FEATURES

All models are available with a wide variety of factory-mounted options such as stainless steel heat exchangers,phase monitor, dirty filter switch, and coil guard to make themsuitable 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 provideyears of dependable operation.

All models (including those with an economizer) are suitablefor either bottom or horizontal duct connections. Models withfactory installed power exhaust are suitable for bottomduct connections only. For bottom duct, you remove thesheet metal panels from the supply and return air openingsthrough the base of the unit. For horizontal duct, you replacethe supply and return air panels on the rear of the unit with aside duct flange accessory.

All models are available with these “factory mounted” outdoorair damper options:

• Single enthalpy economizer

• Single enthalpy economizer with power exhaust

• Motorized outdoor air damper

A fixed outdoor air intake assembly will be shipped in thereturn air compartment of all units ordered without an econo-mizer or motorized outdoor air damper option. The assemblyincludes a rain hood with a damper that can be set for 10, 15or 25% outdoor air. With bottom duct connections, the intakedamper assembly should be mounted over the opening in thereturn air panel. With horizontal ductwork, it should bemounted 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 highstatic drive option is available for applications with a higherCFM and/or static pressure requirement.

All compressors include scroll compressors and internal pres-sure relief. Every refrigerant circuit includes an expansionvalve, a liquid line filter-drier, a discharge line high pressureswitch and a suction line with a freezestat and low pressure/loss of charge switch to protect all system components.

• Simplicity™ Controls - Simplicity™ control boardshave standardized a number of features previously avail-able only as options or by utilizing additional controls.

• Low Ambient - An integrated low-ambient controlallows all units to operate in the cooling mode downto 0ºF outdoor ambient without additional assis-tance. Optionally, the control board can be pro-grammed to lockout the compressors when theoutdoor air temperature is low or when free coolingis available.

• Anti-Short Cycle Protection - To aid compressorlife, an anti-short cycle delay is incorporated into thestandard controls. Compressor reliability is furtherensured by programmable minimum run times. Fortesting, the anti short cycle delay can be temporarilyoverridden with the push of a button.

• Fan Delays - Fan on and fan off delays are fully pro-grammable. Furthermore, the heating and coolingfan delay times are independent of one another. Allunits are programmed with default values basedupon their configuration of cooling and heat.

• Safety Monitoring - The control board monitors thehigh and low-pressure switches, the freezestats, thegas valve, if applicable, and the temperature limitswitch on gas and electric heat units. The unit con-trol board will alarm on ignition failures, compressorlockouts and repeated limit switch trips.

• Nuisance Trip Protection and Strikes - To preventnuisance trouble calls, the control board uses a“three times, you’re out” philosophy. The high andlow-pressure switches and the freezestats must tripthree times within two hours before the unit controlboard will lock out the associated compressor.

• On Board Diagnostics - Each alarm will energize atrouble light on the thermostat, if so equipped, andflash an alarm code on the control board LED. Eachhigh and low-pressure switch alarm as well as eachfreezestat alarm has its own flash code. The controlboard saves the five most recent alarms in memory,and these alarms can be reviewed at any time.Alarms and programmed values are retainedthrough the loss of power.

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

All models are CSA approved.

• Warranty - All models include a one-year limited partswarranty on the complete unit. Compressors and electricheater elements carry a five-year warranty. Gas heatexchangers carry a 10-year parts warranty.

• Gas Heat Operation - All gas heat units are built withtwo heating sections for two equal stages of capacitycontrol. Each section includes a durable heat exchangerwith aluminized steel or optional stainless steel tubes, aredundant gas valve, spark ignition, power venting, anignition module for 100% shut-off and all of the safetycontrols required to meet the latest ANSI standards.

The gas supply piping can be routed into the heatingcompartment through a hole in the base pan of the unitor through a knockout in the piping panel on the front ofthe unit.

036-21477-001-A-0802


• Electric Heat Operation - All electric heat models (fac-tory installed only) are wired for a single power sourceand include a bank of nickel chromium elementsmounted at the discharge of the supply air blower to pro-vide a high velocity and uniform distribution of air acrossthe heating elements. Every element is fully protectedagainst excessive current and temperature by fuses andtwo thermal limit switches.

The power supply wiring can be routed into the controlbox through a threaded pipe connection in the base panof the unit or through a knockout in the wiring panel onthe front of the unit.

• BAS Controls - York’s Sunline™ series units offer fac-tory mounted BAS controls such as Novar, Honeywell,Johnson, and CPC.
