    I was working on an EMI unit today, a little split that someone put in for a communications room, and it had a defective fan cycle control, one of those disc type things non-adjustable.

    Well I decided to put a Penn Johnsob P70 fan cycle on it in place of ordering another disc. Then the old question came up as I was doing it, Is there a schrader in this thing or not ? I did have access to another service valve and eventually that is what I ended up connecting to with a swivel T, I did not try to remove the disc, because they needed the unit to run and if I had blown the refer it would have taken awhile to get it recharged. My question is, shouldn't there be some standard that will tell us whether or not there is a schrader underneath whatever is plugged into the access fitting ?

    I know that most manufacturers won't have a schrader in the HI-cutout control for obvious reasons, but what about the other controls, how do you know if there is or not ? Without calling themand being on hold al day to find out that they don't know either ?.

    I seriously doubt there was a schrader there.

    I look at the replacement part to see if there is a depressor... In your case, with a universal replacement, I go with the swivel tee just as you did and "make it right" if and when the charge is out.

    I agree. Yes there should. It could be as simple as spray painting it a certain color. This color could be used by both the manufacturer and service personal.

    Okay I hereby decree. If you install a shrader fitting spray paint it green.

    There, I changed my signature in my profile. This is an historic occasion.

    Careful, you may be remembered as the man who pioneered schrader valve recognition.

    Because you used a different gauge port, there is now a schrader core in the HP port. Iff'n you'dve removed the old fan switch though, then it wouldnt've been there.
