SAFETY SLINGS

Extended Lifts
Important: The lifting devices and “U” bolts should be used for final positioning only and for lifting where no danger
e
xists. If they are used for extended lifts, safety slings should be provided under the sections.
Safety slings and skids must be removed before final positioning of the unit.
The preferred method for extended lifts is to use slings under the unit, as shown in Figure 7 below. Spreader bars should always be
used between the cables at the top of the section to prevent damage to the upper flanges or fan cylinders.
Assembly of the Coil/Fan Section to the Basin
Before securing the upper section to the bottom section, remove any loose
parts shipped in the basin.
Wipe the flanges on the bottom of the upper section. Check to see that the
water distribution connection on the top section is in the correct position
relative to the bottom section (see unit certified drawing). Units are also
provided with match markings on each section (i.e. A1 of bottom section
should match up with A1 of top section).
Lower the upper section to within several inches of the bottom section making
sure the two sections do not touch and the sealer tape is not disturbed.
Fasten all four corners. Make use of drift pins to simplify the fastening
process, for further instructions on the use of drift pins, see page 10.
Install the remaining fasteners, working from the corners towards the center.
Fasteners must be installed in every hole in the side flanges. No fasteners
are required on the end flanges.
