Fit Details
Verify Fit FirstVoltage matches; cooling capacity is 12,000 BTU/hr vs your 11,000 BTU/hr — the exact numbers are in the table above. Cabinet cutout dimensions differ — either a modification to the existing opening, or an adapter plate may be required. We'll confirm the right approach for your installation before your order ships.
Unit dimensions — what the tape measure will tell you
| N431226G050 | AT12RNWXX | Δ | |
|---|---|---|---|
| Height | 43.0″ | 43.99″ H | +1.0″ |
| Width | 11.5″ | 16.39″ W | +4.9″ |
| Depth | 14.0″ | 12.30″ D | -1.7″ |
The two manufacturer drawings are centered on each other for visual comparison only, because a shared mounting reference between the two units has not been verified. Verify every opening against your actual unit before any cutting or mounting. This comparison uses the standard AC AT12 footprint; the 48 VDC AT12RB has different dimensions. This comparison is a visual guide, not a cutting or drilling template. Openings can vary with voltage and production run — verify against your actual unit before any cutting or mounting, and follow the manufacturer's installation template.
