Assembly of the Coil Section to the
Pan/Fan
Secti
on
Before assembling the coil section to the pan/fan section, remove any loose parts shipped in the pan. On small centrifugal fan
units, the fan motor guard is normally shipped in the basin to avoid damage. It should be attached to the unit with the self-tapping
screws provided.
Wipe the flanges on the bottom of the coil section.
Check to see that the water distribution connection on
the coil section is in the correct position relative to the
pan-fan section (see certified print). Confirm that
sealer tape has been applied to the top of the pan-fan
section as shown in Figures 7 and 8.
Lower the coil section to within several inches of the
pan-fan section making sure the two sections do not
touch and the sealer tape is not disturbed. Place drift
pins (see Figure 13, Detail B) in at least 3 of the
corner mounting holes and gradually lower the coil
section into place using the drift pins to guide the
section down accurately onto the mating flange. On
5.4m and 7.3m long sections, drift pins should be
used midway along the sides as well.
Place fasteners in all four corner bolt holes. Then
continue to install the rest of the fasteners working
from the corners toward the center, using drift pins to
align the holes. A fastener must be installed in every
hole on the side flanges although none are required
on the end flanges. For units with two coil sections,
mount the first as described, and then follow the
same procedure for the second section.
