Overview
Cooper&Hunter Slim Duct indoor units provide an inconspicuous ducted solution by hiding the air handler in attics or ceiling crawl spaces, delivering comfort to one or more areas without the energy losses commonly associated with traditional central ducted systems. Duct runs can be directed into separate areas that are collectively controlled by a single wall thermostat (controller/system dependent).
The CH-M09DTUI is a 9,000 BTU slim-duct indoor unit designed for single-zone or compatible multi-zone applications in 208–230V systems. It supports multiple control methods, including the included remote and compatibility with wired controllers (120X/120N).

Important
Install with a licensed HVAC professional. This is a concealed ducted indoor unit intended to be matched with a compatible outdoor system. Confirm electrical requirements (208–230V), refrigerant piping sizes (1/4" liquid, 3/8" gas), and duct layout/static pressure needs (ESP 0–0.32). Condensate drainage uses a 1" drain connection. Wired controller and wall thermostat setups depend on the controller model and system pairing.
