5.0 MAINTENANCE
Remove the old lamp or the plastic placeholder. Use protection glasses as, if handled carelessly,
there is a risk that the lamp may shatter and eject glass splinters. Thus, without touching the glass
part of the lamp, take out the fluorescence lamp from its box, taking care not to exert stress on any
part of the lamp. Put one end inside the flexible metal holder (observe that it fits only in one direction)
and then in the fixed one. Tighten the screws just enough to make it stay inplace. If you tighten them
too much the lamp may shatter. Put the lamp door with lamp assembly back in place and connect the
cable on the side of the epiilluminator to the power supply. Connect the mains cable of the power sup-
ply. Turn on the power supply using the power switch. Wait until the current display shows about 5.0
A. If the current falls below 4.5A, replace the lamp. You should now wait for at least 10 minutes before
aligning the lamp.
On the life time display you can read for how many hours the lamp has been in use. Replace the lamp
every 500 hours, even if it seems to work correctly, as otherwise it may shatter. Take care to let the
lamp cool down at least 30 minutes before opening the lamp housing. After having replaced the lamp,
press the reset button to reset the life time count.
