Operating conditions
Permissible operating temperatures:
Cold water temperature ......................................................................... 5 – 25 °C / 41 – 77 °F
Recommended cold water temperature ............................................................... 15 °C / 59 °F
Hot water temperature .................................................................... 50 – 65 °C / 120 – 149 °F
Recommended hot water temperature ........................................................≤ 60 °C / ≤ 140 °F
Flow pressure:
min. flow pressure .................................................................................. 100 kPa / 15 psi / 1 bar
max. flow pressure ................................................................................. 500 kPa / 15 psi / 5 bar
Recommended flow pressure ..............................................................300 kPa / 44 psi / 3 bar
Water hardness:
Recommended water hardness: 6 – 7 °dH / 107 – 125 ppm CaCO
If the water is harder, a water softener is to be installed in the main cold water supply line.
35 041 970-90 0010 / 35 042 970-90 0010 must be installed with three-way diverter
