______________________________________________________________________ What if I’m working on a medium temperature commercial cooler and the cap tube is plugged up? Without going through the trouble of replacing the whole cap tube, couldn’t I just replace it with an expansion valve? What if the condenser is located on top of the building. How would I determine which expansion valve to put on?

At the same time, you should replace with a 052 instead of those junk dried filter.

Cap tubes are normally on nominal tonnage coils and are easy to replace. Xenos. The best way to escape a problem is to solve it.
