How to Replace the Lamp Bulb

Procedure
IMPORTANT
Wear cotton gloves. Avoid bare skin contact with the UV lamp bulbs.
When heated, compounds from the skin can form permanent etching on
the surface of the UV bulb. A contaminated bulb may fail prematurely.
1.
Before you insert the new UV bulb and replace the lamp housing, open the
UV shutters and use a lint-free cloth soaked in isopropyl alcohol to clean
the reflector surfaces.
[153] Clean lamp housing reflectors
NOTE
If the reflectors are not cleaned at least with every bulb change, the curing
ability of the lamps will decrease (See Customer Application bulletin 38
for more details).
2. Use the lint-free cloth soaked in isopropyl alcohol to clean both sides of
the quartz window in the bottom of the UV lamp housing bucket.
3.
Ensure that the UV shutters are still open (rotate the motor dampener if
they are not).
4.
Prior to installing the UV lamp bulb, use the cleaning wipes provided in the
replacement kit to clean it.
5. Pick up the new bulb by its ceramic ends.
