520___AC series: Adjustable three-way thermostatic mixing valve with mixed outlet temperature gauge,
angle body with inlet port check valves........................................................................................
Function
The Caleffi AngleMix ™ DL 520 series thermostatic mixing valve is
used in systems producing domestic hot water and easily mounts
to the top of water heaters. In addition to point of distribution
applications, the DL model is factory set for point of use applications,
limiting the maximum mixed outlet temperature to prevent scalding
water temperatures. The mixed temperature outlet is inline with the
hot water inlet, facilitating trouble-free connection and reducing
space required for installation. The AngleMix DL 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 closes its inlet ports tight, eliminating temperature creep in
recirculation loops. 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.
The AngleMix DL complies with both ASSE 1070/ASME A112.1070/
CSA B125.70 and ASSE 1017 and CSA B125.3. The DL model is factory
configured with an adjustment knob limiting mixed outlet temperature to
120 °F maximum. The device can be converted to ASSE 1017 function
by removing the rotation limiting screw. In addition, it is certified for
compliance with NSF/ANSI/CAN 372, low lead/lead free laws and use
according to U.S. and Canadian plumbing codes. AngleMix DL listed and
certified by ICC-ES, listing certificates detailed on page 2.

A thermostatic sensor (1) is fully immersed in the mixed water outlet passage (2) which, as it expands or contracts, continuously establishes the correct proportion of hot and cold water entering the valve.

Page 6: Installation Tip
Caleffi AngleMix DL 520_AC series thermostatic mixing valves are engineered for installation at either the point of distribution to regulate the temperature of the domestic hot water distributed within the downstream network, or at point of use for scald protection. The AngleMix DL 520_AC series mixing valve includes inlet tailpieces which have check valves, to meet the requirements of ASSE 1070. -
Page 7: Installation
Caleffi AngleMix DL 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 8: Check Valve
Per ASSE 1070 standard, check valves are required on the hot and cold water supply inlets. As a convenience for easier installations, the Caleffi 520 AngleMix DL thermostatic mixing valves include integral check valves in the hot and cold inlet tailpieces. If the check valves are removed from the tailpieces, ASSE 1070 compliance is voided and the product is not guaranteed to meet performance. - Page 9 Inser- Code tion Wt. (lb.)
