Self-contained (active) recovery equipment is best described by which of the following?
a.It can only be used on appliances holding more than 15 pounds of refrigerant
b.It must always be certified for low-pressure appliances
c.It has its own compressor or pump and can pull refrigerant from an appliance that cannot run
d.It requires the appliance's compressor to be operating to function
解析
Self-contained (active) recovery equipment contains its own compressor or pump, so it can remove refrigerant from an appliance whose compressor is inoperative. This makes it more versatile than passive equipment. It is required whenever the appliance itself cannot help move the refrigerant.
