Page 3 ➢ How to set up the siphon break properly? First, make sure the siphon break is in the reservoir and higher than the water level. Therefore, the drops can go back to the reservoir and break the siphon. The siphon break should be placed in the area between the two red lines as the image below.
Page 4 ➢ Why there is water drops from the siphon break when the pump is on? It is a normal phenomenon. The small hole allows air in to cut the water flow when the pump turns off. If there is no water drops, please check if the hole is clogged.
Page 5 ➢ What will happen if the siphon break is not set up properly? ⚫ If the siphon break is not set inside the reservoir. E.g., between the tank/sump and the reservoir or inside the tank/sump, the water drops from the hole of siphon break cannot flow back into the reservoir.
Page 6 ➢ Can Smart ATO Duo G2 still work if the glass is not transparent? Yes. Since the water level senor of Smart ATO Duo G2 is inside the tank/sump, the glass color will not influence its detection.
Page 7 ➢ Can I fix the tube holder on a rimmed tank/sump? Yes. You can pull out the ring of the tube holder and install it on another nail to fix it on a rimmed tank/sump.
Page 8 ➢ Where should I place the sensor? Place the sensor to the water level you desired. *Please note : Set the sensor away from water outlet and direct light to avoid bubble interference or malfunctions.
Page 9 ➢ How to use other pumps with Smart ATO Duo G2? You can use a pump which meets your requirement with our Smart AC Switch: http://autoaqua.com.tw/en/accessories/SAC-10.html Just connect Smart AC Switch with the controller, then plug the pump's power adapter in it.
Page 10 ➢ Can I use the solenoid valve with Smart ATO Duo G2? How to install it? Yes. The pump can be replaced to solenoid valve. It is recommended using with filtered water instead of tap water, or it will be clogged. Please refer to the installation diagram below.
Page 11 You can use the extension cable. We have 6.7 ft (200 cm) and 16.7 ft (500 cm) available. ⚫ Extension Cable of Power Adapter (200cm) http://autoaqua.com.tw/en/accessories/DC-212.html ⚫ Extension Cable of Power Adapter (500cm) http://autoaqua.com.tw/en/accessories/DC-215.html ⚫ Extension Cable of DC Refill Pump & Solenoid Valve (200cm) http://autoaqua.com.tw/en/accessories/DC-252.html...
Page 12 ➢ How to purchase accessories? Please contact our local distributors : http://autoaqua.com.tw/en/distributors.html...
Page 13 ➢ Why does Smart ATO Duo G2 work constantly? If the water outlet is in the water and the water level of the tank/sump is higher than level of the reservoir, the water will flow back into the reservoir (back siphon), and trigger the ATO constantly.
Page 14 ➢ Why is the pump head not high enough? ⚫ One of the possibilities is that the water inlet of the pump is too close to the wall of the reservoir. It is recommended to keep the pump away from the wall of the reservoir at least 2 inches.
Page 15 ➢ Does Smart ATO Duo G2 have a failsafe mechanism to prevent overfilling? Yes. Smart ATO Duo has a failsafe sensor (top sensor) Quick Security Technology (QST) to prevent overfilling. Once the failsafe sensor detects water, it will stop the pump and flash orange with 3 beeps as a reminder*.
Page 16 ➢ Why is the water level always a little higher than the sensor? Is the sensor broken? There are several possibilities: ⚫ The siphon break is not installed properly or clogged. ⚫ The water inlet and the sensor are not in the same reservoir.
Page 17 ➢ Why isn’t work when water level is lower than sensor? There are several possibilities: ⚫ There is some algae on the sensor. Please clean the sensor with soft brush. ⚫ The sensor is too close to the water outlet. Please set the sensor away from water outlet to avoid bubble interference.
Page 18 ➢ Is there an alert when the reservoir is empty? Yes. When the reservoir is empty, no water is refilled in the tank/sump which will cause the refilling time 6 times longer than the first time. Consequently, it will trigger an alarm and shut the pump off.
Page 19 ➢ Why does the controller flash blue and orange with audible alert? I have checked the water reservoir and the bubble but there was no problem. The QST memory is not set correct. Please unplug the power cable, mount the sensor at the normal water level before connecting the power again and do not move it afterwards.
