MINIMUM COLD WATER TEMPERATURE: 1°C
Maximum Hot Water Temperature: 70°C*
Minimum Hot Water Supply Temperature: Blend water temperature plus 15°C
Maximum Cold Water Supply Temperature: Blend water temperature less 15°C
Thermostatic Control Range: approximately 25°C - 60°C
Optimum Thermostatic Control Range: 35°C - 50°C
*Note! For optimum performance reasons it is recommended that the maximum hot water temperature is limited
to 65°C.
Caution! During thermal disinfection the mixing valve can operate up to 85°C for short periods. Ensure safety
precautions are followed during discharge. Chemical disinfection agents e.g.chlorine/chloramines combined with
higher temperatures will affect the life of the product adversely and could detrimentally affect the thermostatic
performance.
