operation Tower Startup Microorganisms including Legionella bacteria can exist in premise Warning 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. -
Page 4: Operation
operation 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. - Page 5 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.
- Page 6 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.

Page 8: Water Quality And Blowdown
maintenance 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... - Page 9 maintenance 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.
