Fine regulation of the operating pressures ṇ Caution Danger of damage to the plant. The following values should not be exceeded when you make changes to the plant settings: – Pump pressure maximum 1. 1 MPa (BW variant) – Maximum drinking water quantity 600 l/ h – The concentrate quantity should not fall below the value at the time of startup Note There is a time delay before the plant reacts to the changes done to the regulating valve. Hence do the settings at the pressure regulation valve in small steps and wait for the respective effect. (1) Drinking water flow has fallen from _______ l/h to _______ l/h  Read the current conductivity value on the display of the operating panel and compare it to the value at the time of start-up (see start-up report). If the drinking water conductivity has increased to _____μS/cm, then you need to rinse the membrane of the RO filter unit:  Reduce the drinking water output by opening the pressure regulation value to approx. 1 hour; then reset the nominal output by closing the pressure regulating valve. Note If rinsing the membrane does not result in lower conductivity values, then inform Kärcher Customer Service.
