PFi Closed Circuit Cooling Towers and PCC Evaporative
Condensers should be rigged and assembled as outlined
in this manual.
These procedures should be thoroughly reviewed prior to the
actual rigging and assembly of the equipment to acquaint
all personnel with procedures to be followed and to ensure
that all necessary equipment will be available beforehand.
If outstanding circumstances require a departure from the
procedures outlined in this manual, contact your local BAC
Representative for guidance.
Be sure to have a copy of the submittal drawings available for reference.
If you do not have a copy of these drawings, or if you need additional
information about this unit, contact your local BAC Representative whose
name and telephone number are on the outside of the cold water basin. The
model number and serial number of the unit are also located in this area.
Some parts that ship loose are labeled with unique three key codes for
identification purposes. These three key codes are referenced throughout this
guide to identify parts to be assembled in the field.

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 and follow 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. Refer to
“Fan Control” in the PFi and PCC Operation & Maintenance Manual on
www.BaltimoreAircoil.com.
Shipping
BAC PFi Closed Circuit Cooling Towers and PCC Evaporative Condensers are factory
assembled to ensure uniform quality with minimum field assembly. This product ships
in either two or three sections per cell, 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.
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.
The following parts should be inspected:
Sheaves and Belts
Bearings
Bearing Supports
Fan Motor(s)
Fan Guard(s)
Fan(s) and Fan Shaft(s)
Float Valve Assembly(s)
Water Distribution System
Coil Surface
Cold Water Basin Accessories
Interior Surfaces
Exterior Surfaces
Louvers
Spray Water Pumps
Mating Surfaces Between
Sections/Modules
Miscellaneous Items: All bolts,
nuts, washers, and sealer tape
required to assemble sections or
component parts are furnished by
BAC and shipped with the unit.
A checklist inside the envelope
attached to the side of the unit
marked “Customer Information
Packet” indicates what
miscellaneous parts are included
with the shipment and where they
are packed. This envelope will be
attached to the side of the unit or
located in a box inside the unit.
WARNING: Failure to use
designated lifting points 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: The operation,
maintenance, and repair of this
equipment shall be undertaken
only by personnel authorized
and qualified to do so. All such
personnel shall be thoroughly
familiar with the equipment, the
associated system and controls,
and the procedures set forth in
this manual. Proper care, personal
protective equipment, procedures,
and tools must be used in handling,
lifting, installing, operating,
maintaining, and repairing this
equipment to prevent personal
injury and/or property damage.

Introduction
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.
Accessory weights (found on the respective drawing) can be deducted from the total
weight.
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.
Nitrogen Charge of Condenser Coils (PCC Only)
As of June 2017, condensers shipped from the factory are charged with nitrogen to
15 psig. Relieve the pressure then cut and bevel coil connections in accordance with
generally accepted industrial practices. If the unit arrives without the holding charge, it
is reccomended a test be placed on the coil before installing. If you have any questions,
contact your local BAC Representative.
Cold Weather Operation
These products must be protected by mechanical and operational methods against damage
and/or reduced effectiveness due to possible freeze-up. Refer to “Cold Weather Operation”
in the PFi and PCC 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 fans. 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 short-circuited
back to the air intakes.
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 detailed recommendation 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 PFi and PCC Operation & Maintenance
Manual shipped with the unit and also available at www.BaltimoreAircoil.com

CAUTION: 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.
CAUTION: 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.
NOTE: Location must comply with
all local codes and regulations.
CAUTION: Removing the coil
connection cap before releasing the
pressure can cause personal injury.
Use the valve to relieve pressure.
