To avoid possible personal injury or equipment damage when installing, operating, or maintaining this equipment, use good judgment and follow these safe practices: þ Follow all SAFETY CODES. þ Wear SAFETY GLASSES and WORK GLOVES. þ 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 Bottom Outlet. The bottom outlet allows complete drainage of the basin. It is used with factory-installed remote inside reservoirs only. Water Balancing Valve. The water balancing valve includes a butterfly-type balancing valve and pressure gauge with fittings Starter Package. The starter package includes a starter, a remote On/Off switch, a thermostat, and a well. Basin Reservoir.
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.
3-4 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.

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 13 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.
