Record results in the equipment history log.

Check manufacturer’s specifications for the maximum number of plugged tubes.

Allow only qualified personnel to do maintenance work on this equipment.

Test system for proper pH, total amount of dissolved solids, conductivity, scale and corrosion inhibitors.

Test supply water for base conditions.

Monitor and test corrosion coupons as applicable.

MAINTENANCE TASK DESCRIPTION:

1. Water treatment for the condenser water system.

SPECIAL INSTRUCTIONS:

1. Chemicals must comply with the Environmental Protection Agency

(EPA) regulations and handled in accordance with occupational safety requirements. Employ personal protection against corrosive or hazardous treatment chemicals as appropriate.

2. Be familiar with the Material Safety Data Sheets of any chemicals used in the water treatment program.

3. Water treatment specialists must be properly trained.

4. Water treatment must be based on proven standard engineering practices.

5. Follow treatment as directed by manufacturer or water treatment company.

6. Maintenance includes chemicals, chemical feeding, maintaining proper water conditions, controlling bleed off, protecting idle equipment, and record-keeping.

7. Select water treatment methods which protect the life of equipment, maximize heat transfer, and minimize scale, corrosion, solid matter buildup, algae, fungi, biological growth, and water usage. Alternate biocides. Changes to higher dosage levels may be required to control growth.

8. Ensure chemicals are properly stored, test equipment clean, and that chemicals have not passed expiration date.

9. Special attention must be paid to wooden towers and solar heating systems which can be more difficult to properly maintain.

10. Physical inspections of towers and piping systems are to be made to determine water treatment effectiveness.

11. Maintain records and test results.

12. All tests shall conform to the manufacturer's test procedures and standard values.
