Regulator_1156F

Installation Instructions
1. The Watts Feed Water Pressure Regulator must be installed on the cold water supply line to the boiler. It may be installed in either vertical or horizontal position. Allow sufficient clearance to operate the fast fill and purge lever.
2. Install a shutoff valve upstream of the regulator. Local codes typically require the use of a backflow preventer in the system (Watts Model 9D). Consult local authorities for the type, installation and testing requirements. The backflow preventer must be installed upstream of the regulator.
3. Prior to installing the regulator, flush out the supply pipe to clear it of chips, scale, dirt, etc.
4. Install the Watts regulator in the supply line to the boiler with the arrow on the valve body pointing in the direction of flow to the boiler.
