Chapter 2 Mechanical Installation

This chapter introduces the mechanical installation of the Liebert.PEX series air conditioner, including the
transportation, movement, unpacking, inspection, installation notes, system installation arrangement, installing indoor
unit, installing outdoor unit, piping for unit, lowering fan, removing fixtures and installation inspection.

2.1 Movement, Unpacking And Inspection

2.1.1 Transportation And Movement

Railroad transportation and shipping are the recommended means of transportation. If truck transportation is
unavoidable, choose roads that are less bumpy in order to protect the equipment.
The Liebert.PEX series air conditioner is heavy (see Table 2-1 for the weight). It is recommended to use mechanical
equipment such as an electric forklift to unload and move the equipment to the place closest to the installation site. If
an electric forklift is used, insert the tines of the forklift below the pallet, as shown in Figure 2-1. Align the tines with the
center of gravity to prevent the equipment from falling over.
When moving the indoor unit, keep the obliquity within the range from 75° to 105°, as shown in Figure 2-2.

2.1.2 Unpacking

Move the equipment to the place closest to the final installation site and then unpack it.
Follow the procedures below for unpacking:
