which protects the internal mechanisms of the shower unit and the handset. If the performance of
the shower deteriorates (ie flow reduction occurs) then it may be necessary to clean the filters.

Remove the shower cover as detailed in note 7 on page 4.
The cover will be connected to the PCB via a floating lead.
Carefully pull the lead from the PCB.
DO NOT let the front cover hang by the lead
as this will damage the PCB.

Ensure that both “O”-Ring seals are fitted to
the filter cap and reassemble cap using
