"Installation Notes: 1.Attach the magnet attached to the dual sensing probe to the normal water level of the sample or main tank, align the horizontal surface with the lower probe. 2. Connect one end of the water pipe to the DCDC water supply pump, insert the broken siphon tube into the other end. The position of the broken siphon tube is higher than the level of the reservoir and should be fixed as follows: Water Pipe Bracket 3.Connect the DC water pump and DC transformer to the controller. Please do not install the dual sensing probe in a bubble area to prevent interference and incorrect judgment. WARNING: Be careful of damage caused by strong magnets. Broken siphon pipes must be higher than the water level of the reservoir. Intake Inlet: When the refillable pump starts, air will enter the siphon breaker and block the siphon phenomenon. Drip Port: Water supply pump is normal. LED Indicator Number: (SATO-260P) Red and Blue flashing interwoven to indicate power on Blue light is fixed and standby status Blue light flashes to indicate the supplement/water pump is starting Blue light flashes quickly in a short time, and the sensor probe at the top detects changes in water level Red flashing, QST alarm, and bubble interference. Clean the probe and move the sensor to a bubble-free area. Flashing red, QST alarm, and running out of water in the reservoir. Add water to the reservoir *Troubleshooting with the above solution and unplug the power and reinsert it. **On a small tank, the upper probe may flash blue light for a short time every time the water is refilled. This is normal and will not work.
