Trane CenTraVac™ Water-Cooled Chiller CVHF - 1070-1300 - 1062 - 142E / 142L

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

1. Follow all instructions in “Waterbox Removal and Installation,” to remove waterbox covers

2. Work a round nylon or brass bristled brush (attached to a rod) in and out of each of the condenser water tubes to loosen the sludge

- Shut down the chiller once each year to check the items of Exterior

2. Clean and touch-up painted surfaces as needed

3. Repair deteriorated, torn, or missing insulation;

- The replacement schedule for the optional zinc or magnesium anodes can vary greatly with the aggressiveness of the water that is in the system

- Some sites could require anode replacement every two to three months while other sites may require anode replacement every two to three years

1. Trane recommends inspection of anodes for wear sometime within the first several months of the anodes being placed into service

2. If the observed loss of anode material is small, then the interval between subsequent inspections can be lengthened

3. Replace the anode and/ or shorten the inspection interval if the anode has lost 50 percent or more of its original mass

4. If anode depletion occurs very quickly, consult a water treatment specialist to determine if the anode material selected is correct for the application

Failure to follow instructions could result in equipment damage

- Use a non-destructive tube test to inspect the condenser and evaporator tubes

1. It may be desirable to perform tube tests on these components at more frequent intervals depending upon chiller application

2. This is especially true of critical process equipment

3. Ask your Sales account manager for a copy of engineering bulletin (CTV-PRB024*-EN) for clarification of the role of eddy current testing in chiller maintenance by providing information about eddy current technology and heat exchanger tubing;

- Shut down the chiller once each year to check the items for Leak Test Chiller

1. Check purge times and unit performance logs. If warranted, pressure leak test

2. Review oil analysis. If required, submit refrigerant sample for analysis

3. Inspect unit for any signs of refrigerant or oil leakage

4. Check unit for any loose screws on flange, volutes, or casing

Failure to follow safe leak test procedures below could result in death or serious injury or equipment or property-only-damage

Never use an open flame to detect gas leaks. Use a leak test solution for leak testing
