Liebert XDK User Manual

To achieve good air circulation, ensure that there is no packaging material or other equipment that 

could hinder or prevent air circulation in the area of the equipment, in the area of the heat exchanger, 

in the air inlet or in the air outlet.

After positioning, the XDK’s feet must be adjusted to make the cabinet vertical. When positioned the 

doors must close easily.

The Liebert XDK is shipped without the gas pressure springs for the front and rear automatic door 

openers installed. The springs should be installed according to separate instructions before the Lie-

bert XDK is connected and turned on.
After positioning, remove the transport lock screws at the sides of the recirculation air duct (see 

Figure 5).
The recirculation air duct may be pulled out to remove items that fall into the heat exchanger tray.

Risk of improper installation. Can cause equipment damage.
Before installing the unit, a number of points must be checked for safety and to ensure the 

correct function of the server cabinet. Take care when performing these checks  to ensure that 

the unit functions correctly.

Risk of improper installation. Can cause equipment damage.
The XDK must be installed on a level surface. For this reason, check the horizontal alignment 

with a spirit level prior to starting installation. The floor must be able to support a rack load 

of 307 lb/ft² (1500 kg/m²) (with installed equipment per XDK).
