Disconnect
installing or replacing the bulb.
•
The bulb has an anode and a cathode of
different sizes. Respect the polarity during
assembly, respecting the bulb dimensions.
•
Do not touch the bulb of the lamp with bare
hands to leave no traces of grease on the
bulb. If this happens, clean the bulb with a
soft cloth before turning on the lamp.
•
The bulb has an average life of about 200-250
hours: a time counter and a voltage indicator
are shown on the bulb power supply. Replace
the bulb when the hour count exceeds 250 or
if the voltage drops below 4.5A.
•
During use, the bulb, the lamp housing and the surrounding environment become hot.
•
Before replacing the lamp, switch off the power supply, disconnect all cables and wait for the bulb
and the lamp housing to cool.
•
After switching on the bulb, wait at least 10-15 minutes before switching it off.
•
After switching off the bulb, wait for 5-10 minutes before switching it on again so that the mercury
vapors have time to condense.
•
The bulb contains ultraviolet radiation that could be harmful to eyes and skin. Always look at the
bulb arc through the provided orange screen.
