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 filters are fixed to the inlet retaining
caps
(fig.24)
. Only remove the filter to the
same side as plumbing entry leaving the
opposite filter/filter cap in position, failure to
do so will result in leakage.
• To gain access to the filter remove the cover.
• Unscrew retaining cap (the same side as water
supply) and filter should be attached (push
fit).
• If filter has seperated, use thin pliers to
remove.
• Inspect the o-ring for damage when the filter
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.
