Heat Pump with Puron® (R-410A) Refrigerant

3 to 10 Nominal Tons

WeatherMaster® 50HCQ rooftop units were designed to be easy to install, maintain, and operate, with customer-requested features including a gage port, centralized control center, plug-and-play accessory board, ''no-strip screw'' collars, and handled access panels. Units are field-convertible to horizontal airflow without special adapter curbs or kits, making it easy for the installer to adjust to unexpected jobsite complications. Units are pre-wired and pre-charged with environmentally sound Puron (R-410A) refrigerant and are factory tested.
