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 power exhaust

•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.
