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

CAUTION: 

 

 

If installed in an ASSE 1017 application, check valves shall be 

used.
