Re: Using R407c in R22 air con Daikin systems
Normally there will be a slight drop off in performance. If the system has head pressure controls you may need to elevate the working head pressure to improve the performance.
See this link for further details http://www.tecumseh.com/en/canada/li...f%20R407C.ashx
Hope that this might help.Mobile A/C at its best, see avatar.
