That insulation that comes with the TXV is for the foolhardy said the knuckleheaded airhead as he pitched it in the trash along with the service manuals. I don't know why manufactures have to be so wasteful all the time? Just more trash I have to clean up, he mutters under his breath.

    I save those TXV insulation covers and sell it to someone who really needs one. LOL . A fine point here, the TXV thermal bulb is upside down , the same applies to temp control sensing bulbs.

    The air handler is actually horizontal, Terry. These computers think they know best and this one wasn't having a horizontal airhandler. It prefers vertical.

    Harvey, that poor TXV is probably hunting all over the map.  Don't you hate that?

    Manuals are just so when you kneel down you dont dirty the your clean pants. :)

    Probably a novice question, however why dont they come strapped and insulated from the manufacture?

    I thought the pages in the manuals were for ripping out, soaking in paint thinner, and lighting them afire. Then throwing them into the combustion chamber to light the fuel when it won't auto light. Emergency igniters.

    The manufacturer may not insulate the feeler bulb at the evaporator exit because the ambient surroundings will not have an effect on the target superheat. If the bulb is mounted outside the coil enclosure then insulation is critical.

    I am not familiar with manufacturers who do not mount the bulb. If you need to do this, make sure it is in either the ten o'clock or the two o'clock position on the vapor line.
