Sensor Appearance and Instrucon:
A. SET UP MODE (le) - Adjust the Half/Low ush cycle me by holding a
magnec wand (part 13) against the right side (D) circular magnec target unl
the desired water release is achieved. Note the speed and distance of ush
motor up/down cycle and adjust accordingly.
B. PRESENCE DETECTION - A computerised Sensor measures the “me-at-the
-toilet” and then acvates a ush motor inside the tank which lis the ush
lever for either a half/low-ush or full/large ush as required.
C. LOW BATTERIES - It will ash when the baery is low, please replace the
baery.
D. MAGNETIC TARGET (half/low ush)
NOTE 1: Aer setup is complete, if the half ush water volume is insucient or
too much (based on personal demand), simply repeat the Set Up Mode instruc-
ons located above at A. The memory model of sensor must be reset aer re-
placing baeries.
NOTE 2: When computerised Sensor starts to measure the “me-at-toilet” the
Sensor presence detecon LED will ash for 10 seconds above (maximum ush
cycle: 10 secs) by standing in front of the Sensor which then acvates a ush
motor inside the tank which lis the ush lever for either a half/low ush or
full/large ush as required.

Precauons:
1. This electronic dual-ush toilet conversion system ts most side-pressing toilets.
2. The Sensor has the funcon of self-learning, determining whether the sensor distance has at least 100 cm
above to the wall or any obstacles, otherwise it will shorten the detecon to just 40-50cm.
3. Upon powering up the Sensor will automacally detect the distance in 1 min, the Sensor presence detecon
LED will ash, please keep any obstacles or mirrored surfaces out of the detecon beam at least 100cm dur-
ing detecng to prevent false direcon and random ush.
4. The Sensor must not be obstructed by any reectors, such as mirrors, glossy bright objects etc. as they can
cause the distance to reduce to 30cm.
5. Please keep the detecon window clean, any dirt, smudges or water drippings will aect the sensivity of the
sensor.
6. Anyme the baeries (6 standard AA alkaline) are replaced or the Sensor range needs to be recalibrated,
simply repeat reseng. To prevent from false detecon and random ushing, keep any obstacles or mirrored
surfaces out of the detecon beam.

dierent you can sll install as long as
you have the parts listed above.
Take out the (6) e rod.
Align (6) Tie Rod to the bolt hole of
the (5) ush motor.
Place the end of the (6) e rod inside
square groove of (5) ush motor.
Push the (7) bolt into the centre to
secure the e rod.
Choose appropriate (9) O-rubber
washer (thick or thin) to t (A) over-
ow tube of ush valve.
Put (9) O-rubber washer on over the
(A) overow tube, and place the
smaller inner ring lip face up.
Place the (8) xing ring’s triangle face
up, then put the xing ring on, over

Installaon Instrucons:
Use the snap to secure the (8) Fixing
Ring.
Place the (5) ush motor as close to the
top of the usher valve, and set (6) e
rod towards (B) apper. If tank is dier-
ent from gure 11; adjust the posion
of the mul-direconal xing hole on
the outer ring of the ush motor to the
bolt on the xing ring.
Top-down inserng the bolt into the

on demonstraon scker to the top
edge of toilet lid, and ax to the wall.
Remove the (4) Back plate and align
with the groove in the middle of (12)

not closed.
Fixed obstacles (such as toilet paper) with-
in 10cm of the front of the sensor
Please remove the obstacles and keep the distance of 130cm
or more. The system will automacally reset and return to
normal aer 30 minutes.
The sensor detects obstacles or reecve
objects (mirrors, walls, boards, cabinets or
various xtures)
Please remove obstacles mirrors or reecve objects and
keep a distance of at least 130cm
Sensing / Power
indicator blinks
connuously
The sensor is placed too low and is
blocked by the toilet cover.
Please adjust the sensor posion so that the sensor window
exceeds the top edge of the toilet lid.
When the system is automacally set, it
senses someone or a dynamic object.
Take out baeries rst, wait for 30 minutes, then reload it, let
the sensor automacally set again, make sure there is no ob-
ject within 130 cm in front of the sensor.
Sensor surface has stains Please be careful to avoid scratching, so as not to aect the
infrared sensing distance.
The toilet in which the sensor is installed is
less than 130 cm from the wall.
A toilet with a minimum of 130 cm or more from the wall in
front of the sensor can be used.
Bad Baery Please replace the baery
Baery Life is too
short Lack of power Please replace the baery (use the lithium or alkaline baery
produced within half a year to maintain the best use me).
Not sensing or
need to be very
close
Sensing window surface with stains or
water droplets
Gently wipe the sensor window to avoid scratching, so as not
to aect the sensing window
There is an obstacle in front of the sensor
when it is automacally set for the rst
me.
Take out the baery rst, wait for 30 minutes, then re-load it,
let the sensor automacally set again , make sure there are
no obstacles within 130cm of sensor.
