1. Warnings and Cautions
Safety Precautions
•: Failure to use appropriate lifting equipment 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.
•: To prevent bodily injury or property damage, only qualified personnel qualified should
undertake the installation, 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
•: Equipment damage may occur if water, snow, ice, or debris has collected in the basin or
elsewhere in the unit. Such accumulations will add substantially to the equipment’s lifting weight placing equipment at
risk of damage that could result in injury. Before an actual lift is undertaken, ensure no water, snow, ice, or debris has
collected in the basin or elsewhere in the unit.
•: Equipment damage may occur if the unit is not properly anchored before operation begins.
Equipment damage could result in death or serious injury. Ensure unit is properly anchored before operation beings.
•: ENDURADRIVE®Fan System motors can induce voltage and current in the motor leads by
rotating the motor shaft, even when the motor is completely disconnected from the power source, which can lead to
severe bodily injury or death from electrical shock. Mechanically lock or tie down the fan until all wiring has been
completed and before servicing the drive system, or when performing any motor maintenance procedure.
•: Magnetic and electromagnetic fields in the vicinity of current carrying conductors and
ENDURADRIVE®Fan System motors can result in a serious health hazard to persons with cardiac pacemakers,
metal implants, and hearing aids. To avoid risk, stay away from the area surrounding the ENDURADRIVE®Fan
System motor.
•: The ENDURADRIVE®Fan System variable frequency drive may apply hazardous voltages
to the motor leads after power to the controller has been turned off. To avoid the risk of severe bodily injury or death
from electrocution, verify that the controller is incapable of delivering hazardous voltages and that the voltage at the
motor leads is zero before servicing the drive system, or when performing any motor maintenance procedure.

FXV3/CXVT Rigging & Assembly Instructions –Warnings and Cautions Page | 6
Equipment Precautions
•Each unit must be located and positioned to prevent the introduction of discharge air into the ventilation systems of
the building on which the unit is located and of adjacent buildings.
•For weight information, refer to the submittal drawing package.
•All single-cell and multi-cell units must be rigged one section at a time.
•For weight information, refer to the submittal drawing package. Any motors or accessories shipped in the cold water
basin must be removed prior to installing the upper (mechanical and coil casing) section.
•Failure to level the coil module for rigging will prevent proper engagement of rigging guides.
•ENDURADRIVE®Fan System mechanical braces are structurally required and are not removable.

2. 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.
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 the equipment at or near the fan’s “critical speed,” which could result in fan failure and
possible injury or damage. Before changing fan speed, consult your local BAC Representative and refer to the resonant speed
identification procedure available in the operation & maintenance manual.
: Failure to use appropriate lifting equipment 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.
Shipping
Models FXV3/CXVT are factory assembled to ensure uniform quality with minimum field assembly. FXV3/CXVT 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 submittal drawings.
: To prevent bodily injury or property damage, only qualified personnel qualified should
undertake the installation, 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

Unit Weights
Before rigging any unit, the weight of each section should be verified from the unit submittal drawing. Unit print weights include
the final assembled unit with all accessories.
: Equipment damage may occur if water, snow, ice, or debris has collected in the basin or
elsewhere in the unit. Such accumulations will add substantially to the equipment’s lifting weight placing equipment
at risk of damage that could result in injury. Before an actual lift is undertaken, ensure no water, snow, ice, or debris
has collected in the basin or elsewhere in the unit.
Anchoring
Seven-eighths inch (7/8”) diameter holes are provided in the bottom flange of the basin section for bolting the unit to the
support beams. Refer to the suggested support drawing included in the submittal for location and quantity of the mounting
holes. The unit must be level for proper operation. Anchor bolts must be provided by others. The IBC rating is only certified
with standard anchorage locations. Using alternate anchorage locations or alternate steel supports will void any IBC wind or
seismic ratings. Contact your local BAC Representative for details.
: Equipment damage may occur if the unit is not properly anchored before operation begins.
Equipment damage could result in death or serious injury. Ensure unit is properly anchored before operation beings.
