3. 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. Attach top
module to bottom module with fasteners provided according to drawings
shipped with your fluid cooler.
4. Connect the recirculation piping with rubber coupling shipped with the
bottom module piping according to drawings shipped with you fluid
cooler.
5. Attach makeup water supply piping to appropriately-sized float valve
connection located in collection water basin side wall. Install the drain
and overflow according to drawings shipped with your fluid cooler. If you
wish to pipe overflow and drain water to a remote discharge point, make
those connections at this time also.
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.
6. Attach process fluid supply and return piping to the coil. Field piping
connection is an NPT male connection at the coil. A welded connection
requires removing the threaded portion of the coil.

Normally, one of the following two inlet arrangements is provided:
Bevel and groove distribution connection: This is a factory-installed,
galvanized pipe nipple, extending horizontally from the side of the tower.
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 ac-
cording to the manufacturer’s instructions.
Flanged distribution connection: The coil is fitted with a flat-face
flange connection that conforms to 125# ANSI B16.1 specifications. A
full faced gasket and appropriately sized bolts (by others) must be used
for proper distribution function.
