is necessary after lamp stops functioning or at the end of manufacturer specified

off (switch 1 is OFF). Use the indicator in the centre of recirculator cover (fig.

with the hidden UV lamp should be checked monthly and cleaned or replaced when
they become clogged. To check, replace or clean the filters, simply unclip the covers,
fit a new filter if necessary or rinse current filters in water, dry and place back. Clip
covers back in place.
