DESCRIPTION

Sunline™ 2000 series convertible package rooftop mod-
els have two independent refrigerant circuits for efficient
part load operation. 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.
Cooling only, cooling with gas heat and cooling with electric
heat 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 field installation and to provide
years of dependable operation. Powder paint cabinets pro-
vide an exceptionally durable finish with the 750 hour salt
spray process per ASTM-B117 test standard.
All models (including those with an economizer) are suit-
able for either bottom or horizontal duct connections. Mod-
els with power exhaust are suitable for bottom duct
connections only. For bottom duct, you remove the sheet
metal panels from the supply and return air openings
through the base of the unit. For horizontal duct, you
replace the supply and return air panels on the rear of the
unit with a side duct flange accessory.
All models are available with five different outdoor air
damper options:
• Single enthalpy economizer
• Differential (dual) enthalpy economizer
• Single enthalpy economizer with power exhaust
• Differential (dual) enthalpy economizer with
• Motorized outdoor air damper
A fixed outdoor air intake assembly is shipped in the return
air compartment of all units ordered without an economizer
or motorized outdoor air damper option. The assembly
includes a rain hood with a damper that can be set for 10,
15 or 25% outdoor air. With bottom duct connections, the
intake damper assembly should be mounted over the
opening in the return air panel. With horizontal ductwork, it
should be mounted on the return air duct.
