[. . . ] € Store chemicals away from the reach of children. € Ensure proper ventilation in the room while handling chemicals. € There must be a washing room closeby. – Keep an eye-washing liquid bottle handy. [. . . ] The plant may be put into operation only when set-up, installed and prepared for operation by skilled and authorized personnel. Monitoring elements Display media and active carbon filters – Display time Display of the operating panel Alternating display of: – Display for power failure: Spannungsausfall Uhr stellen !This display appears when the connection to the power supply is lost (for e. The plug has come out of the socket or there is power failure). Before Commissioning  Check the connection of the plant to the raw water source. σ Ensure uninterrupted flow of the generated drinking water into a tank or a suitable user-side facility. Note The drinking water must be able to flow out without any counter-pressure. The height difference must not be more than 3 m. Advance pressure unit Note If an advance pressure unit is required, then the same would be installed by the Kärcher service technician.

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. σ Check again the conductivity of the drinking water. Note If rinsing the membrane does not result in lower conductivity values, then inform Kärcher Customer Service. (3) Difference between pump and concentrate pressure has increased by more than ___ MPa Dosing table Dosing container Chemical Dosing per 10 l of dosing solution [ml] RM 852 SterPrechlorin- ilisation agent* ation Calcium hyprochlorite * Preflocking Antiscalant RM 5001 RM 5000 Hardness stabiliser RM 852 SterPostchlorin- ilisation agent* ation Calcium hyprochlorite * * These chemicals can be used as alternatives. 1 2 1 2 3 4 Concentrate regulation valve Pressure regulation valve Flow meter for drinking water Flow meter for concentrate Manometre for pump pressure Manometer for concentrate pressure  Read the quantity of drinking water at the flow meter for drinking water and compare it to the value when the plant was started (see start-up report). If the drinking water flow ahs fallen to ______ l/h, then do the following fine regulation:  Close the pressure regulation valve in a clock-wise direction until the flow meter for the drinking water has almost achieved the target value. σ Close the concentrate regulation valve slowly in the clock-wise direction until the required target value is reached for the two flow meters of the concentrate and the drinking water. Note Inform Kärcher Customer Service if this fine regulation does not lead to any changes to the drinking water flow. (2) Conductivity of drinking water has increased from _____μS/cm to _____μS/cm Note Small increases in the conductivity of drinking water does not affect the quality of the drinking water. σ Read the value on the manometer for the pump pressure and the concentrate pressure and determine the differential pressure. [. . . ] EN -4 15  Close the cover of the dosing station. σ Pull out the mixing rod from the dosing container until the stop and push it back into the container. 5 minutes until the chemicals are fully mixed. σ Deaerate the dosing pump according to the instructions in the chapter "Maintenance and Care".
