Pioneer KWIK-E-VAC Line Set Flushing Kit Installation Simplifier for Mini Split Air Conditioning Systems

Best kept secret! Not a plumber here. Had a friend tell us about this. Used this to install a 12000 btu split system to avoid needing a vacuum and pressure gauge. Worked perfectly! No need to pay a plumber hundreds or buy weird equipment.

Used to charge my new mini-split. No need to pay an HVAC tech to do the job.

Worked great. Watched a couple of youtube videos on use. One challenge is knowing when you've flushed the line. Even though the can is supposed to be enough for a couple of installs, I only had one to worry about, so I used most of the can. Per the instructions, I started with the smaller compressor line off the fitting, let the Kwik E Vac vent into the service port for perhaps 20 to 30 seconds, and then slowly started to thread the small line onto the compressor port; I left it a little loose so I could still hear the escaping gas from the Kwik E Vac can. I didn't tighten it until the escaping gas noticably slowed down, and then I tightened it fully, feeling comfortable I had used most of the can and the line was fully evacuating of air.Was rewarded with a nice, cold airflow from the inside unit the first time I fired it up. Install is in a shed serving as an office. It was in the mid-seventies outside, and I set the unit to 68. It cooled it down very quickly. Tested the heat on a cool morning a few days later, and the unit blew nicely warmed air.This product works, as long as you do your part with properly fitted connections on the coolant lines.

Item arrived as advertised,Thank you.Regards,J.G

This was a lot easier than the idea of buying another pump I was going to use only twice. The last one I bought was years ago for an a/c install, never used it again and gave it away. Because I live and travel and work out of a converted school bus, I am not the kind of person that holds on to things I don't use often. I don't have the room for extra junk. These cans were quite convenient. This was for an install of a mini split unit to my bus, in fact. I couldn't use the whole can simply because the inside unit came pretty much pre-charged with flushing gas. Still, I used about a half of this can and followed the directions. Couldn't have been easier, and my unit works flawlessly. I will be looking for these again especially since several others want me to do their mini split install now.Update 7/11/2021Fortunately for me, I forgot to torque one of the lines on the outside unit and all of the coolant slowly leaked out. First, the inside unit started freezing up, and a few days after that started, it wasn't able to really cool at all. It wasn't until I had time to look at everything that I remembered I never fully torqued the outside connections. Usually when the coolant can leak out like that, that means some air likely got in as well, so I just evacuated out the remaining coolant, vacuumed the system with a 1/3 hp vacuum, and then refilled the coolant (from a 25 lb tank of r410a) according to the service manual.I immediately noticed that the inside unit was blowing FAR cooler than what it did when first installed. Yet, there was absolutely no ice. Everything was perfect. The thing is, I'd bought and installed two mini splits using this stuff on the bus I'm converting to an RV. The second one was still working, but I couldn't help but notice it simply wasn't as cool as the newly repaired unit. I was going to just let it go, but I couldn't. I evacuated the coolant from that system, vacuumed it out as well, and then refilled it too. The difference? When the temperature reached 92 degrees yesterday, I had to turn the air up to 72 because my toes were starting to hurt (I used to always leave it set at 68). My toes hurting says a lot considering I'm a diabetic. I used to schedule my units to switch to 68 degrees around 8 AM and around 9 PM, set to 70 so I won't be too cold. Last night, I had to set it to 73 to not be too cold. It wasn't cooling outside of its range or anything. It just turns out when two units are working at 100% and can truly cool everything down to under 70 degrees, that's a bit chilly.So, I won't try to take any shortcuts when installing or repairing any of these split units. No more flushing kit in a can. I'll stick to good old fashioned vacuuming because had my one unit never leaked everything out, I would have never known these units could have been doing so much better.

The canister will freeze as it discharges the contents. I used this in place of a vacuum pump and it seems to have done it's job. My mini split is running perfectly. Be sure to watch the Youtube video before using this canister.My only dislike is that there is no gauge to check for leaks. I had to use the soap bubble test on my connections.I would use this product again.

I installed two Mini-Split Cost Way heat pumps using this product and have had zero problems after the installation. I didn't have a vacuum pump and didn't want to purchase one for a one time use. This was a perfect alternative.

Have used this twice now installing mini split units and it works great, saves the time and expense of hiring an hvac tech or buying all the professional equipment needed otherwise.
