5213 Series
INSTALLATION AND COMMISSIONING MANUAL
Function
Thermostatic mixing valves are used in applications where the user
must be protected from the danger of scalding caused by hot water.
The Caleffi 5213 series provides water at a safe and usable
temperature in situations where the control of the temperature of the
water discharging from a terminal fitting is of the utmost importance,
i.e. within hospitals, schools, nursing homes, etc. The valve is
designed to prevent the flow of water discharging from the mixed
water outlet in the event of the failure of hot or cold supply. The Caleffi
5213 series is a high performance combination thermostatic and
pressure balanced mixing valve and is ASSE 1070 listed (temperature
can not exceed 120°F). The valve is complete with check valve at
both hot and cold inlets. Certified to ASSE 1070 and Low Lead Plumbing
Law by ICC-ES.

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.
WARNING: This product can expose you to chemicals including lead, which is known to the
State of California to cause cancer and birth defects or other reproductive harm. For more
information go to www.P65Warnings.ca.gov.
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.
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 thermostatic mixing valve 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: 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.

Operating principle
HOT
COLD
MIXED
connections
The thermostatic mixing valve mixes hot and cold water in such a way as to maintain constant set
temperature of the the mixed water at the outlet. A thermostatic element is fully immersed into the
mixed water. This element then contracts or expands causing movement of the piston, closing
either the hot or cold inlets, regulating the flow rates entering the valve. If there are variations of
temperature or pressure at the inlets, the internal element automatically reacts to restore the original
temperature setting. In the event of a failure of either the hot or cold supply, the piston will shut off,
stopping water discharging from the mixed water outlet.
Thermal shutoff
In the event of a failure of either the hot or cold supply, the piston will shut off, stopping water
discharging from the mixed water outlet. The Caleffi 5213 series thermostatic mixing requires a
minimum temperature differential from hot inlet to mixed water outlet of 18°F (10°C) to ensure the
correct operation of the thermal shutoff feature.
