Note: Voltages listed are to show voltage range. How-
ever, units operating with over voltage and under
voltage for extended periods of time will experi-
ence premature component failure. Three phase
system unbalance should not exceed 2%.
General
1. Verifythecompatibilitybetweenthevoltageand
phaseoftheavailablepowerandthatshownonthe
unitdataplate.Lineandlowvoltagewiringmust
complywithlocalcodesortheNationalElectrical
Code,whicheverapplies.
2. Applycorrectlinevoltagetotheunit.A7⁄8"(22mm)
hole.Adisconnectswitchneartheunitisrequired
bycode.Powertotheunitmustbesizedcorrectly
andhavedualelement(ClassRK5)fusesoran
HACRcircuitbreakerforbranchcircuitovercurrent
protection.Seethedataplateforcorrectratings.
3. Connectthethermostat/subbasewiringwiththe
power“off”totheunit.
230 Volt Operation
All208-230voltsingle-phaseandthree-phaseunits
arefactorywiredfor208voltoperation.For230phase
operation,thelinevoltagetaponthe24-volttransformer
mustbechanged.Disconnectandcaptheredlead
wireandinterchangeitwiththeorangeleadwireonthe
primaryofthe24-volttransformer.
Fan Assembly
Allfanmotorsaremulti-speedPSCoroptionalECM
(sizes019-070)typewithintegralmountingbracketsand
thermaloverloadprotection.Themotorisisolatedfrom
thefanhousingforminimumvibrationtransmission.PSC
Fanmotorshaveaterminalstriponthemotorbodyfor
simplemotorspeedchangewithoutgoingbacktothe
controlbox.See"ChangingPSCFanMotorSpeed"on
page21.
Allthefan/motorassemblieshavearemovableorice
ringonthehousingtoaccommodatemotorandfan
wheelremovalwithoutdisconnectingtheductwork.
Thefanhousingprotrudesthroughthecabinetallowing
adequatematerialforconnectionofexibleduct.Each
modelunitisshippedfromthefactoryformaximum
performanceandminimumsoundrequirements.Fan
soundlevelsandperformancecanbeaffectedby
externalstaticpressure.
