scope:

Description

These devices shall be designed to supply only tempered water to the end user, and automatically compensate for pressure and/or temperature variations in water distribution systems. These devices shall have the capability to significantly reduce the outlet flow in the event of a cold water distribution system failure. The device shall be equipped with an adjustable means to limit the setting of the device towards the hot position. The device is intended to be the final temperature control.

Maximum Working Pressure

The maximum static pressure of the device shall be at least 125 psi (861.9 kPa).

Temperature Range

Inlet Temperature Range

The device shall be able to operate with cold water inlet temperatures between 39°F and 80°F (4°C and 27°C); and hot water inlet temperatures between 120°F and 180°F (49°C and 82°C).

Outlet Temperature Range.

The device shall be capable of supplying a minimum adjustable outlet water temperature range of 100 °F to 115 °F (37.8 °C to 46.1 °C), provided the hot water supply temperature is at least 20 °F (11.0 °C) greater than the outlet temperature setting. The maximum outlet temperature of the device shall be 120 °F (48.9 °C) when the temperature limiting means is adjusted.

Minimum Flow Rate

These devices are designed to function at a flow of 2.5 GPM (9.5 L/min), or the manufacturer's minimum flow rate, whichever is lower.

Connections

Pipe threads and other connections shall conform to local codes and applicable standards.
