Thoroughly cleaning the unit

 C
Open and remove the filter lid from the filter housing (C2). Unlock and remove the inner cover (C4). Press both en-
gagement hooks at each of the foam filter holders sideward, then remove holders including foam filters (C5). Remove
the foam filters from the holders and clean with clear water. Open the cover cap at the cleaning outlet and clean filter
housing, inner lid and cover with water. Reassemble the filter in the reverse order. Arrange the foam filters in water
flow direction: Coarse foam filters (blue) first, then fine foam filters (red). Screw the cover cap back on again and start
the unit up ((→ Start-up).
Clean the UVC clarifying unit
 D
Open and remove the filter lid from the filter housing (C2). Turn the unit head of the UVC clarifying unit counter-clock-
wise against the stop, then carefully pull off (D1). Loosen the self-tapping screw until the the screw tip is sunk in the
housing of the clamping screw (D2). Undo the clamping screw by turning counter-clockwise, and remove the quartz
glass including the O ring forward with a slight turning movement (D2). Remove the O ring from the quartz glass, clean
and check for damage. Clean the quartz glass outer face with a moist cloth and check for damage. Thoroughly clean
the inner and outer surfaces of the housing. If necessary, replace the UVC lamp (D3).
Reassembly: Push the O ring against the collar of the quartz glass, press the quartz glass into the unit head against
the stop, fit the clamping screw and hand-tighten (D4). Tighten the self-tapping screw (D4). Check the O ring at the unit
head for damage, fit the O ring and push the unit head carefully into the housing while exerting light pressure (D5). En-
sure that the tenons at the housing engage in the grooves of the bayonet closure. Turn the unit head clockwise up to
the stop while applying slight pressure, so that the two arrows on the unit head and the housing meet (D6).
