Rigging
The complete standard chiller is shipped without skids. When optional skids are used it may be
necessary to remove the skids so riggers skates can be used under the unit end sheets to reduce
overall height.
Each unit has four lifting holes (two in each end) in the end sheets which must be used to lift the
unit.
Care should be taken at all times during rigging and handling of the chiller to avoid damage to the
unit and its external connections. Lift only using holes shown in Figure 4.
Never lift the unit with slings around motor/compressor assemblies or by means of eyebolts in the
tapped holes of the compressor motor assemblies. Do not turn a unit on its side for rigging. Do not rig
vertically.
The rigging and operating weights and overall dimensions are given in
a guide in determining the clearances required for rigging. Add 6 in. (15 cm) to overall height for
optional skidded unit.
The lengthwise rigging bar should be longer than the chiller tube length, and must have counter or
clevis adjustments to allow for center of gravity adjustments.
Chain spreaders should be used to avoid contact with drive motors or other chiller parts.
