NOTICE: Proper Water Treatment Required! The use of untreated or improperly treated water could result in scaling, erosion, corrosion, algae or slime. Use the services of a qualified water treatment specialist to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

Condenser tube fouling is indicated when the approach temperature (the difference between the condensing refrigerant temperature and the leaving condenser water temperature) is higher than predicted.

If the annual condenser tube inspection indicates that the tubes are fouled, two cleaning methods— mechanical and chemical—can be used to rid the tubes of contaminants. Use the mechanical cleaning method to remove sludge and loose material from smooth-bore tubes.

To clean other types of tubes including internally- enhanced types, consult a qualified service organization for recommendations.

Round nylon or brass bristled brush worked in and out of each of the condenser water tubes to loosen the sludge?

Condenser water tubes thoroughly flushed with clean water?

Scale deposits are best removed by chemical means. Be sure to consult any qualified chemical house in the area (one familiar with the local water supply’s chemical mineral content) for a recommended cleaning solution suitable for the job.

NOTICE: Unit Corrosion Damage! Failure to follow instructions below could result in corrosion damage to the unit and tubes. Follow proper procedures when using corrosive chemicals to clean water side of unit. If unsure, it is recommended that the services of a qualified chemical cleaning firm be used.
