Remove lamp housing and disconnect UV
lamp connector
1 Loosen the three thumbscrews that secure the
lamp housing to the monochromator casting.
While loosening the last thumbscrew with your
right hand, support the lamp housing with
your left hand.
2 Bring the lamp housing towards you.
3 Follow the UV lamp's wires to locate the
connector that links the wires to the internal
circuit board.
Note: If the connector is not secure in its socket,
secure the connector, install the lamp housing
and visible lamp, and start the detector to
determine if the loose connector was the
problem.
4 Detach the UV lamp connector. You'll have to
squeeze together the top and bottom of the
connector to remove it. As you remove the
connector to the old lamp, notice the
orientation of the connector.
Remove old UV lamp and install new UV
lamp
1 Loosen the three thumbscrews that anchor the
UV lamp to the top of the lamp housing.
2 Grasp the UV lamp by its base and remove the
lamp from the lamp housing.
CAUTION! Always handle the UV lamp
by the base, avoiding contact with its glass
window. A hot lamp can cause a severe burn,
and fingerprints can etch the window. To clean
a lamp, use a soft cloth moistened with alcohol.
3 Make sure the replacement lamp is free of
fingerprints and other blemishes.
4 Install the replacement lamp.
