ABOUT THIS MANUAL
To obtain maximum efficiency, it is strongly recommended that this entire manual be read
before starting installation. This manual illustrates a typical field installation sequence of a
basic tower. Some common options are also included. Refer to separate installation drawings
for additional optional equipment Review all manuals, drawings and bills of material prior to
assembly. These documents are located in a Literature Kit packed with the tower. Contact
your SPX Cooling Technologies sales representative should questions arise.
SAFETY
The location and orientation of the cooling tower can affect the safety of those responsible for
installing, servicing, or repairing the tower. Since SPX Cooling Technologies does not dictate
the location, or orientation of the tower, SPX Cooling Technologies is not responsible for
addressing the safety issues that are affected by the tower's location, or orientation. The
following safety issues should be considered by those responsible for designing the tower
installation. Failure to consider and address these issues may result in substantial personal
injury, or death to those involved in installing, servicing, or repairing the cooling tower.
* Access to and from maintenance access doors
* Access for cleaning and other service
* Potential access problems due to obstructions surrounding the tower
* The possible need for ladders (either portable or permanent) to gain access to the
maintenance access doors
* The possible need for safety cages around ladders.
These are only some of the safety issues that may arise in the design process. SPX Cooling
Technologies strongly recommends that you consult a safety engineer to be sure all safety
considerations have been addressed.
SPX Cooling Technologies offers optional equipment that may assist you in addressing
some of these safety issues. Consult your sales representative for information on these
optional items.
Safety is the first priority at the job site. Cooling towers are constructed of material that
could cause injury if not handled properly. It is recommended that Kevlar gloves and sleeves
and eye protection be worn at all time when working with steel, PVC and fiberglass. Hardhats
should be worn when working with overhead objects.
Steel parts may be heavy and the surfaces may be slick from oil used during fabrication. Take
precautions by placing heavy steel parts near or on the ground to minimize the risk of dropping.
Although all steel parts are de-burred, the edges of steel can be very sharp and cut easily.
Keep a first aid kit handy should the need arise.
Use the above suggestions as well as common sense to create a safe working environment.
Take steps to prevent tipping or falling hazards. Protection from thrown or falling objects
should be used at all times around a construction site. Keep the worksite and assembly area
clean. Check tools periodically and replace tools that could break or malfunction. Follow
instruction manuals for all powertools and beware of shock hazards that exist.
NEVER HOLD A PIECE OF STEEL IN PLACE USING ONLY A DRIFT PIN. Drift pins have
smooth surfaces and are designed to slide in and out of holes very easily. Drift pins can not
hold themselves in place. Parts WILL fall if suspended only by a drift pin.
PARTS
All steel parts are tagged for identification, as shown above.
Find Number: This is a three-digit alpha/numeric number that ties the bill of material
(BOM) to the drawings. They are identified in the drawings as the alpha/numeric
numbers within the circles. The find numbers on the drawings are used in conjunction
with the appropriate BOM to find the correct item numbers needed for installation.
THE SAME FIND NUMBERS MAY BE USED FOR DIFFERENT PARTS ON
DIFFERENT TOWER CELLS.
Item Number: This number is used by SPX Cooling Technologies to purchase,
manufacture and inventory the components of the modules. Give these item numbers
to the project manager if an item is missing or a replacement item is required.
Drawing Number: (Reference Only) This is the number of the drawing used to fabricate
the item. This number DOES NOT reference the drawing number where the part is
used.
Description: (Reference Only) This number describes the dimensions of the flat pattern
of the item. These dimensions MAY NOT correspond to the overall dimensions of the
part.
The find number, item number, description and quantity of items are all cross
referenced on the bill of material. If a number is missing or hard to read, check the
illustrations in this assembly manual first and then the bill of material to see if you can
find it. As the tower is prepared for assembly, the quantities of each item should be
checked against the bill of material.
NEED HELP!
If anything is missing, damaged, or you need help of any kind, contact your SPX
Cooling Technologies Representative as soon as possible. If you need help
determining the representative in your area, please call us at 1-800-4MARLEY, or
check the internet at www.spxcooling.com

MEASUREMENT SYSTEM
The manual uses both, the English System and Metric System of
measurement. All units are in millimeters. Fasteners are denoted in both the
English and metric systems. Fasteners are supplied in conformance with the
metric system standard unless otherwise noted in the tower bills of material.
TOOLS AND SUPPLIES
Hoist: 3,500 pound capacity for hoisting largest tower module. They cannot
be lifted/moved with a forklift from the bottom.
Small and large drift pins: (alignment tools) these are extremely important to
help line up all the holes.
Combination wrenches: mainly 13mm up to 30mm. May be substituted for
impact wrenches.
Socket wrench set: Tower mainly uses 13mm, 19mm & 30mm sockets.
have more than one if possible.
Impact wrenches (electric or pneumatic) with standard and deep sockets:
used to tighten all hardware.
Pipe wrenches
Allen wrenches
Torque wrench: 100 ft lb (136 N-m) capacity.
Utility knife, Cutting pliers: used to open boxes and unwrap pallets.
Caulking guns: application of sealer to steel and casing.
Acetone solvent: use with clean cotton rags to wipe down steel before
applying sealant.
Protractor level: For setting fan blade pitch
Dial Indicator kit: marley item No. 115311. For drive shaft alignment.
Needed for motor outside airstream option only.
Scoffolding, portable stairs, ladders or other means of temporary access
and support
Wear protective clothing, gloves, nonslip footwear, hard hat and safety
glasses. Fluid Coolers are constructed of steel and could have burrs that can
cause cuts. The surface of the steel could be slick. Protection from thrown,
or falling objects should be used at all times around a construction site.
A FEW WORDS ABOUT FASTENERS
Stainless Steel Fasteners:
Stainless steel fasteners are prone to galling. This is when you notice a sudden increase in the force needed to
turn a nut before parts are clamped. Apply anti-seize compound to the threads of the bolt before installing the
nut. If a nut does not easily spin on a bolt, do not try to force it. Chances are it will seize. Some extra hardware
is included to replace problem hardware.
Tap Screw Repair:
During installation of tap screws in sheet metal parts, tap screws may strip, not allowing the screw to be fully
tightened. if this occurs, place a 3/8" [10mm] nut on the back side of the tap screw and tighten.
Torque requirements:
The idealized standard fastener torque values for galvanized and stainless steel fasteners are shown in the
table below. These values may vary in actual practice. Note that the values shown for stainless steel fasteners
are based on the fasteners being lubricated with anti-seize compound.
Loctite®
Critical structural and mechanical attachments require extra protection against the nuts vibrating loose during
tower operation. This is accomplished on galvanized fasteners by applying Loctite, Find# Z05, thread locking
compound to the exposed threads of a bolt after the nut has been installed and tightened. Bolts should be
installed with the threaded end up or horizontally. Reference details below. On stainless steel fasteners the
use of anti-seize compound makes the use of loctite ineffective. Therefore in these critical areas with stainless
steel fasteners, self-locking nuts have been substituted for the standard nuts and loctite will not be used.
GENERAL DECAL INSTRUCTIONS
Decals are an important part of the tower assembly. Decals provide instructions, identifications, cautions and
warnings deemed necessary for proper operation and safety.
Surface Preparation
Surface must be clean and dry. Oil and dirt may be removed with solvent (such as acetone) or commercial
detergent. Wash the area with warm water and dry with a lint-free cloth. Ultimate adhesion will occur 24-28
hours after application should not be undertaken if temperature is below 35 degrees Fahrenheit, or if humidity is
greater than 95%.
General Application Instructions
Peel off backing paper, taking care to avoid dirt contamination of the exposed adhesive. Carefully apply decal to
the desired location with light pressure to avoid distortion of the vinyl. Once in position, smooth out with a towel.
If air bubbles occur, puncture with a pin and smooth down with a towel. The finished decal should be completely
flat.

JOINT SEAL INSTRUCTIONS
The following information covering surface preparation applies to all sealed joints whether
sealer Z11 or strip sealer Z12 and/or Z13 is being used. The typical joint sealing details shown
on this page may be referenced throughout this manual or other optional equipment
installation drawings. Years of experience has shown the instructions on surface preparation
and sealing details do result in watertight joints. Inadequate attention to the details will result in
joints that leak. Do not apply either sealer if temperature is below 40 degrees Fahrenheit (5
degrees Celsius).
All flanges are to be straight. Rework kinks or bends that exist. Clean surfaces being sealed
solvent. If cloth is used, it must always be clean and dry. Exercise caution in using solvents,
always read labels and instructions. Care should be taken not to wipe dirt or oil onto the
cleaned surface from adjacent uncleaned area. Mating surfaces to be sealed must be kept
clean and dry prior to assembly. No water, grease or dirt should contaminate cleaned area.
Note that stainless steel requires a larger area to be cleaned because oil will contaminate
surfaces quickly. Oil will migrate through punched holes and around sheared edges.
Application instructions for Tube Sealer Z11 (Type A, B, & C seals):
Tube sealer, Find# Z11, cones in a 1/12 gallon (315ml) cartridge and is applied using a
standard caulking gun. Apply sealer to unassembled parts. Care should be taken to fill voids
and gaps at joints. After parts have been assembled, trowel excess sealant over joint, taking
care to force sealant back into joint, not out of joint. Do not use solvent to aid in applying
sealer. Solvent adversely affects bonding of sealant to metal. Care should be taken to avoid
leaving holes, or bubbles in sealant. Do not subject sealed joints to waterloading for 48 hours
at temperatures of 70 degrees Fahrenheit (21 degrees Celsius) and above. Lower
temperatures will require a longer cure time.
Application Instructions for Strip Sealer Z12 & Z13 (Type D, E, F & G seals):
Strip sealer is supplied an 1/2" (13mm) Z13 and 1" (25mm) Z12 widths. It is intended that the
1/2" (13mm) wide sealer be used unless otherwise noted. Apply continuous pieces of strip
sealer to the unassembled parts. Do not splice pieces except when turning a corner. Cut with
a sharp knife, do not stretch, or tear. Gaps at joints and corners can be filled by spanning a
piece of strip sealer to gain the proper thickness. Then work it into the joint to fill gaps and
greate an even surface. After parts are set together, use a drift pin, or other pointed object, to
puncture sealer at each fastener hole where required.

If collection basins of multiple towers
are to be connected together, a flume is
installed as shown.
Flume collars are shop installed in
each tower along with temporary
coverplates for shipment. Remove
coverplates before continuing. Note that if
a weir gate option (a removable plate
used to isolate adjacent towers) has been
purchased, the weir gate is shop installed,
in one tower, for shipment. The weir gate
will be reinstalled, in either tower, after
installation of flume per the next page.
Note that towers must be aligned
before attempting to install flume in place.
Sealing of the flume connections is critical
to prevent leaks. Apply a 1/2" [13mm]
bead of sealer Z11 as indicated, around
and between all holes on both flume
collars. Install non-joggled flume corners
Q11 first. Apply another bead of sealer
around and between holes where joggle
will overlap on flume. Complete flume
installation by installing joggled flume
corners Q15. If weir gate option is
purchased, ends of flume corners must be
flush to ensure a proper seal.
