gage set hose on backwards
I installed my first mini split it did not go as planned.
I did a nitrogen purge and then a pressure test at about 25 psi.. I then vacuumed the line set and indoor unit for several hours. I then released the refrigerant into the lineset , opening both the high and low side valves,and all seemed to be well. When I removed the gage set hose I discovered that it was on backwards and so the schrader valve was not depressed, meaning that the lineset had not been evacuated. When I discovered this I did the pump down procedure for 30 minutes, closed the high and low side valves , and vacuumed the lines for 15 minutes and then re opened the high and low side valves. Am I completely screwed? Did the nitrogen in the lines get into the outdoor unit to raise havoc? The unit seems to be functioning ok. A very small amount of the r410a refrigerant escaped while I was messing around with it. Last edited by bill498326; 04-29-12 at 05:43 AM.. |
