I installed a Sporlan TEV today that was adjustable. This particular installation was for an A/C unit, but being most Residential A/C TEVs are not adjustable, I thought it a waste of time to ask the following questions.
My first question is how do you know when a replaceable power head has failed versus a failure in the other components of the TEV, or in other words when do you know for sure that the powerhead is the issue.
My second question is: Sporlan shows in their paperwork that in order to adjust you turn one way for up and one for down, but they don't tell how many turns or fraction of a turn = one degree.
Did I say two? I meant 3 questions. They also showed that they don't allow a Vertical bulb placement. I see vertical placement all of the time and this particular install had no horizontal placement option and the bulb had to be placed after the equalizer tube. Valve held 15 degrees superheat at the coil out of the box even with this misapplication. What was supposed to happen that they don't want a vertical placement and bulb after the equalizer tube?
