INSTALL BATTERY BOX AND SENSOR ASSEMBLY (CONT.)

!!! NOTE !!!
THE SENSOR ASSEMBLY COMES WITH THE BUTTON ALREADY INSTALLED. IN CASE THE BUTTON HAS COME OFF FROM THE SENSOR ASSEMBLY DURING SHIPMENT, INSTALL IT FOLLOWING THE FIGURE BELOW.

SENSOR OPERATION

A. After power is applied, the Sensor Module will perform its Start-up routine for 15 seconds with LED blinking.
NOTE: A three (3) seconds long Red LED, followed by 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 (2) seconds long) in the Sensor Window to indicate the start-up routine is complete.
B. 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 TruFlush Flushometer when a user is detected.

TEST SENSOR OPERATION

The TruFlush 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)
A. Test sensor by stepping in front of the sensor for 10 seconds.
B. 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 Section 9).

ADJUST WATER FLOW

Flushometer is shipped with the flow control adjustment turned OFF.
A. Disconnect Flushometer Solenoid connector from the Sensor Assembly. Pull on end connector to prevent damage to wires.
B. Lift the Sensor Assembly Override Button up to access the activation assembly.
C.Open water flow by turning activation assembly slowly COUNTERCLOCKWISE using adjusting tool and a screwdriver or a wrench.

!!! NOTE !!!
MAKE SURE SOLENOID CONNECTOR GOES THROUGH THE CENTER OF THE ADJUSTING TOOL TO AVOID DAMAGE TO THE CABLE.

D.Connect Flushometer Solenoid connector to the Sensor Assembly.
E. Activate Flushometer by pressing the Override Button.
F. Adjust Activation Assembly after each flush until the flow rate delivered properly cleanses the fixture (turn CLOCKWISE to lessen flow and COUNTERCLOCKWISE to increase flow).

!!! NOTE !!!
MAKE SURE FLUSHOMETER SOLENOID CONNECTOR IS DISCONNECTED FROM SENSOR ASSEMBLY EVERY TIME BEFORE ROTATING ACTIVATION ASSEMBLY.
!!! NOTE !!!
UNDER NO CIRCUMSTANCES SHOULD THE SOLENOID BE REMOVED OR ADJUSTED.
!!! IMPORTANT !!!
THE FLUSHOMETER IS ENGINEERED FOR QUIET OPERATION. EXCESSIVE WATER FLOW CREATES NOISE, WHILE TOO LITTLE WATER FLOW MAY NOT SATISFY THE NEEDS OF THE FIXTURE. PROPER ADJUSTMENT IS MADE WHEN PLUMBING FIXTURE IS CLEANSED AFTER EACH FLUSH WITHOUT SPLASHING WATER OUT FROM THE LIP AND A QUIET FLUSHING CYCLE IS ACHIEVED.
!!! IMPORTANT !!!
THE ACTIVATION ASSEMBLY SHOULD NEVER BE OPENED TO THE POINT 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.

INSTALL WALL PLATE

Flushometer is shipped with the flow control adjustment turned OFF.
A. Make sure retaining screw on bracket is fully tightened
B. Slide Sensor Assembly all the way up.
C. Align Wall Plate cut out with the window and Override Button of Sensor Assembly and push Wall Plate all the way in.
i. Make sure sensor window and button are sitting inside the wall plate cut out.
D. Slide Wall Plate all the way down.
E. Unscrew the retaining screw using supplied Allen key until it touches wall plate.
F. Make sure Wall Plate doesn’t slide up.

!!! NOTE !!!
DO NOT UNSCREW ANYMORE ONCE SCREW TOUCHES WALL PLATE.

OPERATION

A. A continuous, INVISIBLE light beam is emitted from the TruFlush Sensor.
B. 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.

C. 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.

RANGE ADJUSTMENT (ADJUST ONLY IF NECESSARY)

The TruFlush 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.
A. Make sure to remove all the non-permanent targets in sensor view area.
B. Push Override button for 20-30 seconds.
C. The Red LED in the sensor window starts slow blinking.
D. Release the button during the LED blinking.
E. The TruFlush will enter into distance setting mode.
F. The setting mode will run for one minute.

!!! IMPORTANT !!!
WHEN ADJUSTING RANGE FOR CLOSET SENSOR, MAKE SURE THE CLOSET DOOR IS ALL THE WAY CLOSED FOR PROPER RANGE  ADJUSTMENTS.
!!! IMPORTANT !!!
WHEN ADJUSTING RANGE FOR URINAL SENSOR, MAKE SURE TO SET-UP A PROPER TARGET IN FRONT OF URINAL SENSOR FOR PROPER RANGE ADJUSTMENTS
