Watts Regulator FR 500

Thermostatic Freeze Relief Kit

The FR500 Thermostatically measures the water tempera-

ture and will open at 35 °F, and close at 40ºF. This design

keeps the water from freezing in the backflow preventer, while

avoiding discharges based on the air temperature dropping to or

below freezing.

Installation:

The FR500 should be installed where freezing is of concern based on exposed

piping. When the valve is used in conjunction with a backflow preventer the FR500

should be located down stream of the assembly. Please note that additional

FR500s can be located upstream if desired.

The valve can be installed at any orientation to the centerline of the pipeline.

However, whenever possible the valve should be vertical down to horizontal.

This will allow the water to drain out of the FR500’s outlet and avoid the potential

of an ice dam impairing the function of the valve.

Care should be given to ensure that discharged water will be adequately piped

away from areas where slipping on ice could be a danger, like roadways and

pathways. Do not insulate the FR500 or install it where it will be exposed

to a heatsource.
