Hello Xringer,
Please check how much "Dirty Electricity" is produced by your babies. It's well known that inverters are the main source of that for residential circuits. It's very hazardous for health. Just Google "Dirty electricity" You need to add a low pass filter next to switch boxes to maintain good sinusoidal 60Hz. Looks like you quite qualified to measure and mitigate that high frequency noise. Quote:

Here's a link to their current statement. I found this to be very interesting, especially when I recalled that the very heart and soul of the ARRL is based on electro magnetic radiation. What do you suppose infected their overheated brains Vern? Maybe you should contact the ARRL and set them straight... I'm sure they'd like to hear from you. -AC |
The amount of EMI one of those inverters puts out is pretty small, especially if it's designed to meet class B requirements. Combine that with distance and you realistically don't have to worry about it. Chances are, you're getting far more EMI from the keyboard you were typing on.
If you're worried about it or are actually having (radio reception) problems with the EMI, some ferrite cores will work well to attenuate it. |
I need to put some of those ferrite cores on my solar charge controller.
It's a PWM charger that really buzzes up the lower RF bands.. |

No problems so far. I change the oil before each use. When I first got it, I did some testing.
It might be posted on this thread.. Can't remember. |

Xringer's advice about fresh oil every use is an important point to keep in mind. Every time you use the unit, the oil absorbs moisture and any other gaseous contaminate. So, you want fresh oil with each use, AND if you're going to be storing your vac pump, you should put fresh, uncontaminated oil in it to prevent possible pump corrosion. Cheap insurance. -AC |

http://www.autozone.com/autozone/acc...er=952206_0_0_ This post is very useful for me. I have read a lot on installing my mini split and this is the first place I have seen this part spelled out. I was wondering what the best way was to not put air into the nicely hard vac AC. Thanks! for the info. |
Just joined and wanted to say hello and more importantly thank Xringer and AC Hacker for the detailed information within these threads. Honestly, I can't thank you (and everyone else for their contribution) enough.
Last weekend I installed a Mitsubishi split with the MHK1 (re-branded Honeywell Focus Pro) and RedLINK gateway. I plan to eventually post all the information/pics but will hold off until I actually start up the equipment. I ran into something completely unexpected. It seems that the Mitsubishi systems (may exclude city series) don't utilize a 5/16" service port (expected when working with 410), rather they have chosen to maintain a 1/4". This rendered my ball valve/core removal tool useless and since no one locally would sell me the proper size, I had to defer to the internet (should receive today). So for those considering the Mr. Slims, this was the only thing stopping me last weekend from completing the install. |
