    It was 83 deg. out during start up. Ran in june when it was low 90's. Tripping w/ 77 deg. o.a. Maybe the cond. coil was dirtier than I thought.

    The suction pressure is at its lowest at the compressor inlet due to press. drop thru piping, which will cause first signs of frost when suction temp. gets less than 32 deg.

    The samsung units are wired different than the Mitsu. or sanyo. I believe you run (5) 14 guage conductors between the indoor & outdoor units, w/ 240 power(2 hots & ground from breaker). No neutral.

    Looks like it used to be a school, fire escape was code for kids in area, but now it's a condo building and they can do this. Still shouldn't be allowed. Could have saved a life.

    I agree Jay, but I don't bother removing shreader cores on anything under 2 tons. As long as I have access to high & low sides. It's usually down to 150 microns when I get back from break.

    Even if you had the right g.p.m. thru the coil, there's no way your going to get 15 tons of cooling with the supply & return backwards (no counter flow). I bet your air side t.d. is less than 10 deg....

    Then I would guess the tech. was not reading the suction line temp. accurately. Maybe using an infrared instead of a thermocouple. I'd say it's good to go.
