Page 7: Installation Considerations
Installation Installation Considerations The XDO module is to be securely mounted to the overhead building structure. It is typically hung 18- 24" (457-610mm) above the heat-dissipating equipment. A suspended ceiling, if one exists, should be at the same level as the top of the XDO. If the suspended ceiling has open grates, it may be the same level as the bottom of the XDO. -
Page 8: General Product Information
Product/System Description Introduction The Liebert XDO is an overhead cooling system designed for installation above heat-dissipating equipment. A fan draws hot air exhausted from the equipment through two cooling coils and dis- charges cool air back down to the equipment (see Figure 3). The system consists of XDO modules, XDP/XDC coolant distribution units, power and signal cabling and interconnecting piping (see Figure 4). -
Page 9: Equipment Inspection
Upon arrival of the unit, and before unpacking, verify that the labeled equipment matches the Bill of Lading. Carefully inspect all items for either visible or concealed damage. Damage should be immedi- ately reported to the carrier and a damage claim filed with a copy sent to Liebert Corporation or to your sales representative. -
Page 10: Unit Handling
• If using a fork lift or pallet jack, ensure that the fork tine length is suitable to safely move the packaged unit. • It is recommended by Liebert Corporation that the unit remain in the protective packaging until located at the installation site. -

Mechanical Considerations ECHANICAL ONSIDERATIONS WARNING Be sure to securely anchor the top ends of the suspension rods. Make sure all nuts are tight. Locating in Ceiling, Spacing The distances between the XDO modules are determined by the heat density to be cooled. Refer to site-specific drawings for exact spacing. -
Page 15: System Connection Configuration
Mechanical Considerations System Connection Configuration If possible, connect the XDO modules to XDPs or XDCs in an interlaced configuration (see Figure 10). Interlacing the connection piping will keep half the XDP/XDC units operating and main- tain even cooling in the conditioned space should one of the XDP or XDC units fail. However, in a system with just one XDP or XDC, connect XDO modules in a non-interlaced configura- tion (see Figure 11). -
