Function
The Caleffi TankMixer ™ 520_AX series kit combines a three-way
thermostatic mixing valve with a cold water tee and flexible pipe for
easy installation directly on a typical gas-fired water heater and other
water heaters that now comply with the National Appliance Energy
Conservation Act (NAECA). The TankMixer ™ maintains the desired
output temperature of the mixed water supplied at a constant set
value compensating for both temperature and pressure fluctuations
of the incoming hot and cold water. The mixing valve also features a
thermal shut-off function that operates in the event of a cold water
supply failure at the inlet. Also available as body only, for a wide
variety of separately-sourced end connections, the angle style body
design offers improved fluid dynamics for better performance and
reduces installation labor and materials, eliminating a piping elbow
in typical installations.

SAFETY INSTRUCTION This safety alert symbol will be used in this manual to draw attention to safety related instructions. When used, the safety 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 preformed by qualified personnel trained in the proper application, installation, and maintenance of systems in accordance with all applicable codes and ordinances. -
Page 3: Operating Principle
Operating principle The thermostatic mixing valve mixes the hot and cold water at the inlets to maintain constant mixed water at the desired set temperature. The TankMixer™ 520 series point of distribution mixing valve is an angled configuration combined with a flexible hose and cold water tee for easy installation to most water heaters for direct mounting to the universal ¾”... - Page 4 They should not be used where ASSE 1070 devices are required. Wherever a scald protection feature is required, Caleffi 5213 series high performance mixing valves need to be installed. For safety reasons, it is advisable to limit the maximum mixed water temperature to 120°F when anti-scald devices are not used at each fixture.

Page 5: Installation
Caleffi TankMixer ™ 520 series thermostatic mixing valves can be installed in any position, either vertical or horizontal, or upside down. The following are shown on the thermostatic mixing valve body: - Hot water inlet, color red and marked “HOT”. - Page 6 Commissioning The Caleffi TankMixer ™ 520 series thermostatic mixing valve must be commissioned in accordance with current standards by qualified personnel using temperature measuring equipment. Caleffi 520510AX, 520516AX and 5210519AX with integral outlet port temperature gauge provide a time-saving temperature setting process to get close to the desired temperature.
