cooling tower fans, and associated auxiliary equipment. This includes ensuring that motors
are properly lubricated and have proper electrical supply and proper rotation.

10. Ensure that the voltage selector switch inside the power panel is switched to the incoming
voltage rating.
11. On machines with free-standing starters, inspect the power panel to ensure that the

cause debris to fall into the contactors. Clean and inspect the contactors if this has
occurred.
