ATO One 2 for RO
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 refill sensor (S1)
has failed, and the device will alarm and force the solenoid valve to stop working;
3.
Connect the pipeline (RO water system - solenoid valve - tube holder). Plug the
solenoid valve plug into the Pump connector.
4.
Insert the power adapter plug into the DC12V connector and power on the power
adapter.
