Hi, I know this is abit of a long shot but does anyone have any experience with Haier unit and hold any Spec on the condensing unit listed in the title?

I am mainly after the pre charge amount for the unit, i have tried with Haier but apparently they hold no info on these units anymore and the detail plates are weathered to the point that they are no longer visible. The only manual i can find online mentions nothing regarding the condensing unit and gas charge etc.

Any help is greatly appreciated!

Thanks
