NOTICE
Risk of improper compressor lubrication. Can cause compressor and refrigerant system damage.
Failure to use oil types, viscosities, and quantities recommended by the compressor manufacturer may reduce
compressor life and void the compressor warranty. See Table 12.2 on page96 for the recommended oil for the
system.
• Do not mix polyolester (POE) and mineral based oils.
• Do not mix oils of different viscosities.
Consult your Vertiv sales representative, visit https://www.Vertiv.com/en-us/support/, or contact the compressor
