5.1 Preparation for Installation
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.
5.2 Positioning the XDK
After positioning, the XDK’s feet must be adjusted to make the cabinet vertical. When positioned the
doors must close easily.
5.2.1 Remove Recirculation Air Duct Transport Lock
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.
