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 installa-
tion and to provide years of dependable operation. All models
(including those with an economizer) are suitable for either bot-
tom 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.
All non-Scroll compressors include crankcase heaters and all
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
relay board with a compressor lockout circuit, a terminal strip
for thermostat wiring, plus an additional set of pin connectors
to simplify the interface of additional field controls. All units

spray test approval under ASTMB117 procedures. All models
are CSA listed. All models include a 1-year limited warranty
