Cleaning

Any evaporative-type cooling tower must be thoroughly cleaned on a Warningregular basis to minimize the growth of bacteria, including Legionella Pneumophilla, to avoid the risk of sickness or death. Service person-

nel must wear proper personal protective equipment.

Do NOT attempt any service unless the fan motor is locked out.

Operators of evaporative cooling equipment, such as water cooling tow- ers, should follow maintenance programs which will reduce to an absolute minimum the opportunity for bacteriological contamination. Public health service officials have recommended that “good housekeeping” procedures be followed, such as: regular inspections for concentrations of dirt, scale, and algae; periodic flushing and cleaning; and the following of a complete water treatment program including biocidal treatment.

Visual inspection should take place at least once a week during the op- erating season. Periodic flushing and cleaning should be done at least twice a year. Nozzles, louvers, drift eliminators, and easily accessible fill surfaces should be flushed by use of a moderate-pressure water nozzle, being careful not to cause physical damage. A reliable water treatment program should be installed and maintained.
