Installation

Note

Caution

It is important that the cells be firmly anchored and aligned before the flume is attached to the 2nd cell.

7.Repeat steps 2 and 3 for 2nd top section on AV63000 thru AV67000 models.

8.Repeat steps 4 through 7 for any remaining cells.

9.Attach your cold water supply piping to the cold water basin outlet connection in accordance with drawing instructions, and utilizing gaskets provided by Marley.

Do not support your pipe from the tower or outlet connection—support

it externally.

Normally, one of the following three outlet arrangements is provid- ed:

Cased face or air inlet face suction connection: This is a factory- installed, galvanized pipe nipple, extending horizontally from the side, or end of the cold water basin. It is both beveled for welding—and grooved for a mechanical coupling. If a weld connection is used, it is recommended that the weld area be protected against corrosion. Cold galvanizing is suggested, applied according to the manufacturer’s instructions.

Bottom outlet connection: This is a factory-installed, screened cir- cular opening in the cold water basin floor of one or more cells. An appropriately-sized circular opening has been drilled to accept a 125# ANSI B16.1 flat-face flange connection.

10. Attach makeup water supply piping to the float valve connection located at the air inlet face of the tower. If you wish to pipe overflow and drain water to a remote discharge point, make those connections at this time.

11. Attach your warm water return piping to the inlet connections of the tower.

Do not support your pipe from the tower or inlet connection—support

it externally.
