The flushing system can be activated without the need for contact thanks to the infrared sensor integrated into the release button. Compatible with most cisterns, the flushing system has been designed to offer a quick and easy installation at home and in public spaces. The system transforms traditional push-button water tanks into contactless tanks in a very short time and without the need to perform any work. Powered by 4 AA batteries (included), it does not require any electrical connection and guarantees approximately 50,000 discharges. Thanks to contactless technology, the flushing is activated automatically when the infrared sensor detects the presence, thus preventing the transmission of viruses and bacteria and contributing to greater hygiene in the bathroom. The infrared sensor allows you to activate the desired type of discharge - partial or complete (3 or 6 litres) - based on the movement of the hand. If the hand is held fixed over the sensor, a partial discharge is released, while if the hand makes a movement, a total discharge is released. If necessary, the flushing can always be activated in the traditional way by pressing the release button.
