1. Figures 7a, 7b, and 7c show the proper rigging of sections
for units that ship in three sections.
2. Remove any motors or accessories shipped in the lower
section.
3. Install rigging alignment pins on the water basin in the loca-
tions 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
(Part#:
BAC554000)
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. When necessary, insert drift pin per Figure 5 on page 6. 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 pe-
rimeter 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
(Part#:
BAC270567)
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. When necessary, 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.
