Beforestarting-upthedehumidifier,checkthatall
electricconnectionsaremadecorrectly.
IfthisisOK,turntheselectorswitchtotheposition
youwant:
"MAN"=continuosoperation
"AUTO"=automaticoperation
"0"=switchedoff
Theposition"AUTO"istobeusedwhenoperatedbyan
externalhygrostatorotherexternalcontrolequipment.
Pos"AUTO":
Ifitdoesnotstart-up,itcanbecausedbythehygro-
stat.Iftheactual%RHislowerthanwanted,thehumi-
distatisbroken.
Thiscanbecheckedlikethis:
-adjustthehygrostatto20%RH,andthedehumidifier
shouldthenbeoperating
-adjustthehygrostatto90%RH,andthedehumidifier
shouldstopoperating.
Airflowsshouldbeadjusted.
Thedryairflowshouldbeadjustedforthenominal300
m3/hforobtainingdatafromthecapacitydiagram.
Iftheinstallationisnormaldehumidificationofa
roomfor40-70%RFitisacceptablethatthedehumi-
fierisfreeblowing(withoutadjustment).
Iflowerdewpointsarewanted,youneedtoadjustthe
dryairflow.
Reg.-airflowalwayshastobeadjustedforthenominal
90m3/h.Thedamperinstalledinthereg.-inletduct
systemisforthispurpose.
Ifstandardreg.-ductsetisused,thereg.-airflowis
correctwhenthedamperisadjustedfor15DGclosed.
Withtheelectricalsettingsandairflowsadjusted,the
dehumidifierwillthenoperateautomaticallybymeansof
theinternalcontrol-andsafetyfunctions-controlled
byanexternalhygrostat.
