Fit Details
Adapter FitSame cooling capacity and voltage as the N280426G700. Cabinet cutout dimensions differ, so an adapter plate is required to bridge the mounting pattern between the existing opening and the VoltAire AN04RQWXX — so you're not fabricating a new opening. Plan on some fitting work during the swap; we'll spec the exact adapter for your installation at order review.
Unit dimensions — what the tape measure will tell you
| N280426G700 | AN04RQWXX | Δ | |
|---|---|---|---|
| Height | 28.0″ | 30.00″ H | +2.0″ |
| Width | 11.5″ | 14.13″ W | +2.6″ |
| 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 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.
