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 oor of one or more cells. An
appropriately-sized circular opening has been drilled to accept a 125#
ANSI B16.1 at-face ange connection.
