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 top buon ushing 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.

Installaon Instrucons:
Applicable to central-pressing type
toilets, the inside ush buon as
shown in gure 1—with low/large
water volume buon or single ush
buon.
Li the toilet tank cover and then ip
to the inside.
Unscrew the xing buon on the tank
cover. (If your toilet or buon style is
dierent from gure above, please
refer to the instrucon manual for
your toilet to remove ush buon.)
Remove the original ush buon and
store somewhere safe.
Put the tank cover back on. Take out the (10) Depth Ruler and
measure the distance from top of the
Flush Buon hole to top of the inter-
nal buon on the Flush Valve.
Place the (10) Depth Ruler in buon
hole & press downward slowly by
moving the P-Ruler to touch the top
of the internal buon on the Flush
Valve.
Remove the (10) Depth Ruler that has
been measured (Arrows in gure 8
represent total length of (8) blocks to
assemble.)
Take out the (8) Blocks and (9) Spin
Washers.

Installaon Instrucons:
Please assemble the (8) Blocks and (9)
Spin Washers together according to
length that was measured by (10)
Depth Ruler. Note: (8) Blocks come in
dierent sizes, use as necessary, align
to notch at top.
Completed Assembly Remove the (7) Fixing Gasket by un-
screwing an-clockwise, and take

ing clockwise.
The assembly (8) Blocks should be
vercally inserted into the centre of
the (5) Flush Motor hole.
Replace the tank cover gently and
check if boom of assembly (8) Blocks
on (5) Flush Motor, just touch the top
of the internal buon. Appropriately
readjust the (8) Blocks. If tank cover is
plasc, use the (12) Transparent Sck-
ers on all sides between tank cover
and tank body to prevent cover liing.
Pull out the (13) installaon scker,
tear o the small scker on inside of
the doed box and paste it around
the toilet used as sign of warning.
Align the boom edge of (13) installa-
on demonstraon scker to the top
edge of toilet lid, and ax to the wall.

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.
