If you would read ANY trade book, this is NOT why the bottom
of the tube is not used. Please read a trade/tech. book.

That brings up a good question. Some of the guys I work with insist
on mounting it on a horizontal line, offset 45 degrees, and downstream
of the pressure tap.... unless the manufacturer specifies otherwise.
Others mount it vertically upstream and say there's no difference. I
side with the first group. I cleaned and re-insulated/taped the bulb.

comments?

Yup... horizontal at 10 or 2....the bulb should have 2 lines coming out of
it... a real short one crimped off, and a long one that goes to the TXV...
its preferable to have the long one on top. BTW... there is supposed to be
metal to metal contact between the bulb and the suction line where it comes
out of the evap coil, with insulation wrapped around the whole mess.

10 or 2 is a little boyond the 45 degree point. I'll put it there and
see if it makes a diff. I didn't know about the long one being on
top. I'll check that too. I've always zip tied them to the line to
make sure there is not gap between the two. And yes, always insulated
and taped until it looks like a snake after a big meal.

Thanks for the info. I probably won't be until this weekend that I
get back over there. I'll post the results.

Zip ties??? Try a copper or brass strap with screws

Do you suggest to screw it to the copper line? <g>
