Heat Pump units are single package,
reverse cycle air conditioners designed for outdoor installa-
tion on a rooftop or slab and for non-residential use. These
units can be equipped with factory or field installed electric
heaters for heating applications.
These units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electri-
cal wiring is factory installed and tested. The units require
electric power and duct connections. The electric heaters
have nickel-chrome elements and utilize single-point power
connection.
