Press the head onto the filter cartridge in a firm motion,
pressing the entire surface evenly, so that no gap remains between
the filter, and the head. When installing the head, the cartridge is best
placed on a stable surface, for example: the bottom of the cabinet or
on the floor. Make sure that the locking button is as extended as it was
before the head was connected to the filter. (pic.1)
Set the filter in position D.
