TheAD7..isplannedforthemobileeffort. During thesettingup andtransportation
ofthedehumidifier,thefollowingitemsaretobeconsidered:
ØThatdehumidifiermust beinstalledsothattheaircancirculatewithout
obstructionthroughhim.Theairfilterandalsotheoutlet grilleofthefrontwall
must notbecovered.Theopenspacebeforetheoutletgrilleand theairfilter
must atleastconduct 1meter.
ØBeforeeverylocalalternationofthedevice,switchoffthedeviceat theon/off-
switch,pullthepowerplugfromthesocket andemptythewatertank!
ØTheairdryermustbemovedonlyusingtheprovidedwheelsand handhold!

formation,theappliancewillbedefrostedautomaticallyaccordingtothefollowing
principle:
ØAtemperaturesensormeasurestheconditionexisting inacriticalareaofthe

ØIttransmitsthesignalfordefrostingtotheDryLogic-electronic. TheDryLogic
findsout ifdefrostingisnecessary,and it willstartdefrost-modeon itsown.
