DRIFT PIN GUIDES

SPREADER BAR

SECTION ASSEMBLYSeries 1500 and Series 3000 Cooling Towers

To assemble a two-section unit, position the bottom section on the tower support and bolt in place. Install sealertape on the mating flange of the bottom section to ensure an airtight seal between the top and bottom section.Using drift pins in the bolt holes provided, guide the top section onto the bottom section. Match marks must line upas shown in Figure 7a. Bolt in place as illustrated in Figure 7a, Detail “A". Series 1500 towers use 5/16” self-tapping screws. Series 3000 towers use a 1/2” bolt and flat washer. In addition, a seal washer should be usedunder each nut to prevent water leakage.

Note: On multi-cell installations, for Series 1500, it is suggested that cells subsequent to the first, have the top andbottom sections assembled on the support foundation adjacent to the final mounting locations. This will allowspace for securing the top and bottom sections of each cell. Slide the subsequent cell(s) to their final positionusing the lifting devices at the base of the cell(s). Refer to the “Assembly of Multiple-Cell Units” section for details.All multi-cell units have the cell number and “face” identified on each section as well as match marks to show howthe cells are to be mated.

Note: On multi-cell installations for the Series 3000, position the bottom sections on the tower support and bolt inplace. Install foam tape on the mating flanges of the bottom section to ensure an airtight seal between the top andbottom section. Using drift pins in the drift pin guides provided (shown in Figure 7b), guide the top section on to thebottom sections. Match marks must line up as shown in Figure 7a. Bolt the top section onto the bottom section atthe alternate locations as shown in Figure 7a Detail, “A” and Figure 7c. Series 3000 towers use a 1/2” bolt and flatwasher. In addition, a seal washer should be used under each nut to prevent water leakage.

ASSEMBLY OF MULTI-CELL TOWERSFXT Cooling Towers

Multi-cell FXT’s (Models FXT-230, 260, 272, 320, 350, 384, 432, 480, and 514) are furnished with a flume box toequalize the water level in the cold water basin of each cell.

1. Cell #1 will ship with the flume box factory installed. Position Cell #1 on tower support and bolt in place.

2. Wipe down the flanges on the end of the flume box. Apply a layer of 1/8” x 1” butyl sealer tape around the faceof the flange over the centerline of the holes. Do not overlap or stretch too thinly at the corners. When it isnecessary to splice the sealer, be sure to press the two ends together to form a smooth, continuous strip.Apply a second layer of sealer tape over the first layer following the same procedure. Refer to Figure 8.

3. Position Cell #2 on the tower supports and wipe down the surface adjacent to the opening to remove any dirtor moisture.

4. Using drift pins to assure alignment, draw Cell #2 tight against the flume box.

5. As illustrated in Figure 9, insert tappers in each hole and tighten.

INSTALLATION OF FAN GUARDSeries 3000 Cooling Towers

Due to height limitations on truck shipments, the fan guard may ship unmounted. Models 3240C through 3379Chave a one-piece fan guard. Models 31132C through 31301C have a four-piece fan guard. The supports for the fanguard should be joined as illustrated in Figure 19, Detail A before securing to the fan cylinder as illustrated inFigure 19, Detail B. The fan guards should be joined together and to the fan guard support as illustrated in Figure19, Detail C before securing to the fan cylinder as illustrated in Figure 19, Detail D.

Fan guards for all other models are shipped in two halves. These halves should be bolted together using fan guardclamps, 3/8” bolts and lock nuts supplied with the unit. Then attach the guard to the unit as illustrated in Figure19, Detail D. Fan guards must be securely in place before the Series 3000 Cooling Tower is placed in operation.

INSTALLATION OF THE OPTIONAL SIDE OUTLET DEPRESSED SUMP BOXSeries 1500 and Series 3000 Cooling Towers

The optional side outlet depressed sump box allows a cooling tower water outlet connection to be piped from under-neath the unit in four possible directions, 90o apart. The piping connection is a bolt circle designed to fit an ASMEClass 150 flat flange with a full-face gasket.

To install the side outlet depressed sump box, follow the steps below:

1. Wipe the edges around the opening in the cold-water basin to remove any dirt or moisture that may have accu-mulated during shipment. Apply a layer of 1/8” x 1” butyl sealer tape around the opening in the basin over thecenterline of the holes. Do not stretch the sealer too thinly or overlap at the corners. When it is necessary tosplice the sealer, be sure to press the two ends together to form a smooth continuous strip. Apply a second layer of sealer tape over the first layer following the same procedure. Refer to Figure 20.

2. Insert the sump box assembly into the opening in the cold water basin and attach it to the basin with 3/8” x 1”bolt and nuts, flat washers, and lock washers as shown in Figure 20, Detail A.

3. Place the suction strainer over the opening.4. For Series 1500 Cooling Towers, the side outlet depressed sump box may need to be attached from underneaththe basin bottom. The sealer tape needs to be positioned between the sump box and the outside basin bottom.

Figure 20

TOP INLET PIPING INSTALLATIONUse the following drawings and notes when installing top inlet piping on FXT and Series 3000 Cooling Towers.

FXT Cooling Towers (Figures 21 and 22)NOTES:1. All piping must be supported external to the tower and restraint provided to ensure no vertical or horizontal movement of the inlet piping. All piping and supports are to be furnished by others, refer to the certified drawing for details on the tower connection size, etc.

2. Inlet piping should rest on the flow divider located 7/8 inch below the top of the water distribution box. The piping that enters the opening must be of proper size (see Detail “A”). Refer to the certified drawing for detailson the tower connection size.

3. Flow control valves are recommended on multi-cell towers to ensure proper water distribution and are to be furnished by others.

4. If BAC vibration isolation rails are furnished, the tower piping must be independently supported, since no provision has been made for the weight of the piping in the selection of the rails.

5. For units installed on vibration isolation rails, flexible connections should be installed in the piping just beforethe tower perimeter.

Series 3000 Cooling Towers (Figures 23 and 24)NOTES:1. All piping shown by dashed lines is to be furnished by others. Refer to the certified unit print for details on thetower.

2. Field piping should be fabricated at the time of unit installation. Pre-fabrication of pipe work is not recommended.

3. Required static pumping head from base of cooling tower is indicated by static lift dimension and piping friction losses.

4. When tower is equipped with safety railing package, inlet piping should be designed to clear the railing. Adjust static lift as required.

5. For units installed on vibration isolation rails, flexible connections should be installed in the piping just beforethe tower perimeter.

6. All piping supports to be designed, furnished, and installed by others.

Single Riser (see Figure 23):7. Supply piping to cooling tower inlet connections may be supported from the tower structure only at the pipe support locations shown. Piping must not be supported by the tower inlet connections. Piping outside the perimeter of the tower must not be supported from the tower.

8. Supply piping supports must be designed to rest on the walls of the hot water distribution basins at locations indicated (see Figure 25, Detail “A”).

9. Maximum diameter of inlet header piping that can be supported by the cooling tower distribution basins is 14 inches.

10. Provide adequate space between cooling tower and riser piping to allow for entry into the cooling tower accessdoors.

Dual Riser (see Figure 24):11. Supply piping to the cooling tower inlet connections must not be supported from the tower.

OPTIONAL FACTORY PRE-WIRED TERMINAL BOX

Series 3000 Cooling TowersBAC offers an optional terminal box with factory pre-wiring for Series 3000 Cooling Towers. When this option isordered, the towers fan motor(s) and vibration cutout switch are wired at the factory (through flexible conduit andthe mechanical equipment support) and terminated on the outside face of the BAC unit in a clearly marked, 304Stainless Steel, NEMA 3R terminal box (see Figure 33 for the exterior location of the box on the tower).

The box includes a cover plate, which once removed reveals an easy-to-follow wiring diagram and modular terminal blocks. Remove the cover plate, and install the collar (ships loose in the tower’s basin) which has pre-punched conduit holes. Wiring from the terminal blocks to the unit controls is sized, provided and installed by others. After the controls are wired, reinstall the cover plate on the terminal box.
