Service Tools
R410A is used under higher working pressure, compared to previous refrigerants (R22,R407C).
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 (R22,R407C) can not be used
for products that use new refrigerants.
Be sure to use dedicated tools and devices.
