A cooling tower is warm, wet, and aerated — ideal conditions for Legionella. Water treatment is therefore a public health control before it is a maintenance task, and it is also what protects the chiller from scale and corrosion that quietly destroy efficiency.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Biological growth with genuine outbreak potential, scale that raises condenser approach temperature and chiller energy use, and corrosion damage that shortens the tower's life.
Monthly at minimum for chemistry, with more frequent checks in warm weather. Follow your written water management plan — for many buildings ASHRAE 188 makes having one mandatory.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
