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 pipework 

connecting the TankMixer

 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 

TankMixer

 thermostatic mixing valve, take the necessary precautions to 

ensure that such temperatures do not endanger people.

CAUTION:  

 In the case of highly aggresive water, arrangements must 

be made to treat the water before it enters the thermostatic mixing valve, 

in accordance with current legislation. Otherwise the thermostatic mixing 

valve may be damaged and will not operate correctly. 

SAFETY INSTRUCTION

CAUTION:  

 

All work must be preformed by qualified personnel trained
