Additional Oil Requirements for Scroll and Digital-scroll Compressors
See Table 5.8 below, for the amount required for various system charge levels.
After the system has been fully charged with refrigerant, use a hand pump to add the additional oil at the
suction side of the system while the system is running.
The amount of oil added by field service must be recorded on the tag marked "Oil Added Field Service
Record," attached to each compressor. The date of oil addition must be included as well.
