I have a problem (sort of).
I got asked the other day if I would take on a service contract for several supermarkets. I've been doing refrigeration over the years, but not that much supermarket stuff. Anyway, one of the supermarkets has cases not maintaining a cool enough temperature, but to make things worse it's on a multiple compressor pack, which I have to say I haven't done properly before. A single compressor-no problem, but a pack ?
How different is fault finding with these? Right now I'm in half a mind to not take the work on.
