| Install | The biggest U is a genuinely heavy install: roughly 75 lbs, so the sill bracket must be mounted dead level and you absolutely want two people to lift the chassis into it. Once seated, the window sash closes down through the U-channel — that's what isolates the compressor noise outside — and the window remains operable. Fit is 22-36 inch wide single/double-hung windows; check your opening height (13.75 in minimum) because the 12K chassis is tall. Get the rearward tilt right for drainage, especially on this platform. | Same bracket-first U-shape install as the 8K: sill bracket, drop the unit in, close the lower sash down through the U-channel so the glass blocks compressor noise. At 58 lbs it's dramatically lighter than Midea's 75 lb 12K — the easiest big U-shape to get into a window, though a helper is still smart. Fits 23.6-36 inch windows with 13.8 inches of vertical opening; use the long extension arm above 26 inches. Maintain the slight outward tilt for drainage. |
