Thought I would give you an update. I did the recharge last Friday, I followed the procedures and it went perfect. The scale was the key, getting the weight exact was a great feeling. The output is blowing 49 degrees at it's lowest setting though, didn't know if that's a blessing or...

I can't thank you enough for the valuable information. I really really appreciate it. I tried the digital fish scale - it didn't work - it kept wanting to hold on the weight and stop. So I ordered a refrigerant digital scale, it will be here thursday. In the meanwhile, I just vacuumed and...

So on this setup, it's the same idea except I don't have to unhook anything. I'll still shut off the low side to hold in the vacuum - purge the air from the line - open the low side valve and bring in most of it (slowly) with the unit off. Once I'm close, I turn on the until and measure the...

I've actually got a 4 hose manifold, so it should be easier

Plants are not in any jeopardy, I dragged my portable in there so they are staying cool for however long I need. I only saw some refrigerant oil on the initial leak that I found with a leak detector I bought. I also didn't find any leaks with that detector after I fixed it so I'm thinking I...

It doesn't have a micron gauge, just a compound gauge. What I meant by "drop" was, I shut off the vacuum and line and left the gauge on overnight. Here was the readings: Obviously not as accurate as a micron gauge but it seems to show a slight drop. I have a digital hanging scale that...

Well, I'm certain I have a leak. I held the vacuum overnight on the manifold and got a small drop. This is probably because I don't have a $150 torque wrench....dammit. So I guess there is a possibility that I either under or over tightened the fitting. I'm thinking I could get some nitrogen...

Thanks again for your continued advice - I really appreciate it. I don't have a digital micron gauge but will look for one, and I need a scale ....

My grow area is rigged with environmental control that I monitor from remote, I have a temperature sensor I could stick on the output to monitor the temp. Seems like a good way to double check the refill. I have it on a vacuum, just need a scale - a cheap one since I will only be using it...

So I could do this on a complete refill? I assume I would have to still weigh it and monitor the temperature as I get close to the weight. I didn't see a mode to put it in, so I'll do high cool - I can remotely monitor the temperature as I add the freon. Thank you for your help!

Yeah - I was totally adding this wrong. Thank you for being persistent - I would have trashed this thing at 9 lbs.

It's the 12000 btu. You are right, it comes with 2.25 lbs of precharge, I have 33ft of lineset (33 x .22 = 7.26 lbs) 7.26 + 2.25 = 9.51 lbs to go in.

Yeah, that's my plan. I have it on the vacuum now, I can't wait to have it back. I'm in a hot and humid state and have been fighting the heat - this thing just iced the area without a sweat.

I assume it leaked out because it's not blowing cold but when I used the leak detector - it detected the presence of 410a. If there is any in there, it shouldn't be much. I already have an 11.5 lb can of 410a sitting here - bought it off the net.

Thanks for the reply! I hear that mini splits are critical charge system, so it has to be weighed in. I calculate it at 9.51 lbs - also, I don't have a high side measurement that I can take, that I know of.

That's true, I got them with the unit and with the extra lineset I ordered. It's 50ft - I'm running 33 There's enough for a 16ft lineset - which they ship with the unit. Here are the specs: Thank you for all your replies!

Hehehehh.... I'm awake! I really had no problems with the system, all the parts were there. I didn't even use the 16ft set that came with it, but it had all the parts. I know that my issue here is because I didn't tighten down the fitting enough. Is that what you are calling the quick...

This is a stealth grow in a state that is still in the dark ages so getting an HVAC guy out to go into my tent is out of the question. I know I'm taking a chance on the warranty but it is what it is..... This is a brand new pioneer 12000 BTU 13 seer (bought off Amazon for $671) I don't see...

I bought and installed a pioneer mini-split system. I got everything up and charged, the thing cooled the tent down in just a few minutes. It was awesome, until it stopped cooling as good. I found and fixed a leak on one of the fittings but now I need to recharge the system. I know I need...

I agree, I really think the MB2 decarb is off. I use 190 proof grain and at a 160f boiling point - it's not enough to decarb properly. The only place where we differ on opinion is the way I want my tincture. I want the whole plant - well all the plant that is covered with sticky trichomes...
