    I have freed up seized comressors with 5-2-1
    I started a comparison thread last summer and put down all my findings.
    the kickstart came in 2nd place
    Tell Obama he can keep the change

    A "true" 5-2-1 is the way to go.

    CSR U-1 and U-2 are stock items in the trucks.

    The Supco SPP6 was also a favorite for years. The caveat was, that you needed to add a delay-on-break timer to use them.

    The advent of digital thermostats with built-in delay solved that issue.

    A Supco has to cool/reset after use. A true 5-2-1 does not.

    Kickstarts are only two wire. We had a case of them, and rewired them all as three wire before using them.
    Technical incompetence is NOT a sales tool....

    I alway`s change relay with start cap. Do you tear open relay to look at points?
    usually relay destroys cap by sticking

    Glennhvac,

    Johnstone (Gurnee and Niles) and Berkheimer (Arlington Heights and Niles) carry all three sizes of the 5-2-1 kits.

    Note the CSR U3 is specifically sized for 4 and 5 ton SCROLL compressors.

    I also have attached a Bulletin from Copeland listing approved sizes of Start Capacitors for different size Scroll Compressors.

    Hey thanks neighbor. I could not find them on Johnstone site and just started looking around over the weekend. I did see them at Berk catalog last night. Thanks! We have probably crossed paths someplace

    By the way, Johnstone:
