Done several of jobs with these Aspen coils where it comes with the sensing bulb dangling in the box with the strap for the technician to mount. I'm curious about its proper mounting location as it seems difficult to mount it correctly to the way most literature states a sensing bulb is to be mounted in relation to the equalizer line.
The manual it comes with makes no mention of the equalizer line. Everything I've read seems to imply you always install the bulb ahead of the equalizer line. On these coils, the equalizer line is literally mounted right beside the last manifold branch on the suction header. So there's not really any decent amount of room to install the bulb upstream of the equalizer line. It seems to install quite nicely on the center section, or with a bit of cutting of the strap it can be wrapped closer to the end of the header and still be upstream of the equalizer line.
If it cannot be installed on this header, it would have to be installed outside of the plenum on the suction line as there's not enough room after the equalizer line and the outlet of the suction line to connect it. Some other techs are installing it outside the plenum after their brazed joint.
I'm curious what you guys would do, or are doing. I'll post a picture from a thread on another forum where someone installed the bulb on the exact exact coil I'm referring too. However, the one in the picture was clearly installed by a buffoon that really had no idea what he was doing.

They leave these triangular shaped metal folds on the top of these coils on each end that are as sharp as a razor (also seen in the above picture). With my hand on top of the coil I naturally pulled my hand back after I was placing it and the sharp edge of this V shape metal sliced into my finger and only wedged in further and deeper as my hand pulled back. Excellent engineering design for getting cut pretty good.
