I'm wondering if anyone can give me some insight on these units? I had a service call on one today and there was no literature what so ever. I kept getting the code n1 and I can't get a hold of their tech support. If someone knows about these stulz units, that would be great! The unit is charged with R-134a and the operating characteristics were as follows:
Head Pressure: 140 PSIG, Suction Pressure: 25 PSIG
Suction Line Temp: 78 F
Liquid Line Temp: 82 F before the drier and 70 F after the drier
There is definitely a blockage in the drier and this is causing a slight restriction in the evap. I would love to know what the alarm codes mean! any help would be much appreciated!
