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.
• Do not mix polyolester (POE) and mineral-based oils.
• Do not mix oils of different viscosities.
• Consult your local sales representative, Vertiv™ product support at 1-800-543-2778, or
the compressor manufacturer if questions arise.
