The pressure to charge an air conditioning unit with R407C refrigerant typically ranges from 100 to 200 psi on the low side and 250 to 400 psi on the high side, depending on the ambient temperature and the specific system design. It's essential to refer to the manufacturer's specifications for the exact pressure requirements and to ensure proper charging procedures are followed. Always use appropriate safety precautions when handling refrigerants.

How do you charge refrigerant gas in a compressor of a split ac unit?

To charge refrigerant gas in a split AC unit, first ensure the system is off and locate the service valves on the outdoor unit. Connect a refrigerant gauge manifold to the low-pressure side, then attach the refrigerant canister to the high-pressure side. Open the service valves and allow refrigerant to flow into the system, monitoring the gauges to maintain the proper pressure levels. Once the desired charge is achieved, close the valves, disconnect the gauges, and run the system to check for proper operation.
