Cooling Tower Checklist

The document provides a checklist for cooling tower maintenance with inspection and cleaning frequencies. It lists components to check daily, weekly, monthly, and annually including the fan motor, suction screen, water samples, makeup water, vibration, structure, belts, lubrication, motor supports, drift eliminators, and motor condition. A second table outlines additional monthly, quarterly, and six-month procedures such as inspecting general conditions, water levels, float balls, line voltage, and cleaning sump strainers and spray nozzles. The overall goal is to ensure proper operation, safety systems, and prevent equipment issues through regular visual checks and cleaning.
