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

- 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 gantries annually

1. Use ConocoPhillips Gantries MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi-Purpose (blue in color), or equivalent

- Lubricate the hinges annually

1. Use ConocoPhillips MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi- Purpose (blue in color), or equivalent;

- 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

- 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;

Check chiller for normal operation
