Oil Addition

If the line set you selected is the shaded area of R22 Line, Maximum Rise Chart oil needs to be
added to the compressors. The formula below determines the amount of oil to add to the com-
pressors.
- TSC = Total System Charge (pounds*)
A rule of thumb is to multiply the amount of refrigerant in the system by 2.2% and multiply this
sor nameplate and add the remaining amount to the system.
This means that most system doesn't need additional oil unless the refrigerant charge exceeds
35 pounds.
