Check the weight of the chiller by referring to the contract
specifications and then choose and use suitable wires and
shackles. To lift the chiller use the four holes provided at the
corners of the lower tube sheet. Note that the angle of the wires
should be 60° maximum, as shown in the figure below. Refer to
the specification drawings and exhibit LB.

Refer to the specification drawings and exhibit LC - Foundation. Set
the chiller on the foundation bolt positions.
