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
FXV, FXV3, CXVB, and CXVT units are factory-assembled to ensure uniform quality with
minimum field assembly. Single air intake models ship in two sections per cell (lower and
upper). Dual air intake models ship in four sections per cell (one lower and three upper:
each coil section ships separately) to minimize rigging and freight costs. Contact your local
BAC Representative for more information. For the dimensions and weights of a specific unit
or section, refer to the certified drawings.
Pre-Rigging Checks
When the unit is delivered to the jobsite, it should be checked thoroughly to ensure all
required items have been received and are free of any shipping damage prior to signing the
bill of lading.

Sheaves and Belts

Bearing Supports
Fan Motor(s)
Fan Guard(s)

attached to the side of the unit
marked “Contractor’s Installation
Instructions” indicates what
miscellaneous parts are included
with the shipment and where they
are packed.
WARNING:
Failure to use lifting
provisions can result in a dropped
load causing severe injury, death,
and/or property damage. Lifts
must be performed by qualified
riggers following BAC published
Rigging Instructions, and generally
accepted lifting practices. The
use of a supplemental safety
sling may also be required if the
lift circumstances warrant its
use, as determined by the rigging
contractor.
CAUTION:
Only personnel qualified
to do so should undertake
operation, maintenance and repair
of this equipment. Proper care,
procedures and tools must be used
in handling, lifting, installing,
operating, maintaining and
repairing this equipment to prevent
personal injury and/or property
damage.
