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

SERIES 3000 COOLING TOWER
Introduction
Unit Weights
Before rigging any unit, the weight of each section should be verified from the unit
certified drawing. Some accessories add additional weight as shown on the respective
accessory drawings.
Anchoring
Seven-eighths (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 location 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
Cold Weather Operation
These products must be protected by mechanical and operational methods against damage
and/or reduced effectiveness due to possible freeze-up. Please refer to the Series 3000
Operation & Maintenance Manual on www.BaltimoreAircoil.com, or contact your local BAC
Representative for recommended cold weather operation strategies.
Location
All evaporative cooling equipment must be located to ensure an adequate supply of fresh
air to the unit air intakes. When units are located adjacent to walls or in enclosures,
care must be taken to ensure the warm, saturated, discharge air is not deflected and
recirculated back to the air intakes.
Each unit should be located and positioned to prevent the introduction of discharge
air into the ventilation system of any building. For detailed recommendations on BAC
equipment layout, see our website at www.BaltimoreAircoil.com or contact your local
Representative.
Warranties
Please refer to the Limitation of Warranties (located in the submittal package) applicable
to and in effect at the time of the sale/purchase of these products.
Unit Operation
Prior to start-up and unit operation, refer to the Series 3000 Operation & Maintenance
Manual shipped with the unit and also available at www.BaltimoreAircoil.com.
NOTE: 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.
ATTENTION: Before an actual lift
is undertaken, ensure no 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.

Multi-Cell Installation
Refer to the submittal drawings for the proper orientation of each cell. The number and
“face” are stenciled on the outer basin wall. Multi-cell cooling tower installations may
employ flume boxes to equalize the water level in the basin of each cell. Follow directions
in “Flume Box Installation” for details on their installation.
Multi-Cell Unit Assembly
1. First, position the lower section of all cells on the unit supports and bolt in place.
Some units come furnished with a flume box. If they do, use the flume box assembly
procedure outlined in “Flume Box Installation” to connect the basins of the multi-cell
units.
2. Wipe any moisture and dirt from the perimeter mating flanges.
3. Install foam seal tape (BAC part # 270175) supplied with the unit, as illustrated in
Figure 3, on page 5 on the mating flanges of the lower sections in a continuous line.
At each corner, allow 1” overlap.
4. Complete assembly using the internal drift pin alignment guides:
–Using drift pins in the drift pin guides provided (Figure 7), guide the top section on
to the bottom section.
–Match marks must line up as shown in Figure 3 on page 5.
–Bolt the top sections onto the bottom sections as shown in Figure 4 on page 5 using
the bolting channels in Figure 6.
Flume Box Installation
1. Position Cell #1 on the unit support and bolt in place.
2. Wipe down the surface adjacent to the flume opening of Cell #1 to remove any dirt or
moisture that may have accumulated during shipment.
3. Wipe down the flanges on both ends of the flume box. On one end, apply a layer of
flat butyl sealer tape (BAC part # 554000) around the face of the flange over the
centerline of the holes. Do not overlap or stretch too thinly at the corners. When it is
necessary to splice the sealer tape, be sure to press the two ends together to form a
smooth, continuous strip. Apply a second layer of flat butyl sealer tape over the first
layer following the same procedure. Refer to Figure 8, Detail A.
4. Using drift pins to align the bolt holes, place the flume box over the opening in the
basin of Cell #1.
5. Fasten into place as shown in Figure 9. For basins with TriArmor®Corrosion Protection
System, backing plates are to be installed inside the basin and flume box opening (see
Figure 10, Detail A). Insert the 3/8” self-tapping screws or bolts in each hole from the
flume box into the basin wall and backing strips (if applicable) as illustrated in Figure
10.
NOTE: Flume boxes furnished
with units constructed with
TriArmor®Corrosion Protection
System or stainless steel basins
are assembled with stainless
steel bolts, washers and nuts
in lieu of self tapping screws.
Before installing the nuts, apply a
lubricant to the bolts to reduce the
potential for seizing.

SERIES 3000 COOLING TOWER
Optional Accessory Installation 3
ENDURADRIVE™ Fan System Installation (Optional)
The ENDURADRIVE™ Fan System is an option for select Series 3000 Cooling Towers and is
standard on S3E-1424-14U and S3E-1424-14W models. The ENDURADRIVE™ Fan System
variable frequency drive (VFD) is to be installed per the ENDURADRIVE™ Fan System ACH550-UH
HVAC User’s Manual. The fan motor must be wired directly into the VFD and cannot be wired across
the line. For wiring details, refer to the submittal drawings.
Warnings for the ENDURADRIVE™ Fan System
• WARNING: 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. Electrical shock can cause severe personal injury or death. Therefore,
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. Only qualified personnel should attempt the installation, operation and maintenance of this equipment.
• WARNING: Pacemaker danger − 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.
• WARNING: The VFD may apply hazardous voltages to the motor leads after power to the controller has been turned off. Verify that the
controller is incapable of delivering hazardous voltages and that the voltage at the motor leads is zero before proceeding. Failure to comply
with this warning may result in severe personal injury or death.
Attentions for the ENDURADRIVE™ Fan System
• VFD must be powered on at all times so that trickle current can remove moisture from motor when idle.
• Use only a shielded motor power cable with a complete circumferential braided or copper film/tape ground jacket around the power leads.
This ground should be secured to the motor frame from within the motor terminal box and must return without interruption to the drive
ground.
• To prevent equipment damage, be sure that the electrical service is not capable of delivering more than the maximum motor rated amps
listed on the rating plate.
