(it's late but I think that's right) Gotcha

Originally Posted by Lusker absolutely. It works like charging a static plate. Caution though. Add your charge slow and let the frost line mature. Stop charging somewhere between 2 to 5 inches before the comp. Be sure to weigh it in so you can mark the box plate. I'll also suggest a Sporlan CAPT 032s drier and be sure to point the outlet end of the drier down. This will give you a liquid seal on the cap tube.

Hey Powell... yeah, too many UC units with retro juice under my belt with filthy condensers in enclosed areas. I think you have seen at least one Delfield haven't you?? LOL Ace... I like both but you're right about the JB chart. Seems to be a little closer at times.

For some reason I just dont like Supco. I use the JB brand cap tubes. Their conversion chart seems to be pretty good.

Originally Posted by Lusker To adjust the easy way... unplug the evap fan and charge until you get a frost line that stops just before the compressor. Go easy adding refrig and take your time.

I think I know what you're getting at... You're right, sometimes the charts seem to be way off. When this happens to me I just adjust the charge and make sure the info is noted on the box.
