Fix the orange protection screen to the front of the epiilluminator with the two provided screws.
3.8 Mercury lamp insertion and replacement
Disconnect any cable from the epiilluminator. Loosen the lock-screw on the top of the lamp housing.
The lamp holder will come out with the door.
LAMP
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 in place.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 supply. 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.
