Multi-Cell Unit Installation
Refer to the submittal unit print for the proper orientation of each cell. All multi-cell units
have the cell number and “face” stenciled on the outer basin wall of each lower section,
as well as match marks to show how the cells are to be mated. Multi-cell unit installations
may use flume boxes to equalize the water level in the basin of each cell. Follow directions
in “Flume Box Installation” below for detail on their installation.
Multi-Cell Unit Assembly
1. Attach the first cell’s lower section to the support and then fasten the first cell’s upper
section to the first cell’s secured bottom section. For units shipped in two sections per
cell, follow the instructions on
. For units shipped in three sections per cell,
2. Each subsequent cell should be assembled adjacent to its final location, and then
properly positioned next to the previous cell. Ensure spacing between the cells at the
bottom flange is 3” on Face A-B, 5” on Face C-C.
3. PCC quad cell units come with air bypass panel windows on Face C as shown in
Figure 11
. These windows facilitate removal of the inner most lift shackle after the
final cell is installed. The window panels FAB are shipped loose inside the cold water
basins and should be installed using the supplied flat butyl sealer tape (BAC part #
554000) and 5/16” self-tapping screws after the final cell is in place and the lift
shackles are removed.
4. Some PFi units come furnished with a flume box. If they do, use the flume box
assembly procedure outlined on
to connect the basins of multi-cell units.
NOTE:
On quad cell installations,
it is suggested that the cells
subsequent to the first cell have the
upper and lower sections assembled
on the support foundation adjacent
to the final mounting locations. This
will allow space for securing the
upper and lower sections of each
cell. Move the subsequent cell(s) to
their final position using the lifting
devices on the casing.
