Know ATO One 2
ATO One 2 is an automatic top-off device, which is an upgraded version of ATO One. It
adopts a more compact and accurate optical liquid level sensor and a submersible
pump with anti-dry function. There are two versions to choose from: submersible
pump version and solenoid valve version.
model Application
ATO One 2 SE Equipped with submersible pump as standard, suitable for
occasion when using water container
ATO One 2 for RO Equipped with solenoid valve as standard, suitable for the
occasion where using the RO water system
ATO One 2 SE ATO One 2 for RO
Features
Just install the sensor and submersible pump (solenoid valve), power on and use it.
The sensor is attracted by magnet, which is very convenient to install and adjust
the position.
Equipped with 2 optical liquid level sensors, the blue liquid level sensor monitors
the water level to decide whether to refill the water, and the red liquid level sensor
monitors the water level to prevent the overflow.

Rich status indications, when the replenishment overflows, the replenishment
times out, the submersible pump (solenoid valve) is not plugged in, and the
freshwater container is short of water, there will be an indicator light and a buzzer
alarm to remind you.

Installation
ATO One 2 SE

1. Install the blue sensor (S1) at the normal water level for water replenishment
detection. Note that the optical liquid level sensor should be kept away from air
bubbles, otherwise it will be disturbed and cause misjudgment;
2. Install the red sensor (S3) above the normal water level line for anti-overflow
detection. If the water level reaches this position, it means that the replenishment
sensor (S1) has failed, and the device will alarm and force the refill pump to stop
working;
3. Connect the pipeline (Submersible pump - Siphon break - Tube holder). Pay
attention to install the siphon break in the freshwater container, and ensure that it
is higher than the highest liquid level of the freshwater container at all times,
otherwise siphon cannot be prevented; the water outlet of the water pipe must be
higher than the liquid level of the fish tank;
4. Plug the submersible pump plug into the Pump connector. Note that the
anti-dry-burning identification sensor of the submersible pump must be kept
upward, only in this way can it be identified and alarmed in time when the water in
the container is insufficient.
5. Insert the power adapter plug into the DC12V connector and power on the power
adapter.

faulty
1. Check the connection of the
submersible pump (solenoid valve)
2. If the problem is not solved in step 1,
replace the submersible pump (solenoid
valve)

Overflow
1. Check if the overflow sensor (S3) is
installed correctly
2. After cleaning the sensor optical probe,
put it in water, if the water is still
replenished, the sensor is damaged
buzzer and red light
on for 1 second, off
for 1 second

Timeout
1. Check the sensor for dirt or foreign
objects
2. Power off and restart
Notes
Please use the power adapter that comes with the product and work in the
specified working environment.
The sensitivity of the optical liquid level sensor is easily affected by dirt, please
wipe off the dirt on the sensor probe in time.
The bottom fixed base of the submersible pump with filter cotton can be flexibly
removed.
The height difference between the freshwater container and the tank should not
exceed 1.5 meters, and the liquid level of the freshwater container should not be
higher than the tank level.
This product is not waterproof, please use it in an environment with a temperature
of 0-40°C and a humidity of <80%
