York's Sunline 2000 TM units are convertible single package
heat pumps. Although the units are primarily designed for
curb mounting on a roof, they can also be slab-mounted at
ground level or set on steel beams above a finished roof.
Models are available with a wide variety of factory-mounted
options and field-installed accessories to make them suitable
for almost every application. All units are self-contained and
assembled on full perimeter base rails with holes in the four
corners for overhead rigging. Every unit is completely piped,
wired, charged and tested at the factory to simplify the field
installation and to provide years of dependable operation. All
models (including those with an economizer) are suitable for
either bottom or horizontal duct connections. Models with
power exhaust are suitable for bottom duct connections only.
For bottom duct, remove the sheet metal panels from the
supply and return air openings through the base of the unit.
For horizontal duct, remove the supply and return air panels
on the rear of the unit.

compressors have internal pressure relief. Every refrigerant
circuit includes a liquid line filter-drier, a discharge line high
pressure switch and a suction line with a freezestat and low
pressure/loss of charge switch.The unit control circuit
includes a 75 VA transformer, a 24-volt circuit breaker and a
