connections. It blends hot and cold water to hold a field-adjustable outlet temperature of 90°F to 180°F. It is listed to ASSE 1017. It features a brass body. Rated to 125 psi. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 3\/4 inch lead free master tempering valve is designed for use in commercial and institutional applications, to mix hot and cold water to reduce high service water temperature to the building distribution piping system. It is designed for installation at the hot water source. It features a lead free brass body construction, a copper paraffin thermostat assembly and a lockable temperature adjustment for increased safety. Polysulfone internals resist excessive heat, liming and corrosion, and a single-seat design ensures tight shut off in the event of cold water supply loss. This valve also includes three-in-one checkstops to prevent cross flow, isolate valve for maintenance and integral screens to filter out debris. Listed to ASSE 1017 and IAPMO cUPC in compliance with CSA B125.3. The temperature range is 90 to 180 degrees F (32 to 82 degrees C) and the maximum pressure is 125 psi.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eParaffin-based thermostat to sense and adjust outlet temperature\u003c\/li\u003e\n\u003cli\u003eDirt and lime resistant poppet and seat design\u003c\/li\u003e\n\u003cli\u003e45 gallons per minute capacity at 45 psiD\u003c\/li\u003e\n\u003cli\u003eVandal resistant locking mechanism to secure temperature setting\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I use this at a lavatory — is it ASSE 1070 listed?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo. This valve is listed to ASSE 1017 only, which is a point-of-distribution standard: it tempers water leaving the water heater for the building distribution piping.

The maximum pressure rating is 150 psi (10.3 bar).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLead free brass construction\u003c\/li\u003e\n\u003cli\u003eThermal actuation technology for precise temperature control\u003c\/li\u003e\n\u003cli\u003eLocking mechanism secures temperature setting\u003c\/li\u003e\n\u003cli\u003eASSE 1070, ASSE 1069, ASSE 1017 and UPC listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I use this at a lavatory — is it ASSE 1070 listed?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. This valve is listed to ASSE 1070, the standard for point-of-use scald protection, so it is legal to install it serving a lavatory, sink or similar fixture. It is also listed to ASSE 1069 for multi-fixture point-of-use service. Because it additionally carries ASSE 1017, the same valve may be used at the water heater as a point-of-distribution tempering valve. Its outlet adjusts from 80°F to 120°F. Note ASSE 1070 does not cover showers — an in-shower device must be ASSE 1016 listed.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat temperature range does it deliver?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe outlet temperature is field-adjustable from 80°F to 120°F.
