However, up to now, no incompatibilitywith Vaillant appliances has been detected with properuse of the following products.• When using additives, follow the additive manufactur-er‘s instructions without exception.Vaillant accepts no liability for the compatibility of anyadditive or its effectiveness in the entire heating sys-tem.Additives for cleaning purposes(subsequent flushing required)- Fernox F3- Jenaqua 200- Jenaqua 300- Jenaqua 400- Sentinel X 300- Sentinel X 400Additives intended to remain permanently in the sys-tem- Fernox F1- Fernox F2- Jenaqua 100- Jenaqua 110- Sentinel X 100- Sentinel X 200Additives for frost protection intended to remain per-manently in the system- Fernox Antifreeze Alphi 11- Sentinel X 500• Inform the operator of the necessary measures incase you have used any of these additives.• Inform the operator of the required procedures forfrost protection.• Observe the applicable national regulations and tech-nical standards for the treatment of filling and top-upwater.Total heatingoutputTotal hardness at 20 l/kWfor the smallest boiler heatingsurface2)Total hardness at > 20 l/kW< 50 l/kW for the smallest boilerheating surface 2)Total hardness at > 50 l/kWfor the smallest boiler heatingsurface 2)kW mol/m 3 mol/m3 mol/m3< 50 No requirement or < 3 1) 2 0,02> 50 to ≤ 200 2 1,5 0,02> 200 to ≤ 600 1,5 0,02 0,02> 600 0,02 0,02 0,021) with systems equipped with wall-hung boiler and systems with electric heating elements2) of the specific system volume (nominal capacity in litres/heating output; in case of multiple boiler systems the lowest individualheating output should be used)These data only apply up to 3x the system volume for filling and top-up water. Once this triple system volume is exceeded, thewater will have to be treated exactly the same as in case of exceeding the limit values given in table 6.2 (softening, desalination,hardness stabilisation and desludging).Table 6.1 Guidelines for the heating water: Water hardnessProvided the national regulations and technical stand-ards do not specify any higher requirements, the follow-ing applies:• You must treat the heating water- if the total volume of filling and top-up water ex-ceeds thrice the nominal volume of the heating sys-tem over the service life of the systemor- if the limits given in the following tables are not ad-hered to.Heating waterqualities Unit Low-salt salineElectric conductivityat 25 °C μS/cm < 100 100-1500Appearance Free of sedimentary substancespH-value at 25 °C 8,2-10,01) 8,2-10,0 1)Oxygen mg/L < 0,1 < 0,021) With aluminium and aluminium alloys, the ph value range isrestricted from 6.5 to 8.5.Table 6.2 Guidelines for heating water: Salinitya Caution!Aluminium corrosion resulting in leakagescaused by unsuitable heating water!Unlike materials such as steel, cast iron or cop-per, aluminium is reactive to alkalised heatingwater (pH-value > 8,5) which results in signifi-cant corrosion.With aluminium, ensure that the pH value ofthe heating water ranges between 6.5 up to amaximum of 8.5.6 Start-up
