Maintenance
UV lamps replacement
• The UV lamp is fragile, take a great care while unpacking, moving and installing the UV lamp.
• Only clean UV lamps ensure uniform light emission. Before installation, ensure the UV lamps are
clean.
• Perspiration and sebaceous oil from the skin form white smudges which become etched on the quartz
surface of the UV lamp, when the UV lamp reaches its normal operating temperature. The etched
areas of the tubes inhibit the transmission of the desired UV energy.
WARNING: Make sure the unit is turned off and disconnected from the electricity supply, the
mains supply is locked off using a padlock or similar, and then a check made to ensure that the unit
will not run.
WARNING: Do not handle the UV lamps with bare hands. Wear cut resistant gloves.
WARNING: Always use safety glasses when handling UV lamps.
WARNING: UV lamps contain small amounts of mercury. Dispose them
according to local, state or federal laws and regulations.
WARNING: UVC light radiation is dangerous for human skin and particularly the eyes. Even a
short exposure time may cause burning in the lower skin layers and damages the eyes retina. Due
to the safety systems installed, it should never be required to check the UVC lamps by view the
UVC light directly when operating, maintaining or servicing the equipment. However, in case of
need it is mandatory to wear a welding helmet with at least shade 6, safety clothes and gloves.
NOTE: The UVA lamps have a built-in reflector which is applied in a semi-circle over the entire
length of the UVA lamp. The reflector is recognizable by the white no transparent color of the glass
in the tube. The reflector is designed to direct the light. When installing ensure, that the reflection
side is correctly located (non transparent section should be directed toward the plate).
WARNING: If UV lamp is broken, ventilate area where breakage occurred. Clean up with mercury
vacuum cleaner or other suitable means that avoid dust and mercury vapor generation. Take usual
precautions for collection of broken glass. Use cut resistant gloves and appropriate respirator.
Clean up requires special care due to mercury droplet proliferation. Place materials in closed
containers outside the building to avoid generating dust.
NOTE: When installing new UV lamps a burning-in of the UV lamps is recommended to get correct
performance and to stabilize them. Run the UV lamps prior to use the equipment (see the Service
Manual, chapter "Prior to start exposing/light finishing plates").
