Overview
The Cooper&Hunter CH-RH18MCT is an 18K Btu 4-way ceiling cassette indoor unit engineered for consistent, even comfort in 208–230V systems. It uses R454B refrigerant and is listed as a single-zone cassette (with flexibility for matched multi-zone applications when paired correctly). Air is distributed through an omni-directional 4-way discharge supported by a 360° air flow panel, helping reduce hot and cold spots. An activated carbon filter supports fresher indoor air, while GoldFin anti-corrosive coating and TU1 copper tubing promote long-term durability and efficient heat transfer. Comfort and reliability features include Anti Cold Air, Sleep and Turbo modes, a humidity sensor, self-diagnosis, and a built-in condensate pump with float switch (rated lift up to 20.9"). Control options include a built-in Smart Kit (C&H app), an included remote, and an included wall thermostat.
