- Characteristics of new refrigerant r 410a 1 performance almost the same performance as r 22 and r 407c 2 pressure working pressure is approx 1 times more than r 22 and r 407c 3 refrigerant composition few problems in composition control since it is a quasi azeotropic mixture refrigerant 383

- Copper tube material and thickness 386
- O soft annealed h hard drawn 386
- R 410a is used under higher working pressure compared to previous refrigerants r 22 r 407c furthermore the refrigerating machine oil has been changed from suniso oil to ether oil and if oil mixing is occurred sludge results in the refrigerants and causes other problems therefore gauge manifolds and charge hoses that are used with a previous refrigerant r 22 r 407c can not be used for products that use new refrigerants be sure to use dedicated tools and devices 386
- Service tools 386
- Tool compatibility 386
- Conventional flaring tools can be used when the work process is changed change of work process previously a pipe extension margin of 0 to 0 mm was provided for flaring for r 410a air conditioners perform pipe flaring with a pipe extension margin of 1 to 1 mm for clutch type only conventional tool with pipe extension margin adjustment can be used 387
