Duringtheice‐makingstage,thehotgassolenoidvalveisclosed.Thehotrefrigerantgasis


Duringtheiceharveststage,thesolenoidvalveisopen.Thehotrefrigerantgasispumpedoutoff
compressortoevaporatorthroughhotgasvalve.Asthehotgasisnotcooledbythecondenser,the
refrigerantmakestheevaporator(icemold)warm.Sosomeicetouchingtheevaporatoristhawed.

Whenthewatersupplypipeisconnectedwiththemainwatersupply,waterwillfillthewater
troughthroughthefloatervalvetillenoughwaterinsidewatertroughmakesfloatervalveclose.
Duringice‐makingstage,waterispumpedfromthewatertroughtothewaterdistributiontube.

CircuitDescription

1.ElectrifyStatusForTheFirstTime
Astheicemakerisproperlyinstalled.switchonthewatertap,letthewatertroughfull(reachon
thelevel),thenturntheICE/OFF/WASHswitchtotheICEpositiononthefrontpanel.Theicemaker
willstartworkingautomatically
Inthisstatus,thetimeisfixedabout3minutes.Thisfunctionisalsohelpfultoprotectthe
compressoravoidingrestartwithin3minutes.
Atthisstatus,theRed,Green,YellowLEDsarelighttogether.

2.Ice‐makingStatus
Thecompressor,motorfanandpumparepoweredon.Thehotgassolenoidvalveispoweredoff.
WhenthisgreenLEDislit,theunitisworkingintheicemakingmodecontrolledbyatemperature
probeontheevaporator.WhenthegreenLEDisflashing,theunitisworkingintheicemaking
modecontrolledbyafixedtimer.
Thefanmotorisalsocontrolledbyacondensersensor.Whentheambienttemperatureistoo
lower,themotorfanstopworkingforgoodcondensationtorefrigerant.

3.IceHarvestStatus
Thepumpispoweredoff.Thehotgassolenoidvalve,compressorandmotorfanispoweredon.
Thefanmotorisalsocontrolledbyacondensersensor.Whentheambienttemperatureistoo
lower,themotorfanstopworkingforgoodcondensationtorefrigerant.
TheYellowLEDindicatestheiceharveststatus.

4.IceFullStatusAndColdPreservationStage
Iftheicebinisfulfilledwithiceorthefullsensoriscovered,themachinestopsmakingiceand
turntocoldpreservationstageautomatically.
Inthisstatus,thecompressorworksregularlytokeepthelowertemperatureforlowericemelting.
Therestoftheelectriccomponentsarepoweredoff.TheREDLEDindicatestheicefullstatus
andtheGREENANDYELLOWLEDtogetherindicatesthecoldpreservationstatus.

InstructionsforLEDsandbuttons:
1.RedLED:Icefullindicatorlight.
WhenthisLEDislit,theicestoragebinisfulloficeorthereissomethingbetweentheice‐full
sensorintheicestoragebin.Theunitwillstopmakingice.Whenicecubesaretakenoutoftheice
storagebinmakingtheice‐fullprobefree,theredLEDwillkeepflashingfor3minutes.Thenthe
unitwillrestartandreturntotheicemakingmode.
2.GreenLED:Icemakingindicatorlight.
WhenthisLEDislit,theunitisworkingintheicemakingmodecontrolledbyatemperatureprobe
ontheevaporator.WhenthegreenLEDisflashing,theunitisworkingintheicemakingmode
controlledbyafixedtimer.
3.YellowLED:Iceharvestindicatorlight.
WhenthisLEDislit,theunitisworkingintheiceharvestmodecontrolledbyice‐fullprobe.

WhengreenLEDandyellowLEDislit,itmeanstheunitisworkinginthecoldpreservationstage.
4.Modebutton:
Mainlyforservice.Whenthisbuttonispressed,itcanchangefromicemakingmodetoiceharvest
mode,orfromiceharvestmodetoicemakingmode.Youcanjudgethemodefromthestatusof
thegreenandyellowLEDs.
IceSizeAdjustmentGuide:
FS‐55IM
1. Pressandholdthe“Clean”buttonandthe“Mode”buttontogetherforatleast3seconds.The
unitwillentertheIceSizeAdjustmentmode.The“HARVEST”LED(yellow)willbeblinking
continuouslyduringtheicesizeadjustment.
2. WhileintheIceSizeAdjustmentmode,pressthe“Clean”buttonorthe“Mode”buttonforthe
desiredicesize.
Smallericesetting:
Bypressingthe“Clean”button,youcandecreasethesizeoftheicecubes.The“ICE”LED(green)
willflashasyoulowertheicesizeandwillfinallybeblinkingatthesettingofsmallesticesize.
Largericesetting:
Bypressingthe“Mode”button,youcanincreasethesizeoftheicecubes.The“BINFULL”LED
(red)willflashasthelargersizeissetandwillblinkwhenthesettingoflargesticesizehasbeen
reached.
After10secondswithoutanyoperation,theunitwillreturntothepreviousmode.
NOTE:Duringtheicesizeadjustment,the“BINFULL”,“ICE”and“HARVEST”LEDSblinkingallat
onceindicatethattheunitisinthedefaultfactorysettingoftheicesize.
FS‐50IMOD
Icesizeadjust:Turnthescrewclockwise,andthesizeofindividualicecubeswillbelargerinthenextcycle;
thecycletimewillbelonger.Turnthescrewcounterclockwise,andtheicesizewillbesmallerinthenext
cycle.
NOTE:Itisnotagoodideatoadjusttheicesizeoftenorfornogoodreason,becausethecontrollermay
damaged.

MAJORFUNCTIONS
1. Theoperatingprocedureiscompletelyautomatic.
2. Whentheicestoragebinisfulloficecubes，themachinestopsmakingiceandproceedstothe
coldpreservationstageautomatically.Itstartsmakingiceagainaftericecubesareremoved.
3. ThedifferentcolorsoftheLEDdisplayindicatevariousworkmodes.
4. Thefanmotorrespondstotheambienttemperature.Ifitiscold,themotorwillstopworking
tokeepthecoolingsystemingoodworkingcondition.
5. Asensitiveprobeandaccuratetimerenhancetheperformanceoftheicemaker.
6. Acompressorprotectionsystemisbuiltin.
