After understanding the automatic toilet sensor flusher RJY-30-S301AD, let’s introduce how to install it.

The unique feature of this sensor flush is that it includes a mechanical button, which is still used for flush water when the power is cut off or the sensor is not working.

Before installing automatic toilet flush valve:
(1)Please make sure to use tap water, unfiltered and treated sewage may cause damage to the device
(2)Please make sure the water outlet keeps downwards.
(3)Please avoid the installed location where sunlight or strong light will directly shine on the sensor to avoid the performance of the device is degraded.
(4)It is suggested to install the products by a licensed plumber.

Start installing automatic flush valve as the following:

Remove the anti-dust sheet from the water inlet, the wire guarder installs in one of the power holes of the embedded box as required. Connect pipes with the water inlet and outlet respectively and fix it. Then put the embedded box into the wall(the protection cover edge should parallel with the ceramic), as Figure A.

1. Unscrew the screws and remove the protection cover (as Figure B).
2. Open the battery cover and put it into 4AA standard alkaline batteries(as Figure C-1).
Connect the adapter AC220V/50HZ wire to the main power, and connect the power connector A & B (as Figures C-2, C-3), then place the adapter into the embedded box.
Connect the solenoid valve connector A & B(as Figure C-4).

Finally, use a suction cup to remove the panel, fix the IR sensor assembly to the embedded box with screws(as Figure C-5), and then cover the panel back.

Please pay attention to the installation height when you install the conceal sensor toilet flusher.

How to Use Touchless Toilet Sensor Flush:
1. When a person enters the sensing range over 2-3 seconds, the machine actuates, LED light flash one time.
2. After the person leaves 2-3 seconds, auto flush for 4 seconds(flush duration adjustable by an extra remote controller).

Water-flow regulating
When you need to adjust the water volume, use a flat blade screwdriver to adjust water volume(turn down the water volume clockwise and turn up the water volume counterclockwise).

Cleaning the filter net
Unscrew the union nuts inside the embedded box and take out the filter net. Clean the filter net with clear water and then fix it back.

Mechanical Button
When the power fails or the sensor fails, the mechanical button can be used for flushing.

Open the battery cover, replace 4AA new alkaline batteries, and fix them back (as Figure G-1).

*The polarity of the battery (positive+ and negative -) must be correct;
*DO NOT mix new & old batteries. DO NOT mix batteries of different brands.
*Please change batteries when the indicator light keeps flashing, indicating that the batteries do not have enough power.

Note for cleaning after installation:
1. Please use a damp towel or cotton cloth to wipe gently.
2. Please avoid any rocking or violent motion.
3. Please DO NOT use acid/alkaline detergents for cleaning.
