IMPORTANT SAFETY GUIDELINES SAVE THESE INSTRUCTIONS ! CAUTION Risk of piping and component rupture. May cause injury or equipment damage. Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of piping. Do not close valves without follow recommended procedures for repair, maintenance and replacement of components. Installing pressure relief valves in field piping that may become isolated by service valves.

General product information 2.0 GENERAL PRODUCT INFORMATION The Liebert XDCF™ is a self-contained module designed to cool Egenera’s BladeFrame EX cabinets and equipment without exhausting heat into the room. Liebert XDCF modules consist of a sheet-metal frame, coil and filter dryer. It has no moving parts and needs no electricity.
General product information 2.4 Product/System Description Upper and lower modules may be mounted on the rear of the Egenera BladeFrame. Each module, when attached to a fully loaded BladeFrame EX rack, has a nominal cooling capacity of 10kW (2.8 tons; 34,000 BTUh). Performance is based on: • Entering fluid temperature—55°F (12.8°C) and • Dew point—50°F (10°C) or lower. The complete system consists of Liebert XDCF modules, piping and Liebert XDP or Liebert XDC (see Figure 3 below.
General product information 2.6 Unpacking the Liebert XDCF The unit is shipped in a protective package. Do not remove the packaging from the Liebert XDCF before it is at the installation location. • When unpacking and handling the Liebert XDCF, care should be taken to prevent damaging the coils. • Remove outer packaging when ready to install the Liebert XDCF. • Do not use unit piping to lift or move the Liebert XDCF. 2.6.1 Recyclable Packaging R All material used to package this unit is recyclable.
Mechanical Considerations 3.0 MECHANICAL CONSIDERATIONS The Liebert XDCF is engineered to fit on the rear of the Egenera BladeFrame enclosure. Figure 5, below, illustrates the unit’s dimensions and the location of pipes. Figure 6 shows the attachment positions of each module.
Installation 4.0 INSTALLATION 4.1 References This document must be used together with site-specific documentation and documentation for other parts of the system. 4.2 Installation Considerations Liebert XDCF modules must be securely mounted to the rear of the Egenera BladeFrame cabinet. No cutting or drilling is required to attach the modules; all mounting holes, slots and pins required are fabricated at the factory.
Installation 4.3 Mounting Lower Liebert XDCF Module The lower Liebert XDCF module attaches to the Egenera BladeFrame cabinet with a mounting bracket, four bolts and a metal stud. Before the Liebert XDCF is mounted, the mounting bracket and a two-piece deflector panel must be attached to its top surface and insulation must be applied to the left side. 4.3.1 Preparing the Lower Module for Attachment 1. Position the mounting bracket over the two mounting holes.
Installation 4.3.2 Attaching Lower Liebert XDCF Module Liebert XDCF modules mount on the rear of the Egenera BladeFrame cabinet, near the power modules. The cabinet and Liebert XDCF have prefabricated mounting holes and studs to ease mounting. 1. Set the lower Liebert XDCF module on the left side of the ledge on the rear of the Egenera BladeFrame cabinet. Make sure the positioning stud on the bottom of the Liebert XDCF fits into the locator hole on the ledge as shown in Figure 8.
Installation Attaching Liebert XD Flex Pipe Support Panel Use of only the lower Liebert XDCF module requires attaching a Liebert XD Flex Pipe support panel and three pipe retainers. The retainers keep the refrigerant pipes behind the Egenera cabinet. If an upper Liebert XDCF module will be used, the Liebert XD Flex Pipe retainers will be attached to the upper module. To attach the Liebert XD Flex Pipe support panel: 1.
Installation 4.4 Attaching Upper Liebert XDCF Module The upper Liebert XDCF module attaches to the Egenera BladeFrame cabinet with a mounting angle and four bolts. Before the Liebert XDCF is mounted, the mounting angle and a two-piece deflector panel must be attached to the bottom of the Liebert XDCF and insulation must be applied to the left side. 4.4.1 Preparing the Upper Module for Attachment 1. Position the mounting angle over the two mounting holes.
Installation 4.4.2 Attaching Upper Liebert XDCF Module The upper Liebert XDCF module mounts on the rear of the Egenera BladeFrame cabinet, above the lower Liebert XDCF module. The cabinet and Liebert XDCF have prefabricated mounting holes and studs to ease mounting. 1. Attach the mounting angle to the bottom of the Egenera BladeFrame cabinet with a 10-32 nut that fits onto the stud on the back of the cabinet, see Figure 6). 2.
Piping Connections and Piping Access Points 5.0 PIPING CONNECTIONS AND PIPING ACCESS POINTS Refer to site specific drawings for general locations of the piping connections. For Liebert XDCF connection locations, refer also to Figure 12. 5.
Piping Connections and Piping Access Points 5.3 Recommended Piping Size Connect the main pipes between the Liebert XDCF branch piping and the Liebert XDP or Liebert XDC according to Table 1. Elbows and restrictions must be minimized to get good fluid flow. Connect the branch pipes between the main piping and the Liebert XDCF according to Table 1.
Piping Connections and Piping Access Points Figure 13 Liebert XD prefabricated piping assembly Return Main Service Valve, typical (all ports) Supply Main Threaded Cap (Typical) 5. Thread the return couplers together, the larger of the two couplers (Liebert XD Flex Pipe and return main). 6. Use one of the adjustable wrenches to hold the fixed side of the female coupler on the Liebert XDCF stationary. With the other adjustable wrench, tighten the collar onto the coupler.

Place the protective dust cap and plug back onto both ends of the coupler on the Liebert XDCF and the port pipe. Figure 17 Piping mains without Liebert XDCF and Liebert XD Flex Pipe 8. Repeat Steps 5 through 7 for the return coupler (larger coupler). 9. Carefully lay the Liebert XD Flex Pipe aside. NOTICE Do not fold or bend Liebert XD Flex Pipe.
Checklist for Proper Installation 6.0 CHECKLIST FOR PROPER INSTALLATION ___ 1. Liebert XDCF modules are securely attached to the cabinet. ___ 2. Piping from Liebert XDP or Liebert XDC, with isolation valves, properly connected to each Liebert XDCF module. ___ 3. Flex piping connections to prefabricated header assembly are secure and according to specifications. ___ 4. Check the R-134a refrigerant charge. ___ 5. System checked for leakage. ___ 6.
Maintenance 7.0 MAINTENANCE Minimal maintenance is required to keep the Liebert XDCF operating at optimal levels. The unit should be cleaned and checked for damage. Suggested maintenance includes: • Cooling fins—Clean any dust and debris from the cooling fins, taking care not to bend them. 7.
