Unscrew the branch valve (12) and the attachment elements. Pull the clamps on both sides of the bottom strainer cas-
ing (2) to the side and lift off the top strainer casing (1). Remove the foam filter (3) and the UVC clarifying unit including
pump (20), and the fine foam filters (22), bio surface elements (23) and the gravel bag (24).
Clean the bottom strainer casing (2) and the top strainer casing (1) with clear water using a brush. Wash out foam fil-

agents as they would kill the micro-organisms in the different filter media. At the beginning, this entails a reduced filter
capacity.
