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

- 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;

- 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;

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

1. Perform Annual oil analysis (follow recommendations)

2. Clean and lubricate oil system as required

5. Run oil pump and check differential oil pressure;

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

1. Review the purge Installation, Operation, and Maintenance manual and follow maintenance and/or inspection items identified

3. Review overall operation of purge and service as necessary;

- Contact a qualified service organization to determine when to conduct a complete examination of the unit to discern the condition of the compressor and internal components

1. Check the following: chronic air leaks (which can cause acidic conditions in the compressor oil and result in premature bearing wear) 2. Check evaporator water tube leaks (water mixed with the compressor oil can result in bearing pitting, corrosion, or excessive wear)

3. Check condenser water tube leaks (water mixed with the compressor oil can result in bearing pitting, corrosion, or excessive wear);
