It is up and running. Hopefully I won't be back in this thread a few months or year down the line asking why my heat pump doesn't work anymore. Big electrical savings of over 50%. Over conventional wall heating that barely heated a room. I run this thing 24/7 and 72 degree for one month...

Thanks all for the advice. Started my triple evac today on all 3 service ports. Isolated them from each other. Was able to pull vacuum and hold under 500 microns. I did isolated pump and micron guage. Got down to 50 microns. But the moment I valve off thr micron it shoots up to 500...

The manual didn't say what the min and max pressure for the nitrogen test was. I just chatted with senville. They recommending 300 to 450 psi. Everything I read online say to do it at 300 or it can cause some damage. I double checked my micron gauge this morning. It risen up to 14k...

I think I may have gotten oil or water vapor in the lines Just checked the gauge after 24 hours sitting and it sits at 9k to 11k microns. If their was a leak I assuming after 24 hours it should be reading atmosphere by now. I will do a triple evac this weekend and more testing of the lines...

Welp...I can't pull a vacuum. I get down to 150 microns and it rises up to around 3720 3920 and sits three. Hoovers around that area for about 15 minutes since I been monitoring. I pressured tested around 225 psi and it didn't leak. Held for over 30 minutes. Did bubble test on all...

Thx all. I am nearly done installing this. But I am stuck on the damn flares. I got the 45 degree flare tool from Wostore on amazon. The instructions aren't very good. If i tightened until I hear the click, the flare is completely flat. Are you suppose to tighten these things till you hear...

Question about the flare nut. Its saying the nut size is 3/4 (on the nut itself). But the pipe is 1/2 on a 18k head unit. A 9k unit is 3/8 for the nut, but the pipe is 1/4. Does that sound about right? Also it came with some kind of 3/4 to 3/8 flare nut reducer for the 18k. Do you just...

Question. Can I turn on the compressor by giving it power without linesets? I want to test the noise and to see how much wobble it's going to do to my makeshift platform.

OK, but what about the leaking vacuum pump? Is that normal? I'll get a micron gauge to see where the pump is actually get it down to.

Welp, never started this project until now. Ran into a situation already. I wanted to test my gauges, hoses and pumps for leaks before starting. I believe my vacuum pump connection is causing a leak. I see a rise in pressure after I get it pumped down to -1 bar. Basically goes straight back...

Thanks, that makes more sense. I check other mini split companies that are from midea, and they all have the same value. Pioneer, Cooper and Hunter, etc. Then I checked Gree and they have it at 500 microns. Probably some kinda typo on Midea or they have some new pumps that the west don't...

I ordered myself the Senville 27k BTU 2 heads. But then today started going over the manual to prepare myself for when it came. I got to this part in the manual and wondering if it's wrong or are they crazy? I work in a Semi Conductor fab as a Maintenance technician and we often deal with...

The senville has an online store that you can order parts from. I am actually leaning towards them. And yes, none of these warranties include labor. So you will have to have some hvac tech come and troubleshoot before you can get your parts replaced. The n2 tank I seen at amazon is 375...

I am looking at 9k+18k on a 27k condenser setup that I will add in a 9k later in the future. Looking at prices, its 2400 (sensville), 3300 (mr cool), and 3100 (Cooper). However here's where things get ineresting. For warranty, its going to cost me 500-1000 more to have pressure and vacuum...
