Hello guys, I have had the misfortune to have to look at a big old ice cream, serve over, scoop, display thingy. Unit is prehistoric, originally on R502, but over the years, has had an electrolux condensing unit on R404a nailed in it.
The machine freezes up every couple of days so the ice cream is removed and the machine switched off to thaw out. The previous engineer has told them this is what they have to do.There does not appear to be any form of defrost, no sign at all, no wiring, so I presume the old condensing unit had a timeclock, and/or hot gas setup. I was thinking of putting a timeclock on the comp feed from the t/stat, but as there does not appear to be any defrost heater,or hot gas available, makes me think I would be pissing in the wind a little bit. I know the circulation fans would still run but would it be enough on its own?
Don't have much details on the machine, as far as I can remember it was Italian - COF ?
Any thoughts appreciated
Andy
