About this guide
Optimum environment and site preparation
CAUTION:
Water quality that is out of spec may cause decreased cooling capacity or disruption in
service. The facility water supplied to the HPE Adaptive Rack Cooling System must meet the
guidelines stated in this manual. The HPE Adaptive Rack Cooling System warranty does not cover
damage caused by facility water that does not meet specifications.
To provide optimum performance with minimum maintenance, your site must meet environmental
requirements. The HPE Adaptive Rack Cooling System is intended to be installed in an indoor location
that is temperature controlled and relatively free of conductive contaminants.
To route water lines to your HPE Adaptive Rack Cooling System, use one of the following methods:
• Through an opening in the raised floor
• Through the top of the HPE Adaptive Rack Cooling System
Safety information
The HPE Adaptive Rack Cooling System is rated at a maximum facility pressure of 8 bar (116 PSI).
If valves are installed on the external pipe work that could potentially trap fluid inside the HPE Adaptive
Rack Cooling System, special precautions must be taken. To prevent severe plumbing failure due to
extreme pressure, use an expansion tank with a preinstalled safety valve in the plumbing circuit
connected to the unit.
WARNING:
This equipment must be installed in a restricted access area. The equipment is not to
be accessible to persons (including children) with reduced physical, sensory, or mental capabilities,
or a lack of experience and knowledge, unless they have been given supervision or instruction. Only
authorized technicians trained by Hewlett Packard Enterprise should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only subassembly- or
module-level repair. Because of the complexity of the individual boards and subassemblies, no one
should attempt to make repairs at the component level or to modify any printed wiring board.
Improper repairs can create a safety hazard.
