Assembly of the Fan Section to the Coil/Basin
Section (3’, 4’, 8.5’, 10’ and 12’ Wide Models)
Before assembling the fan section to the coil/basin section, wipe the flanges on the bottom of the fan section. Check to see that the
motor access doors are in the correct position relative to the basin section (see certified print). Units are also provided with match
markings on each section (i.e. A1 of coil/basin section should match up with A1 of fan section). Place nuts and bolts in all four
corner bolt holes. Then continue to install the rest of the nuts and bolts working from the corners toward the center. Nuts and bolts
must be installed in every hole on the side flanges although none
are required on the end flanges. Drift pins are provided in rigging
box to assist with alignment.
