Function

Scald Protection Three-Way 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 thermostatic

mixing valve and is ASSE 1070 listed.

The valve is complete with check valve at both hot and cold inlets.

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: 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.

Operating Principle A thermostatic mixing valve mixes hot and cold water in such a way as to maintain constant set temperature of 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.

Maintenance In service tests should be carried out regularly to monitor and record the performance of the valve. Deterioration in performance can indicate the need for servicing of the valve and/or water supply. If, during these tests, the mixed water temperature has changed significantly from the previous test results, record the change before re-adjusting the mixed water temperature.

Troubleshooting Under normal operating conditions the Caleffi 5213 series thermostatic mixing valve will provide a very high level of performance. However, in some circumstances, when our maintenance plan is not followed, the following problems may arise. Symptom Cause Corrective action Hot water at the cold taps a) Operation of the insert check valve is hindered; check valve is not sealing correctly. b) Check valves not fitted.
