accessed plumbing for the xture and the valve.
This valve is designed for minimum six inch (152 mm) wall space
depth. Distance from center of the valve (inlet or outlet pipe) to the
nished surface of the wall can vary from 2”-3” (51-76 mm).

Wall plate opening must be of 5.6” x 5.6” (142 x 142 mm). Mud plate
is provided and must accompany valve for proper installation. Mud
plate is removed after wall is nished.

TOOLS REQUIRED FOR INSTALLATION

3. 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.

4. 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 rst ten (10) minutes of operation, a visible Red LED ashes in the Sensor Window of the TruFlush
Flushometer when a user is detected.

5. TEST SENSOR OPERATION

The TruFlush has a factory set sensing range:
i. Water Closet Models – 22” to 31” (559 mm to 787 mm)
ii. Urinal Models – 9” to 21” (229 mm to 533 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).

6. ADJUST WATER FLOW

Flushometer is shipped with the ow control adjustment turned OFF.

A. Disconnect Flushometer Solenoid connector from the Sensor Assembly
B. Lift the Sensor Assembly Override Button up to access the activation assembly.
C.Open water ow 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 ush until the ow rate delivered properly cleanses the xture (turn CLOCKWISE to lessen ow and
COUNTERCLOCKWISE to increase ow).

MAKE SURE FLUSHOMETER SOLENOID CONNECTOR IS

DISCONNECTED FROM SENSOR ASSEMBLY EVERY TIME

BEFORE ROTATING ACTIVATION ASSEMBLY.

UNDER NO CIRCUMSTANCES SHOULD THE SOLENOID BE

Pass Solenoid Cable

!!! NOTE !!!

!!! NOTE !!!

REMOVED OR ADJUSTED.

through to avoid damage

!!! IMPORTANT !!!

THE FLUSHOMETER IS ENGINEERED FOR QUIET OPERATION.

EXCESSIVE WATER FLOW CREATES NOISE, WHILE TOO

Increase Flow

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.

Decrease Flow

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.

8. 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 31 inches (559 mm to 787 mm) for closet installations and 9 to 21 inches (381 mm

to 762 mm) for urinal installations for ten (10) seconds the ushometer is armed.

C. 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.

9. RANGE ADJUSTMENT (ADJUST ONLY IF NECESSARY)

The TruFlush has a factory set sensing range:
Water Closet Models - 22” to 31” (559 mm to 787 mm)
Urinal Models - 9” to 21” (229 mm to 533 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.

WHEN ADJUSTING RANGE FOR CLOSET SENSOR, MAKE
SURE THE CLOSET DOOR IS ALL THE WAY CLOSED FOR

WHEN ADJUSTING RANGE FOR URINAL SENSOR, MAKE SURE
TO SET-UP A PROPER TARGET IN FRONT OF URINAL SENSOR

FOR PROPER RANGE ADJUSTMENTS
