

Preparingforuse(important)
Therinseaiddispenserisfittedonallmodels,thedetergentdispenseronlyonsome.
Ifbothdispensersarepresentputtheexternaldetergentandrinseaidcontainersinplaceand
inserttherespectiveintakehosesontherearoftheapplianceintothem.
Redhose:detergent
bluehose:rinseaid



Beforeinsertingthehosesintothecontainers,fittheweights(needed
toensurethattheyalwaysdrawinliquidfromthebottomsofthe
containers)andthefiltersontotheirendsasshown.
Ifthedetergentdispenserisnotfactory‐fitted,itcanberetrofitted
