operation 4–Check Geareducer oil for sludge or water by draining off and testing a sample as outlined in the Geareducer User Manual. Check Geareducer oil level at “oil level” mark on the side of the case. Add oil as required. The oil level placard must be adjusted so that its “full”... - 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 operation FREEZING WEATHER OPERATION–During periods of low temperature operation, 35°F to 40°F or below, ice will form on the relatively dry parts of the cooling tower that are in contact with the incoming air. Primarily, this includes the air inlet and adjacent structural framing. Your understanding of cold weather operation will be enhanced if you read “Cooling Towers and Freezing Weather”...

Page 7: Maintenance
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 maintenance FAN MOTOR–Lubricate and maintain each fan motor in accordance with the manufacturer’s instructions.

Page 9: Water Quality And Blowdown
maintenance EXAMPLE: 7000 gpm circulating rate, 15° cooling range. To maintain 4 concentrations, the required blowdown is .38% or .0038 times 7000 gpm which is 26.6 gpm. If tower is operated at 4 concentrations, circulating water will contain four times as much dissolved solid as the make-up water, providing none of the solids form scale or are otherwise removed from the system. - Page 10 maintenance MAINTENANCE OF FILL PERFORMANCE Water must be kept clean by treatment, screening, or filtering to Warning avoid the possibility of fill clogging and loss of thermal performance. Potential Causes of Fill Clogging: • Suspended materials—Debris, etc. • Scale—Can be sulfates, silicates, carbonates, or oxides. Scaling effects can be accentuated by suspended solids.
