2.4 Installation Considerations
The Liebert XDR is designed for attachment to the rear of computer cabinets in the data center. See
4.0 - Mechanical Considerations for details.
2.4.1 Room Preparation
The room should be well-insulated and must have a sealed vapor barrier. The vapor barrier in the
ceiling and walls can be a polyethylene film. Paint on concrete walls and floors should contain either
rubber or plastic.
Outside or fresh air should be kept to a minimum when temperature and humidity must be tightly
controlled. Outside air adds to the cooling, heating, dehumidifying and humidifying loads of the site.
Doors should be properly sealed to minimize leaks and should not contain ventilation grilles.
NOTE
The vapor barrier is the single most important requirement for maintaining environmental
control in the conditioned space.
