Chapter 3: Installation
3-1 Tower Installation Location
Roof Installation
Select a location over or nearest to the heaviest building structural members. These members
should be outside load-bearing walls, building columns, or roof joists. You may need to
spread the load over several structural members to provide support without over-stressing any
one member. See Figure 1 on page 11 for structural steel support requirements. You are
responsible for contacting a structural engineer to verify support requirements.
Choose a site with easy access to simplify routine maintenance. This consideration is
especially important when a tower is located near a roof edge.
Avoid locations where wind currents can re-circulate tower discharge air.
Stay clear of roof discharge points. Avoid stacks, exhaust fans, dust collector discharges, or
any process that can contaminate air circulating through the tower.
Caution! Multiple tower installations require at least five feet (60”/ 152cm) clearance
between towers to reduce freeze-ups. The manufacturer is not responsible for
damages resulting from improper site selection.
Ground Installation
Elevate the tower so that positive pressure is on pump suction and to allow maintenance
access to the underside of the tower cell.
Alternative Installations
Outside Installation with the Pump Tank Reservoir Inside. Water exits the tower and
drains to a pump tank reservoir inside the building below. The tower outlet must be at least
three feet (approximately 1 meter) above the top of the pump tank. The outside tower basin
must drain completely when shut down to avoid winter freeze up.
Outside Installation Using the Tower Basin as a Reservoir. Process pump suction piping
is directly connected to the bottom outlet on the tower. Install the optional outlet basket filter
and automatic float assembly. Contact the Sales department for this accessory kit.
Note: A dimension of 60”is required between the tower air inlet and the wall of a
building. See above caution for required distance between towers.

3-2 Assembling the Cooling Tower in the Field
Your cooling tower may have been shipped on two skids to reduce shipping charges.
One skid contains the lower section, identified by the black fill wrapped in plastic on the
inside of the lower section. The second skid contains the top tower section bolted over the
fan/motor assembly. Perform the following procedure to properly assemble the two sections
if the sections shipped separately.
1. Remove the clear plastic protective wrapping from the fill.
2. Inspect both sections for any damage, and locate the red orientation mark on one of
the vertical sides of each section.
3. The manufacturer supplies self-adhesive gasketing material to insure a water-tight
seal between the top and bottom sections. Install this material on the top of the
attachment flange on the lower section prior to mating the top and bottom sections.
Make sure that the flange is clean, dry, and free of rough spots before applying the
gasketing material.
4. Align the holes in the gasket with the bolt holes in the flange, then remove the paper
on the back side. Cut the gasketing material to fit properly, and apply the gasket to
the flange as you realign gasket holes with flange holes. Repeat on all four sides of
the tower.
5. Apply silicone caulk in cut lines and voids to complete sealing between sections.
6. Unbolt the top section from the skid and make sure that the flange on the top section
is clean, dry, and free of rough spots.
7. Place the upper section on the gasketed lower section, aligning the red orientation
marks. Take care not to disturb the gasketing and silicone caulk while aligning bolt
holes.
8. After aligning, bolt the two sections together with the fasteners provided. Use a flat
washer under the bolt head on top and a flat washer, a lock washer, and nut on the
bottom side of the flange.

vertical rope in position.
Do not let the rigging transfer any load to the cooling tower shell. Provide support to
the bottom of the cooling tower when rigging. Do not rig from the corners of the
optional base. Do not rig less than 8 inches from the corners.
3-4 Installing the Fan Package
Install the fan package after the tower is in position.
1. Remove the dunnage securing the fan package to the pallet.
2. Carefully rig the package using the lifting eyebolts provided.
3. Mounting holes have been pre-drilled at the factory; move the package into position
and fasten it securely with the stainless steel hardware provided.
3-5 Installing Piping
Make sure that all piping attached to the cooling tower is externally supported. Do not
support anything from the cooling tower shell.
The cooling tower and related fittings and connections are constructed of plastic materials
and are not designed to bear external weight.
Do not apply high torque to the fittings that are made up into the tower fittings. Use a backup
wrench when applying torque to the fittings.

3-6 Setting Up the Water Balancing Valve
Install the plug provided in the unused water inlet on the side of the tower. Tighten and check
for leaks.
To prevent damage to the tower fill material, use the water throttling valve and pressure
gauge to regulate the water pressure to the tower spray nozzle(s). The recommended
throttling valve is a butterfly-type valve that can be locked in the correct position with a
locknut. See Figure 6 for recommended throttling valve pressures.

Warning! Exceeding these pressure limits will damage the tower fill and nozzle and void
the tower warranty.
3-7 Initial Start-up
Check for proper rotation on all fan and pump motors. Refer to the arrows atop the tower and
on pump housings.
Fill the system with water and adjust the float valve if you are using a float. Maintain a water
level in the tower basin approximately one inch (25 mm) below the overflow opening.
The tower basin acts as a sump to maintain water level. Towers using inside tanks do not
carry water in the basin.

Chapter 4: Operation
4-1 Bleed-Off and Evaporation Rates
A proper bleed-off rate is important to limit the concentration of minerals and foreign
materials in re-circulated water. A bleed-off equal to the evaporation rate, normally about two
gallons per hour per ton (7.57 liters per hour per 3,780 Kcal/hr), is sufficient for many
makeup water conditions. Refer to the suggested bleed-off arrangements in Figure 3 and
Figure 4 on pages 14 and 14 for more information. For automatic bleed rate control, a
conductivity controller is available through the Sales department.
4-2 Winter Operation Considerations
All cooling towers are subject to ice formation in sub-freezing weather. Your cooling tower
requires a certain amount of attention and maintenance to prevent damage during these
operating conditions.
Follow these guidelines to reduce the chance of ice buildup:
• Maintain full design flow. Any reduction in water flow greatly increases the
probability of ice forming on and around the air inlet louvers.
• Do not use free cooling applications during freezing weather. Reduced water
temperatures or loading dramatically increases the chance of ice formation. Make sure
that the leaving water temperature is set above 80ºF (27ºC) during sub-freezing
weather so heat from the water warms the air inlet louvers and reduces ice formation
when the fan is off. Using a thermostat to control fan cycling by leaving water
temperature is mandatory.
• Do not run fans backward to thaw ice. Ice can form on the fan ring, fan guard, and
support structures, and can severely damage fan blades. Reversed airflow can also
blow water vapor out onto the roof and create ice fields around the cooling tower.
• Maintain a heat load of at least 60% of tower capacity at all times during operation in
freezing weather. A lack of substantial load can create uneven temperatures in the
tower and cause freezing.
• If you shut down your cooling tower during freezing weather, you must drain it
completely. We recommend that you use an indoor reservoir tank to permit water to
drain into the tank on system shutdown, whether for emergencies or actual planned
shutdowns.
• An alternative is to use basin heaters if a tower basin is used as a sump. Basin heaters
are available as an option. However, basin heaters can permit freeze-up during power
failures if water remains in the sump. The customer is responsible for determining risk
factors for each specific application.

Chapter 5: Maintenance
5-1 Preventative Maintenance
Water Treatment
Control of slime, algae, and bacteria growth is extremely important. Cooling towers and
reservoir pump tanks are superb environments for microorganism growth. Warm water,
organic debris, and air encourage bacterial growth. Treat your system with chemicals
(microbiocides) to control microorganism growth.
Caution! Uncontrolled microorganism growth causes system problems such as fouling
and corrosion, and can spread bacterially-transmitted diseases.
You must reduce slime growth and bacterial contamination to eliminate disease-causing
bacteria.
Properly used, environmentally approved microbiocide controls system bacteria. Chemical
treatments must be regularly monitored by qualified personnel.
The manufacturer strongly recommends use of EPA-registered microbiocides on a regular
basis. We do NOT recommend use of chlorine or backyard swimming pool chemicals.
Permitting the discharge of such chemicals into a city sewer may violate local, state, and/or
federal laws.
We offer a full-service water treatment program including chemicals, dispensing equipment,
automatic bleed-off, and monthly water analysis. Contact the Parts and Service department
for more information.
Routine Maintenance
• The fan motor has double-sealed bearings and needs no lubrication
• Inspect basket strainers (where used) and clean as needed.
• Check constant bleed back to the tank for flow during operation.
• Check the bleed-off line to verify that water flows to the drain during operation.
• Inspect the tower basin for dirt and debris, and clean as needed.
• Check the tower nozzle(s) for proper operation at full water flow.
• Check the water treatment equipment for proper operation. Refer to the information
supplied with these devices.
• Check the throttling valve pressure gauge. The pressure should be within the
recommendations in section 3-6.

5-2 Corrective Maintenance
Replacing Nozzles and Fill
The PVC fill used in these cooling towers provides years of maintenance-free service under
normal conditions. If you discover dirty water or defective nozzle(s) damage the fill, you can
order a replacement kit from the parts department.
You can easily remove and replace the fill by removing the tower access door on the side of
the tower. Open the door to gain access to the nozzle system.
