YORK Predator 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.

nents, installation and servicing of air conditioning equipment
can be hazardous. Only qualified, trained service personnel
should install, repair, or service this equipment. Untrained

ing coils and filters and replacing filters.

accompanying the equipment whenever working on air condi-
tioning equipment. Be sure to follow all other applicable

and have a fire extinguisher available during brazing opera-
tions.

ble damage during transit. If damage is evident, the extent of
the damage should be noted on the carrier's freight bill. A
separate request for inspection by the carrier's agent should
be made in writing.
