To lift the compressor, use lifting points on compres-
sor frame to attach the lifting device, see Table 3-2 and
Figure 3-1 to 3-6. There are a few points to consider prior
to moving it:
• Ensure that the weight is evenly distributed amongst
the lifting device (i.e. lifting chains and spreader bar)
prior to lifting.
• Ensure that the lifting device is not obstructed by
any parts of the compressor to prevent damage to
components.
• Use additional personnel as needed to spot and aid in
maneuvering the compressor.
• Ensure there is plenty of space to maneuver the com-
pressor, and a clear path to its location.
