Step 6: Discharging refrigerant
The refrigerant in the system needs to be discharged from the high and low pressure sides of
the system concurrently. If the refrigerant is discharged from one side only, the sealed scroll will

shorter than 12h). Otherwise, a large amount of lubricant will be discharged together with the
refrigerant as well.
