Description
The Cooper & Hunter Ceiling Cassette Pro 9,000 BTU 4-way ceiling cassette system pairs the CH-RES09-230VO outdoor heat pump with the CH-RSH09-12MCT indoor unit as an AHRI-matched single-zone ductless mini split (AHRI #215864194). It is rated at 21.6 SEER2 on R-454B refrigerant and runs on 208/230V single-phase power, heating and cooling one room or zone without ductwork.
The 4-Way Ceiling Cassette Pro recesses into a standard drop ceiling and spreads air in four directions. The Pro version has a dip switch to set 9K or 12K capacity on the 9-12K model, a refrigerant detection sensor (RDS) and a humidity sensor. The decorative panel is a separate part number and is included in this system.

Installation Notes
Mini split heat pumps must be installed by a licensed HVAC technician: the line set is flared, pressure tested, evacuated and charge-adjusted on site. R-454B is a mildly flammable (A2L) refrigerant, so A2L-rated tools and the manufacturer's procedures are required. Size the unit from a room load calculation rather than square footage alone. Each outdoor unit needs its own dedicated circuit sized to the rating plate (12 A MCA, 15 A max fuse).

Common Questions
Does this system come with a line set?
No. The line set, communication wire, wall sleeve, condensate line and mounting hardware are sold separately.
Can this outdoor unit run more than one indoor unit?
No. This is a single-zone (one outdoor to one indoor) system. Cooper & Hunter multi-zone condensers are listed separately.
