• 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 p.448
