Operation Flow Time Adjustment Examples To activate the product simply touch the ON symbol. The time flow is activated and the product will switch off after 8 seconds. The tap flow time is programmable on site. If required the factory programmed default flow time of 8 seconds can be adjusted to a value between 1 to 60 seconds. The tap has three adjustment levels for setting the flow time and a 4th level to activate or deactivate the duty flush. The duty flush must be turned off if a basin plug is provided. An indicator light (LED) on the underside of the sensor cap will guide you when adjusting the flowtime or activating or deactivating the duty flush. The following table and examples shows the number of adjustment steps in each adjustment level and how to recognize the adjusting level you are in. Adjustment Level 1 Levels Increments
