Refrigerant Oil - Hitachi RCUE40AG2 Service Manual

Maintenance

6.6.2. Refrigerant oil

Freol UX300 of Japan Energy is used as a refrigerant oil due to its high compatibility with R407C. Other
refrigerant oil cannot be used, therefore, pay attention not to be mixed with others at maintenance. The
hygroscopicity is the same as a conventional Icematic SW220HT of Castrol, therefore, moisture maintenance is
not changed. (Icematic SW220HT as well as Ferreol UX300 are ester series refrigerant oil, therefore, open to the
ambient air as short as possible)
