Before opening a high-pressure appliance, refrigerant must be recovered to what level for a system with a functioning compressor (using recovery equipment manufactured after Nov 15, 1993)?
Answer: 10 inches of mercury vacuum
High-pressure appliances with a working compressor must be evacuated to 10 inches of mercury vacuum with post-1993 recovery equipment.
What is the required evacuation level for a high-pressure appliance normally containing 200 pounds or more of refrigerant if the compressor is not operating?
Answer: 15 inches Hg vacuum
Large high-pressure appliances (200+ lbs) with a non-operating compressor must be evacuated to 15 inches of mercury vacuum.
A self-contained recovery device for high-pressure refrigerant uses its own what to remove refrigerant?
Answer: Its own compressor or pump
Self-contained recovery equipment has its own means (compressor/pump) to draw refrigerant without relying on the appliance.
Which leak detection method is most commonly used for high-pressure refrigerant systems?
Answer: Electronic leak detector
Electronic leak detectors are widely used and sensitive for finding leaks in high-pressure systems.
