PIPING INSTALLATION

NOTE: The most effective means for preventing deterioration from accelerated corrosion due to galvanic and stray current is the installation of dielectric fittings/unions. The installation of these fittings is the responsibility of the installing contractor.

1.Connect the cold water inlet and hot water outlet to the appropriate connections as shown; refer to the drawing for location and sizes.

2.Install in-line vacuum breaker, if supplied.

3.Install in-line pressure and temperature gauge, if supplied.

4.Install the combination temperature and pressure safety relief valve in the tapping provided. Note that this is required by law for safety considerations.
