
WARNING!ELECTRICALSHOCKHAZARD.Alwaysunplug(isolatefrompowersupply)toprevent
electricalshockexceptwhereelectricaltestsarespecified.

WARNING!IMPROPERSUPPLYORCONNECTIONCANRESULTISRISKOFSHOCK.
Connecttoa15amp120V60Hzproperlygroundedoutlet(GFIisrecommended).Ensurepolarity
iscorrectandalwaysusea3‐prongoutlet.Consultaqualifiedelectricianifyouhaveany
questions.

WARNING!USEONLYWaterlogicSUPPLIEDPOWERCORD.Locatesystemwithin5feetof
powersupply.Neveruseanextensioncordoradapter.Donotuseadamagedpowercordor
plug.Keeppowercordoutofheavytrafficareasandawayfromheatsources.Donot,underany
circumstances,removegroundprongoralterthepowercord.Neverpullthepowerplugfromthe
outletwithawethandorallowtheplugtogetwet.Failuretousethesuppliedpowercordwill
voidULCertificationandWarranty.

CAUTION!INDOORUSEONLY.Neverexposetodirectsunlight,heatsources,orambientair
temperatureabove37°C(100°F)orbelow2°C(35°F).Installindoorsandkeepunitawayfrom
excessivehumidity.Neverexposetofreezingtemperatures.Ensurethereisadequateclearance
aroundtheunittoallowrefrigerationsystemcondensertodissipateheat.Warmerenvironments
requiremoreclearancearoundtheunit.Minimumclearancearoundallsurfacesofthemachineis
2‐inches.Installswheretheambienttemperatureexceeds27°C(80°F),requireaminimumof4‐
inchesclearanceforproperheatdissipationandefficientoperation.

CAUTION!USEAWATERPRESSUREREGULATOR.Waterlogicwillnotberesponsibleforinjuryor
damagecausedbyexcessivewaterpressure.Operatingpressuremustbe40psito60psi.Be
awareanyofpotentialpressuresurgescausedbybuilding/municipalpumpingstations.

CAUTION!USEUVSTABILIZEDSUPPLYLINES.Feedwaterover37°C(100°F)candamagethe
treatmentcomponents.Waterblockdevicesandexternalleakdetectorsarestrongly
recommended.Locatetheunitasclosetothewatersupplyandtheelectricalconnectionsas
possible.Locatetheunitasclosetothewatersupplyandtheelectricalconnectionsaspossible.
Immediatelyisolateorclosewatersupplyvalveandcontactservicerepresentativeifleakis
noticed.

WARNING!STOREANDTRANSPORTUNITEMPTY.ALWAYSSANITIZEBEFOREUSE.
Theunitmustbecompletelydrainedandsealedbeforestoringtoavoidstagnationandreduce
microbiologicalcontamination(potentialbacterialgrowth).Sanitizebeforeusetoeliminateany


Pre‐installationandsanitizationproceduresasprescribedinthismanualmustbeperformedbefore
installingtheWL7FWWaterPurificationSystems.

AlwaysinstallindoorsandplacetheWaterlogicWL7FWWaterPurificationSystemonafirm,flat


1. Attachthewatersupplylinetothe1/4”feedwaterinletbulkheadfittingonthebackoftheunit.
Waterlogicrequirestheuseofawaterpressureregulator.Waterfeedpressuremustbe
between40‐60psiand2lpm(0.5gpm).Turnonthewatersupplyandcheckforleaks. 

2. ChecktoensurethatbothPower(Red)andHeater/Compressor(Green)Switches
areintheO=OFFposition.
NOTE:SwitchhasinternalLEDthatilluminateswhenplacedinI=ONposition. 

3. ConnectthepowercordtothebackoftheWaterlogicWL7FWWaterPurificationSystemandto

16. MovetheWaterlogicWL7FWWaterPurificationSystemintoitsfinaloperatingposition.Be
surethataminimumof2”clearanceismaintainedaroundboththesidesandthebackofthe
unit.Thisisimportanttoallowproperairflowandheatexchangeofrefrigerationsystem.

17. Levelunitusingtheadjustablefeettolevelifnecessary.Neverinstallonincline.

18. WhentheunithasreacheditsHotTempSetPoint,ensuretheheatercyclesoff.

19. WhentheunithasreacheditsIceBathSetPoint,ensurethecompressorcyclesoff.

20. Oncetheunitisatthetargettemperature(s),samplethewatertoensurewatermeets
