DESCRIPTION
Sunline™ 2000 series convertible package rooftop mod­els 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 factory­mounted 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 pro­vide an exceptionally durable finish with the 750 hour salt spray process per ASTM-B117 test standard.
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, 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.

All supply air blowers are equipped with a belt drive that can be adjusted to meet the exact requirements of the job. A high speed drive accessory is available for applications with a higher CFM and/or static pressure requirement.
All compressors include internal pressure relief. Every refrigerant circuit includes an expansion valve, 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 two 75 VA transformers, two 24-volt circuit breakers and a relay board with two compressor lockout circuits, a terminal strip for thermostat wiring, plus an additional set of pin connectors to simplify the interface of addi­tional field controls.
All 208/230 and 460-volt models are ETL approved. All 208/230 and 575-volt models are CGA approved.
All models include a 1-year limited warranty on the complete unit. Compressors and electric heater ele­ments carry an additional 4-year warranty. Aluminized steel tubular heat exchangers carry an additional 9­year warranty.
All gas heat models are built with two heating sections for two equal stages of capacity control. Each section includes a durable heat exchanger with aluminized steel tubes, a redundant gas valve, spark ignition, power venting, an ignition module for 100% shut-off and all of the safety controls required to meet the latest ANSI standards.
The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through a knockout in the piping panel on the front of the unit.
All electric heat models are wired for a single power source and include a bank of nickel chromium ele­ments mounted at the discharge of the supply air blower to provide a high velocity and uniform distribu­tion of air across the heating elements. Every element is fully protected against excessive current and temper­ature by fuses and two thermal limit switches.
The power supply wiring can be routed into the control box through a threaded pipe connection in the base pan of the unit or through a knockout in the wiring panel on the front of the unit.
All internal factory wiring is color coded and numbered for ease in servicing and troubleshooting.
FACTORY-INSTALLED OPTIONS
ECONOMIZERS
Interlocked outdoor and return air dampers are posi­tioned by a fully modulating, spring return damper actu­ator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers. As the outdoor air intake dampers open, the return air dampers close. The changeover from compressor to economizer cool­ing is determined by one or two solid state enthalpy controls.
On single enthalpy, an outdoor air sensor determines when the outdoor air is cool and dry enough to provide “free” cooling. On differential enthalpy, one sensor monitors the outdoor air while a second sensor moni­tors the return air. Whenever the outdoor air is cooler and drier than the return air, the unit will switch to econ­omizer operation. For either option, the first compres­sor stage can provide additional cooling during economizer operation if the room thermostat calls for second stage.
The dampers and controls are installed and wired at the factory. Only the accessory rain hood needs to be assembled and installed in the field.
These economizer options can be used on all duct con­figurations.
POWER EXHAUST
Both the single and differential economizer options are available with power exhaust. Whenever the outdoor air intake dampers are opened for free cooling, the exhaust fan will be energized to prevent the condi­tioned space from being over-pressurized during econ­omizer operation.
The exhaust fan, motor and controls are installed and wired at the factory. Only the back-draft damper assembly needs to be field installed and the accessory rain hoods need to be assembled and installed in the field.
The power exhaust option can only be used on bottom duct configurations.
MOTORIZED OUTDOOR AIR INTAKE DAMPER
Interlocked outdoor and return air dampers are con­trolled by a 2-position, spring return damper actuator. The outdoor damper will open to some pre-set position whenever the supply air blower is operating and will drive fully closed when the blower shuts down.
The damper and controls are installed and wired at the factory. Only the accessory rain hood needs to be assembled in the field.
This damper option can be used on all duct configura-

SIDE DUCT FLANGES
One inch flanges replace the supply and return air pan­els on the rear of the unit to accommodate horizontal duct connections. These flanges can also be used indi­vidually for bottom supply/horizontal return or horizon­tal supply/bottom return. They cannot be used on units with power exhaust.
BAROMETRIC RELIEF DAMPER
This damper accessory can be used to relieve internal air pressure on units with an economizer but no power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct.
ECONOMIZER / POWER EXHAUST RAIN HOODS
A rain hood accessory must be used on units with an economizer, a motorized damper, or a combined econ­omizer with power exhaust option. These accessories include all the hood panels, the necessary components and hardware for field assembly.
