Bending the lineset tubing AFTER the installation

Member Posts: 2
Hello All,
I have a Fujitsu single zone heat pump that’s been up and running for a several months. For appearance reasons I’d like to clean up some of the sweeping bends in the lineset by turning them into tight 90s. I’d use a tubing bender for this. My question is this - is it permissible to bend the vapor and liquid pipes while they’re charged with refrigerant and/or pressurized?
Thank you.

As long as you don’t kink them.0

and be careful not to try to ben sharper than the minimum bend radius for that pipe size --even with a tubing bender. Typically 5 times the pipe outside diameter.pecmsg said:As long as you don’t kink them.

I wouldn’t try it. One end of the tubing has to be free to move while using the bender. Making a tighter radius means that the straight run coming out of the bend is gonna have to be able to increase in length. If it’s locked by the next bend or the termination, how can that happen?Bob Boan
You can choose to do what you want, but you cannot choose the consequences.1 -
I wouldn't try it. You probably won't get the results you want0

If you do attempt it, take video and post it. And no cursing.0

So the line set is exposed on the ceiling?
Can you take pictures?0 -
It'd have to be a pretty big wobble in the long run of pipe to give you enough length to tighten a sweep into a ninety. I'm guessing (from the image in my head, mind you) that you'll need to find at least 2-3 inches for each bend. It doesn't sound like much, but it's absolutely necessary. There is also a capacity reduction that is related to the number of bends. It doesn't sound like it'll be significant, but it's something to think about.0
