.
iv. Problem with activation assembly; replace activation assembly.
v. Problem with Sensor Assembly; replace Sensor Assembly.
E. Red Light Blinks four (4) Times When User Steps Within Range (Battery Only).
i. Batteries low; replace batteries.
F. Red Light Blinks four (4) Times When User Steps Within Range (Hardwire and Battery).
i. Battery box not connected; connect battery box to sensor assembly.
ii. Batteries low; replace batteries.
G. Valve Does Not Shut off.
i. Metering bypass hole in piston is clogged. Remove the piston O-ring from groove and wash under clean running water.
Replace piston if cleaning does not correct the problem.
ii. Supply line water pressure has dropped and is not sufcient to close the valve. Close Activation Assembly until pressure is
restored. NOTE: under some conditions, opening the shut-off sleeve can correct the force imbalance and cause the valve close.
iii. Piston is damaged. Replace with new proper gpf/Lpf piston.
iv. Solenoid latched in open position during valve shipment. Connect sensor assembly and press override button. See "install battery box and sensor
assembly" section on page 10 for additional information.

iii. Wrong CX model installed; i.e.,1.6 gpf. model installed on 0.5 gpf/1.9 Lpf or 0.25 gpf/1.0 Lpf urinal xture. Replace
with proper CX model per guide.
I. Not enough water to Fixture.
i. Activation Assembly not adjusted properly. Readjust Activation Assembly by turning counterclockwise.
ii. Wrong CX model installed; i.e. 0.5 gpf. urinal installed on 1.6 gal. closet xture. Replace with proper CX model.
iii. Water supply pressure is inadequate (low). Increase the water supply pressure. Contact the xture manufacturer for
minimum water supply requirements of the xture.
J. Chattering noise is heard during flush.
