GENERAL

YORKPredator® 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.

Only qualified, trained service personnel should install, repair, or service this equipment. Untrained personnel can perform basic maintenance functions of clean- ing coils and filters and replacing filters.
