DESCRIPTION

50FCQ units are standard-efficiency, single-packaged heat pump units with Ecoblue™ Technology that are pre-wired and pre-charged with Puron® refrigerant. Electric heat is available as a field-installed accessory. The units are fully factory-tested and agency-certified. These units have field convertible supply and return openings and are intended for installation on a roof curb accessory (ordered separately), or for slab mounting (for horizontal duct connections). Units may be ordered with various factory-installed options. Field-installed accessories are also available.
