This page shows the sources and review decisions behind the measurements used by ExactFit. Evidence for the exact model is identified separately from verified equivalent-model or same-chassis evidence. Missing values remain Unknown.
Last reviewed: 2026-09-05. 3 retained source records. 0 unresolved conflicts. Not every fit-critical input is supported.
Counts use distinct measurement records. Left and right ventilation share one per-side source record.
Some measurements on this page are not supported by an exact-model document. Each affected row identifies the model relationship and supporting evidence.
ExactFit does not have sufficient evidence for every fit-critical measurement. The fit checker will return Uncertain unless a known measurement already proves that the model does not fit.

Exact-model or explicitly covered Midea dimensional source.
The stored transfer does not identify both a supporting model and measurement-specific equivalence reasoning.
Retained research value: 29.5 in. It is preserved for audit but not accepted as a safe fit input.
Other evidence found
No materially different value is retained in the linked per-measurement audit records. This does not imply that every published source was searched.
Effect on fit result
This measurement supports the width comparison. An applicable cutout can replace additive clearances. If a required input is unknown and no applicable alternative requirement is established, the result is Uncertain unless another known requirement proves Does not fit.
