Always wear safety gloves when changing the UV lamp, in order to prevent that your skin
comes in contact with the UV lamp glass.
Wear directly a breathing protector when you are seeing that the glass of the UV lamp is
broken and ventilate the room well.
Contact your local Service organization to proceed as the proper disposal of the used UV
lamp. The Hg content in the UV lamp is so low so that no damage to the environment can
arise.
