Notice:
.
a.
See the figure
right for rough-in dimension requirement.
While installing 744T-C05(AC),chisel out the slot indicated
in the dot line area of figure right for installation of bushing.
Determine the installation location per rough-in dimensions
and the table of installation position. Chisel out a slot and
install the supply tubes. Then flush the supply tubes. The
depth of the slot is not less than 105 mm, see the figure to
the right for rough-in dimension requirement.
Installation that fails to accord with the
installation position or rough-in dimensions
may result in false operations or no
operations.
b. No light shall enter or be reflected into the
sensing window.
c. reflectible objects in front of the sensing
window (e.g., mirror, polishing stainless
steel and some other polished plates).

Automatic Adjustment of Sensing Distance
The accuracy of this section s steps will affect
the sensing performance.
The sensing distance of this product is set at within 100cm
away from the sensing window along the direction of
transmitting angle (with a 30cm x 30cm white board as the
reflecting surface) in the factory with an infrared transmitting
angle of about 27 (37 when an angle-converting piece
installed)downward. When the power is applied, the product
is in the status of automatically adjusting its sensing distance
during the first ten minutes, when the sensor is in an
environment of normal operations. Also during this period, all
the facilities have been installed in the toilet. Proceed with
this process so that you can correctly adjust its sensing
distance.

1. Preparations
a. Pull down the toilet seat, if there is a cover, please lift it as
shown in picture above.
b. Remove any unwanted materials near the toilet bowl.
c. Set up the flashing volume of the sensor via the switches of
the flushing volume (see the following setup of the flashing
volume).
2. Procedures (Please finish below
steps within 5 mins)
a.
b. Unplug 3-pin connector of speed detector, then connect
switch assy. and control box with 3-pin connector. Unplug
them after 10 seconds, and replug speed detector and
control box with 3-pin connector.(Please ignore this step if
the flush volume is the same as default setting.)
c. Install the sensor cover.
d. Close the door of the toilet.
e. Wait 5 mins, the auto adjustment of sensing distance will
complete.
Reomove the sensor cover. While installing 744T(DC), take
out the battery box from the back of the cover and put
batteries into the box. Connect battery box assy to control
box. While installing 744T-C05(AC),connect AC power unit
to control box, and then power on.

4. Manual Flushing
This system can have a good sense toward most of the
clothes. However, it may have abnormal sense to a very small
number of clothes. If this occurs, you may use the mode of
manual flushing. Press the button with your hand to flush the
toilet bowl with water, or loosen the button to stop flushing.
a. The button is a standby device that will be
used when the sensor cannot perform
correctly or the toilet is being repaired. It is
not recommended to use when the sensor
is normally functional.
b. When the sensor cannot function properly,
please refer to the list of troubleshooting on
Page 17.
c. Do not exert too much force to avoid the
manual unit from damaged.

5. Adjustment of Flushing Volume
When the water pressure is 0.10 ~ 0.55 MPa, the device may
normally automatically control the flushing volume. If
sometimes splashs, you can reduce the water flow. And if the
flushing peformance is not good, you can enlarge the water
flow. When adjusting, remove the sensor cover and turn the
adjusting bolt for water flow till good flushing and no splash.
Adjusting Bolt
6. Replacement of Batteries(only for 744T)
When the power in the batteries will be exhausted and the
indicator in the sensing window continues flashing, the
system reminds you of replacing the old batteries with new
ones. When out of power, the indicator will flash every 2
seconds and the sensor will not work until new batteries are
supplied. When changing, remove the battery cover and put
in new batteries. If the system has been powered off for a
long time, you must reset the procedure after the replacement
of batteries and the system will readjust automatically its
sensing distance (refer to the section of automatic adjustment
of sensing distance).
the flash direction of the indicator is downward,
so you need to observe along the direction.
