ONE PIECE UNIT SHIPMENT
For lifting the unit, sling vertically. Position slings around
the unit, at the girth bands provided under the lower shell.
Use extreme care so as not to sling against, or on any
projecting brackets, pipes, fittings or any apparatus which
may be damaged under the weight of the unit. Do not
lift the complete unit by slinging the upper shell or
using the holes in the end sheets. See Fig. 3 - A.
After rigging the unit to its final position, remove the
skids before lowering the unit into position. Use shims
as necessary so that the unit sits squarely on the foundation.
While mounting bolts are not required, holes are
provided for bolts in each mounting foot for securing
the unit in areas known to experience earth tremors or
seismically active areas.
TWO PIECE UNIT SHIPMENT
All units are available as a two piece shipment for easy
of transportation and handling. Larger units (12F1 thru
14F3) are always shipped in two sections. Two piece

UNIT RIGGING
LD00937
shipments are built such that the rigger can set the two
sections together without disturbing the unit piping.
On multiple two-piece shipments, make
sure the upper and lower shells are
matched correctly. Match identification
numbers are stamped on each shell end
sheet. DO NOT MISMATCH THE UP-
PER AND LOWER SHELLS!
1. Installing the lower shell - Check the foundation and
set the lower shell in position in the manner described
for the complete assembly. Use proper jacks or rollers.
See Fig. 3 -B.
2. Installing the upper shell - Disconnect the skids from
the top shell assembly. Using slings around the top
shell at the girth bands, hoist the top shell assembly
into position above the bottom shell assembly. Use
tapered pins at two opposite corners of the top shell
to align the corner brackets as the top shell is lowered
onto the bottom shell assembly. Install the four
bolts at the corner brackets. See Fig. 3 - B.
