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 11 SHIPMENT
The chiller is split down the middle and shipped in
three assemblies:
• The condenser-side assembly.
• The evaporator-side assembly.
• The OptiView™ Control Center assembly.
• Miscellaneous shipped loose items.
The unit is first factory assembled, refrigerant piped,
wired and leak tested; then dismantled for shipment.
All wiring integral with compressor is left on it, and all
conduit is left on shell.
All openings on compressor and shell are closed and
3 to 7 PSIG (20 to 50 kPa) holding charge of dry ni-
trogen.
Refrigerant charges are shipped separately.
Arrangements with the local service of-
ce must be made to ensure refrigerant is
on-site when unit is ready to be charged.
Condenser Assembly
The lifting chains along the axis of the
condenser shell should not exceed 90°
+/- 10°. A spreader bar may be required
to achieve the +/- 10°.
One chain is required per each lifting
point.
Use lifting chains with working load
limit each at least 40% of the total shell
installed component weight.
1. Attach rigging chains to an adequate lifting device.
2. Attach chains to the lifting holes at the corner of
the end sheets as shown in Figure 18 on page 28.
3. If necessary to maintain minimum angles in-
stall side spreader between the condenser end
sheets to have the chains as shown in Figure 18
on page 28.
The angle of the lifting chains is critical
and damage to the unit may occur if the
rigging is not completed as described.
4. With an adequate lifting device lift the unit slight-
ly off the ground to check for center of gravity.
Make adjustments as necessary to level the unit.
