To calculate the oil required, use the following formula:
Additional Oil Required per Circuit = (Refrigerant Charge * 0.4 - 22)
Enter the refrigerant charge in pounds to determine the oil required in ounces
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 oil types
specified in Table 4.16 below.
• Do not mix polyol ester (POE) and mineral-based oils.
• Do not mix oils of different viscosities.
Consult Vertiv or the compressor manufacturer if questions arise.
