COOPER & HUNTER — Slim-Duct (R454B)
Cooper&Hunter Hyper 2-Zone Ducted Mini Split AC & Heat Pump 55000 BTU (24K+24K), Slim Duct Units, 230V
Bring flexible, concealed comfort to your space with the Cooper & Hunter Slim-Duct system. A 55000 BTU condenser powers slim-profile duct air handlers that disappear into ceilings, soffits, or chases for a clean, unobtrusive finish. This inverter heat pump provides independent control in 2 zone(s) and supports low-ambient heating performance down to -22 F.
Slim-Duct air handlers use TU1 copper tubing, medium / high static pressure blower performance, built-in Smart Kit connectivity, and R454B refrigerant (low-GWP) for efficient operation up to 22.2 SEER2. Equipped models include a refrigerant sensor to help maintain optimal operation.

6K–12K capacity selection (ENC1)
On supported 6K–12K Multiple Capacity Slim-Duct models, the ENC1 dip switch is used for capacity changes. When paired with single-zone condensers, the indoor unit can automatically adjust to match condenser capacity. When paired with multi-zone condensers, set ENC1 to select the desired indoor capacity.
- ENC1 from “0” to “1” → 6,000 BTU/H
- ENC1 from “0” to “2” → 9,000 BTU/H
- ENC1 from “0” to “3” → 12,000 BTU/H
If this product does not include a 6K–12K indoor unit, ignore this section. Your spec table and will reflect what applies.
