Manual Kärcher WT 4.000 Water Computer
Luigi Spezie 12-06-2022
The manual of the WT 4.000 control unit is unclear but already here other customers have already reported / confirmed it, such as Alessandro on 8-6-19, and I have some questions: 1) In the manual it says on page. 40: By pressing the function control key, the current status can be consulted at any time .... But which key is mentioned? 2) When you start to program, turn the frequency regulator to Res .... but meanwhile the left regulator goes to ON? A thousand thanks. Luigi
