Gree GMV5 VRF Maintenance - Ⅲ. 21 Charging refrigerant and checking refrigerant quality
Ⅲ.Common Troubleshooting and Replacement of Electrical Components
21.Charging refrigerant and checking refrigerant quality
Before charging refrigerant, check its manufacturer and related information. Checking method of refrigerant quality: Measure and check the pressure of the entire refrigerant container against the saturation pressure temperature list. Verify the temperature parameter. If the difference between the actual temperature and the parameter valve is 3℃ or more, the refrigerant quality is unsatisfactory. // If the refrigerant is proved satisfactory, calculate the additional refrigerant charging amount according to the amount specified on the nameplate and pipe length. For a multi-modular system installation,if the refrigerant of only one outdoor is drawn out before maintenance, add 8-% refrigerant of the rated charging amount of that unit(specified on the nameplate of the unit).Start the system for a debugging test.

How about a basement window?
E2 что за ошибка?
Does anyone understand why the video shows a huge gap between the window sill and the AC unit, yet the last instruction says not to have a gap? Are there any side view diagrams showing a cut-away view of proper installation so I can see how much space should be under the AC unit? Thanks!
Hi~The video show a big gap that may not appear actually, it just want to let customer know obviously there may be a gap over there if you don' t put the insulation overthere. The size of the gap actually is only 1/2 inch.Thanks.

I needed this cover to protect my unit from cottonwood. I had mine just installed, it took just 30 seconds, and it fit perfectly! 😁😁😁
Thank you for your kind support, we have other air conditioning covers as well as accessories, you can also take a look.
Where can I get this window ac mesh cover? I have mosquitos in my room even I close all the windows and door, I suspected they could get in through the window air conditioner. I have the same Midea u shaped window air conditioenr.
This window air conditioner mesh cover is available on Aamzon.

01 AC A0 why coming....?
01 means Master AC means Cooling Mode A0 means All OK..
What is the Next step
Does it work? Would you post a video?
I don't have an outside window sill, so can't use this
If you have a inside window sill, you can still use it. But you will need a bigger size. :)
Great video. But can I do this w/ my older windows? The flat spacer is literally slanting downward & in between the window sill there's a gap & then a raised lip.
Yes, you can use our bracket with round spacer, we provide both flat spacer and round spacer inside the box. For more deteails, you can refer to this website page, there is an image for your easier understanding. www.amazon.com/LBG-Products-Universal-Conditioner-Designed/dp/B07PHDTFY3/ref=sr_1_21?dchild=1&keywords=window+ac+bracket&qid=1622184008&sr=8-21
I’m curious on how the ac doesn’t fall out tho?
The window AC is fixed by the window, but not safe enough sometimes. That's why many people come to us to buy the window AC bracket to make it firm and safer.
Great visual. Thanks
