CLEANING THE FILTER
CLEANING THE FILTER
It is recommended that the filter is periodically
cleaned in order to maintain the performance of
the shower. It is essential that this operation is
carried out by a competent person.
IMPORTANT: Before servicing, switch off the
electricity supply at the mains.
• Switch off the water supply at the isolator
valve.
• The inlet filter is situated inside the water inlet
fitting (g.21).
• To gain access to the lter, remove the cover
and bottom left trimplate.
• Unscrew the lter cap from the bottom of the
inlet pipe.
• Inspect the ‘O’ ring for damage when the
filter cap is removed.
• When cleaning the filter, DO NOT use a sharp
object as it will cause damage. It is preferable
to use an old toothbrush or similar.
• To reassemble, follow the procedure in
reverse.
• Make sure that the sealing ‘O’ ring is in place.
• DO NOT over tighten the filter cap on
reassembly.
NOTE: Full commissioning procedure will need
to be performed after cleaning of the filter - see
page 20 for information on commissioning
procedure.
