DESCRIPTIONSunline 2000 units are highly efficient, convertible rooftops. Allmodels have dual refrigerant circuits for efficient part loadoperation. Although the units are primarily designed for curbmounting on a roof, they can also be slab-mounted at groundlevel or set on steel beams above a finished roof.These units are designed and manufactured under ISO 9002Quality System Certification.Cooling only, cooling with gas heat and cooling withsupplemental electric heat units are available with a widevariety of field-installed accessories to make them suitable foralmost every application.All units are self-contained and assembled on full perimeterbase rails. The base rails have holes in the four corners foroverhead rigging.Every unit is completely piped, wired, charged and tested atthe factory to simplify the field installation and to provide yearsof dependable operation. Powder paint cabinets provide anexceptionally durable finish with the 750 hour salt sprayprocess per ASTM-B117 test standard.All models are available with three different outdoor air damperaccessosries:• Single enthalpy economizer• Differential enthalpy economizer• Motorized outdoor air intake damperAll models (including those with an economizer ) are suitablefor either downflow or sideflow duct connections. For downflowduct, remove the sheet metal panels from the supply and returnair openings through the base of the unit. For sideflow duct,replace the supply and return air panels on the rear of the unitwith a side duct flange accessory.A fixed outdoor air intake assembly is shipped in the return aircompartment of all units. The assembly includes a rain hoodwith a damper that can be set for 10, 15 or 25% outdoor air.With bottom duct connections, the intake damper assemblyshould be mounted over the opening in the return air panel.With horizontal ductwork, it should be mounted on the returnair duct.All supply air blowers are equipped with a belt drive that canbe adjusted to meet the exact requirements of the job.All compressors include crankcase heat and internal pressurerelief. Every refrigerant circuit includes an expansion valve, aliquid line filter-drier, a discharge line high pressure switch anda suction line with a freezestat and low pressure switch. Theunit control circuit includes a 75 VA transformer, a 24-volt circuitbreaker and a relay board with two compressor lockout circuits,a terminal strip for thermostat wiring, plus an additional set ofpin connectors to simplify the interface of additional fieldcontrols.All gas heat models are built with two heating sections for twoequal stages of capacity control. Each section includes adurable heat exchanger with aluminized steel tubes, aredundant gas valve, spark ignition, power venting, an ignitionmodule for 100% shut-off and all of the safety controls requiredto meet the latest ANSI standards.The gas supply piping can be routed into the heatingcompartment through a hole in the base pan of the unit orthrough a knockout in the piping panel on the front of the unit.All electric heat models are wired for a single power source andinclude a bank of nickel chromium elements mounted at thedischarge of the supply air blower to provide a high velocity anduniform distribution of air across the heating elements. Everyelement is fully protected against excessive current andtemperature by fuses and two thermal limit switches.The power supply wiring can be routed into the control boxthrough a threaded pipe connection in the base pan of the unitor through a knockout in the wiring panel on the front of the unit.530.26-TG3YI (1294)SINGLE PACKAGEGAS / ELECTRIC UNITS ANDSINGLE PACKAGE AIR CONDITIONERSD3CE / D3CG 180 & 240(WORLD 50 HZ)SUNLINE 2000®DCGShown
