Good job Dave. Very neat. Experience has taught me to make separate holes for each suction and liquid line , I also install pvc sleeves....Nuisance call outs on weekends and at midnight because the luquid line has rubbed on the cold room panel
I'm with you on using ridgid copper. Its looks so much better. If ya haven't used the zoom lock tool yet you should give it a try. That thing is so nice. Great video as always .
Good work. Your preference for hard pipe ACR tubing rather than soft copper linesets caught my ear. I find it interesting. I also think your way makes the final piping layout look better than lineset piping. The extra step of having to insulate the suction line is worth it. Your work is good.
sparks a flying when drilling the line-set hole, must have been some hardened metal panel. if you find it chews the hole-saw bits up too fast grab carbide tooth ones(yeah price premium) and slow the speed down some, instead of a few holes they'll make hundreds ;)
Once you get the knack for it Annealing your hard ACR and bending it is easier and faster than cutting it and making an elbow and having to breeze it back on again. And you never ever have to worry about a leak at the two braise points.
Nice professional looking workmanship there Dave. I don’t think the go pro on the hat worked that well to be honest, I couldn’t see half of what you were doing. Regardless, it was still a great video, thanks Nor-Cal!
Nice job Dave, I guess the suction trap is enough since there ain’t much of a height difference, didn’t really need to slope suction after box penetration?
Dave, piping looks great but man if I see an apprentice out there using your technique to find center on their suction line hole he’s going to get plumbed up. You show a lot of good practices and measuring off the side and back of box to find true center might be some good info to throw in there...
some of us just have a good eye, I can generally eye ball a hole 3' distance away from starting point and come up less than 1/2" skewed. granted I've been doing various/many construction fields of work since a young brat, electrical, electronics, computers, automotive and more. yes, I have made my share of mistakes and learned the hard way(and still do) Murphy's law has us all the nuts and teetz LOL. it's how you properly deal with, admit to and correct your mistakes, that makes us better humans :)
@@throttlebottle5906 As can Dave apparently, just not good practices for apprentices or recently turned out Journeymen... with reference points so close from side and back of unit it’s laziness not to grab a tape and get it dead on imo. Plumb level and square is priority when I am working on any project...
Glad you did ACR pipe on this application. A lineset would be difficult to work with there. What do you use to protect the pipe and insulation thru the box hole?
Layout and drill from above, both hanging bolts and pipes. Drill a smaller hole along side suction for liquid line. Takes a little planning and measuring, much better job. Almost impossible to seal piping pentration with liquid and suction in the same hole, super critical in freezer aplication.
Looking Good ! I’ve seen a few of those turbo air condensing units , Looks identical to a heatcraft unit. Re-Badged heatcraft with a different paint job.
Turd herder pipe. It looks like the liquid line is touching or wants to touch the aluminum box on the inside where you made the hole. That could be a failure point, ripe for rubout.
4:45 - Since you can safely assume your walls are plumb, you can use a tape measure to pull the exact center off the walls instead of guessing where the center of the pipe is. That way your copper will be plumb in all directions. 15:18 - Any concerns about scraping the inside of the insulation over the end of that unprotected tubing getting into the pipe?
Very neat job Kung Fu Dave , as long as you don't become Kung Flu Dave innit ! Btw , I was told that the bulb has to be " counterflow " to the suction line , meaning that the capillary tube outlet faces the evap , is there any truth in that ? Cheers Dave , very nice 👌.
Plumber copper is M type. K type copper is just like L type nitrogenized and for refrigeration expect it has a much thicker wall. Have ran lots of K type at Costco's very heavy stuff. You'll also recognize K type because it'll come with an orange plug rather than a white one.
@@adriancervantes19 K type is heavy and in Costco you might have run for glycol system. We ran K Type for VRF system (80 ton system) and depending on the project requirements (client) it can be designed. The Ontario building code says L Type copper minimum is required for plumbing. We have green plug in K type copper and its nitrogenized. I think I saw L Type with orange plug. Depending on local building codes it can vary.
The expansion valve function will be normal when its on its side? I was always told otherwise. Finny I just put 6 of these style coils in..can't stand them. Drains and piping come so low...
I noticed You didn't run your suction on a downhill angle towards the condenser like you usually do. I put ptraps only on 12 ft or higher vertical rises. Am I wrong???
to help with refrigerant oil return to the condenser/compressor. while the system runs there's always some oil loss via vaporization and misting from the compressor into the system, the trap collects that and allows it to be sent back vertically in slugs or to aerate back into a vapor/mist mixed with the refrigerant gas so it carries back vertical. I'm NOT a teacher nor engineer, so my explanations may not always be the best :)
that intro music is total crap............>>>>>> Good job I would of taken shrader valves out while brazing . once bitten twice shy , also did you put sensing bulb up stream or down stream of equaliser ? liked your eye for job neat would be great to hear tech info and why your doing certain things cheers tho nice vid but drop your intro musak jeezus
your lineset size has many factors when sizing, coil manufactures provide you the largest. its professional to size your line set correctly. someday you may learn how to be a refrigeration mechanic. 🤣🤘🤣
@NorCal-refrigeration if you need to down size your evaporator line out maybe you choose a coil that is too big for this room Or a small unit for this evaporator More ever between the evaporator and and compressor you have such a pipe length that is even recommended to take a bigger pipe. Suckers don't die only replace Poor customer 😢
