I currently have taken over for someone who lets say was kind of a hack. I have a 401a(MP39) system with dual evap and txv's. I found the system way overcharged and txv's have been tunned almost all the way in. Is there a way to get the txv's close to factory setting by counting the turns and set them to so many turns? This system has a water cooled condenser with remote condensing unit. By the way it is a small service deli unit. If I cant figure out how to get the txv's close to factory I will probably end up replacing both txv's and adding pressure tap's after each evap. The unit only has to make it for two more months and the restaurant is shutting down permanenty. So I really don't want to install new TXV's on a piece of equipment that is going away.
