Tower Startup
Microorganisms including Legionella bacteria can exist in premise
plumbing including cooling towers. The development of an effective
water management plan (WMP) and implementation of maintenance
procedures are essential to prevent the presence, dissemination and
amplification of Legionella bacteria and other waterborne contami-
nants throughout premise plumbing. Before operating the cooling
tower, the water management plan and maintenance procedures
must be in place and regularly practiced.
WATER SYSTEM–Consult a knowledgeable water treatment professional to
clean and treat your new cooling tower prior to startup. Cooling towers must
be cleaned and disinfected regularly in accordance with local public health
services and recommendations. Do NOT attempt any service unless the fan
motor is locked out.
Remove any dirt and trash which has accumulated in the cold water basin.
Remove any sediment from the cold water collection basin, sump, and screens.
Use a water hose to flush cold water collection basins.
Fill the cold water collection basin and circulating water system until the op-
erating water level is reached.
OPERATE WATER SYSTEM–Prime and start the circulating water pumps.
Increase the flow of circulating water gradually to design water flow rate to
avoid water hammer which could damage the distribution piping system.
Increase the flow of circulating water gradually to match design water flow
rate. Circulate water over the cooling tower continuously for several days
before starting the mechanical equipment and placing the cooling tower into
continuous operation.
When starting in freezing weather, follow procedures outlined in
Freezing Weather Operation.
INSPECTION–It is imperative that all operating assemblies be inspected
before they are placed in operation. The following is a list of components to
be checked before starting the tower:
1–Check tightness of bolts in fan hood joints.
2–Check bolted joints in the fan and gear motor drive assemblies.
3—Check the piping connection hardware
Warning
Note

4—Visually inspect the fill, drift eliminators, air inlet louvers and the distribution
piping and spray nozzles.
5–Check gear motor oil for sludge or water by draining off and testing a sample
as outlined in the manufacturer’s Gear Motor IOM Manual. Check gear
motor oil level. Add oil as required. Refer to the Gear Motor IOM Manual
for oil filling procedure and list of recommended lubricants.
6–Rotate fan by hand to be sure of free rotation and ample tip clearance.
7–Test run each fan separately for a short time. Check for excessive vibration
or unusual noise. If either is present, see Troubleshooting Guide on pages
14 and 15 of this manual. Fan must rotate clockwise when viewed from
above. Recheck gear motor oil level.
8–Check functioning of make-up water supply. Make sure the blowdown will
carry the proper amount of water.
Clean the sump screens several times during the first weeks of
operation. After this, clean sump screens weekly.
STARTING FAN–Operate the fan for 30 minutes to permit the gear motor oil
to come up to operating temperature and check the motor load with a watt
meter, or take operating volt and ampere readings and calculate motor hp. Pitch
fans if required to pull correct contract horsepower when circulating design
water rate at design hot water temperature. Refer to the manufacturer’s Fan
IOM Manual for instructions. Check tightness of fan blade fasteners after a
brief period of operation.
Entering water temperature in excess of 80°C may result in fill de-
formation.
TOWER PERFORMANCE–Keep the cooling tower clean and water distribu-
tion uniform to obtain continued maximum cooling capacity.
The capacity of a cooling tower to cool water to a given cold water temperature
varies with the wet-bulb temperature and the heat load applied to the cooling
tower. As the wet-bulb temperature drops, the cold water temperature also
drops. However, the cold water temperature does not drop linearly with the
wet-bulb temperature.
A cooling tower will not control heat load. The flow rate of water circulated
through the cooling tower will determine the temperature range of cooling in
conjunction with a given heat load. The hot water and cold water temperatures
will increase with higher heat loads.
Note
Caution
operation

5
HOT WATER DISTRIBUTION SYSTEM–Maintain uniform water distribution
at the nozzles (uniform spray cone). The amount of water circulated should
approximate the contract requirements and the nozzle pressure should be kept
constant. Lower pressures may indicate excessive losses in the piping system
and/or insufficient pump capacity; greater pressures might indicate clogged
nozzles and/or overpumping. If a greatly reduced water flow rate is desired, it
may be advisable to change nozzle sizes to obtain the desired pressure and
maintain proper water distribution. An SPX Cooling Technologies engineer
can advise minimum and maximum flow rates for even distribution.
COLD WATER COLLECTION BASIN–A suitable depth must be maintained
to keep the pumps from pulling air into the line. The amount of “make-up”
water required to keep the water in the collection basin at the required depth
depends upon the “evaporation loss” and “blowdown” .
FREEZING WEATHER OPERATION–During periods of low temperature
operation, 2°C to 5°C or below, ice will form on the relatively dry parts of the
cooling tower that are in contact with the incoming air. Primarily, this includes
the air inlet and adjacent structural framing. Your understanding of cold weather
operation will be enhanced if you read “Cooling Towers and Freezing
Weather” Technical Report H-003 available at spxcooling.com.
Ice forming characteristics on any given cooling tower will vary, depending on
velocity and direction of wind, circulating water rate, and heat load. Excessive
ice formation may be controlled by regulating air and water flow through the
tower by one or more of the following procedures:
1–Shut the fan down. This reduces the cooling air rate to a minimum and in-
creases the quantity of warm water at the air inlet to a maximum. However,
normal “fan off” operation causes reverse air flow by aspiration and may
cause water blowout and therefore must be done with caution and moni-
toring. For automatic operation, a timer switch can be provided to shut the
fan down for a few minutes each hour.
2–If the cooling tower has VFD, operate the fans at half speed forward. This
reduces the cooling air rate (heat transfer) and increases the quantity of
warm water at the air inlet.
3–With no heat load on the circulating water, icing cannot be controlled. Towers
must not be operated with reduced water rate and/or no heat load during
freezing weather. If a bypass directly into the cold water basin is used, all
water must be bypassed.
operation

6
Reverse operation of fans is not recommended.
INTERMITTENT OPERATION–When the unit is operated intermittently dur-
ing freezing weather, it is necessary that the water be drained from the tower
piping to insure protection against freezing and possible rupture.
Always shut off electrical power to the tower fan motor prior to
performing any inspections that may involve physical contact with
the mechanical or electrical equipment in or on the tower. Lock out
and tag out any electrical switches to prevent others from turning
the power back on. Service personnel must wear proper personal
protective clothing and equipment.
Well-maintained equipment gives the best operating results and the least
maintenance cost. SPX recommends setting up a regular inspection schedule
to insure effective, safe operation of the cooling tower. Use the schedule on
page 19 to obtain continuously good performance with the least tower main-
tenance. See Cooling Tower Inspection Check List in this manual. Keep a
continuous lubrication and maintenance record for each cooling tower.
HOT WATER DISTRIBUTION SYSTEM–Keep the circulating water and
distribution system (piping and nozzles) clean and free of dirt, algae, and scale.
Algae and scale may clog nozzles, eliminators, fill, and piping, and may collect
on the equipment served thus reducing its performance.
The interior of the cooling tower can be accessed through an inspection door
located on the side casing. This will provide access to the water distribution
system, eliminators and fill.
Caution
Warning

DRIFT ELIMINATORS–Eliminators should be kept clean.
Do not walk or step on the eliminators.
COLD WATER COLLECTION BASIN–Inspect collection basin occasionally
for leaks and repair if necessary. Keep cold water outlets clean and free of
debris. Makeup and circulating water controls must operate freely and maintain
the desired water quantity in the system.
Do not walk or step on the fan hood.
The gear motor is located on top of the fan hood. A ladder and platform is
provided for access. The fan guard can be removed in sections for fan main-
tenance.
GEAR MOTOR–Make weekly and monthly oil checks. Inspect internal part
during seasonal oil change. Lubricate and maintain each gear motor in ac-
cordance with the manufacturer’s instructions. If repair work is necessary,
contact the nearest representative of the gear motor manufacturer.
FAN–Inspect fan blade surfaces every six months. For detailed maintenance
information, refer to the manufacturer's Fan IOM Manual.
PAINTING–Periodically clean and, if necessary, recoat all metal parts subject
to corrosion.
COLD WATER COLLECTION BASIN—A section of the air inlet louvers can
be removed to access the cold water collection basin. Remove both star
screws and the top fastening strip. The louver segment can be removed as
a block in one piece.

Water Quality and Blowdown
BLOWDOWN–Blowdown, or bleed-off, is the continuous removal of a portion
of the water from the circulating system. Blowdown is used to prevent the
dissolved solids from concentrating to the point where they will form scale.
The amount of blowdown required depends upon the cooling range (the dif-
ference between the hot and cold water temperatures) and the composition
of the make-up water (water added to the system to compensate for losses
by blowdown, evaporation and drift). The following table shows the amount
of blowdown required to maintain different concentrations with various cool-
ing ranges:
BLOWDOWN–% OF CIRCULATING RATE
EXAMPLE: 159 m3/hr circulating rate, 10°C cooling range. To maintain
4 concentrations, the required blowdown is 0.458% or .00458 times
159 m3/hr, which is .73 m3/hr.
If tower is operated at 4 concentrations, circulating water will contain four
times as much dissolved solid as the make-up water, providing none of the
solids form scale or are otherwise removed from the system.
CHEMICAL TREATMENT–In some cases chemical treatment of the cir-
culating water is not required if adequate blowdown is maintained. In most
cases, however, chemical treatment is required to prevent scale formation and
corrosion. Sulfuric acid or one of the polyphosphates is most generally used
to control calcium carbonate scale. Various proprietary materials containing
chromates, phosphates or other compounds are available for corrosion control.
When water treatment chemicals are required, the services of reliable water
treating companies should be obtained.

Biofilm, a gelatinous organic growth, and algae, a green moss, may grow
in the cooling tower or heat exchangers. Their presence can interfere with
cooling efficiencies. Proprietary compounds are available from water treating
companies for the control of slime and/or algae; however, compounds which
contain copper are not recommended. Chlorine and chlorine containing
compounds are effective algaecides and slimicides. If used, chlorine should
be added as intermittent (or shock) treatment only as frequently as needed
to control the slime and algae. Chlorine and chlorine containing compounds
should be added carefully since very high levels of chlorine may occur at or
near the point of entry into the circulating water system.
FOAMING–Heavy foaming sometimes occurs when a new tower is put into
operation. This type of foaming generally subsides after a relatively short pe-
riod of operation. Persistent foaming can be caused by the concentrations of
certain combinations of dissolved solids or by contamination of the circulating
water with foam-causing compounds. This type of foaming can sometimes be
minimized by increasing the blowdown, but in some cases foam depressant
chemicals must be added to the system. Foam depressants are available from
a number of chemical companies.
Maintenance of Fill Performance
Water must be kept clean by treatment, screening, or filtering to
avoid the possibility of fill clogging and loss of thermal performance.
Potential Causes of Fill Clogging:
• Debris and suspended materials.
• Scale—Can be sulfates, silicates, carbonates, or oxides. Scaling effects can
be accentuated by suspended solids.
• Algae and/or Biofilm—Can control with chlorine or non-oxidizing biocides.
Possible Sources of Scale:
• Calcium Sulfate—From make-up and sulfates produced by sulfuric acid for
pH adjustment. Calcium sulfate should be kept below 1000 ppm expressed
as CaCO3.
• Calcium Carbonate—Generally will not form scale in the cooling tower if
carbonate scaling does not occur in the condenser.
• Exceptions: If make-up water contains surplus free carbon dioxide, scaling
may be inhibited in the condenser, but may occur in the tower fill because
of CO2stripping.
Warning

• Silicates and Oxides—Silica scale is virtually impossible to remove. Silica
scale is unlikely if SiO2is held below 150 ppm. Oxides, such as iron oxide,
can coat all parts of the system if soluble iron is present in concentrations
above 0.5 ppm. Iron oxides do not usually develop into thick scales but can
accentuate the development of other scales.
Do not walk directly on the fill. Place appropriate walking surface
on fill to avoid crushing. Recommended walking surface would be a
minimum of 15mm thick plywood measuring at least 30cm x 60cm.
Spare Parts
SPX Cooling Technologies manufactures and inventories cooling tower re-
placement parts. Typical lead time is 10 working days. Contact your Marley
representative for emergency service.
Owners should consider maintaining inventory of critical mechanical compo-
nents, such as a fan assembly and gear motor to avoid emergency shutdown
of cooling tower operations.
Be sure to furnish the tower serial number when ordering parts.
