Liebert CR012 air conditioners are advanced precision air cooling units and therefore, these air conditioners must be
installed, preferably in a row of cabinets with high heat density and in a hot aisle and cold aisle arrangement.
Allocate space so that it is accessible for the qualified service personnel for repairs, servicing, and maintenance. For
the CR012 range, maintenance space must be allocated at the front and rear of the equipment.
A minimum space of 600mm must be assigned for maintenance in front of the system and at the rear of the system.
The allocated space is to facilitate regular maintenance tasks such as replacement of the filter, fans among others.
Figure 2-5 depicts the space allocated for servicing and maintenance.
