Piping materials

Do not use the following interconnecting piping materials in a closed water system:

•Oxidizing biocides

•Aluminum components

•Brass components with high levels of zinc

•Non-stainless steel iron components

•PVC

IMPORTANT: Even though some PVC grade piping materials are designed to handle the expected water pressure, the use of PVC materials should be reviewed and approved by the customer site engineers.

Power infrastructure installation

When determining the final location of the power connections, consider the following:

•Distance between the facility utilities and the location of the HP POD 20c
