CAUTION: 

All work must be performed by qualified personnel trained in the 

proper application, installation, and maintenance of systems in accordance 

with all applicable codes and ordinances.

SAFETY INSTRUCTION

This safety alert symbol will be used in this manual to draw attention to safety related instructions. 

When used, the safety alert symbol means 

ATTENTION! BECOME ALERT! YOUR SAFETY IS 

INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY 

HAZARD.

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 mixing 

valve connecting pipework is not mechanically over-stressed. 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 100°F can be dangerous. During 

the installation, commissioning and maintenance of the thermostatic mixing 

valve, take the necessary precautions to ensure that such temperatures do 

not endanger people.

CAUTION:

 In the case of highly aggressive water, arrangements must be made 

to treat the water before it enters the thermostatic mixing valve, in accordance 

with current legislation. Otherwise the mixing valve may be damaged and will 

not operate correctly.
