pressure switch settings

[krinst]

is there a site or place to go to get recommended pressure switch settings for medium temperature refrigeration? RHVAC tools used to . Cannot find them there anymore

In the supply houses they usually had a few pt charts, sporland has IT on there, or look at one of there books, they will give you the setting for the different refrigerants, and temp. http://bestsmileys.com/waving/2.gif

Do not mean to sound like a wise-@ss, but the best guide for your settings is your PT Chart. Consult Compressor Mfr specs. It all depends on your particular application, local ambients, etc. Also kind of depends on what switches you're talking about. High / Low psi safety? Fan Cycling?

Try this place

http://www.johnsoncontrols.com/cg/html/refrigeration_controls.htm

They do some good controls.


As for settings ? , the final decision will come down to the design team , for the application.

I might suggest ...www.sporland.com Form 10-135 using the PT card as a service tool.

Sporlan also has a card with troubleshooting tips, line capacity and approx. control settings(Form 10-37-600).

Tyler has a P-T card with there cases, specs, cut-in and cut-out settings + defrost info(sorry no # on it).:(

good jobhttp://hvac-talk.com/vbb/images/icons/icon14.gif, I had one in my wallet for about 8 years (I guess that's why It's famoliar, lol) It was ols and wretched looking, but legible, then my wallet took a turn for the worse and ended up in the washing machine, and that was the end of the old Sporlan PT chart, now i have a tecumseh one in there and it's a bit bigger, my wallet has never been the same!!! hahaha:p

I recognized that as your chart, but rhvactools.com did such a nice neat job of copying it and including it in their website.......

Cheer up, I could have linked to the Alco chart as it has 17 categories as compared to your 12. ;) :D

I would have tossed ya some credit but you let harry's restaraunt burn before you took up the dinner invite again!!!!!!!!!!!!!!!!!!!!!!!!!!!

FYI he said he doubts Sunday but perhaps Monday night but I think he is over estimating how fast it will happen, perhaps next weekend!

FYI, the charts are great, but why on earth can't guys learn them temps and just convert!!!!!!!!!! help me understand!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
