Trane CenTraVac™ Water-Cooled Chiller CVHE - 230-320 - 289 - 032S / 032S

Perform Annual oil analysis (follow recommendations)

Clean and lubricate oil system as required

Run oil pump and check differential oil pressure

Sign off on the yearly oil system inspection

Equipment Damage! Mixing refrigerants or oils could result in equipment damage including bearing damage, introduction of acids into the chiller, or continuous purge pump-out in high-head/high ambient applications

CenTraVac chillers are manufactured with different refrigerant/oil systems: 1) chillers using R-123 refrigerant and OIL00022 compressor oil, and 2) chillers using R-514A refrigerant and OIL00334/OIL00335 compressor oil

Verify proper refrigerant and oil for your chiller and do NOT mix refrigerants or oils!

Important: Verify proper refrigerant and compressor oil for your chiller before proceeding!

1. After the first six months of accumulated operation or after 1000 hours operation—whichever comes first—it is recommended to change the oil and filter

2. After this oil change, it is recommended to subscribe to the Trane annual oil analysis program rather than automatically change the oil as part of scheduled maintenance

3. Change the oil only if indicated by the oil analysis. Using an oil analysis program will reduce the chiller’s overall lifetime waste oil generation and minimize refrigerant emissions. The analysis determines system moisture content, acid level, and wear metal content of the oil, and can be used as a diagnostic tool. The oil analysis should be performed by a qualified laboratory that is experienced in refrigerant and oil chemistry and in the servicing of Trane® centrifugal chillers

Test appropriate sensors for accuracy

Ensure sensors are properly seated in wells with thermopaste installed

Check evaporator leaving water temperature low temperature cutout setpoint

Condenser high pressure switch check-out

Check adjustment and operation of the inlet guide vane actuator

Sign off on the control circuits inspection

Lubricate the gantries annually

Select the lubricant used for gantries

Select the lubricant used for hinges

Sign off on the lubrication process

- 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;
