FAQ
Q: What is the difference between the Zurn 12-ZW1017XL and an ASSE 1070 point-of-use device?
A: The Zurn 12-ZW1017XL is an ASSE 1017 listed tempering mixing valve designed for installation at the hot water source to reduce distribution system temperature to 122°F or less. It should be used in conjunction with an ASSE 1070 point-of-use device at individual fixtures where end users may be exposed to hot water. The ZW1017XL should never be installed where end users can change its setting.
Q: What are the minimum requirements for proper operation of the Wilkins 12-ZW1017XL?
A: The valve requires a minimum flow rate of 0.5 gpm, a minimum approach temperature of 20°F between hot supply and outlet setting, and a maximum pressure differential of 15 psi between hot and cold inlets. Cold supply temperature should be 40-75°F and hot supply temperature should be 120-195°F maximum.
Q: Can the Wilkins 12-ZW1017XL be installed with a shut-off valve and thermometer?
A: Yes, it is recommended that the 12-ZW1017XL be installed with a shut-off valve and thermometer in the tempered water line to provide accurate and safe water mixing temperatures and facilitate maintenance and temperature verification.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.
