center of gravity. Make adjustments as necessary
to level the VSD.
3. Lift the VSD and remove all packing material, for
VSD weight refer to Table 10 on page 26.
4. Carefully lower the VSD on to the supports on the
condenser.
5. Fasten the VSD to the condenser and to the motor
terminal box duct. Remove the rigging chains.
Use lifting chains with working load limit
each 35% of total VSD weight.

FORM 10 SHIPMENT
The chiller is shipped in two assemblies:
• The chiller unit (less the VSD).
• The VSD.
• Miscellaneous shipped loose items.
The complete unit is factory leak-tested, evacuated,
and shipped charged with refrigerant.
The unit is first factory assembled, refrigerant piped,
wired and leak tested; then dismantled for shipment.
Evaporator/condenser is not skidded. All wiring inte-
gral with compressor is left on it, and all conduit is left
on shell.
Unit Rigging
One lifting chain is required for each lift-
ing point and each chain having a work-
ing load limit 30% of unit total weight or
heat exchanger being lifted.
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 14 on
page 24.
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 14 on page 24.
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 17 on page 27.
2. Lift the VSD slightly off the ground to check for
center of gravity. Make adjustments as necessary
to level the VSD.
