12.1Ifthegreenneonisnotilluminated,electricitysup-
plycouldbecut-offtothedehumidifier.Checkthe
externalfusesforthedehumidifier,andcheckthe
internalfuseFS1,5A.
Itcouldalsobetheneonwhichhastobechanged.
12.2Iftheyellowneon(HL2)isnotilluminatedevenwhen
thegreenneon(HL1)isilluminatedthethermostat
ST1mighthavebroken.PushthebuttononST1forreset-
tingthethermostat(placedclosetotheneons).
12.3Ifthedehumidifierisnotoperatingevenifthegreen
andtheyellowneonison,itisprobablytheexternal
hygrostatwhichhasbroken.Thisisanormalsituation
whenthedesiredhumidityisobtained.
Tocheck:adjustthehygrostatfor20%RH,andthe
dehumidifiershouldstartoperating.Adjustagainfor
thedesiredhumidity.
Alsochecktheselectorswitch,foroperationthepo-
sitionmustbe"AUTO"or"MAN".
12.4Ifthedesiredhumidityisnotobtained,theproblem
canbethedehumidifier-ortheotherpartsinthe
totalinstallation(roomtightness,hygrostat...).
Toverifythis,check:
-rotationofrotor?
-thedryairshouldbe15-20Cwarmerthantheinlet
mainair.Ifitiscolditcouldindicatethatthe
rotorisnotturningcausedbybrokendrivebeltsor
themotorhasstopped.
-byhandfeelthesurfacetemperatureofthereg.out-
letduct.Forcorrectoperationthetemperature
shouldbe40-60C.Ifitiscold,thethermostatic
switchmighthavebroken.Manualresetonthered
buttonplacedclosetothegreenneononthecabinet.
Ifitisveryhotitindicatesthattherotorhas
stopped.
