Fasteners and components provided by others that are to be at-
tached to the tower must be compatible with the cooling tower
materials—i.e. fasteners in a stainless steel cold water basin must
be stainless steel.

as prescribed on Marley drawings, do not support your pipe from
thetowerorinletconnection—supportitexternally.
Normally, one of the following four inlet arrangements is provided:
Standard distribution basin connections: These are circular openings–
two per cell–in the top deck of the tower near the air inlet face, provided
to accept standard 125# flat-face flanges. Remove the center section of
the inlet flume assembly to gain access to attach inlet fasteners. (Refer to
“NC Field Installation Manual” shipped with tower.)
Marley flow-control valve connections (option): Marley flow-control
valves–two per cell–are designed to 1–take the place of the standard
elbows normally required for inlet connection, and 2–provide means of
regulating flow to both sides of the tower. Remove the center inlet flume
assembly to gain access for attachment of valves. (Refer to “NC Field
Installation Manual” Assembly Instructions shipped with tower.) Valves
provide a vertical face for attachment of your standard 125# flange.
Side inlet connection (option): A pipe stub is provided in the casing
wall above the access door for connection to the external piping by means
of the rubber coupling provided.
Bottom inlet connection (option): An appropriately sized hole and bolt
circle–one per cell–is provided in the floor of the cold water basin. Bolt
circle is designed to accept a standard 125# flat-face flange.
