  • Mount the Sensor Assembly to the wall bracket.

    • Aligned the four (4) slots on the sensor assembly with the mounting pegs on the wall bracket.
    • Slide the sensor assembly all the way down

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 the sensor during this time. The sensor will calibrate without the user in the detection area to calibrate the “non-use” enviroment.
    NOTE : It is important to leave the area directly in front of the sensor during calibration (exit stall or stand to the side). Failure to do so may cause the sensor to not operate and require restarting the sensor again until calibration is properly performed. Disconnect power from the sensor for 1 minute before repeating.
    NOTE : A one (1) second long Red LED, followed by one slow Red LED blinking in the Sensor Window indicates the sensor is in the start-up mode. There will be two (2) Red LED pulses (each one (1) second long) in the Sensor Window to indicate the start-up routine is complete.

  • After the start-up routine is complete, in the first ten (10) minutes of operation, a visible Red LED flashes in the Sensor Window of the CX Flushometer when a user is detected.

TEST SENSOR OPERATION

The CX Flushometer has a factory-set sensing range:

  1. Water Closet Models – 22” to 46” (559 mm to 1168 mm)
  2.  Urinal Models – 15” to 34” 381 mm to 864 mm)

Test the 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).

ADJUST WATER FLOW

  • Flushometer is shipped with the flow control adjustment turned OFF.
  • Disconnect the Flushometer Solenoid connector from the Sensor Assembly. Pull on the end connector to prevent damage to wires.
  • Lift the Sensor Assembly Override Button up to access the activation assembly.
  • Open water flow by turning the activation assembly slowly COUNTERCLOCKWISE using an adjusting tool and a screwdriver or a wrench.
    • 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.
    • A 1-1/2″ socket or wrench can be attached to the adjustment tool or a screwdriver can be passed through the side holes to provide additional torque.
  • Connect the Flushometer Solenoid connector to the Sensor Assembly.
  • Activate Flushometer by pressing the Override Button.
  • Adjust the Activation Assembly after each flush until the flow rate delivered properly cleanses the fixture (turn CLOCKWISE to lessen flow and COUNTERCLOCKWISE to increase flow).

INSTALL WALL PLATESLOAN-CX-8158-1-6-Sensor-Closet-and-Urinal-
Flushometers-fig- \(33\)

  1. Make sure the retaining screw on the bracket is fully tightened clockwise.
  2. Slide Sensor Assembly all the way up.
  3. Align the Wall Plate cut out with the window and Override the Button of the Sensor Assembly and push Wall Plate all the way in.
  4. Make sure the sensor window and button are sitting inside the wall plate cut out. Slide Wall Plate all the way down.
  5. The retaining screw is designed to rest inside the wall plate. Turning the retaining screw counterclockwise using supplied Allen key until it touches the wall plate will lock the plate in place, preventing the plate from sliding upward and being removed.
  6. Make sure Wall Plate doesn’t slide up.

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 flushometer is armed.
  • When the user steps away, the sensor initiates a “one-time” signal that activates the flushing cycle to flush the fixture (1-second delay for urinal, 3 seconds delay for closet). The Circuit automatically resets and is ready for the next user.

RESTART THE 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 THE RANGE.

  • Make sure to remove all the non-permanent targets in the sensor view area.
  • Push the Override button for 20-30 seconds.
  • The Red LED in the sensor window starts slowly blinking.
  • Release the button after the LED starts slowly blinking and step away.
  • The CX will enter into start-up mode.
  • The setting mode will run for one minute.
