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.

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.
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).
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.
Ensure that the UV shutters are still open (rotate the motor dampener if they are not).
Prior to installing the UV lamp bulb, use the cleaning wipes provided in the replacement kit to clean it.
Pick up the new bulb by its ceramic ends.
Insert the bulb into the retainer clips one at a time, ensuring that the bulb is centered and seated firmly into the clips at both ends.
Reconnect the bulb power connectors and tighten the screw locks.
Rotate the two UV light shields clockwise back to the closed position so that they are parallel to the end plate.
