DESCRIPTIONYork’s Sunline 2000 units are convertible single package units.All models have dual independent refrigerant circuits forefficient part load operation and maximum comfort control.Although the units are primarily designed for curb mounting ona roof, they can also be slab-mounted at ground level or set onsteel beams above a finished roof.

Cooling only, cooling with gas heat and cooling with electricheat models are avai lable with a wide var iety offactory-mounted options and field-installed accessories tomake them suitable for almost every application.

All units are self-contained and assembled on full perimeterbase rails with holes in the four corners for overhead rigging.

Every unit is completely piped, wired, charged and tested atthe factory to simplify the field installation and to provide yearsof dependable operation.

All models (including those with an economizer) are suitablefor either bottom or horizontal duct connections. Models withpower exhaust are suitable for bottom duct connections only.For bottom duct, you remove the sheet metal panels from thesupply and return air openings through the base of the unit. Forhorizontal duct, you replace the supply and return air panelson the rear of the unit with a side duct flange accessory.

All models are available with five different outdoor air damperoptions:

• 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 will be shipped in the returnair compartment of all units ordered without an economizer ormotorized outdoor air damper option. The assembly includes arain hood with a damper that can be set for 10, 15 or 25%outdoor air to be entered into the unit. With bottom ductconnections, the intake damper assembly should be mountedover the opening in the return air panel. With horizontalductwork, it should be mounted on the return air duct.

All supply air blowers are equipped with a belt drive that canbe adjusted to meet the exact requirements of the job. A highspeed drive accessory is available for applications with a higherCFM and/or static pressure requirement.

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/loss of chargeswitch. The unit control circuit includes a 75 VA transformer, a24-volt circuit breaker and a relay board with two compressorlockout circuits, a terminal strip for thermostat wiring, plus anadditional set of pin connectors to simplify the interface ofadditional field controls.

All units have long lasting powder paint cabinets with 750 hoursalt spray test approval under ASTM-B117 procedures.

All 208/230 and 460-volt models are ETL approved. All 208/230and 575-volt models are CGA approved.

All models include a 1-year limited warranty on the completeunit. Compressors and electric heater elements carry anadditional 4-year warranty. Aluminized steel tubular heatexchangers carry an additional 9-year warranty.

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.

All internal factory wiring is color coded and numbered for easein servicing and troubleshooting.

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.

FACTORY-INSTALLED OPTIONSECONOMIZERS - Interlocked outdoor and return air dampersare positioned by a fully modulating, spring return damperactuator capable of introducing up to 100% outdoor air withnominal 1% leakage type dampers. As the outdoor air intakedampers open, the return air dampers close. The changeoverfrom compressor to economizer cooling is determined by oneor two solid state enthalpy controls.On single enthalpy, an outdoor air sensor determines when theoutdoor air is cool and dry enough to provide “free” cooling. Ondifferential enthalpy, one sensor monitors the outdoor air whilea second sensor monitors the return air. Whenever the outdoorair is cooler and drier than the return air, the unit will switch toeconomizer operation. For either option, the #1 compressorcan provide additional cooling during economizer operation ifthe room thermostat calls for second stage.The dampers and controls are installed and wired at the factory.Only the rain hood needs to be assembled and installed in thefield.These economizer options can be used on all ductconfigurations.POWER EXHAUST - Both the single and differentialeconomizer options are available with power exhaust.Whenever the outdoor air intake dampers are opened for freecooling, the exhaust fan will be energized to prevent theconditioned space from being over-pressurized duringeconomizer operation.The exhaust fan, motor and controls are installed and wired atthe factory. The rain hood and the back-draft damper need tobe assembled and installed in the field.The power exhaust option can only be used on bottom ductconfigurations.MOTORIZED OUTDOOR AIR INTAKE DAMPER - Interlockedoutdoor and return air dampers are controlled by a 2-position,spring return damper actuator. The outdoor damper will opento some pre-set position whenever the supply air blower isoperating and will drive fully closed when the blower shutsdown.The damper and controls are installed and wired at the factory.Only the rain hood needs to be assembled in the field.This damper option can be used on all duct configurations.

FIELD-INSTALLED ACCESSORIESROOF CURBS - 14" high roof curbs provide a water-tight sealbetween the unit and the finished roof. These full perimetercurbs meet the requirements of the National RoofingContractors Associat ion (NRCA) and are shippedknocked-down for field assembly. They’re designed to fit insidethe base rails of the unit and include both a wood nailing stripand duct hanger supports.ANTI-RECYCLE TIMERS - Two solid state timers prevent thecompressors from short-cycling. Once a compressor isde-energized, it will remain de-energized for approximately fiveminutes.HIGH ALTITUDE NATURAL GAS - Burner orifices and pilotorifices are provided for proper furnace operation at altitudesup to 6,000 feet.PROPANE - Burner orifices, pilot orifices and gas valve partsare provided to convert a natural gas furnace to propane.

HIGH ALTITUDE PROPANE - Burner orifices and pilot orificesare provided for proper furnace operation at altitudes up to6,000 feet. This accessory supplements the basic propaneconversion kit.SIDE DUCT FLANGES - One-inch flanges replace the supplyand return air panels on the rear of the unit to accommodatehorizontal duct connections. These flanges can also be usedindividually for bottom supply/horizontal return or horizontalsupply/bottom return. They cannot be used on units with powerexhaust.BAROMETRIC RELIEF DAMPER - This damper accessorycan be used to relieve internal air pressure on units with aneconomizer but no power exhaust. This accessory includes arain hood, a bird screen and a fully assembled damper. Withbottom duct connections, the damper should be mounted overthe opening in the return air panel. With horizontal ductwork,the accessory should be mounted on the return air duct.HIGH SPEED DRIVE - A smaller blower pulley and a shorterbelt increase the speed of the supply air blower for applicationswith a higher CFM and/or static pressure requirement.LOW AMBIENT CONTROLS TO 0°F - An autotransformer anda thermostat maintain stable system operation by reducing thespeed of the #1 condenser fan motor at low outdoortemperatures. The kit also includes a 1-phase motor to replacethe unit’s standard 3-phase condenser fan motor. Standardunits can operate down to 25°F.

SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS- Includes a slide-in / plug-in damper assembly with fullymodulating spring-return monitor actuator capable ofintroducing up to 100% outdoor air with nominal 1% leakagetype dampers.

The enthalpy system contains one sensor that monitors theoutdoor air and determines when the air is cool enough anddry enough to provide "free" cooling.The rainhood is painted to match the basic unit and must befield-assembled before installing.Power exhaust is not available as a field installed option.DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZERS -Includes a slide-in / plug-in damper assembly with fullymodulating spring-return monitor actuator capable ofintroducing up to 100% outdoor air with nominal 1% leakagetype dampers.This enthalpy system contain one sensor that monitors theoutdoor air and one sensor that monitors the return air.
