Hi All,
Anybody have any experience repairing GFL Deep Freezer (Ultra Low) -85C Model 6485?
Now I'm repairing this Freezer,but someone already worked on that and not successful until the user called and asked me to help. I need some information like charge data for 1st and 2nd stages, and I also found there is no oil separator on the system, is it originally designed from manufacture?Please help me, for anyone who have known or experience with this ULT?

Thank you,

Asep
