π¨ Why is the R-410A cylinder tilted during charging?
R-410A is a blended refrigerant, so it must always be charged in liquid form to maintain the correct refrigerant composition.
When charging a running system:
β
Charge through the low-pressure (suction) side using the proper charging procedure.
β
Do not charge liquid continuously. Introduce it in small intervals by slightly opening and closing the manifold valve, allowing the refrigerant to vaporize before reaching the compressor.
β
Charge the specified refrigerant weight using a weighing scale.
β
Monitor system pressures and operating conditions throughout the charging process.
Following the correct charging method improves cooling performance, protects the compressor, and increases system reliability.
