NOTICE: 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!

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

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

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

In conjunction with other diagnostics performed by a qualified service technician, oil analyses can provide valuable information on the performance of the chiller to help minimize operating and maintenance costs and maximize its operating life. A valve is installed next to the oil filter for the purpose of obtaining oil samples
