△Coolingsystemfaults.
○Howtodiagnosefaults:
Itshouldtakeapproximate3hourstoreachthelowestsettingtemperatureof5℃foranemptyunit(assuming ambient
tempof32degreescentigradeandcontinuousoperation). Ifnot,checkthecompressor,coolingfans,controller, andsensors.
Ifall theseareworking normally,thereisprobablyacoolingsystem’sfault.
○Howtorepairthedefualt
1. Checkthe compressor
Turnonthe unitandcheckthere iselectricitycurrentflowingtothecompressorusinga calipertypeAmpmeter,the
currentshouldbewithin0.6to2Amps.Ifthereadingsarenotinthisrange, turnoffandcutoffthepipes (See Fig.8
showingG) andthesealpliers (See Fig.8showing E.) fromthecompressor,thenturntheunit onagain(inthiscase
onlyrun thecompressorforafewminuets,soastoavoidthecompressorabsorbmoistair)andrecheckthe
currentand ifthereispressureattheoutletpipe. Ifthecurrentreadingisstill outofrangespecifiedaboveandno
pressurefromthe compressoroutlet, replace the whole compressor.
2. Checkthecoolingsystempipe work:
Carefullycheckthecooling systemafterverifying thecompressorisworking normally.Thenfollowtheprocedure
below.
1>. Thencutoffprocess pipeandchecktherefrigerant.Ifthereisnotenoughrefrigerant,thedefualt oftherefrigerant
systemshouldbecausedbytheleaking.Ifthe refrigerantissufficient., itisprobablyjamedinthecapillary.
2>.Ifthedefault is concentratedon thecooling system,thechecking procedureis as below.
A.Cutoff theventpipeofthecompressor, andinfuse0.8-1MPnitrogenby process pipe, andpleaseputthehandclose
tothecutkerfoftheventpipe.Ifthereis alittlegas leakformtheterminal,it meansnormal, orit is jamed.
B. Makesurethecapilaryisworkingnormally,whenthedrainpipeisconnetcedagain,and infuse0.8-1MPnitrogen
thentesttheleakageifthecoolingsystemofthesoldering pointwiththesoapwater.Checkfromthethesoldering
pointarroundthecompressor(Fig.8&Fig.9、Fig.9.1),andifeverythingis ok,removetheair-ductboardand chech
thesoldering pointaround evaporator(Fig.6 &Fig.7).pleaseseetheremovemethodand theprocedureasbelow.
(Fig.1,Fig.2,Fig.3,Fig.4&Fig.5)
C.IfallthesolderingpointinB isnotleaking,therearetwopossibility, oneis leakageintheinnercondenser,another
isthedamageon theparts（suchas evaporator,condenserand soon）inthecoolingsystem.Ifitis theinnerdamage,
itcannotberepaired,andifthedamageontheparts, replace them.
3>.Makesurethatthereis notleakageinthecooling system, refilltherefrigerant.
3.Refillthe refrigerant:
1>. Using thevacuumpumpforma vacuuminthesystem,via the jointofthelow-pressureprocesspipeonthecompressor,
thehigh-pressurepipelineisontheprocess pipeofthefilter.Applythevacuumpumpforapproximately20 minutes.Until
thevacuumislowerthan100Pa.Thensolderthecompressorprocess pipeofthefilter.Keepthevacuumrunningwhile
solderingthisjoint
2>.FillCooling systemwithrefrigerantviatheprocesspipe. (TherefrigerantisR134a.Regardingrefrigerantquantity
