  • Said level sensor constantly monitors the water level inside the reservoir and always indicates when the internal level reaches or leaves the "full tank” level. Therefore, whenever the device is restarted, such a reading is taken, and if it is detected that the reservoir is not full, the filling routine is started and, therefore, the pump is started and the valve that will allow the inlet to be opened. water in the reservoir. This action, however, promotes the filling of the reservoir by shots or loads of predetermined volumes, and when it is identified that the reservoir is completely empty, the first shot is preferably 300 ml, and once injected the determined volume the pump is turned off. If the level sensor reading indicates that the reservoir is not empty but not fully filled either, the additional shots will be approximately 100 ml per pump drive.
