3. Install rigging alignment pins on the cold water basin in the locations shown in
Figure
4
. Secure the alignment pins using the 1/2” hardware provided.
4. Position the lower section on the unit support and bolt into place.
5. Lower the hose connection on the pump discharge piping below the elevation of the
lower section before rigging the coil casing section.
6. Wipe moisture and dirt from the perimeter of the top flange on the lower section and
also from the perimeter of the top flange of the coil casing section.
7. Starting at one end, install flat butyl sealer tape (BAC part # 554000) supplied with
the unit, around the face of the flanges of the lower section in a continuous line. At
each corner, allow 1” overlap.
8. Lower the coil section until it is hovering 2-6” above the lower section.
9. Insert drift pin per
Figure 5
. Start at the corner hole and skip every 3 or 4
holes along the length of the unit. Repeat this process on the other side.
10. Lower the upper section the remaining distance using the alignment pins and drift
pins to align the coil casing section and lower section holes.
11. Fasten the hardware between the coil casing section and the lower section per
Figure
6
12. Ensure that moisture and dirt has been wiped from the perimeter of the top flange on
the coil casing section, which is now connected to the lower section.
13. On the coil casing section, install a layer of foam tape (BAC part # 270567) supplied
with the unit around the face of the flange over the centerline of the holes. Do not
leave any gaps.
14. Lower the mechanical section until it is hovering 2-6” above the coil casing section.
15. Insert drift pin per
Figure 5
. Start at the corner hole and skip every 3 or 4
holes along the length of the unit, inserting drift pins to align the mechanical section
and coil casing section holes. Repeat this process on the other side.
16. As illustrated in
Figure 8
, secure the mechanical section to the coil casing section
using the 5/16” self-tapping screws provided.
17. Position the hose connecting the sections of the pump discharge pipe and secure with
the hose clamps provided.
