57. How should small appliances with less than three pounds of refrigerant be charged with refrigerant?
Small refrigeration systems with limited refrigerant charges must be vapor charged to prevent liquid slugging and compressor damage. Introducing liquid refrigerant into a small system can easily overfill it and cause irreversible damage to the compressor. Vapor charging allows for controlled refrigerant addition, minimizing the risk of overcharge and protecting the system's components.
