5.15 Oil level
The oil level should be maintained at mid-point of the sight glass. If an oil regulator is used the
level should be set within the top half of the sight glass.
5.16 Digital system control
Due to the pulsing characteristic of Copeland Scroll Digital compressors superheat control needs
to be performed by qualified solutions in order to assure the stability, reliability and good
performance of the system.
NOTE: For further information about these solutions see Technical Information C7.8.3
"Refrigeration – Controlling Digital Scroll".

During the loaded state, when the Copeland Scroll Digital compressor operates at full capacity,
the power factor is almost the same as with a standard scroll. However, when the scrolls are
unloaded, the power factor is lower.
