Mechanical Installation
Chapter 3: Mechanical Installation
Proper installation is important to achieve optimal performance and prolong the product life of the unit. In this
section, the mechanical installation will be discussed in detail to help the personnel handling the installation
process. Before proceeding with the mechanical installation, the following safety precautions need to be
considered.
• Prior to installation, ensure that the installation preparations have been read and implemented as per the
requirement, (refer to Section 2.3 ‘Environmental Requirements’). Check if any modications are made to
the piping, cabling, or ventilation facility before mounting the unit. Once the installation preparations are
taken into consideration, move on to the next step in the installation process, and eventually set up the
system.
• Liebert® CRV4 cooling units are designed for split-oor installation. The indoor unit must be installed on
the oor of the equipment room or computer room. The outdoor unit must be installed outdoor or on the
oor of the other room as per the building architecture.
• Follow the design drawings strictly when installing the unit. Reserve the space as per the maintenance
and serviceability instructions in the previous chapter on Installation Preparation. Refer manufacturer’s
engineering dimensions and drawings for details.
