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

• Distance between possible UPS or generator locations and the HP POD 20c

• Requirements for routing electrical feeders (underground or overhead)

The facility power connection must be installed in compliance with local electrical codes and regulations. HP

reference electrical installation design is based on a maximum distance of 15.2 m (50 ft) or a line of sight

between the disconnect and the HP POD 20c.

Site electrical system

To ensure a complete and safe integration of the HP POD solution with your facility, HP requires that you

complete the following actions for the installed electrical system prior to the installation of the HP POD

solution:

• Short circuit analysis

• Arc flash study

• Circuit breaker coordination study
