If passive recovery is used on a small appliance fitted with a capillary tube as a metering device with a non-operating compressor, the recovery should be made through what means?

Official USCG Answer & Rule Citation

Correct Answer: Option C — recovery from both the high and low sides

Small appliances equipped with a restrictive capillary tube present a continuous internal barrier to vapor flow when non-operating. Consequently, EPA regulations mandate active or passive refrigerant recovery from both high and low sides.
