Positioning/Mounting Before operation, the unit must be placed on a safe non-slip surface, or fitted horizontally on the wall. Mounting the wall bracket - Drill two 6 mm holes aligned horizontally with the mounting holes in the wall bracket. - The bracket can now be mounted on the wall, ensuring that it is securely held in place. - Fit the housing by sliding it down over the bracket until it is heard locking into place. When positioning the insert, make sure that the lower part of the insert rim is placed on the side studs of the lid. This will ensure that the insert is lifted up - Afterwards, use the pressure regulator to select the desired pressure setting (1 = low, 7 = high). We recommend starting with the lowest setting 1, especially if the user is susceptible to bleeding gums, or if the water jet is being used by children. - With your head held over the sink, guide the jet attachment to your teeth and gums. When the water control slide switch is pushed up, the water is forced through the jet nozzles and will run from the slightly opened mouth into the sink. [. . . ] Always remove the jet attachments after use and clean them thoroughly under running warm water. Carefully wipe them dry afterwards and replace them in the storage unit. Make sure that the power unit is completely dry before is replaced to the charging base. [. . . ]
