7.4. UV lamp replacement. Average lifetime of UV lamps supplied is 9000 hrs. Replacement
is necessary after lamp stops functioning or at the end of manufacturer specified
lifetime.
Note. Open UV lamp operation can be checked with the visible light lamp switched
off (switch 1 is OFF). Use the indicator in the centre of recirculator cover (fig.
1/3) to check operation of UV lamp inside the recirculator. If indicator lights
from inside while switch 2 is ON, then the UV lamp is functioning.
7.5. Dust filter replacement. The dust filters (fig. 3/2) on either end of the UV recirculator
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.
