2.4 Movement, Unpacking And Inspection
2.4.1 Transportation And Movement
Railroad transportation and shipping are the recommended means of transportation. If truck transportation is
unavoidable, choose roads that are less bumpy to protect the equipment.
The CRV+ air cooled AC unit is heavy (see Table 3-1 for the weight). It is recommended to use mechanical
handbarrow such as an electric forklift to unload and move the equipment to the place closest to the installation site.
If a forklift is used, insert the tines of the forklift below the pallet, as shown in Figure 2-2. Align the tines with the
center of gravity to prevent the equipment from falling over.
