N.B.

Thermostatic cartridges are calibrated at the factory at 38°C ±1°C with a temperature differential of 50°C and 3 bar hot and cold water pressure. A new calibration is required in case of different values.

Dimensional features, technical data and optionals may change without notice as STSR carries on a constant activity of research, evolution and adaptation to the rules requirements of its products.
