    yea

    Round down!

    51 rounds down to 48 or 4 ton.

    41 rounds down to 36 or 3 ton.

    21 rounds down to 18 or 1.5 ton.

    Easy way to remember Lennox. Last digit is phase

    One addition to Lennox...

    The Mod: HS16-511 as described is in fact a 4 ton, But what I call Heavy 4 ton.  51K being heavy,...you can work with the TXV to go between 4 and 5 ton with no problem and little adjustment.  Althought it is a 10 SEER rated cond, lennox always like's to use TXV which I think is a great Idea...



    PS Jonny Mills, You may be right on the last 2 numbers, but I thinking it reffers to the revision number.  How many times the unit itself has be updated or modified???  I could be wrong...

    The last digit in 511 is the phase.  513 would indicate 3 phase.

    The last two digits in the model # indicate revision and voltage.

    Revision

    Usually a dash- number is the revision number, like G16Q3-75-3 but as was confirmed, the number in the 511 or 513 is the phase.
