Trane CenTraVac™ Water-Cooled Chiller CVHE - 360-500 - 455 - 050L / 080L

- For R-123 chillers, perform the annual maintenance procedures referred to in Operation and Maintenance Guide: EarthWise Purge System with Tracer AdaptiView Control for Water-Cooled CenTraVac Chillers with R-123 Refrigerant (PRGF- SVX01*-EN). For R-514A chillers, perform the annual maintenance procedures referred to in Operation and Maintenance Guide: Purge System with Tracer AdaptiView Control for Water-Cooled CenTraVac Chillers with R-514A Refrigerant (PRGG-SVX001*-EN)

- Use an ice water bath to verify the accuracy of the evaporator refrigerant temperature sensor (4R10). If the sensor is exposed to temperature extremes outside its normal operating range (0°F to 90°F [-17.8°C to 32.2°C]), check its accuracy at six-month intervals

- Inspect the condenser tubes for fouling; clean if necessary

- Inspect and clean the ifm efector® flow detection sensors. Use Scotch-Brite® or other non-abrasive material to clean scale; do NOT use steel wool, which could cause the probe to rust

- Submit a sample of the compressor oil to a Trane- qualified laboratory for comprehensive analysis

- Measure the compressor motor winding resistance to ground; a qualified service technician should conduct this check to ensure that the findings are properly interpreted. Contact a qualified service organization to leak-test the chiller; this procedure is especially important if the system requires frequent purging;

- Lubricate the vane control linkage bearings, ball joints, and pivot points

- Lubricate vane operator tang O- rings

- Lubricate the oil filter shutoff valve O-rings;

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

1. Inspect for fouling and scaling in tubes

2. Check operation of condenser water flow sensing device

3. Factory recommendation to eddy current test tubes every three years;

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

1. Inspect for fouling and scaling in tubes

2. Check operation of evaporator water flow sensing device

3. Factory recommendation to eddy current test tubes every three years;

- 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;
