Two Piece Section Assembly
1. Remove any accessories shipped in the cold water basin.
2. Position the lower section on the unit supports and bolt in place.
3. Wipe any moisture and dirt from the perimeter mating flanges of the lower
section.
4. Install foam seal tape (BAC part # 270175) supplied with the unit, as
illustrated in Figure 3, on the mating flanges of the lower section in a
continuous line. At each corner, allow 1” overlap.
5. Complete assembly using the external bolt holes as guides for alignment:
– Before lowering the upper section onto the lower section, be sure to line
up the bolt holes using drift pins as illustrated in Figure 5, no fewer than
one hole at each edge. Guide the upper section onto the lower section
starting with a bolt hole at one corner and following down the flange.
– Match marks must line up as shown in Figure 3.
– Secure the upper section in place as shown in Figure 4 to ensure leak-
free operation.
