    1 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important safety instructions that should be followed during the installation and maintenance of the Liebert® DCD. Read this manual thoroughly before attempting to install or operate this unit. Only qualified personnel should move, install or service this equipment. Adhere to all warnings, cautions, notices and installation, operating and safety instructions on the unit and in this manual.
  • Page 6 All maintenance and repair jobs must be performed by properly trained and qualified personnel. All actions must be in accordance with regulations and the manufacturer’s instructions. Use only Vertiv-approved tools and parts for maintenance and repair. NOTICE Risk of improper power-supply connection. Can cause equipment damage and loss of warranty coverage.
  • Page 7 NOTICE Risk of piping-system corrosion and freezing fluids. Can cause leaks resulting in equipment and very expensive building damage. Cooling coils and piping systems are at high risk of freezing and premature corrosion. Fluids in these systems must contain the proper antifreeze and inhibitors to prevent freezing and premature coil and piping corrosion.

  • Page 13: General Product Information

    3 GENERAL PRODUCT INFORMATION 3.1 Product/System Description The Liebert® DCD™ is an air-water heat exchanger that is integrated into the rear door of a server rack. The DCD™ meets the requirements of the EN 60950 standard. The design allows installation on the back of a server cabinet and maintains access to the back of the servers while the chilled water connections remain stationary.

  • Page 14: Cooling Principle

    3.1.1 Cooling Principle The server fans force air heated by the rack equipment through the unit’s air-water heat exchanger where it is cooled. The air-side pressure-drop flow-rate dependency curve is shown in Figure B.7 on page 77. Vertiv | Liebert® DCD™ Installer/User Guide...

    4 PRE-INSTALLATION PREPARATION AND GUIDELINES The Liebert DCD attaches to the rear of a computer cabinet with side panels. See the dimensional-data drawings in the Submittal Drawings on page 83. NOTE: The cooling with Liebert DCD works only if a strict air separation exists between server cold air intake and server warm air outlet.

  • Page 20: Air-Flow Considerations

    DCD™ is mounted. 4.5 Water-supply Considerations For reliable function of the DCD™, chilled water must be available in an appropriate amount, of the required quality, and at the appropriate temperature and pressure. Vertiv | Liebert® DCD™ Installer/User Guide...

  • Page 21: Water Quality Requirements

    4.5.1 Water Quality Requirements To safeguard the maximum lifetime of air/water heat exchangers, the water used for chilling purposes must meet the VGB Chilled Water Guidelines (VGB-R 455 P). The chilled water used must be soft enough to prevent deposits, but it must not be too soft because that would lead to corrosion of the heat exchanger.
