Why is it likely for recovery and recycling machines to overheat when drawing a deep vacuum?

• because a deep vacuum causes high head pressure

• because refrigerant is needed to cool the compressor

• because the refrigerant oil has evaporated

• a recovery and recycling machine would not overheat when drawing a deep vacuum

After removing refrigerant from a system, the refrigerant

• may be recycled and sold to another customer

• may be reused in the same system, or in another system owned by the same person

• may not be reused

• must be reclaimed
