Trane CenTraVac™ Water-Cooled Chiller CVHF - 1070-1300 - 1062 - 250E / 250L

Shut down the chiller once each year to check the items of Starter or Adaptive FrequencyTM Drive

Check all connections per manufacturer specifications

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

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

Record all applicable starter or starter component settings

Sign off on the yearly inspection

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)

Verify the accuracy of the evaporator refrigerant temperature sensor (4R10) using an ice water bath

Check 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])

If the sensor is exposed to temperature extremes outside its normal operating range, check its accuracy at six-month intervals

Inspect the condenser tubes for fouling

Clean the condenser tubes 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

- 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;

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

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

This is especially true of critical process equipment

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

Sign off on the tube maintenance

- 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;
