![]() Let me give you a piece of hard won advice – use a flare nut wrench if you can to support as many sides of the nut as you can or worst case use a proper fitting box end wrench. Folks when you go to remove the blead-off / unloader line, it is held on by a compression nut fitting. Note the top two poles are the hot legs coming from the wall. If you are in a multiperson environment, follow lock out procedures. I both cut the breaker and unplug the cord. I use a heavy stove/appliance cord going to a wall outlet. Second, please make sure the power is cut. Why open the floor drain? Because it’s your double check that it is empty. Fully drain the compressor – in other words let all of the air out and open the floor drain. Between my age and interruptions, I find it way too easy to forget things. Gone are the days when I try to keep it all in my head. I took a few photos from different angles to make sure I didn’t forget anything plus I labeled anything that might get turned around. So, when it comes to the repair, it’s a fairly easy swap. ![]() You will need to move your gauge, blow off valve, bleed down line, rear pipe plug and electrical lines over from the old switch to the new one. I removed the cover already but this is what comes in the box. I had problems with the check valve on other compressors so I jumped to conclusions and replaced that first. I did some reading and it turned out there were two likely culprits – either the check valve was leaking air back or the pressure switch was failing. After this got really annoying, I decided it was time to fix it. This meant that the compressor may or may not restart without tripping the 30A breaker and it got worse with time. At the end of the air fill cycle that brings the tank back up to pressure, the switch would shut off but then there wasn’t any bleed down to relieve the pressure on the pump. Failure is a big deal for me because when a compressor goes down in my shop, almost all work stops.Īt any rate, I knew something was going on with my compressor before it stopped running completely. One of the reasons I went with the 2340L5-V was that I kept burning out the little 30 gallon consumer compressors. Yes, it’s held up way better than my consumer air compressors but a buddy’s big Quincy compressor rocks and that is another story.Īt any rate, I use a ton of compressed air for pressurizing my casting tanks and running all kinds of air tools. In hindsight, had I known more about “value” meaning “we made it cheaper”, I would not have made the purchase. About 2-3 years ago I invested in a 60 gallon Ingersoll Rand (IR) 2340L5-V air compressor which is their entry-level “Value Line” of industrial compressors.
