ONLY FOR B-383FL
• Disconnect all electrical cables before 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 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 bulb, 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 emits ultraviolet radiation that could be harmful to eyes and skin.
