    I don't know really. Coworker said 1/8x1/4 mile according to his odometer haha. I have not seen it all yet we are on a lower level. Had a 45ft JLG about full stretch to set the contents of our trucks on it.

    don't you just love when the flames burn off the wiring schematic?
    "Better tell the sandman to stay away, because we're gonna be workin on this one all night."

    "Dude, you need more than 2 wires to a condenser to run a 2 stage heatpump."

    "Just get it done son."

    Dad adjusted

    Would be glad to have the flame roasted schematic instead of the massive wiring harness and all the wiring within a 1 foot radius around the two flame throwing transformers that is destroyed.

    What's your technique for setting that compressor in place? I have 8 CSHAs to replace on a rooftop and was denied a crane... I have a 40' man lift to get them on the roof but from there is looks like it might be pure muscle.

    Here is 3 ways:
    1. He-man that thing in there
    2. A couple 2x4s making two ramps, roll it up into it.
    3. Get straps or chains and go over the top of the unit and hook on the frame on the other side. I try to have it just long enough that a loop of the strap just barely hangs over by the electrical panel. Then I hook a come a long/chain fall/chain hoist to it and lift it in there.

    Wiring harness in return section caught on fire. Also note the high efficiency filters.

    If the building manager will allow it, we use a Genie Duct Jack to get the compressor up to the level of the unit. Then there is less He-Man stuff to do to get it into place. But you have to have a crane or a boom truck to get the duct jack to the roof. We use this technique when the RTU is too far from the edge to use a crane.

    If the pic is worth a hoot we also have a hydraulic cart similar to C that is awesome for heavy lifting. When the flat plate is oiled 06Es will glide off. But... He has no crane.

    Also if it is a flat roof. A engine hoist can be brought onto a roof in manageable pieces. We turned the boom around on ours and counterweight the base. It works okay not the safest way if you don't have enough counterweight.
