How It Works

When water temperature rises above 95ºF, the thermal actuator modulates the valve open. If the water exceeds 105ºF, the valve will go to full open position in order to discharge the over-heated water. When the water temperature returns to 95ºF, the thermal actuator modulates the valve to close.

Installation and Maintenance

Unit should be installed in a vertical orientation with flow direction downward. For full details, see Installation and Maintenance Manual.
