Monthly Maintenance

  • Inspect general conditions of the cooling tower and clarity of sump water.

  • Check the water level in the cold water basin and adjust if needed.

  • Check the float ball and make-up valve for proper operation.

  • Check the line voltage, motor amperage, and water pressure.

  • Clean Sump Strainers, if installed.

Every 3 Months

  • Lubricate Motor Bearing, (if motor has fitting for greasing. Most motors require no external greasing). Use proper lubricants. Increase frequently, as necessary depending on the conditions of service.

  • Check for obstructed water flow through nozzle orifices. Clean and flush spray nozzles, as required.

  • Check ALL bolts at fan assemblies. Retighten to specified torque. Inspect fan/motor assembly.

  • Meet with water treatment company who is regularly monitoring tower chemical treatment to review records and future treatment recommendations.

Every 6 Months
