Tower Installation

These installation instructions are intended to help you prepare
before your tower arrives. If discrepancies exist between these
instructions and those shipped with the tower, the instructions
shipped with the tower will govern.
1. Prior to placement of the tower, confirm that the supporting platform is
level, and that the anchor bolt holes are correctly located in accordance
with Marley drawings.
2. Place tower (or bottom module of NC8411 through NC8414 models)
on your prepared supports, aligning anchor bolt holes with those in your
supporting steel. Make sure that the orientation agrees with your intended
piping arrangement. Attach tower to supporting steel with four
bolts and flat washers (by others). Position flat washers between the bolt
head and the tower basin flange.
3. NC8411 through NC8414 models only. Before setting top module in place
on bottom module, clean any debris from the underside of the top module fill,
skid and beams and from the top of the bottom module and remove shipping
cover from bottom of top module—replace fasteners at side of module to
prevent leaks. Place top module on the top peripheral bearing surface (factory-
installed gasket) of bottom module, aligning mating holes as it is set in place.
(Make sure that the orientation of the top module agrees with your intended
piping arrangement. Sections are 180° reversible with respect to each other.)
Attach top module to bottom module with fasteners provided—according to
"NC Field Installation Manual" Assembly Instructions.
If tower purchased is one fan cell only, ignore steps 4 through 8.
4. If collection basins are to be equalized by the use of Marley standard flumes,
unbolt the coverplate from the basin of the cell just installed. The coverplate
is located in the center of the basin side.
5. Unbolt temporary coverplate from the basin of the 2nd cell and set 2nd cell
(or bottom module of 2nd cell) in place. Align anchor bolt holes and flume
openings in basin sides.
6. Install flume according to Field Installation Manual instructions.
It is important that the cells be firmly anchored before the flume is
attached to the 2nd cell.
