Where it may fit
- Comparing dedicated gravity-drained units for a sealed crawl space or basement.
Before you buy
- Confirm the exact current SKU, refrigerant generation and matching installation manual.
- Verify access clearance and the complete condensate-discharge route before ordering.
The tradeoffs
- The product navigation swaps horizontal dimension labels; this record uses the L × W × H order explicitly labeled in the current R32 specification. Add collar, hose and service space before deciding fit.
