Cooper&Hunter 4-Zone Ductless Mini Split AC & Heat Pump 36000 BTU (12K+12K+12K+12K), One-Way Ceiling Cassettes Units, 230V
Enjoy targeted, low-profile comfort with the Cooper & Hunter One-Way Ceiling Cassette system. A 36000 BTU outdoor condenser powers cassette heads designed to fit neatly between ceiling joists for a clean, built-in look and focused, directional airflow. This inverter heat pump provides independent control in 4 zones and delivers low-ambient heating performance down to -13 F.
One-Way cassettes use TU1 copper heat exchangers, an integrated condensate pump, and built-in Smart Kit app control. The R454B refrigerant supports efficient operation up to 24 SEER2. On supported 6K–12K models, the ENC1 dip-switch allows on-site capacity selection for added flexibility.
Key features
Designed for tight spaces
- Low-profile cassette design fits cleanly between structural ceiling beams
- Installation flexibility: requires only a ~3-inch wall penetration for conduits (typical install)
- Double-row tack holes help adapt mounting to different joist sizes
- Industry-exclusive 2-way installation (where supported) for easier placement and service access
Comfort & control
- 4-zone independent temperature control
- Precisely cool & heat only the areas you need
- Customized settings for different spaces with different comfort demands
- Turbo operation + multiple fan speeds
- Quiet operation (Outdoor as low as 64.5 dB(A); Indoor as low as 33 dB(A))
Built-in components
- Built-in water / condensate pump for reliable drainage
- Built-in circuit breaker (model dependent) for simpler, safer servicing
- TU1 copper heat exchangers for durability
- Sensors for comfort optimization (humidity/refrigerant detection where equipped)
Panel dimension note: One-Way cassette panel size may be consistent across indoor units (example: 53.25 × 18.5 × 1 in; panel included), but confirm exact dimensions in the indoor unit spec table for your model.
