Low Profile Forced Draft Towers, Coolers and Condensers
Table 2 shows minimum “H” dimensions and gives “A” dimensions for the different unit sizes.
Extended Lifts
The recommended method for extended lifts is to use slings under the unit (Figures 3a and 3b). Safety slings, spreaders and skids
should be removed before nal positioning of the unit.
NOTE: Always use safety slings for extended lifts or where any safety hazard exists.
Applying Sealer Tape
If the unit was shipped with optional discharge attenuation or discharge hoods sealer tape must be applied prior installation of
the section. Once the unit has been set on the supporting steel and bolted in place, wipe the top anges to remove any dirt or
moisture. Place sealer tape over the mounting hole centerline on the side anges. Apply two strips of sealer tape, one partially
overlapping the other, on the end anges.
