2.1A In Humid Area, No Ducting
ThesimplestinstallationistoplacetheHI-EDry100inthehumidareawithnoducting.Theairinletontop
&outletonthesidemustbeatleast1’fromwallsandotherobstructionstoairow.
2.1B In Humid Area, Duct inlet and/or Outlet
Ifthehumidareaisverylargeorhashighceilings,dehumidicationcanbeimprovedbyaddinganinlet
and/oroutletducttocirculateanddestratifystagnantareas.Foralargearea,addinletoroutletductingto
createowacrossthearea’sgreatestlength.
Forareaswithceilingshigherthan12’,useaninletducttodrawwarm,moistairfromneartheceiling.See
section2.4forattachingductcollars&ducting.
2.1C In Remote Area, Duct Inlet & Outlet
Itisoftendesirable,especiallyinnishedareas,toinstalltheHI-EDry100inanadjacentequipmentroom
orunnishedarea.Airistransferredbetweenthehumidroomandtheunitviaducting.
ThefactorymountedhumiditycontrolontheHI-EDry100cabinetmaynotsensethehumidityinthehumid
roomaccuratelyenoughwiththisinstallationmethod.Ifso,anadditionalhumiditycontrolcanbemounted
inthehumidroomandwiredtotheHI-EDry100.Localelectricalcodesmustbefollowedwhenwiringthe
control.
2.1D In Remote Area, Duct Outlet Only
AsimplerremoteinstallationmethodthantheoneaboveusesductingonlybetweentheHI-EDry100
dischargeandthehumidroom;theHI-EDry100inletdrawsairfromtheroominwhichit’slocated.This
workswellifthereisanadequateairowpathbetweenthetworooms;e.g.,highdoorundercut,louvered
doororwallgrill.Thiseliminatestheneedtoremotemountthehumiditycontrol.Thereareseveralpotential
disadvantagestousingthismethod.First,humidairisdrawnintotheroomwheretheHI-EDry100is
located.Second,toaccuratelysensehumidity,theblowerintheHI-EDry100mayneedtoruncontinuously
todrawairfromthehumidroomintotheHI-EDry100room.Third,aslightnegativepressureiscreated
intheroomwiththeHI-EDry100whichcouldbackdraftopencombustiondeviceslocatedthere.Ifsuch
devicesarepresent,callthefactoryforspecicinstructionsbeforeusingthisinstallationmethodorconsider
theoptionbelow.
2.1E In Remote Area, Duct Inlet Only
WhentheHI-EDry100islocatedinaroomseparatefromthemainareatobedehumidied,itmaybe
desirabletodehumidifyand/orslightlypressurizethatroom.Pressurizationassuresthatopencombustion
devicesdonotbackdraftaswouldbethecaseiftheroomwassufcientlyde-pressurized.Thiscanbe
accomplishedbyinstallingaductfromthehumidroomtotheHI-EDry100inletandbyallowingtheHI-E
Dry100todischargethedehumidiedairintotheroominwhichit’slocated.Anadequateairowpath
mustexistbetweenthetworoomsforthismethodtoworkwell.Anadditionalhumiditycontrolmayneedto
bemountedinthehumidareaandwiredtotheHI-EDry100toaccuratelymaintainthedesiredhumidity.
Localelectricalcodesmustbefollowedwhenwiringthecontrol.
2.2 Electrical Requirements
TheHI-EDryplugsintoacommongroundedoutletona15Ampcircuit.Itdrawsbetween6and7Amps
undernormaloperatingconditions.Ifusedinawetarea(pool,sparoom,orbasementpronetoooding),a
groundfaultinterrupterprotectedcircuitisrequired.
Ifanextensioncordisrequired,itmusthaveaminimumof16gaugeconductorsiflessthan25feetlongand
14gaugeifgreaterthan25feet.

2.3 Condensate Removal
TheHI-EDry100isequippedwithacondensatepumptoremovethewaterthatiscondensedduring
dehumidication.Thisallowsthecondensatetobedisposedofatadistantlocation,ortobepumpedtoa
levelabovetheHI-EDry100.ThecondensatepumpismountedinsidetheHI-EDry100asanintegralpart
oftheunit.Ifthecondensatemustbepumpedmorethan18feetabovetheunit,asecondpumpmustbe
addedtorelaythecondensate.
2.4 Ducting
2.4A Optional Ducting
Aninletshroudwitha8”roundcollarandan8”roundexhaustcollarareavailablefromthefactorythatwill
allowroundductingtobeattachedtotheinletand/oroutletoftheHI-EDry100.
2.4B Ducting for Dehumidication
DuctingtheHI-EDry100asmentionedinsections2.1B-2.1Erequiresconsiderationofthefollowingpoints.
DuctSizing:Fortotalductlengthsupto25’,useaminimum8”diameterroundorequivalentrectangular.
Forlongerlengths,useaminimum10”diameterorequivalent.Grillsordiffusersontheductendsmustnot
excessivelyrestrictairow.
IsolatedAreas:Effectivedehumidicationmayrequirethatductingbebranchedtoisolated,stagnantareas.
Use6”diameterbranchductingtoeachoftwoorthreeareas;use4”toeachoffourormoreareas.
2.4C Ducting for Fresh Air
FreshaircanbebroughtintothestructurecontinuouslybyconnectingaductfromoutsidetotheHI-EDry
100inletandbyturningonthefanswitch.Advantagesofthisformofventilationinclude:
1. Outsideairislteredbeforeenteringthebuilding.
2. OutsideairwillbedehumidiedbeforeenteringiftheHI-EDry100isrunning.
3. Drawingairfromoutsideandblowinginsideaidsinpressurizingthestructure.Thishelpsprevent
unlteredandundehumidiedairfromenteringelsewhere.Italsoreducesthepotentialforcarcinogenic
radongastoenter.
4.Theneedforanalternateventilationdevicemaybeeliminated.
3. Operation
3.1 Humidity Control Adjustment
Thehumiditycontroldevicewillruncontinuouslyuntiltherelativehumidity(RH)isreducedtothe
humiditycontroldialsetting.SettingthehumiditycontroltolowerRHlevelswillNOTincreasetheunit’s
dehumidicationrate,itwillsimplyrunlongertoreducethearea’sRHtothesetting.TheHI-EDry100unit
(andrefrigerantbasedhumiditycontroldevicesingeneral)willreduceawarmspace’sRHtoalowerlevel
thanthatofacoolspace.Itisthereforepointlesstosetthehumiditycontroltoexcessivelylowlevelsincool
rooms.Doingsowillresultinlongperiodsofineffectivehumiditycontroldeviceruntime.
Aqualityhumiditymeterisrecommendedtoaccuratelymonitorhumiditylevels.Foraquoteonaquality
humiditymeter,callthefactory.

3.2 Fan Switch
TurningthefanswitchONwillcausetheunit’sinternalblowertoruncontinuously,whethertheunitis
dehumidifyingornot.Thisfunctionisdesirableiftheunitisusedforaircirculationorfreshairventilation.
3.3 Defrost Control Adjustment
WhentheHI-EDry100isusedinacoolarea,frostwillformonthecoolingcoilasitdehumidies.When
enoughfrostforms,thedefrostthermostatwillinitiatethetimeddefrostcycle.Thecycleperiodicallyturns
offthecompressorwhileallowingtheblowertorun.Theairthattheblowerdrawsthroughthecoolingcoil
meltsthefrost.
Thedefrostcycleisautomaticanddesignedforoptimumperformanceabove50°F.
4.Maintenance
4.1 Air Filter
TheHI-EDry100isequippedwitha2”thick,35%efcientpleatedfabricairlterthatmustbechecked
regularly.Operatingtheunitwithdirtylterswillreducethehumiditycontroldevice’scapacityand
efciencyandmaycausethecompressortocycleoffandonunnecessarilyonthedefrostcontrol.
Theltercangenerallybevacuumedcleanseveraltimesbeforeneedingreplacement.Replacementlters
canbeorderedfromthefactoryorpurchasedlocallyifavailable.DONOToperatetheunitwithoutthelter
orwithalesseffectivelterastheheatexchangecoilsinsidetheunitcouldbecomecloggedandrequire
disassemblytoclean.
5. Service
CAUTION: Servicing the HI-E Dry 100 with its high-pressure refrigerant system and high voltage circuitry
presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only
qualied service people should service this unit.
5.1 Warranty
Awarrantycerticatehasbeenenclosedwiththisunit.Readitbeforeanyrepairisinitiated.Ifawarranty
repairisrequired,callthefactoryrstat1-800-533-7533forwarrantyclaimauthorizationandtechnical
assistance.
5.2 Technical Description
RefertoFigure3.TheHI-EDry100usesarefrigerationsystemsimilartoanairconditioner’storemoveheat
andmoisturefromincomingair,andaddheattotheairthatisdischarged.
Hot,high-pressurerefrigerantgasisroutedfromthecompressortothecondensercoil.Therefrigerant
iscooledandcondensedbygivingupitsheattotheairthatisabouttobedischargedfromtheunit.
Therefrigerantliquidthenpassesthroughtwocapillarytubes,whichcausetherefrigerantpressureand
temperaturetodrop.Itnextenterstheevaporatorcoilwhereitabsorbsheatfromtheincomingairand
evaporates.
Theevaporatoroperatesinaoodedcondition,whichmeansthatitshouldalwaysbefullofliquid
refrigerantduringnormaloperation.Aoodedevaporatorshouldmaintainconstantpressureand
temperatureacrosstheentirecoil,frominlettooutlet.

5.6 Compressor/Capacitor Replacement
Thiscompressorisequippedwithatwoterminalexternaloverload,runcapacitor,butnostartcapacitoror
relay(seeFig.4).
CAUTION-ELECTRICAL SHOCK HAZARD: Electrical power must be present to perform some tests; these
tests should be performed by a qualied service person.
5.6A Checking Compressor Motor Circuits
PerformthefollowingtestsiftheblowerrunsbutthecompressordoesnotwiththehumiditycontrolON.
1. TurnthehumiditycontrolOFFandunplugtheunit,removethecabinetfront(6screws).
2. PlugintheunitandturnthehumiditycontrolON.Useavoltmetertocheckfor110to120voltsbetween
(a)therelayterminalthattheblackwirefromthecompressorconnectstoand(b)thecapacitorterminal
withthe(2)whitewires,(1)redwire&(1)brownwireconnected.Ifvoltageispresent,gotostep3.If
novoltage,thedefrostthermostat,therelayorthecondensatepumpsafetyswitchareopenorthereis
alooseconnectioninthecompressorcircuit.Testeachcomponentforcontinuity;seetheappropriate
sectionifadefectissuspected.
3. TurnthehumiditycontrolOFFandunplugtheunit,thendisconnecttheredandyellowwiresfrom
compressorterminalsR&S.Usinganohmmetercheckcontinuitybetweenthepointslistedbelow.
4. CompressorterminalsCandS:Nocontinuityindicatesanopenstartwinding;thecompressormustbe
replaced.
5. CompressorterminalsCandR:Nocontinuityindicatesanopenrunwinding;thecompressormustbe
replaced.
6. CompressorterminalCandoverloadterminal1:Nocontinuityindicatesadefectiveoverloadlead.
7. Overloadterminals1and3:Ifthereisnocontinuity,theoverloadmaybetripped;wait10minutesand
tryagain.Ifthereisstillnocontinuity,itisdefectiveandmustbereplaced.
8. CompressorterminalCandcompressorcase:Continuityindicatesagroundedmotor;thecompressor
mustbereplaced.
9. Disconnectthewiresfromthecapacitor.SettheohmmetertotheRx1scale;thecapacitorisshortedand
mustbereplacedifcontinuityexistsacrossitsterminals.Ifthereisnoneedlemovementwiththemeter
setontheRx100000scale,thecapacitorisopenandmustbereplaced.
10.Reconnectthewirestothecompressorandcapacitor;pluginandturnontheunit.Ifthecompressor
failstostart,replacetheruncapacitor.
11.Iftheunitstilldoesnotstart,addingahard-startkitwillprovidegreaterstartingtorque.Ifthisdoesnot
work,thecompressorhasaninternalmechanicaldefectandmustbereplaced.
5.6B Replacing a Burned Out Compressor
Therefrigerantandoilmixtureinacompressorischemicallyverystableundernormaloperatingconditions.
However,whenanelectricalshortoccursinthecompressormotor,theresultinghightemperaturearccauses
aportionoftherefrigerantoilmixturetobreakdownintocarbonaceoussludge,averycorrosiveacid,and
water.Thesecontaminantsmustbecarefullyremovedotherwiseevensmallresidueswillattackreplacement
compressormotorsandcausefailures.
