4 Productdescription
Aqua freehasdevelopedtheFLUSH2.0ushingsystem
toautomaticallyandindividuallyushwateroutletsthatare
rarelyusedorleftunusedforperiodsoftime.Itprevents
waterstagnationandthethreatofmicrobialcontaminationin
thepipes.
FLUSH2.0canbeeasilyinstalledonanytaps,showers
orotherwateroutletsinprivatehomes,publicbuildingsor
commercialestablishments.
Recommendations for ushing cycles and ushing
duration:
If drinking water pipes are ushed daily Aquafree recom-
mends a ushing duration of 5 minutes.
Howevertheprecisedurationdependsonthecrosssection
andlengthofthepipeandthewaterpressurealthough
referenceshouldalwaysbemadetonationalguidelinesfor
ushing.
IMPORTANT! Beforetheushingsystemisusedwitha
mixertaporsimilaritisimportanttomakesurenon-return
valvesaretted.
NOTE
IMPORTANT!Pleasereadtheseinstructionscarefully.
Themanufactureracceptsnoliabilityforanydamagethat
occursbecausetheseinstructionsarenotfollowed.
Forfuturereferencekeeptheseinstructionsinthecase
withtheushingsystem.
CAUTION
Iftheushingsystemisconnectedtoalow-pressure
systemsuchasaboilerthereisariskofpressurebuild
up,causingleakage.
Beforeinstallingtheushingsystemcheckthewater
outletandassociatedpipework.Ifgasketsorjoints
aredamagedorunsecure,theadditionalweightofthe
ushingsystemcancauseleakage.
Thebatteryoftheushingsystemlastsforoneyear.
Thedateofthenextbatterychangecanberecorded
onthedeviceitselfusingthestickerssupplied.
Intheeventofbatteryfailurethevalvefailsafeposition
isCLOSEDandthe“DELAY”,“FREQUENCY”and
“RUNTIME”LEDsonthedisplaywillashrepeatedly.
Whenthebatteryischangedtheushingprogramwill
returntoitsdefaultsettings.Therequiredprogramme
shouldbere-enteredandthenre-activatedbypressing
theSETkeyforatleastveseconds.
WARNING
Iftheushingsystemisusedwithoutnon-returnvalves
beingttedorworking,anybackpressurefromthe
hotwatersupplyriskscontaminatingthewholeofthe
drinkingwatersupplysystem.
Non-returnvalvesshouldbettedonboththehotwater
andcoldwatersupplypipestothetap.
Theushingsystemshouldnotbeusedwithout
functioningnon-returnvalvesinplace.

Installation:
■ Checkwhethernon-returnvalvesarettedinthepipes
supplyingthetap.
■ Removetheaerator(fromtaps)orunscrewtheshower
hose(fromshowers)
■ Toinsertthebattery,rstunscrewthetransparentcover
oftheushingsystemandremovetheblackbattery
coverbelowtheoperatingpanel.
■ Thenttheappropriatequick-tadapterwithsealing
gasket(thesetincludesthreedifferentadapters).
CAUTION
CAUTION
Ensurethattheadapteristtedtoaxedwateroutletsuch
asawall-mountedshowerorfree-standingtap.
Fittingattheendofaexibleshowerhoseisnotpermitted
becauseoftheuncontrolledoutowofushingwaterand
possibleresultantwaterdamage.
Whenthetransparentcoverisremovedtheunit
electronicscanbedamagedbywateringress.
Forthisreasonalwaysdetachtheushingsystem
beforeprogrammingitorchangingthebattery.
Ensurethatyoualwaysprogrammetheushing
systemandchangethebatteryinadryenvironment.
WARNING
Iftheushingsystemisusedwithoutnon-returnvalves
beingttedorworking,anybackpressurefromthe
hotwatersupplyriskscontaminatingthewholeofthe
drinkingwatersupplysystem.
Non-returnvalvesshouldbettedonboththehotwater
andcoldwatersupplypipestothetap.
Theushingsystemshouldnotbeusedwithout
functioningnon-returnvalvesinplace.

■Connectthesnapcontactoftheushingsystemto
thebattery.Removetheprotectivelmfromthebatteryif
necessary.Oncethebatteryisinstalledthesystemperforms
asystemcheckinwhicheachoftheLEDsashesoncein
turn.
■ Programtheushingdevice,ifnecessaryrefertosection
8.3.
■ Replacetheblackcoveronthebatterycompartmentand
screwthetransparentcoverbackintoplace.
■ Emptythewashbasinandcheckthatthewatercanow
awayfreely.Fixthewaterlevelswitchtotheinneredge
ofthewashbasinwiththeoatpointingverticallydown-
wards.
■ Wetthesuctioncupwithwatersothatitholdsrmlyto
thesideofthebasin.Ensurethatthecableisnothan-
gingdownandpullingonthesuctioncup.
■ MoistentheO-ringoftheFLUSHcouplingwithwater(for
easierandsaferinstallation);thenpushthecouplinginto
theadaptorwithaslightturningmovementandlockthe
FLUSH2.0inplacewiththeU-clamp.Checkthatthe
ushingsystemisseatedsecurely.
■ Turnonthetapandnowatershouldow.
■ Carryoutatestush(seesection8.3)
Regularchecks:
■Every4weeks:
 • Checkforpotentialblockingofthewashbasin.
 • Checkthatthewatercanowawayfreely.
 • Checkthatthelevelswitchiscorrectlypositioned,
securelyxedandtheoatabletomovefreely.
 • Ifnecessarypositionthelevelswitchandsuctioncup
correctly.Replacedamagedsuctioncupifrequired.
■Every6months:
 • Checkthefunctionoftheushingsystem:testthema-
nualmodeofdrawingwaterandcarryoutatestush,
seesection8.3.
■Yearly:
 • Replacethebattery,renewthebatterychangesticker
NOTE
CAUTION
Theushingprogramcannotbeactivatedifthebattery
voltageistoolow.Inthiscasethe“DELAY”,

batterymustbereplaced.
Ifthedrainisblockedorthelevelswitchwronglytted,
watercannotrunawaycreatingariskofoverow.
Makesurethatnoobjectscanobstructtheowofwater
andthatthewatercandrainawayfreely.
Ensurethatthesuctioncupiscorrectlyttedandsecurely

8 Programmingtheushingsystem
8.1 Operatingprinciple
DELAY:Preselectionofstartingtime/delaybeforethe
rstush
Example:DELAY=2h
Therstushbeginsin2hours.
FREQUENCY:Pausebetweenushes
Example:FREQUENCY=24h
Flushesarerepeatedevery24hours.
Theushingsystemiscontrolledwiththethreekeyslabelled
“SET”,“+”and“-“atthebottomoftheoperatingpanel.
8.2 Defaultsettings
Thedefaultsettingsoftheushingsystemareasfollows:
■ DELAY:  0minutes
■ FREQUENCY: 24hours
■ RUNTIME:  5minutes
Toactivatetheushingsystempressthe“SET”key
andholditdownforatleastveseconds.Successful
programmingisindicatedbytheashingofoneLED
fromtheleft-handrow.
TheLEDsareturnedoffafteroneminuteofinactivity.Ifone
ofthethreekeysispressedforthreesecondsthedisplayis
turnedonagain.
8.3 Examples
