Chapter 1: Safety 1-1 How to Use This Manual Use this manual as a guide and reference for installing, operating, and maintaining your equipment. The purpose is to assist you in applying efficient, proven techniques that enhance equipment productivity. This manual covers only light corrective maintenance. No other maintenance should be undertaken without first contacting a service engineer. The Functional Description section outlines models covered, standard features, and optional features.
1-2 Warnings and Precautions Our equipment is designed to provide safe and reliable operation when installed and operated within design specifications, following national and local safety codes. To avoid possible personal injury or equipment damage when installing, operating, or maintaining this equipment, use good judgment and follow these safe practices: ; Follow all SAFETY CODES. ; Wear SAFETY GLASSES and WORK GLOVES. ; Disconnect and/or lock out power before servicing or maintaining the equipment.
Chapter 2: Functional Description 2-1 Models Covered in This Manual This manual covers fiberglass cooling tower models. Model numbers are listed on the serial tag. A model number followed by –Q is specially-constructed, and the information in this manual may not apply. Make sure you know the model and serial number of your equipment before contacting the manufacturer for parts or service.
2-4 Optional Features Side Outlet. The side outlet is used when the tower basin is used as a reservoir. Starter Package. The starter package includes a starter, a remote On/Off switch, a thermostat, and a well. Basin Reservoir. The basin reservoir includes an automatic float valve, overflow and drain connections, and an outlet basket strainer for towers with no inside reservoir. Basin Heater. The basin heater includes a heater and a low water level heater shutoff.
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.

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.
3-3 Rigging Handle the fiberglass cooling tower shell section very carefully. Until installed and properly supported, it is subject to handling damage. See Figure 2 for rigging information. Caution! Use an appropriately rated hoist to support the equipment. Figure 2: Rigging Arrangement Channel I-beam Spreader bar wide enough to protect cooling tower shell Rope stay Caution! Use appropriately rated hoist to support equipment.
Install the piping according to the piping diagrams in Figure 3 on page 14, Figure 4 on page 14, and Figure 5 on page 15.

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.
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.
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.
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.
