hi have to gas a carpigiani ice cream machine fitted in an ice cream van,I no very little about this but can stick a drop of gas in to get it freezing again.
It used to run on 502 but have been advised that 408 is the replacement gas? it has a sandon compressor which seems to squeal a lot when you be using it for a long time?
any hints any one as ti what would make compressor squeal and how much gas to put in?
I can get it to freeze back to compressor with out clearing the site glass but am wondering is ther not enough/to much gas in the system and would this make it squeal,many thanks for any info
