Leave this manual for the user.

CAUTION:  

 If the thermostatic mixing valve is not installed, commissioned 

and maintained properly, according to the instructions contained in this 

manual, it may not operate correctly and may endanger the user.

CAUTION:  

 Make sure that all the connecting pipework is water tight.

CAUTION:  

  When making the water connections, make sure that 

the pipwork connecting the MixCal™ thermostatic mixing valve is not 

mechanically overstressed. Over time this could cause breakages, with 

consequent water losses which, in turn, could cause harm to property and/

or people.

CAUTION:  

 Water temperatures higher than 100ºF (38ºC) can be 

dangerous. During the installation, commissioning and maintenance of 

the MixCal™ thermostatic mixing valve, take the necessary precautions to 

ensure that such temperatures do not endanger people.

CAUTION: 

To prevent any damage which will cause the electronic mixing 

valve to not operate correctly, treat highly aggressive water before entering 

the electronic mixing valve. Be sure water hardness is less than 10 grains.

CAUTION:  

 If installed in an ASSE 1017 application, check valves 

shall be used.
