Assembly of the Heat Transfer Casing (Top) Section to the Basin & Fan (Bottom) Section
Before assembling the heat transfer casing (top) section to the cold water basin and fan (bottom) section, remove any loose parts shipped
in the basin.
Wipe the flanges on the bottom of the casing section. Check to see that the water distribution connection on the casing section is in the
correct position relative to the basin and fan section (see certified print). Confirm that sealer tape has been applied to the top of the basin
and fan section as shown in
Figures 5
and
6
.
Lower the casing section to within several inches of the basin and fan section, making sure the two sections do not touch and the sealer
tape is not disturbed. Place drift pins (see
Figure 12
and
13
) in at least three (3) of the corner mounting holes and gradually lower the
casing section into place using the drift pins to guide the section down accurately onto the mating flange. On long sections, 18 feet and
longer, drift pins should be used midway along the sides as well.
Place fasteners in all four (4) 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 casing sections, mount the first as described, and then follow the same procedure for the second section.
