Unit Rigging
One lifting chain is required for each lift-
ing point and each chain having a work-
ing load limit 40% of unit total weight.
The lifting chains traversing the evapora-
tor/condenser shells should remain 90°
+/- 10° from horizontal. A spreader bar
may be required to achieve the +/- 10°.
1. Attach rigging chains to an adequate lifting device.
2. Attach chains to the lifting holes at the corner
of each end sheet as shown on Figure 15 on
page 25.
3. If necessary to avoid contact with chiller compo-
nents install side spreader bars between the Evap-
orator and Condenser end sheet lifting chains.
4. The angle of the lifting chains traversing the en
sheet should not be less than 65° as shown on Fig-
ure 15 on page 25.
5. With an adequate lifting device lift the unit slight-
ly off the ground to determine adjustments neces-
sary to keep the unit level. Make adjustments as
necessary to level the unit.

The VSD is shipped with glycol in the
cooling system. The VSD coolant must
be changed to the inhibitor provided with
the shipped loose items prior to starting
the unit or a VSD over temperature fault
may occur.
1. Attach rigging chains from an adequate lifting de-
vice to the four lifting holes at the top of the VSD
as shown in Figure 16 on page 26.
2. Lift the VSD slightly off the ground to check for
