A small grocery store(owned by people from a foreign country) bought 3-12 foot used sections and they want me to put them together and get a condensing unit for them. I told them I need a model number so I can find the installation manual for them so I can install these as correctly as I am able. It looks like 2 of the sections were piped together and the third was physically connected but not the refrigeration piping. The two sections that were piped together have the exit pipes coming out of the top of the unit and the third section has it's own set of pipes coming out of the top. I apologize for my ignorance, but I don't have a whole lot of experience with this type of equipment. On the wiring diagrams all I can find is "2500 series". I am not sure how old these sections are but they look like they may have been stored for a while, because some critter stored his nuts in one of the bigger holes in the side of the sections. The txvs that I see are R22 and the one I can see completely is "EGVE 1-1/2". The owner also says they are meat cases, but I don't know if that is what they were or what he wants them to be. I have to go back there next week, they will be moving them into the store. I also need to see if these people bought these units without knowing what they were or if they have more info.
Is there a location that I could not see where I can find the model number of these units? If I could get the manual I could determine whether I can pipe the units into one condenser or whether the three sections need to have two condensers. Again, sorry for my ignorance on this.
