1. Unscrew the two screws on the protection box with a screwdriver and take out the protective box after
the main machine is put into the wall according to the installation requirements and the wall is tiled.
2. Suck it with a sucker or gently push it straight from the back with your hand to remove the stainless
steel panel sucked on the face frame.
3. Connect the black male plug of the electric eye with the black female plug of the solenoid valve. Con-
nect the red male plug of the power supply or battery box with the red female plug of the electric eye. (for
AC and DC products, the red male plug of the battery box is connected with the red female plug of the
power supply).
4. Put the face frame on the installation position of the wall, then put four M4*40 machine screws through
the mounting holes on the four corners of the face frame and face the screw holes on the main box.
Tighten the screws with a screwdriver to make the face frame firmly installed without loosening.
5. After fixing the face frame, place the stainless steel panel on the corresponding position of the face
frame. Let the magnet on the face frame tightly attract it, so that it cannot loose and fall.

ceramic tiles ceramic tiles
after installation, check the connec-
tion of the power line, and then have
several times try to flush water.
1.Operation method
2.Precautions for operation
1) When the user enters the sensing area, the sensor will conduct the first stage of pre flushing
after sensing for 3 seconds, and then the sensor will be effective after sensing for 3 seconds.
When the user leaves the sensing area for 3 seconds, the second stage of cleaning and
flushing will be carried out (this flushing time can be set by the remote control within 2 seconds
to 15 seconds); If users use it continuously within one minute, the first stage of pre flushing will
not be carried out, and only the second stage of cleaning and flushing will be carried out after
the user leaves (environmental protection and water-saving design). The sensor will be auto-
matically cleaned and flushed once without being used for 24 hours. The sensing distance of
the sensor can be adjusted within the range of 30cm to 80cm; The factory default sensing
distance is set to 55cm.
2) For products with manual pressing function, the users can push the manual button to flush
the urinal when the AC power supply is cut off or the DC battery is exhausted, or other abnor-
malities occur leading to the automatic induction failure.
1）In order to avoid the possibility of failure, do not install the product in front of stainless steel
walls and other high-strength reflective surfaces or other infrared sensors.
2）If you need to use it in special environments such as dark black clothes with high intensity
reflection or easy absorption of infrared rays, please consult the supplier to choose anti color
difference sensor products to achieve the best effect

VII Function adjustment
Note:
Note:
3. The standby power supply of DC products and AC / DC products must be replaced
with a new dry battery after the power is exhausted (as shown in the figure below)
3）If there is dirt in the induction eye window, please clean it in time to avoid affecting the use
effect.
4）If you find that the use effect is not good during use, please operate according to "VII:
function adjustment"
5)If you find that the flushing water is insufficient during use, please clean the filter.
6) For DC type (dry battery) products, when the dry battery voltage is lower than about 4.5V,
the indicator light will be red when the sensor eye has induction, indicating that the dry battery
voltage is insufficient and the battery needs to be replaced.
7) If you find that the AC type urinal flushing sensor is not inductive or the power supply is in
poor contact, please turn off the power immediately and find relevant professionals for mainte-
nance to avoid electric shock or other accidents.

Battery box cover
No.5 dry battery rack
when replacing dry batteries, correctly install four 1.5V
alkaline No. 5 dry batteries into the battery rack according
to the "+" "-" mark on the battery rack, then put the battery
rack into the battery box and fasten the cover of the battery
box. Old and new batteries cannot be mixed.
Remove the panel and adjust the function according to the installation method of the panel.
1. Water volume adjustment
Adjust water consumption .Firstly remove the panel and
adjust the regulating valve with a "straight" screwdriver
(as shown in the figure). Turn left to increase the water
volume and right to decrease water volume. (some types
of panels need to remove the lower frame before using
the screwdriver to adjust the regulating valve, and the
adjustment method is the same)

VIII Maintenance and precautions
2. Adjustment of sensing distance and flushing time
1. Cleaning
2. Clean the filter
3. It is strictly forbidden to wash with water directly
4. Do not use corrosive cleaners
The sensing distance and flushing time of urinal flushing sensor have been set to the best use
state when leaving the factory. If you need to change it, you can use a special remote control to
adjust it. For details, please consult the customer service center or dealer of the company
If there are obstacles or dirt in front of the induction
window that will affect the normal induction, the
obstacles must be cleared and the induction window
must be cleaned in time
Adjust the regulating valve to turn off the water
source with a "-" screwdriver, unscrew the filter,
clean it with a toothbrush, and then re-install it.
Since the host machine contains electronic control
circuits, it is strictly forbidden to wash the surface
directly with water to prevent accidents
Do not use corrosive cleaners so as not to damage
and affect the appearance when cleaning applianc-
es,because plastic or stainless steel products are
used for panels and induction windows.
