1.4 Liebert XDV—Vertical, Above-Cabinet Cooling Module
The Liebert XDV is installed on top of or above a rack enclosure. It is available with optional flexible
metal pipes with automatic shutoff with quick-connect couplings at the ends for easy connection to
the refrigerant distribution pipes. The Liebert XDV may be set up in either of two ways:
• The Liebert XDV can take hot air directly from an equipment enclosure, cool the air and dis-
charge it downward into the cold aisle.
OR
• The Liebert XDV can draw hot air from the room, cool the air and discharge the cool air down-
ward into the cold aisle.
