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

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.

Demasiado bueno❤️‍🔥

Purchased this to install a pre-charged 9000BTU Della Mini Split for our Master Bedroom. (simple install by the way) I was tempted to buy an evac pump kit because I needed to upgrade to a 25-foot line to reach the outdoor unit. But then I came across this product. I flushed the lines according to the video that was available by scanning the QR code on the box. It was simple to do. I am getting 115-degree air on the heat and 48-degree air on cool, which is amazing for a nonprofessional install. I HIGHLY recommend this for the DIY install. And the Della Unit is awesome and very quiet. Hope this helps.

Flush air out and worked very well.

It seemed fine. The valve and hose I got seemed much nicer than what was shown on the amazon page for it and may have been improved to solve the problem others reported here in the reviews. I used this to help find leaks in a system I installed but had not yet started up. One of the 3 line sets showed a leak during a vacuum test and I used this item to pressurize the line set and I put soapy water on the fittings to try to find the leak. It didn't work right away but after tightening a couple of the flare nuts the bad one started bubbling and I knew that was the leaker. In hindsight I could have just redone each flare and retested but it ended up being the last flare I suspected. If you're DIYing a mini split buy the vac, the manifold set, and the Yellowjacket flaring tool. The cheaper torque wrench seems to have been a waste of time but the rest of it is invaluable.

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.

Must have for mini split installation no tech to call

Worked perfectly on my Della mini split install. Make sure you tighten the can valve all the way to prevent leakage. Would purchase again.
