Trane CenTraVac™ Water-Cooled Chiller CVHF - 1070-1300 - 1062 - 210L / 210L

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

2. Test appropriate sensors for accuracy

3. Ensure sensors are properly seated in wells with thermopaste installed

4. Check evaporator leaving water temperature low temperature cutout setpoint

5. Condenser high pressure switch check-out

6. Check adjustment and operation of the inlet guide vane actuator;

- 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 Starter or Adaptive FrequencyTM Drive

2. Check all connections per manufacturer specifications

3. Follow all manufacturer recommendations for starter or Adaptive FrequencyTM Drive (AFD) maintenance

4. Inspect/clean/service the AFD cooling system (water- or air-cooled AFD)

5. Record all applicable starter or starter component settings;

- Check the chiller’s evaporator and condenser pressures, oil tank pressure, differential oil pressure, and discharge oil pressure

- Compare the readings with the values provided in the general maintenance

- Check the oil level in the chiller oil sump using the two sight glasses provided in the oil sump head. When the unit is operating, the oil level should be visible in the lower sight glass

- Complete logs on a daily basis.
