Emerson XDF Manuel D’Utilisation

When deciding where to place your Liebert XDF, keep in mind these factors:

• electricity is required to operate the compressor (208V-3ph-60Hz) and the controls and evaporator 

fans (120V-1ph-60Hz)

• adequate ventilation and makeup air are necessary for proper equipment operation and protec-

tion

• service clearance must be provided
• the XDF must be on a level surface to ensure proper operation
• condensate must be drained, either by gravity-fed drain or optional condensate pump
• water/glycol cooled units require connection to a water or drycooler loop

Liebert’s self-contained, air cooled XDF is intended for installation in open areas. Field-supplied duct-

ing, an external booster fan and sufficient makeup air are required for installing a self-contained, air 

cooled model in closed-in areas, such as in a closet, alcove or similar space. Contact your local Liebert 

representative before installing the XDF in an area that might inhibit heat dissipation.
Note the dimensions of your XDF to determine the space required. The self-contained, air cooled XDF 

requires clearance of 36 in. (915mm) at the top, front, back and right side for equipment access and 

service (see Figure 17). The water/glycol XDF requires clearance of 36 in. (915mm) at the front, back 

and right side for equipment access and service; no top clearance is required.
