Page 9: Product Description
The unit is available in a variety of configurations to suit your electronic equipment’s environmental requirements. The self-contained, air cooled Liebert XDF is intended for installation in open areas. Installation in closed-in areas, such as in a closet, alcove or similar space, requires field-supplied ducting, an exter- nal booster fan and sufficient makeup air. -
Page 10: Operational Overview - Water/Glycol Cooled Model
Operational Overview - Water/Glycol Cooled Model The water/glycol cooled XDF model employs a single-stage cooling system rated at 14kW to supply cooling air to the rack-mounted equipment. A bank of fans circulates this cooling air through the elec- tronic equipment in the XDF (see Figure 1). An evaporator coil extracts heat from the circulating air. -

XDF C OMPONENTS Standard Components—Self-Contained, Air Cooled and Water/Glycol Cooled Models 3.1.1 Frame The self-contained, air cooled XDF is 82-1/4 inches (2089mm) tall; the water/glycol cooled unit, 79-3/4 (2026) tall. The self-contained, air cooled XDF has 36U (63 inches) of usable rack height. The water/glycol cooled XDF has 42U (73-1/2 inches) of usable rack height. -
Page 16: Environmental Control
3.1.5 Environmental Control The XDF supplies cooling air—68°F to 77°F (20-25°C)—to electronic equipment in the rack-mount equipment compartment. In normal operation, six fans at the right front corner of the XDF circulate cooling air through the equipment compartment. The laterally circulating air absorbs heat generated by the electronic equip- ment and transfers the heat to an evaporator coil at the right rear of the XDF. -

Page 27: Voltage Requirements
Voltage Requirements All XDF systems require two input power circuits. Each power cord is 10 feet (3m) long. For the full load amp requirements of each option, refer to 12.1 - Optional Power Systems or the component’s user manual. 4.5.1 Voltage Input Requirements The first input connection provides power—120V-1ph-60Hz, line-to-neutral—to the controls, evapora- tor fans and condenser fan. -
Page 28: Uninterruptible Power Supply-Optional
4.5.2 Uninterruptible Power Supply—Optional If your XDF is equipped with a UPS, it will require connection to a dedicated electrical circuit. Review the UPS’s user manual before connecting utility power to the unit. 4.5.3 MP Advanced Power Strips—Optional MP Advanced Power Strips are available in several power ranges. Consult Table 14 in 12.0 - Specifi- cations or the MP Advanced Power Strip user manual, SL-28015, for your model’s power require- ments. -
Page 29: Equipment Layout
Equipment Layout WARNING Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power before working within and/or installing equipment. Before installing or rearranging equipment, ensure the equipment and the UPS are switched off. Ensure that all electrical sources are disconnected. The lateral, circular flow of cooling air permits arranging equipment as required for stability if the XDF is filled or nearly filled with equipment. -

Page 35: Table 3 Ethylene Glycol Concentrations
Drycooler Loop System 5.3.1 Glycol Solutions The percentage of glycol to water must be determined by using the lowest design outdoor temperature in which the system is operating. Table 3 indicates the solution freeze point at several concentration levels of ethylene glycol. Propylene glycol concentrations should be 1% higher than the ethylene glycol table val- ues to find the freeze point. -
Page 36: Filling The Xdf With Coolant -Water Or Glycol
ILLING THE WITH Preparing the System for Filling It is important to remove any dirt, oil or metal filings that may contaminate the cooling system piping in order to prevent contamination of the coolant and fouling of the drycooler piping (IF USED). The system should be flushed thoroughly using a mild cleaning solution or high-quality water and then completely drained before charging with coolant. -
Page 37: Electrical Connections
LECTRICAL ONNECTIONS Power is supplied to the XDF through two factory-connected power cords (120V and 208V). For more information, refer to 4.5.1 - Voltage Input Requirements Additional electrical connections required for operation depend on the equipment installed in the XDF and remote communications desired.

Page 53: Backup Ventilation System
10.8 Backup Ventilation System The XDF is equipped with a backup ventilation system that circulates ambient air through the XDF should any component of the cooling system fail or if power is lost. The backup ventilation system begins operating only after the internal temperature exceeds the ambient external temperature. If powered by a UPS, evaporator fans circulate ambient air until the XDF returns to normal opera- tion. -
Page 54: Table 9 Troubleshooting
11.1 Periodic Maintenance The Liebert XDF requires very little maintenance. The XDF’s condenser coil must be inspected peri- odically to determine the necessary cleaning interval based on conditions at the installation site.
