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 accor- dance with Marley drawings.

2.Place tower (or bottom module of AV6300 through AV6700) on your prepared supports, aligning anchor bolt holes with those in your sup- porting steel. Make sure that the orientation agrees with your intended piping arrangement. Attach tower to supporting steel with four 1⁄2" (13 mm) diameter bolts and flat washers (by others). Position flat washers between the bolt head and the tower basin flange.

Remove the sheet metal fill protector shields from the bottom of the top module before setting in place.

3.AV6300 through AV6700 models only. Remove shipping guards from bottom of top module (AV6500 thru AV6700). Clean any debris from the underside of the top module fill, skid and beams and from the top of the bottom module before hoisting into place.

Remove paper backing form sealer strips around top perimeter of

bottom module.

Place top module on the top peripheral bearing surface (factory- installed gasket) of bottom module, aligning mating holes as it is set in place. Attach top module to bottom module with fasteners provided— according to Field Installation Manual instructions.

If tower purchased is one cell only, ignore steps 4 through 8.

4.If collection basins are to be equalized by the use of Marley standard flumes, unbolt the temporary coverplate from the basin of the cell just installed. The coverplate is located on 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.
