very nice work......just have one question. do you guys use clear pvc primer. i always afraid to use it b/c i think the inspector will question whether it was use or not. it makes the job look so much cleaner.
the disconnect is from the original condenser that sat there...no one knows where the electrician went or when he is coming back...I hope he does not hack it all up i can just imagine 15' whips instead of nice hard conduit...or worse yet have them screwed to the condensers
No substitute for hard pipe and unistrut. I do not use linesets anymore and this job is a perfect representation of why. Hope yall did a good leak check on all those joints! One more thing, that must be 410A, did yall purge with nitrogen while brazing? I believe its more crucial with POE oil.Our install guys never do but most of the service guys do.
nitrogen purge...huh? lol I asked them a wile back about it..they just gave me a goofy look. they pressurize with nitrogen to 100lbs then check it after 15 min. If there is a tiny leak usually i find it at start up when i call and ask "did u pressurize this?" They take pride in there work that is for sure.
i didnt mean leak check with nitrogen, i meant "purge" while you were brazing to eliminate oxidization inside the piping. Our install guys give me the same goofy look or they tell me how they have done this for years and its been ok without it! Reguardless if it works without it, its a good habit to get into. And if those units were 410A they should pressurize with a lot more than 100 psig for leak checking, more like 350-400 psig. It probably won't matter but it wouldnt hurt!
