Do not let the rigging transfer any load to the cooling tower shell. Provide support to
the bottom of the cooling tower when rigging. Do not rig from the corners of the
optional base. Do not rig less than 8 inches from the corners.

Handle the fiberglass cooling tower shell section very carefully. Until installed and properly
supported, it is subject to handling damage. See Figure 2 for rigging information.

and fasten it securely with the stainless steel hardware provided.
3-5 Installing Piping
Make sure that all piping attached to the cooling tower is externally supported. Do not
support anything from the cooling tower shell.
The cooling tower and related fittings and connections are constructed of plastic materials
and are not designed to bear external weight.
Do not apply high torque to the fittings that are made up into the tower fittings. Use a backup
wrench when applying torque to the fittings.
Caution! Use appropriately rated
hoist to support equipment.
