    Carriers with different charges?

    Working on a small strip mall with 3 Carrier 48TCD pack units. Identical model numerals on the plates but the plates have different charges. One is 6lbs 2ozs and the other is 5lbs 6ozs. No visible metering device so I'm "assuming" (dangerous) multiple fixes orifces coming off the header. Any insights from more the experienced?

    48TCD what ?


    Why is a fixed orifice header " dangerous" ?

    Their charges are diifferent because they are each a different capacity or some have micro channel coils and some dont.

    The entire model #s ?

    assuming=dangerous


    the entire model number will let you know what features are different between the units
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    12 oz isn't going to be the difference between the 3 and 4 ton units.

    The 48TCD**04 (3 ton unit) holds 5 lbs 6 oz.

    The 48TCD**05 (4 ton unit) holds 8 lbs 5 oz.

    Why one is labeled 6 lbs 2 oz is beyond me.

    As the others have said, post the full model numbers of each unit and I might be able to find something that list this specific charge.

    There was a service bulletin about the wrong charge on some 48TC units, but I think it was the 6 ton model.

    Full model - 48tcda04a1a5a0a0a0

    And yes - I meant that assuming is dangerous. Sorry my autocorrect went nuts in the first post too.

    I could not find anything that showed why one charge is 5lb 6oz, and the other is 6lbs 2oz.

    In fact I read the product manual wrong, and it list the 3 ton unit as 5.6lbs (5lbs 10oz), not 5lbs 6oz.

    So neither one is exactly like what is listed in the Product data manual.

    It shouldn't really matter what the nameplate says, as the unit should be charged to the charging chart that came with the unit.

    The charge listed on the name plate is only to get you close, if you are weighing in the charge.

    I've seen the 4 tonners ranging fro 5 lbs 6 oz to 5 lbs 10 oz , I've been to the factory I would not rule out a fat finger fiasco.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.
