Existing Facility Excavation
Excavation is the same as in new construction. However, it will be necessary to break
out a trench 6"-8" wide by 12" deep to run the PVC chase.
Installation
1. For best balance of lift / containment assembly while lowering into excavation,
sling using the shipping straps provided. See Figure 3. DO NOT remove or
loosen any of the bearing assembly bolts at this time.
Note: The assembly weighs approximately 2300 lbs.

Using a chain hoist and tripod, fork lift, crane, etc. for lifting; lower the lift /
containment assembly in the excavation being sure the PVC inlet hole is toward
the power unit, until the top of the assembly is 1/8" to 1/4" above finished floor
level and aligned with the previously determined center lines. Refer to Figures 1
and 3.
3.
Remove the outer two bolts from each end of the center cover plate and replace
with 1/2-13 x 18 threaded rods. Attach two 6 x 6 timbers using ½-13 nuts and
washers, to support the lift / containment assembly on the existing floor or forms.
Remove the shipping straps and replace the bolts. Torque the bolts to 60 ft-lbs.
Bend concrete tie anchors out 90 degrees and down 45 degrees. Refer to
