Introduction

Safety
Adequate precautions appropriate for the installation and location of these products should
be taken to safeguard the equipment and the premises from damage and the public from
possible injury.
The procedures listed in this manual must be thoroughly reviewed prior to
rigging and assembly. Read all warnings, cautions, and notes detailed in the margins.
When the fan speed of the unit is to be changed from the factory set speed, including the
use of a variable speed device, steps must be taken to avoid operating at or near the fan’s
“critical speed” which could result in fan failure and possible injury or damage. Consult
with your local BAC Representative on any such applications.
Shipping
BAC PT2 Cooling Towers are factory assembled to ensure uniform quality with minimum
field assembly. As standard, models ship in two sections per cell (lower and upper).
Optional shipment of three sections per cell and optional containerized shipments are
available. Contact your local BAC Representative for more information. For the dimensions
and weights of a specific unit or section, refer to the submittal drawings.

load causing severe injury, death,
and/or property damage. Lifts must
be performed by qualified riggers
following BAC published Rigging
Instructions, and generally accepted

supplemental safety sling may also
be required if the lift circumstances
warrant its use, as determined by
the rigging contractor.
