11.2Ifthedehumidifierisnotoperatingitisprobablythe
externalhumidistatwhichhasbroken.
Thisisanormalsituationwhenthedesiredhumidityis
obtained.
Tocheck:adjustthehumidistatfor20%RH,andthe
dehumidifiershouldstartoperating.Adjustagainfor
thedesiredhumidity.
11.3Ifthedesiredhumidityisnotobtained,theproblem
canbethedehumidifier-ortheotherpartsinthe
totalinstallation(roomtightness,humidistat...).
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beltor
themotorhasstopped.
-byhandfeelthetemperatureofthereg.outletair,
andfeeltheairflow.Thetemperatureisdependingon
theinletconditions,butshouldbe40-60C.
Theairvelocityshouldbeapp.1,9m/s-Amp.meter
shouldshow4,1A.
IfitiscoldandAmp.metershows0A,theelectric
heatermightbereplaced.
Beforeopeningthedehumidifier,makesurethatthe
electricpowerisswitchedoffonthemainswitch.
Whenremovingthetopcover,Amp.meter,hourcounter,
selectorswitch,powerlinefilterandinternalter-
minalsareaccessible.
Whenremovingthefrontcover,rotor,gearmotor,drive-
beltandfansareaccessible.
Thefanisplacedintheleftsideofthecabinet.
Tobeunscrewedfromtheoutsidethroughtheprocess-
airinletopening(4screws).
Electricaldisconnectionontheterminalsplacedon
thebottomplate.
Thefanisplacedintherightsideofthecabinet.
Tobeunscrewedfromtheoutside(4pcsUnbrako).
Electricaldisconnectionontheterminalsplacedon
thebottomplate.
Theflexiblehose(Ø63)connectingtheinletairbox
totheheat-boxshouldberemoved.
Unscrewthetwoscrewsontopoftheshaftsfordepar-
tingplates.
DisconnectthewiringforthePTCheater,andthe
topdepartingplateinclusiveheat-boxandPTC-heater
canberemoved.
Nowtherotoranddrivebeltisfreeforremovingtoo.
