3 Safety Guidelines
Thefollowinggeneralguidelines,togetherwiththeinstructionsprovided
throughoutthisguide,ensureusersafetywhileoperatingandmaintainingthe
DT3CleanStation.If the system is not operated as specified, the user's
safety might be compromised!
• NeveroperatetheDT3CleanStationwhilethecoverisopen.
• Thepowercableshouldbeconnectedataneasilyaccessibleelectricsocket
neartheDT3CleanStation.
• DonotmovetheDT3CleanStationsothatthepowercablebecomestautor
disconnectsfromthepowersocket.
• AVACgroundfaultinterrupt(RCD)mustbeused.
• OnlyoperatetheDT3CleanStationwhenwearingneoprenegloves,safety
gogglesandaprotectivemask.
• Makesurethattheroomisproperlyventilated.Theventilationsystemshould
changetheairatleastfourtimeseveryhour.
• Removepartswiththesuppliedbasketorwithsteelorplastictongs.Donot
usealuminumtongswhenthecleaningsolutionisintheDT3CleanStation.
• NevermovetheDT3CleanStationwhenthereisliquidinthetank.
• Placingpartsinthetankraisestheliquidlevel.Monitortheliquidlevelofthe
tanktopreventoverflowing.
3.1 Alkaline Cleaning Solution Safety Instructions
Wearthefollowingprotectiveclothingwhenworkingwiththealkalinecleaning
solution:
• safetygoggles
• protectivemask
• nitrilegloves
• bootsorclosedshoes
Dependingonhowyouplantohandlethealkalinecleaningsolution,the
suggestedprotectiveclothinglistedabovemightnotbesufficient.Consult
yourcompanySafetyOfficerbefore handlingthesolution.
3.1.1 Preparing the Alkaline Cleaning Solution
Alwaysaddcausticsodatowater.Neverpourwaterontocausticsoda.Mixingit
withwatergeneratesheatthatcouldigniteothermaterials.SeeDOC-08380,
"WorkingwithAlkalineCleaningSolution".

3.2 Waste Disposal
Fullycuredmodelspresentnospecialsafetyorhealth-relatedissues.However,
checkiflocalregulationsregardcuredandpartiallycuredresinsashazardous
industrialwaste,andcomplywithallapplicableregulationsgoverningtheir
disposal.
Disposeofthealkalinecleaningsolutionaccordingtolocalregulations.

4 Installation
4.1 Selecting a Location
Prepareaninstallationareathatmeetsthefollowingconditions:
• alevelandstablesurface,whichisabletobeartheloadofthecleaningstation
(45.4kg/100lbs)
• nearasinkordrain
• nearapowersocket
Donotplacetheunitsothatthepowercablebecomestightordisconnects
fromthepowersocket.
• atleast15cm(6inches)clearanceoneachside
• roomtemperaturebetween18°Cand25°C(65°F-77°F)
Recommendations:
• anon-slipfloorbecausewatermaydripfromcleanedmodels
• anearbysourceofwater
4.2 Connecting the Drainage Hose
Toconnectthedrainagehose:
1. Connectastandard¾"gardenhosetothehosefittingatthebackoftheunit.

Figure1Drainagevalveandhosefitting
2. Insertthedrainagehoseintoadrain,sink,orcontainer,accordingtolocal

7 Troubleshooting
7.1 The Control Panel is Blank or the Cleaning Station Does
Not Run
• Checkthatthewaterlevelinthetankisnotbelowapproximately2.54cm
(1inch)fromthetopofthetank.
• Checkthatthecleaningstationispluggedintoawallsocketandthatthe
socketislive.
• Checkthatthecleaningstationisturnedon.
• Checkforablownfuse.
Whenreplacingfuses,alwaysdisconnecttheDT3CleanStationfromthe
wallsocketandkeepthepowercableinview,sothatitisnotaccidentally
pluggedbackin.
Tocheckandreplacethefuse:
1. Disconnecttheunitfromthewallsocket.
2. Locatethefusesbehindthetank.
3. Unscrewthefusecovers.

Figure7Fuses
4. Checkthefuseswithanohmmeter.
Note: Ablownfuseusuallyindicatesthatthereisanelectricalfault.
Tochecktheconditionofthewiring:
1. DraintheDT3CleanStationandtipitsothatitisrestingonitsleftside(when
viewedfromthefrontpanel).
2. Inspectthewiresunderthecleanstationandcheckthattheyareundamaged.

DT3 CleanStation
DOC-01121 Rev. A 3-16
