    Victory Pizza Prep Cooler

    I have been working on a Victory Pizza Prep Cooler, model: VPT-88, circa 2013.

    This cooler has been problematic from day one.

    The other day I was called in for an issue with the "rail" temperature. Upon inspection I discovered an ice ball on the compressor housing. So I went through and check the Evaporators. Defrosted the Base Evaporator with heat gun. Since the rail is cold wall, told the owner to shut the rail off for at least 12 hours. Came back the next day started up the rail. I notice that the compressor housing at the suction entry location began to ice up. I turned the rail switch off and the icing went away (melted). Turn the rail switch on again and same icing. Determined the TEV to the rail is wide open. Ordered in and changed out TEV yesterday. All went well considering it is a Victory. Started the system up and all seemed well. No compressor icing .........BUT......the dome of the compressor felt quite cold.

    I made the mistake of calling Victory/Beverage-Air Tech support this morning. I had two questions for this so called expert. (A) What is the OEM specifcation for the superheat on the Rail, and (B) what is the OEM specifications for Cut-In and Cut-out on the Rail Thermostat.

    This clown could NOT answer either question. He said the superheat was factory default---- whatever that is. I pressed him to give me a number and he wouldn't/couldn't do so. I said would this be a typical 10° TD superheat and he said that it sounded good. Moved on to the Thermostat settings. He told me that the Cut-out for the Cold Wall (Rail) was 44°. At this point I realized that a 5th Grader knew more about this cooler than this clown on the other end did.

    So, what I would like to know is the original questions:
    (A) What is the normal or typical Superheat (ie: 10°F) for the Rail Evaporator..??
    (B) What are the normal Cut-In and Cut-Out thermostat settings for the Rail..??

    Install a EPR Valve in the refrigerator section.
    Shut the rail off at night.

    Basic 8 - 10° SH is fine. Check at the pump for 20 - 40°f SH.

    EPR valve will stabilize the refrigerated section during the off cycle of the cold rail. SH at the pump should still be in range.

    What refrigerant are we dealing with?
