Charging and recovering refrigerant from a small appliance requires access to both sides of the system. The manifold gauge set provides a high-side port and a low-side port, so you can connect equipment to the correct side and move refrigerant in and out while you monitor pressures. For charging, you typically introduce refrigerant through the low-side while watching the low-pressure readings; for recovery, the recovery device needs access to both sides to pull refrigerant from the circuit and route it appropriately. Because you must interface with both sides to complete these tasks, the best choice is using both high-side and low-side service connections.
